FAQ
Humming or growling that changes with speed, clunking when you take off, vibration, oil on the inside of the wheel or tire, and a hub that runs hot are common signs. A leaking wheel seal should be fixed quickly because it can ruin the bearing and contaminate the brakes.
It is not a good idea. Losing lubricant can overheat and destroy the bearing, and oil on the brake linings reduces stopping power. Have it checked as soon as possible.
On tandem axle trucks, both drive axles must be square to the frame and parallel to each other. When they are not, the truck dog tracks, tires wear fast and fuel economy drops.
Yes. We diagnose noise, vibration and leaks in the differential and repair or replace gears, bearings and seals as needed.
We work on light, medium and heavy duty diesel trucks, fleet vehicles, trailers and RVs, including Freightliner, International, Peterbilt, Kenworth, Volvo, Mack, Hino, Isuzu, Ford Power Stroke, Ram Cummins and GM Duramax.
It depends on the truck, the parts and what we find. We diagnose first, then explain the repair options and the price before any work begins, so there are no surprises. Call, text or use the form to get started.
