Rear Axle Problems

I have a feeling that my bearings in my rear axles are bad, as i ride down the road my tires wobble from left to right (side to side) and i can feel the rear end of my car start to slip out from underneath me. is there anyone that has done this before and offer any advice?? I plan on getting new bearings and seals either tuesday or friday.

Thanks
 
The bearings aren't going to cause and slop side to side. At the same time, if the axles are actually moving, that means the c clips are gone or fallen out, which is very very unlikely. I had the same type of problem you are explaining, and it turned out to be one of the upper control arm bolts came out and the rear end would move around a LOT. Def not safe, but it's def not the axle bearings.
 
I bet the axles are just worn out jack the car up a bit and check for play side to side in the axles that will tell you right there. My Gf's 4 cyl 89 has like an inch of play in either axle (not safe at all buying new car for more reasons than just that).
Might be time for that 5 lug strange 31 spline swap you always wanted.


Question though... You did upgrade to an 8.8 right??? If not that's probably your issue right there.

There is a Posi 8.8 rearend under the car, thinking of staying with the 4-lug set-up, not many mustangs left with four lugs. if new axles are neded, could i go to 31 spline 4 lug axles or would i have to change out the gears too?

A couple of things. First there are way more 4 lug Foxes out there than there are 5 lug conversion Foxes.

Second thing... I want you to go to the back of your car and push it from the side repeatedly. Do you hear a semi-loud clunk everytime it moves that sounds like it's coming from the wheel? If so then you need to rebuild the traction lok. As the clutches wear it makes more room for the C clips to move back and forth. In extreme cases the c clips have been known to fall out.
