Help with aluminum dif. bushings.

[Since 1964]

I tried to have the aluminum bushing installed on my car today. After they were in. the the bolts for the control arms would not match up. The Kenney brown forward torque brace is so bent up that it would not line up with the control arms. The mechaninc said if he forces it my differential will be twisted and under pressure all the time.

I think the forward torque brace is bent and we will try the factory one tomorrow to confirm.

Has any one else noticed this?

Hes right, im studying trans and differentials right now and we just kinda went over that

must be a bent support or something. the KB bushings fit much easier than brand N or the MM poly bushings (which will melt in short order) but they get the pinion angle wrong. be sure to stack a few more big washers to get the pinion angle where you want it.

I used mm aluminum and had no problems. Although I am w/ the factory 03/04 forward brace. I would have thought you would leave the forward brace in place and then added shims above and below. Why was the forward brace taken out? Is the forward brace a new install?



Here is where I was @ before I checked the pinion angle. The resultant pinion andgl was off .35 degrees. I then moved one thin shim from the bottom and put it on the top. Each thin shim (In the mm kit) changes the pinion angle approx .25 degree. My resultant pinion angle is only off .1 degree +/- .1 degree since se are near the resolution of the digital gauge that I use.

That bottom stack of silver washers/shims is actually about 5 ~ 6 shims.

Thanks Vince. I'm taking the picture with me to the shop and trying to figure it out.
