Title: Pre 88 front suspension upper a-arm pivot bolt mount loose!
Post by: f85gtron on March 06, 2017, 09:57:06 am

On my 85, the upper a-arm pivot bolt sheath is loose. With it loose, it allows caster to move a few degrees forward and aft.  I don't notice it while driving, but it needs to be fixed.  Obviously, I need to weld it, but how best to do it and in what position is best?  Caster angles are what for pre 88?

I had the identical problem when I had my 84 convertible, although it probably wasn't bad enough to hose the alignment.
I had thought about drilling and sleeving that tube. Ended up selling the car before I did anything with it.

Apparently the 88 rear knuckles had a similar issue. The "long bolt" would wiggle around in the hole, messing up the alignment.
Rodney Dickman came up with a clamp/girdle affair that stopped the bolt from moving around. You might be able to fabricate something like that.
