Chevy II bump steer

[ken robinson]

I'm not a front end guy afco sells a longer lower ball joint , what dose that change in the front end set up ? On my 67 camaro I'm seeing the top of my front tires tilting inward at the top wheel stand only they use to stay straight thru the full range of travel up and down . At ride its find its bine 5 years since Jack Arnew set it up .

A longer upper ball joint will help correct that problem.

Ken, let's look at it this way. The upper A arm is shorter than the lower. At full lift, the upper tucks in towards the sub frame, causing negative camber.
Let's say , looking that the right front suspension, the A arm is at 8:30 position. A longer ball joint would put it at 9:00, and the spindle won't be tucked in as far.
If your situation is getting worse, it could be that the snubber under the upper arm is collapsing, and that's the best news I can give you.

I just bring my 67/nova to an older gentleman alinement guy
He puts a couple of extra shims behind upper control arms
My cars Been working for over 30 years for me. Not rocket science

James, That's what I did to my 66 Nova years ago. A few shims and it was a whole different car. Probably made the biggest et improvement of anything else I did.
