These guys are the best , and honest as the day is long , don't hesitate to trust these guys with your truck

I have an LX470 (Land Cruiser) that I have taken shop to shop trying to diagnose a "clunk" that happens from drive to reverse. Within 1 hour they had an answer. Not only did they find the problem they informed me on how to address a few minor things easily that I was just tolerating to not waste money on a 20yo rig. Their knowledge was top notch! Hands down recommend! read more

Colorado Axle N Gear - Auto Repair Near Me - Denver, Colorado

We had a new rear end replaced recently in our Jeep Wrangler and these guys got us in and out in the time promised and for the price quoted. Very happy with these guys! read more

Took my new 2022 Tacoma Off Road in to change to 4.88 differential gears. I was extremely disappointed with the factory gearing on a automatic transmission (my 2013 was a manual). I researched this problem and found out this is a common complaint. Too bad I did not know this when the truck was purchased. Colo Axle N Gear said it was a common complaint and recommended the 4.88 option especially at this altitude and stock tire size. They have done MANY of these conversions. The job was performed in 6 hours. GREAT! The gearing was not extreme and felt just right. I feel sorry for owners who do not change their gearing. I would recommend Colorado Axle N Gear whole heartedly with out exception. Edward D. Denver, CO read more

Al and his son are awesome! I highly recommend them. I had taken my Jeep to Dave off of I-70 and Harlan for a gear upgrade. It was a gear downgrade. Colorado Axel and Gear was recommended by a friend after I realized something wasn't right when I got my Jeep back. Come to find out nothing was right until I took it to Colorado Axel and Gear. Now it runs like it use to. It is my dream Jeep again. No longer am I afraid to drive it out of fear that it will break down. Al and his son are wonderful to work with and keep you updated on the status of your vehicle. So very happy and highly recommend. read more

When the rear axle on my 3/4 ton pickup suddenly started making noise I was really bummed. I figured my next weekend camping trip was canceled. And I assumed I would be out of Thousands of $. Then I contacted Colorado Axle n Gear. I was able to drop my truck off the next morning, and they had the complete axle rebuild done by the end of the day. Complete with all new OEM bearings, seals and a new Ring and Pinion. All at a very reasonable price, a lot less than expected. They even replaced my leaking front pinion seal for only the cost of the seal (labor was free). Al took the time to have me drive the truck to be sure I was satisfied. He then showed me all the old parts and explained why they needed replaced and what may have caused the failure. It has been a long time since I left an auto service place happy. I usually dread the experience. Instead, I walked away completely satisfied, confident that the repairs were done right. Colorado Axle n Gear is a local family run business that you can definitely trust. These guys are the best. Highly Recommended! read more

If you want your truck re-geared, go nowhere else but here. If you do you are wasting your time. This place is the best! Service, price, customer service are all top notch! Al Sr and his staff have my business without question!!! read more

Had my Jeep re geared for 37" tires. They did an amazing job and was able to pick it up later that same day! They used Spicer gears because they are the only gears still made in America. Father and Son, who know their business. read more

Sadly yelp does not offer enough available stars for this business. Colorado Axle and Gear is one of the best shops there is!!! They are knowledgeable, fair, kind and treat everyone not like a customer but like a family. We had work done on one of our jeeps and will not go anywhere else again. This winter we will tear down the race car for a better gear ratio. That's one of the most amazing things with this company they help find a solution that's right for you not what going to make them the most money. Albert and Al are amazing. I cannot wait to continue to have you as part of our next build. read more

You won't find a better company to work on your vehicle than this one! I had them repair the differential on my Toyota 4Runner and I am SO pleased with them and the job they did. They do great work, their prices are great, they are HONEST, and they are great people, too. The perfect combination of greatness! I learned something else valuable through working with Colorado Axle - going to a specialist to work on my truck is something I will now look to do in the future instead of any old mechanic. read more

