Is your vehicle humming or whining while going down the road?  We rebuild differentials in house, whether it needs bearings and seals, gears, or ratio changes.  We do these all in the vehicle so you do not need to remove the whole axle.  We also replace U-Joints and can repair your driveshaft if it needs attention.  Please stop by with your vehicle to have us take a listen to the vehicle to see if it may be in your differential or someplace else in the drive train.
