One shop would not even give me a range even though it was going to cost me $250.00 to have it towed. Lynn at Mr. Deisel described the process and gave me a range from $1100 to $5000 to have it fixed. George was able to get my truck in the next day. He fixed my truck before this cold weather hit, just three days. It may have been shorter, but Lynn was trying to help with the insurance claim. Cost.. $1,100.00. They had amazing matter of fact customer service, and my truck is running well. Thank you so much. Renee H

We pulled over to Loves Fuel depot on I-25 and they recommended Grabers Diesel Repair. The Graber team removed the tire, the metal, and used a repair plug but the hole diameter was too large so they installed the spare tire. Then they called several tire shops in Cheyenne and found a Firestone tire shop which was open. All in all, Grabers' spent over an hour with us and didn't charge for their time and materials. We are truly blessed by their kindness and support. I strongly recommend anyone in need of support to visit Grabers Diesel Repair. Barry

Graber mechanic inspected pads and rotors then called me to say I did not need to replace anything, I must have picked up some road dust, maybe while driving through New Mexico and Texas, but anyway they saved me $1500. The courtesy inspection they perform that is included with oil/filter change is very thorough. Antifreeze topped off, brake fluid topped off, transition fluid inspected, rear differential found pinion leak, topped off, took nearly three quarts of fluid. Also check all running lights, plus lube job So gratefully for the Graber team helping us put while on an extended rv trip.

After doing an in-depth inspection and no issue being found, Nate asked if he could drive it around to see if it happened again. After no issues during his drive, he brought it directly to me at the hotel we were at. He gave us ideas on what might have been the cause, answered all my questions (despite some of them probably being ridiculous!), and said they'd be happy to help if we have any issues in the future. These guys went way above and beyond amd showed true concern for our needs and car issues versus us just being a number and a paycheck. Words can't describe how grateful I am for their help and patience (and the fact that it didnt cost an arm and a leg just for no issues to be found!).

Then justified charging "book rate" 6 hrs. labor, $150/hr, for a job he finished in 1.3 hrs. He ripped off 2 stranded senior citizen vets.

I will be telling everyone we meet traveling around the country to avoid this immoral greedy thief. If he had any conscience he would refund the 4 hrs. of labor he stole from me. One day he will reep the consequences of ripping people off.