I recently purchased my first 4x4 campervan (Ferd E350 with V10) and while incredibly excited with the possibilities my new shaggin wagon presented, after our first family vacation (3500 mile Canadian Rockies roadtrip) I was less than impressed with the anemic nature of the van's performance. I mean it's a V10, right? So I started seeking solutions. After discussing the issue with a few of my gearhead buddies, I decided to look into switching the gearing of the van. After some research on how gearing works and dropping by to see Al at Colorado Gear and Axle, he discovered that the current axles in the van most likely came from a plains state vehicle as it was horrible trying to pull even the lightest grades in the mountains, which is where it's going to be spending most of it's time. Oh yeah, I also had to put bigger tires on as well for that tough guy look which of course also makes a big difference in performance. Anyway, Al talked me through my options and convinced me that a switch in the gearing would really wake up the van. And DAMN was he right! A month and 2 more road trips later and I couldn't be happier. The van flies up the mountains as it should, even towing a moderate trailer. His incredible customer service, promptness in completing the job, and even follow up to ensure I was happy (when was the last time a mechanic did that?!) will keep me recommending Al for any axle work from now til eternity. Can't say enough positives about my experience. He delivered all that he promised and can honestly say he exceeded my expectations. THANKS AL! read more

These guys make it easy. Our driveshaft was going bad. All of the driveshafts online that you can purchase new are all Chinese and I've been told by many people I trust that Chinese parts are bottom of the barrel. Dealer charges $2000+. The auto shop I took the car to wanted $1800 total. Coming here I paid $465 tax included and all it cost me was 2.5 hours to remove and 2 hours to replace. It solved the issue, nice and quiet. Their service is professional, they are very nice and helpful, and their parts come with a warranty. I will remember this place and return in the future. read more

Brought in my Mustang to change out the rear axle for 4.10 gears. Service was excellent, fast, and less expensive than anyone else around. My dealership wanted an obscene amount of money, as did some place in Boulder. CO A&G had me out in 2 1/2 hours, and the price was under $500 for labor and bearings (I had my own gears). I've had no problems since the installation and love the new 4.10s. HIGHLY RECOMMENDED read more

These guys are the best gear guys around. If they can't fix it they never charged me and the bill is always lower then he quoted. Don't even think about going anywhere else. Not even those ridiculous franchise dealers. He even takes the time to explain what is going on by showing you with his examples in the showroom. read more

I brought in my 2004 Tundra to Axle N Gear to diagnose my rear differential grinding. Al took my truck on a test drive and went under to check the diff fluid. He determined that my clutch just needed to be lubricated. Al didn't charge me a dime for the diagnostic and after driving my truck home, the problem seemed to have be fixed. Great service and I will definitely be recommending this auto shop because of their honest and true diagnostics and friendly service. Thanks Al! read more

After reading several reviews about AL and his shop I decided to give them my business and man I don't regret it at all. Their knowledge and experience were top notch. I had just gotten a lift installed on my jeep and had a noticeable power loss which Al was able to correct for me by upgrading my differential gears to 4.88 and what a difference it made. Not only do I have my power back I also got my MPG back as well. One thing I loved about Colorado Axel N Gear is how quick the turn around was. I dropped my jeep off at 7:30am and had it done and back in my hands by noon on the same day. I would recommend Al and his team to anyone who needs to have their differentials repaired or upgraded. Hands down one of the best shops I've ever had the pleasure of working with. Last but no least Al quoted me a price that was half the cost of a shop in Boulder and he was good to his quote as he kept the final cost right around the original quote with no hidden added extras. 5 stars is not enough for Al and his team. I will return in the future for all my axle and gears needs. Thanks again Al for the top notch service you provided me. Thanks again read more

Great service,Al genuinely cares...he is good people!thanks for the great service!!!he found some very hard to find parts at a fair price.

Great run business - Quality work, excellent products, and fantastic service. After one year on my rear locker, I have zero complaints. I called Al today for a friend and he remembered everything about the job, me, and the application for my rig - I felt like family. Thank you Colorado Axle N Gear. Donny Z read more

Use Colorado Axle and Gear. They do good honest work and personally care about people.

