1992 C1500 Polyurethane A-arm Bushings Direction

[Leonidman63]

I'm installing the above Prothane kit and wondered if someone will tell me which way is the flange is supposed to go or if it matters. Should the flange go to the front or rear?
I can't find an answer on the net and the manufacturer was no help at all, the customer service rep referred to install instructions and a blog [which I've already have or read].

it should go in the same orientation as the bushing you took out. If you think of the bushing as a "T", then the top of the "T" will each be pointing towards the outsides of the upper arm.

Thank you, that's what I was wanting to know.

LOOK at the original bushing shells. The Poly inserts will be molded with the same steps. They can't be installed backwards.




Your C1500 is different. On my K1500:

Both ends of the upper bushings are covered by metal caps on the upper arms. The installer will have to save the metal caps, and re-use the inner sleeves from the old bushings. The lower bushings have no end-caps, and the inner sleeves are supplied with the bushing inserts. No idea why they don't supply new inner sleeves for the upper arm bushings.

My inner sleeves were so corroded, I had to fabricate new ones from steel tubing cut down so the OD was the same as the originals.
