I used the Rear end shop many years ago and remember it as a positive experience. They also come…read morehighly recommended, and when you're getting ARB lockers installed you want people who know what they are doing. I went in pre-Covid and got a quote which was $3200. I lost that quote and they where unable to find it in their system. My new quote is $4200, but with out the other quote they can't explain why. I called around and found out that $4G to have both installed was the going rate. So I figured the $3200 quote was a mistake. Since I needed these installed prior to going to the Rubicon and my trip was approaching, I went with them, (and the other shop was saying they couldn't get it done when I needed it done by.) The day before my appointment I found out they didn't have the parts in and I wasn't going to be able to get the front locker. So I pushed my appointment back a week to make sure they had the rear in the store (since that was also going to take longer) before I I dropped off my Jeep. I was able to get the front locker delivered to me in 4 days after finding it on Amazon, so I'm not sure why they couldn't get one. (Maybe no profit for them if they get it at the amazon price like the general public instead of a likely discounted rate from a supplier, etc.) They had my Jeep for two days and I found out it would not be done by the end of day. They said that the seals in the front are different from the JK to JKU models and they got the wrong ones. I had to take a day off work and use 12hrs of my PTO because of this! Now on the third day I called at 11:00 am to see if the parts came in. I told Josh I needed this done by the end of day, and that I cannot miss another day of work- I said someone in town has to have the correct seals - He replied "he's waiting on UPS and if they could have gotten it local they would have, and waiting on ups is messing with him" So finally at 15:20 I heard back that I will get my Jeep back that day. I show up at just before 17:00 to pick it up. They had my Jeep out front and ready for me. I go to get my keys and I ask Josh so do I just turn on compressor and then flip switch for lockers? I find out at this point that they didn't install the airline or hook up the SPOD and compressor, even though I told them I had both. Josh told me ohh you wanted us to connect it. Normally people want to run there own air lines. That night I called and left a voice message for there manager or owner to call me. Thursday at 11am I called again and left a message with Josh, that I wanted the owner or manager to call me. Monday came around, and no phone call. I stopped by the shop at about 1600hrs and talked to Josh. I dropped off Jeep. I found that there was air leaking around both solenoids, luckily one of our club members is a mechanic and was able to help me. We found that there was nothing used on the threads to stop the air from leaking! We had to remove the manifold out of the jeep, and redo what was not done correctly. We also found that they were not tight. After properly installing the solenoids and re-installing the manifold we still had air leaking from somewhere. We found air leaking from the connection at the front differential because it was not installed tight enough!But we still had a leak so I crawled under the jeep and started to check the rear line, and when I found that it had burned through, they had ran the line so close to the exhaust that it burned through and I was left with two separate lines and two piece of melted tubing! This was under the jeep, so I could not stretch it to the manifold. We were able to use the propane line from my camping stove to do a "bush fix" with a couple of hose clamps. Sunday I had both lockers working and what a difference that made. Would have been nice to have that for the whole trail! I left a message about failure. 8 days no call back. I absolutely cannot believe that they are not even willing to return my phone call, after charging me almost $4,000, and me calling over 8 times. I cannot believe someone can own a business and care so little about the quality of the work, and even if for some reason some justification could be found for all the mishaps, with such little care for a customer's experience, and to not even have the common courtesy to return my phone call- this really undermines my trust in them, as they seem to just care about the money not the quality of the job and far less about their relationships with their customers. I will never use this shop again. It's sad because they used to have a good reputation. But now they over promise and under deliver... I cannot imagine they will stay in business long if they continue this behavior. As for my part, I will absolutely make sure that if I can save someone else the trouble with them I will- no one should have to go through this! Had to delete part of my review. To long per yelp.

They took advantage of me because they knew I needed my car for work they're horrible! The difference in Sammy's attitude from when I first bought the car in to get fixed... until I had it towed back to them because it was smoking after the day I brought it home, and they told me it was blown is horrific he is "evil...!"
