I won't repost it here for fear of their legal attacks. On this one you'll have to make up your own mind. I'll just say this, I have a CDL (Commercial Drivers License) and I can't afford to get sued over a legitimate complaint. I further believe that threats are a poor way to respond to the serious and legitimate concerns of others.

I am writing this review to caution other owner-operators and fleets regarding the service and lack…read moreof accountability at this facility. On November 25, 2025, I had bushings and new U-bolts installed here. Shortly after, the axle shifted, leading to catastrophic mechanical failure and approximately $9,000 in damages. When I called to resolve the issue and requested to speak with a manager, I was repeatedly denied access. Instead, I was told by staff that the manager "advised the driver" that the U-bolts required re-torquing. As I am both the owner and the driver, I can confirm that no such instruction was ever given. Furthermore, there is no mention of a required re-torque or mileage-based adjustment on my official work order or any provided documentation. It is disappointing to see a shop fail to stand behind its work and refuse to engage in a professional dialogue when a clear error in installation occurs. I would not recommend this shop to anyone looking for reliable service or professional customer support.
