"squeaky" leaf springs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*Shane* · 06-12-2011, 07:04 PM

Got an issue that I've not run across before, the leaf springs on my '05 GMC have started "squeaking" as of late. Tried experimenting with a bit of white lithium grease on the spring mounts/shackles with very little luck. I've owned at least 5 trucks with leafs in the rear and this is the first time I've had this issue. I'm scratching my head.

advice? thoughts? suggestions?

My 98 used to do that on the front and rear suspension components. I used a liberal amount of white lithium on all of the rubber stuff and it would take a few days to work into the parts, then it would last a month or so. I drive down a lot of white rock roads though, so it kinda comes with the territory.

Are they stock bushing? You know the problems associated with urethane bushings, but I have not heard of this with stockers.

they are stock on the front hanger and McGaughey's shackles in the rear - unsure what they put in their shackles ... but the weird part is the squeaking seems to be coming from BOTH ends.

I'll bet the McGaughys are urethane. Sounds like your going to need some Polyurethane lube
