Shackle Squeak? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys,

This last weekend I replaced the bushings in my leafsprings with some stock rubber ones. Well there was no squeak at all, last night I was showing someone and it started squeaking really really loud. I got under the truck and it seems to be coming from the shackle, when I loosen up that bolt the squeak takes longer to notice (pushing up and down on the truck).

The shackle has a uthrane type bushing not 100% sure. Is it possible, thats the problem and I should replace that one with rubber ones as well?

did you use the lube that came with them?

Urethane is going to squeak. You can lube it to make it quite for a while but it will squeak.

I would replace it with a rubber or polygraphite bushing.

I didnt put the drop shackles on, that was done by the PO so I dont have the lube for them.

I will swap them out this weekend and see if it goes away

The black poly bushings have graphite in them... the red one's don't (so i've heard)

Um, my friend asked me what kind of grease I used for everything, I just went out into the garage....

How bad is wheel bearing grease on rubber? I thought I had swapped the wheel bearing grease out of my gun and put suspension grease in it... I didnt...

Do I need to take the truck apart again this weekend and wipe all the wheel bearing grease off and use suspension grease?

I used the wheel bearing grease to slide the new bushings in and just put it on the outside of the bushing to slide them into the mounts...

is it petroleum based vs silcone based? That's the only issue I see, petro might eat through the poly. I'd google it though.

I just went out and looked at the grease, It says Multi purpose wheel bearing grease and HD chassis grease. It is white lithium based grease, I think I will be alright. If not the bushings were only 40$s so I can buy more if it eats everything away dont really want to take apart the suspension again..
