Default Poly Bushing Installation

I was in the process of installing new poly bushings in my upper control arms last night when I ran into an issue. According to the directions the inner bushing sleeves should protrude about 0.01" past the outside edge of the bushing. The problem is when I position the inner bushing sleeves against the cross shaft shoulders the sleeves don't extend beyond the bushing. Am I missing something? Should I place a shim between the cross shaft shoulder and inner sleeve? The problem is exactly the same on both control arms so I don't think the problem is due to the arms being damaged. As allowe per the directions, I'm re-using the existing outer bushing sleeves - they appear to be in good condition.



Sleeve seated tightly agains cross shaft shoulder


If I position the cross shaft such that the sleeve is flush with the bushing on one one side...


I come up short on the other side...


Any ideas?

Take a belt sander to the outside of the bushings and get the clearance you are looking for. I clearanced all of mine about .005 to .010 going by a book I read. Some poeple and manufacturs say it is not needed but I clearance mine. The purpose of poly bushings is supposted to be to take away deflection in the ft. end and as in the article I read they should move easyily with no binding and as little clearance as possible. If they are clearanced properly it should take care of a lot of the squeaks and looseing bolts you hear so much about.

The control arms look great. Are they powder coated or painted?

It's not a matter of the sleeves being too long, they're too short! I think I may just use a piece of the old bushing inner sleeves as a spacer.


The control arms are painted, two coats of POR-15 and a top coat of Chassis black. Thanks!

When I said to take a belt sander to the outside of the bushing I ment to remove material from the end where the washer and bolt go. You will need to take the bushing out of the sleeves to do this.

Don't forget to use loctite on the bolts after the suspension settles. This is recommended for poly bushings.
