I spun out last winter (live in IL) in to a ditch and my blazer was in a bind. It was sitting crooked in the ditch where if you were looking from behind the passenger side wheel was shoved up inside the wheel well. The driver's side was hanging down into the ditch. I got a hell of a vibration after and then I replaced the right side axle (it was bent). When I went to change the axle I looked closely at the center section and my spider gears look to be ate up more than normal. I drive on the highway to school everyday about 20 miles and it beats the **** out of me. Any ideas?

 

First thing, tires are balanced?

 

drive shaft make contact ?
Ujoint ?

 

After bending a axle shaft I would check that rim and also pinion bearing and u joint too.

 

Hey guys, my tires are balanced (All 4 Brand New). I myself and I had the guys at Firestone check to see if my rims were bent. I didn't think they were and neither did Firestone. I have checked the driveshaft as well, its true, no bend to it. However, the pinion bearing is vey loose. I don't think its a u-joint, the vibration for one is to violent, and two I have had them go out before and know what they feel like. Don't you guys think it's weird for my spider gears to be ate up more than normal?

 

If the pinion bearing
is bad, yes it will eat up the spider gears

 

Sound like the diff ate itself to death.
