So lately my car has been doing funky things. It only happens taking off but what it is, is it feel like the rear suspension is getting bound up and then just popping loose.

The feeling of it feel like its raising the back of the car and then popping back down. Sometimes it makes a noise sometimes it doesnt.
Best way to kind of desrcibe it is it has the feeling of a broken motor mount, the motor twists let of and clunk.

Ive been thinking its my tranny but im not sure. Any thoughts, or do I need to describe better?

Oh yeah, I have after market uppers and lowers for the rear also, same with springs and shocks.

Are they polyurithane bushings? I hear that sometimes they have a tendancy to bind up.

Mikey, your car is ruined. There is no way to fix this problem, and i suggest you just give me that pile of junk.



But seriously. I really dont know what it could be. I had bad shocks and that gave me a funny wheel hop, but i think your problem is different.

Uppers are Steeda HD with Poly on the chassis side and rubber on the axle side.
Lowers are Granetelli weight jackers with Poly axle side and spherical chassis side.

I just wondering if I should change out my little pinion snubber rubber thing since Eibach gave me one to swap with stock when I got my springs. That is kind of what it feels like though, that the axle rotates, get bound up right before its supposed to and kinda gives up.

I thought it could be my trans too, I have never had a manual trans go out on me and I dont know what it feels like yet.

how much power are you making fox bodies are know for making axel torque that is were the rear end twist and lifts the right rear wheel of the ground

Yeah about those, bought some tq box reinforcers in December....ummm they're still all wrapped up in plastic. Maybe thats a good idea for this weekend. Subframes, still havent got around to it. I know I need em, Im twisting this car to sh*&. After I put in this engine I have so many new rattles, just taking off "normally" the dash just creeks and cracks, horrible twistage going on!

Would that cause it to bind up though? Or give it that feeling?

Now I can only really notice it when Im taking off like a sane person. If I just hammer it, it just goes, it might still be binding up and I just cant notice though.

i would try the torgue boxes first the only thing i found that fixes axle tq is a anti rool bar
