Like most of the trucks, the rear leaf spring slap pads
disintegrated on my truck. They were gone in a few
thousand miles. I spent some time with GM yesterday
and checked out the problem. New parts have been
made and there is a TSB on the issue, but the dealer
would not pay for me to try the new parts. But I checked
the new parts at the parts counter, and they are the same
easy-crack plastic as the originals.

So I contacted Energy Suspensions and have ordered the 9.9132
bumpers. I will try these and report back if they are viable
replacements for the stock parts. There is a chance I can
get a run of direct replacement parts made up in urethane for
those of you tired of the stock spring slap.

You can also get them from Merchant Auto

What was the cost?

$8.99 at the local off-road shop

Finally I got a few minutes to try this out.
The mod is EASY. 10 minutes for all 4.

Just get 4 stainless washers to make the fit a bit better.

1) take all the parts out of the boxes
2) jack up front spring perch
3) use a screwdriver to unload the spring just a bit
4) pop in the new piece
5) add washer and tighten nut
6) repeat for the other 3 positions.

Cheap, easy, fast, effective.

Put this one in the DIY list?

Mine are making a really loud slap, even when going around like an incline when turning, but non of the pads seem to be worn out. I dont know what to do, its driving me crazy.

Might want to check out the threads on greasing the yoke on the driveshaft. I believe these two sounds could be mistaken for one another.

Frank_EP thanks for the info. I'm also tired of listening to my noisy springs. I'm going to order 2 pair of the bumpstops as soon as possible.
