Come in for a free rear end differential inspection. While you wait your automotive repair technician will inspect every inch of your rear end system. After the inspection you will be notified of any problems that need to be repaired or replaced.

Your rear end differential helps control the speed of your tires in a turn. Without it your vehicle wouldn't be able to make those smooth turns. Rear end differentials can cause problems if not properly maintained. The cause for rear end differential noise is due to internal gears rubbing together. Ignoring rear end problems can lead to major ware and tear on your vehicle which will eventually cause it to break down.

We repair and replace rear end differentials. Our service stops those annoying noises while your vehicle turns; we'll replace low differential fluid which helps stop the differential gears from rubbing together and wearing down.

Service is available for open differentials and slip differentials. We can also service locking rear differentials issues.

Allow your vehicle to have smooth and safe turns. Visit us or call one of our qualified technicians for rear end differential service.
