I've Found The Fix!

[davo32683]

This is to the leaf spring slap and squeaking from the rear end. In an attempt to avoid the GM ones (since those too would likely fall out like the factory ones) I went to Energy Suspension for their low profile bump stops.

 

Popped those in my empty holes on the bottom leaf this afternoon and went cruising down the road and not a noise! Nothing!

 

It was absolutely fantastic. I thought part of my problem was the slip yoke, but apparently it wasn't. The rear of my truck is normal now!

 

If anybody else is wanting some, go to www.energysuspensionparts.com and search in the top right for 99132G. You'll need 4, so 2 orders does it.

 

They bolt in, so they should be in there for a looooong time. If anybody needs any input or help on an install just let me know.

My truck has the leaf spring slap, makes a lot of noise, but i rubber undercoat the metal pads so it stops it for a little while. The rubber wore off mine originally which caused the noise. My fathers duramax has rubber pads on his leaf bump stop and doesnt make a hint of noise.

Try this fix for yours. They're poly and graphite impregnated, so I'm sure they'll last a while. Plus they're bolted in, so they aren't just falling off while riding down the road.

Can you gives us pics and explain how and where ?

Yep, I can do that, but I'll have to post Monday. I'm heading out of town in the morning and won't have access again until then.

 

Very easy to do though. Just jacked the rear up (front wheels chocked of course) under the diff. Removed rear tires. Placed a jack stand on each side of the frame as far back as possible while still being on a straight surface.

 

I then lowered the diff down to flex the springs out since the frame is sitting on the jack stands further up. This allowed the bumpstops w/bolts to go in easily with no prying apart leaves.

 

Just tightened them up and dropped the truck back down after putting the tires back on.

Here's some pics! The white stuff is lithium grease spray residue. Tried that first without much luck. The holes that the bolts go through are already there, so no drilling or anything needed. I added the washer separately as the nut was close to going through the hole. It was a 3/8" stainless washer. Nylon lock nut included with the bump stops.

Nice!

That is very creative. Maybe you should offer your services to GM to help them with those minor details that seem to get overlooked. Good Job!!!

[Norseman]

O'ya maybe you should post that in the how to section.

I have something simular to that on my 01 LS ext Cab from the factory

wait a minute here, is this what i'm hearing on mine?? I thought it was the rear drive shaft u joints? Every time i step on the throttle I hear a little bang, my buddies truck does the same?

[davo32683]

very likely that this is part of it.

[99silverado1500]

bang bump clunk is the slip joke, a slap or a clank is the bump stop. Rubber undercoating does work, but for a limited time only, as I did a lousy prep job aka none at all.

EXCELLENT find! Thank you VERY much for posting! This has been a recent problem with my Silverado.

 

Thanks again!
