Anybody know if there different? I have what looks to be a 5 rear and I need to switch out some arms. They all look the same but only the A-arms are aluminum.


Also for those that might have slid into curbing on the track what is the weak link? Can't find anything bent but got a whole bunch of toe in and positive camber. Impact hard enough to bend both rims. I've pulled the toe link off and it's the same as the other side. Going to change out the trailing link.

 

Toe in and positive camber would tell me you lower arm is bent.

 

Thanks for the reply. I thought that too. I've measured them and put a straight edge on both of them. I haven't had time to take them off the car yet. I'm taking each arm off, building a jig for it and then compare to the other side and the 5 rear end. So far the trailing arm and the toe link are straight. Those two being straight and in front of the axle would lead me to think that if the lower arm was bent it wouldn't give me toe in since it's behind the axle. I'm taking everything completely apart. Might as well with 140K on the car. I'll replace all the bushings with Whiteline stuff. Here might be the problem. After I have everything off I'll re-align the crossmember. Just can't see the crossmember moving without some of the aluminum arms being bent.

 

The geometry is the same.
Only difference is what you have noticed with the arms being steel apart from the upper arm.

 

Thanks.