I usually do all my own work, because rarely do you get attention to detail and things done right. Axle set-up is one thing that has always made me second guess my own work. Another shop gave me a low ball price but didn't properly set up the rear end in my Bronco and the bearings failed. Al and his son took it apart in front of me and showed me what was done wrong and why. Great attention to detail and great guys. Replaced all the bearings and set it up right. Had the truck back the same day. Awesome experience. read more

I have a classic car with a leaking pinion seal. I called Al and he got me in fixed and on the road in no time. I can't say enough good things. Al and his workers were very helpful, knowledgable, and friendly! I got in and out faster than I expected and for less than I had expected as well (always a nice surprise). HIGHLY Recommend! read more

Al is the man. Fixed my van for a great price and then fixed a nagging issue on my jeep as well! Can't say enough good things about this shop. read more

Al & Jeff are AWESOME!!! I went to a shop 2 blocks from me and was given poor customer service and charged $50 for a quote after I told them what my problem was. The mechanic there told me it was a track bar when it clearly wasn't. Had to point that out to him...as well as tell them what axle I had. Talked to Al over the phone and explained my situation and he quoted me on the spot. Brought it in and took him and Jeff 1.5 days to complete the job (2.5 days faster than anyone else said). They gave me a great price and Al even went out of his way to get me a key for my locking lug nuts (which I didn't know I had cause I just bought my rig)! Customer service: 10+, Price: 10, Quality (from what I know): 10, Location: 4 (far from me but way worth it!!!). Over-all experience: 10 and telling anyone who needs axle work to go see Al!! Like I told Al & Jeff, I hope I never see them again, but if I do I'm glad I know they are working on my '02 Grand Cherokee off-road rig!! Thanks guys, you were freakin' awesome!! **Edit** Also talked to Al about the famous Jeep "Death Wobble" and he gave me some good advice as well as a good alignment shop for it. Helpin' out after gettin' paid means a lot to me! read more

This is an honest shop with skilled mechanics. I was having a problem with my rear differential for a few months. I switched from conventional gear oil to synthetic gear oil. After listening to a high-pitched whining noise for about a month, I brought my truck into the dealership where they switched back to conventional gear oil. My rear differential then started making a grinding noise around corners as if it didn't have any limited slip additive. I brought my truck back to the dealership where they had no luck fixing the problem. I put some miles on my truck thinking that the oil just needed to work into the clutches, but I had absolutely no luck. After putting 5,000 miles on my truck with these problems, I finally called this shop. Al listened to the problem and said that the truck could have worn out the bearings among many other problems. Furthermore, I was hearing a loud clanking noise when going over bumps and making hard u-turns. I asked him to look at the front wheel bearings. I thought that the problems would cost over $700-$1,000 to repair based on past experiences and Al's preliminary estimate. Thankfully, Al fixed my truck for less than $100! This is an awesome shop. The mechanics are honest and knowledgeable. The shop is clean, too. All the problems with my truck were resolved. I couldn't recommend this place enough and I know I'll be back. read more

These guys are great. Even though they couldn't do the repair they called a buddy and I was able to get it repaired and back on the road same day. BIG THANKS! read more

Got my Jeep Wrangler re-geared and a new locker installed there today. I can't say enough good things about Al and his crew. It was the kind of experience that makes you happy you can do an online review of them so other people know about how great the experience was. Al and his crew went above and beyond to make sure I knew enough to make informed choices about all the work done, taking time to make sure everything was not just right, but geared right for how I planned to use it. The work was well done, the price was by far the cheapest around (about 30% below most quotes) and they had me in and out in a little over half a day (for both axles!). They were honestly interested in making sure I was happy and taken care of. Al told me multiple times they stand behind their work, so come back if I had any issues. Another thing, his crew really seems to respect and like him. You can tell he is legitimately an all around great guy who is good to his employees. read more
