"I have a Jeep TJ that (like most) has been modified over the last 15 years. Lots of suspension modifications. With those changes, the geometry of the driveline and shifted quite significantly. I paid a handful of off-road shops in the area to fix those angles and alignment. None did it right, which was frustrating since I bought high-end suspension, including springs and adjustable control arms, etc etc. That is all great if it’s installed correctly. Mine wasn’t a d no other shops could fix it. Found Jantz Engineering and boy am I glad I did. PERFECTED the driveline angles and no more driveline noises. Jantz also went through the Jeep with a fine tooth comb to get it running right and safer for the road, and chased down issues that no other shops could. The Jeep hasn’t run this well (suspension + engine) since I bought it. If you modify your Jeep, do yourself a favor and either have this shop install it (right) or make sure you visit Jantz to fix other shops’ shortcomings. Very reasonable cost, very honest, and a great guy to boot. Thanks Jantz for fixing it the right way. And thanks for walking me through your Super Jeep (readers, you should google “Jantz super Jeep” - the real deal)."

"Very knowledgeable and capable mechanics, machinists and fabricators. They have one of the biggest presses in the area as well. I am pretty picky about the people I have work on my car -in the rare cases it's not me- as I use it primarily for roadracing/circuits and these guys do quality work. Doesn't hurt that they are good people too. Even helped me fix an issue with my truck that popped up right in their parking lot!"

"If you're looking for the best- get it done service, this is the place. Carl can make it work, and there's no one better with an axle or machine work. You'll likely pay a premium, but in my experience, the value exceeds the expense."
