anyone else notice this?

[smykowski]

Driving at highway speeds, we'll call it 65-70mph....on certain sections of the road which may be uneven or have slight dips in it, the back of my truck hops up and down like crazy. new shocks, new tires...so im 99% sure it's not that, but my god it's irritating. is it just a combination of the number of leafs in the springs on the back combined with an empy bed or what? I can see the back moving up and down in the mirror, but I've followed other rams on this stretch of road and i don't see it happening to them.

It's very hard to explain what happens but it bounces the hell outta everyone in the cab. I've seen others refer to it as the freeway bounce....and yes, this section of road happens to be concrete. Here's a quote from another person on another forum.

"I love everything about my truck but I hate to drive it to work. I live in L.A. and drive ona concrete, sectional freeway everyday (which seems to be the worst case scenario for this problem). At 65-75 mph, the vibration is enough to rattle your teeth out at times. "

any advice would be appreciated.

the only problem i ever noticed with the rear on my 05 was going through a curve and hit a bump in the road and the ass would skate out. Scares the **** out of you.

 

[smykowski]

yeah, it did that about 2 weeks ago when the road was wet, damn near spun around in middle of a 2 lane highway...not fun.

ok ignore the doucher in the tundra or the fact this is an advertisement...sorry mods! but this is exactly what happens. Bouncing Baby Head - The Willybar - YouTube

I've experienced what Butch mentioned but not the other things.

Mine does it everynow and then on a bumpy curve, but I think youre talkin about road wobble... maybe you could try a rear sway bar?

Well look what the cat dun drug in ... Where the hell have you been boy !

Bring her up to the house we will hook it up .

But try this ... can you (being a big ol boy ) push down on the tail gate and easily make the ass end sink ?

 

[05singlecabHEMI]

Happens in my truck too. It doesnt bother me. My guess is cause the suspension is really stiff it doesnt absorb the dips in the road so you feel it. Thats just my opinion on it.

 

[ramhunter9]

That ***** bar is just some plated metal LOL...

Go get some sand bags and that should work

 

[quietpeen]

i was gonna say try a helwig sway bar. JJ had one on his 08 and said it helped with the rear end

^^^ thats what i was going to say

That'd have to be a big ass cat...maybe the dog drug me in lol. Been working non stop since our gtg at your place.....seems like June was just last week!

I can't make the rear drop at all, since i put new shocks on all four corners, it's pretty solid.

Oh and what is that in your sig!?!! I wouldn't say I "regret" buying my truck, but my neighbor has 2 CTD's and he's a tech at a diesel performance shop..I'd be lying if I said I wasn't jealous at times.


I might try some weight in the back and see what that does....anyone have scrap steel laying around? or plates..im not picky

OMG the helwig sway bars are awesome! I have one and its the best mod ive done to the truck suspension wise.

 

[bigbadram1500]

Maybe I should get one of those. Already practically rebuilt the front end, might as well start beefing up the rear lol I do remember JJ saying that bar really helped out.

 

[rambob]

mine does it empty. not on the highway or curves though, at slower speeds. 40 mph
I just thought it was b/c of the lift blocks.
my z71 did it as well, had an add a leaf lift.

I'm sure its just the stiffness of the leaf springs. as stated, a few sand bags should help.
or maybe some air ride shocks or helper bags, if they still make those.

You got any lifting weights laying around ? Put them in there ...

But if your new shocks are to stiff that could be the problem causing wheel hop not so much flex

helwig for the win!

not sure it will help up and down vibration though.

That sucks..couldn't image it happening on a slick patch

There is a spot on I75 north of Dayton where my dad's 2500 long bed feels like it is coming apart.

Change lanes no problem. Go back to the slow lane, it feels like you are on a bad carnival ride.

Same place in my brother's 2500 reg bed and you can only barely feel the road vibrations.
