the bounce

I have an 06 4X4 2500 and also live in Thousand Oaks...I brought my truck in for the allison trans service and when I picked it up the service tech actually brought it to my attention that they had replaced the mounts for me(for free). The truck rides 100% better. Take it to William L. Morris Chevy in Simi Valley

Interesting. Anyone know what the difference is between 25791031 and 25994881? GMPD lists both, but 25994881 is ~ $5 more expensive...

When I ordered mine I was told that 25994881 replaced 25791031.

I have the original 25791031's on mine, but it could be that the 25994881's don't make as much of a klinking noise when entering and exiting driveways.

I noticed those extra sounds immediately after installation. Was happy to trade those little noises for the tremendously improved ride. You don't notice them once driving down the road.

Can anyone confirm the improvements of the 25994881's? Less operational noise on driveway entrance/exit??

If so, I'll just have to order a pair of 25994881's soon....

Dealer refused to reset mine. I got new tires and had the tire shop yank 'em out. The light stays on and service TPMS comes up on the display but is easily cleared. Slightly better than clearing TPMS warnings for all four tires.

Later I heard of a better trick. Yank 'em out and put them in a a piece of PVC pipe. Cap both ends and put a valve stem in one end. Seal them up in there and air it up to 65-70 psi. Throw it under the back seat and the TPMS will no longer bother you. Unfortunately, my sensors were long gone before that idea surfaced.

TPMS is just another government mandated POS. Remember Obama claiming we could save millions of gallons of gas by airing up our tires?

Serious this would still be covered under warranty??? Ive read about this but am waiting to update them due to it not being a real neccessity as its not hurting anything on the truck. My dealer is a POS but should this still be covered even though its an 06' and its 2010???

I love these government mandated ideas, they are great aren't they?

Does the PVC trick work for sure? I read that idea not too long ago and was wondering if I should have tried it.

It's covered under the 3 yr/36K mile warranty.

I finally got around to changing my mounts yesterday. Not as bad as I thought, but after removing the rear most cab bolts and loosening the other 4(2 on each side), I tried to jack up the cab as was suggested using a jack with 14 inch 2x4 in the center of the cab where there is a support bracket, but it started to lift the whole truck. I used the 2x4 more towards the side of the cab close to the actual cab mount to get it to start separating and then after moved the 2x4 back to the center of the cab where I initially started to jack it up and that helped.

All said it took about 45 min total time. I torqued them all down to the 56ftlbs as suggested, but got some popping in the front when going up my driveway so I increased just the front 4 to 60ftlbs but when I came home last night it popped again so today I torqued them down to 70. We'll see. The rears I left at 56 because that little doughnut got compressed pretty good.

The ride is better, I won't say 100% or even 50%. To me 100% would be closer to an Escalade ride, 50% would be how an HD truck should ride so I'd give it just under 50%. It basically takes most of the harshness out. I think the springs come into play a lot in these truck and they should design a better leaf pack, but it was worth the money spent on the new mounts.

Oh yeah, there is the new PN 25994881, old one is discontinued.
