any NNBS guys had frame beaming?

i have an 08, and i have a nasty bounce goin on from about 45-60ish. i lifted my truck and immediately noticed it. i have pretty much covered all my bases trying to fix it. it happens quite often, mostly when i drive over terrible roads. here is the kicker:

when i let off the gas, or slow down through that speed range, it is at it's worst....it still happens when accelerating, but coasting or braking makes it worse.


has anybody had these issues with their truck and frame beaming??? mine is an ECLB if that matters.

well, i installed the bushings. it was very very easy. seemed to take about 50% of the hopping/vibration out of my truck at 40-60

Have been fighting this for years on my truck. Cab mounts helped but is still there. Will come and go for me. Be more noticeable for a few months and bearable for a few months or maybe I'm just used to it. Definantly is not there when towing though. Good luck!

worm, they are new rear cab mounts. google search the term "frame beaming" and you will see a ton of info on it.

Curing vibrations is what I do for a living. Kinda funny I can't get it done on my own truck. Don't remember feeling mine when it was stock but I lifted at 2500 miles too. I have tried all sorts of stuff, from rotated hubs side to side to custom machined hub rings. Nothing has worked. May try sulastics but I am skeptical.

So the LMM's don't have the updated rear cab mounts? Seems like they would have figured this out by now...did you just use a jack and some wood to lift the rear of the cab? I need to get this done.

i have the same issues. vibration at 45-55 mph and HORRIBLE bouncing all over the place when i hit a bump at almost any speed.

all i have done is balance tires and replace old shocks.

i have the cab mounts and will finally put them on this weekend i think
