Replacing Sway bar Bushings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Big69C20 Toy · 05-29-2002, 01:19 AM

Hey all i'm about to go buy some nice poly bushings and i measured my front bar 1 1/16 and the rear was 1 1/8. Do those sizes sound about right for a 3/4ton cst with a bb? I know the front sounds about right but i've no clue on the rear.
Also i was wondering what's the best way of going about this whole thing. The rear doesnt even seem to be tight or anything. Should i get a couple of shorter link bars (name?) for the rear if that is the case? The rear bar has it's D bushings held on by a bolt on each side of the trailing arm (2 bolts per arm) Seems like that's not enuf but then again it also seems liek the whole assembly isnt too tight.

Thanks all for the help,
Greg

I bought my sway bars from Early Classics Enterprise, I found them to be VERY KNOLAGEBLE on the subject. They sell a front bar that is much bigger and I think might be helpful with a big block! I think they can also help with the rear. good luck, sorry i'm not more help

Correct 67-72 3/4 ton front bars are all 1-1/16th.
Your rear bar is aftermarket. Can't help there.

Well thanks for the info guys, just wish there was a bit more out there on how to do it. Aww well i'll dive on in there and figure it out i guess, maybe call Early Classic too for some info....

The simplest and cheapest would probably be Summit. Just measure your bars then tell them how many of each you need. Should be 4 for the front and 2 for the back.

They're simple to replace. Just unbolt the bushing clamps and replace them.
