The rear bounces, I should say.

Whats going on?

No weight in the back and the LSD kicking in?

Does yours do this?

When I try to feather the throttle to see if I can get out without being in 4WD, it will bounce (If I'm stuck)

Whats the deal-e-o?

 

sounds like wheel hop to me, I would put some weight in the back and maybe invest in some traction bars to eliminate the problem

Lighter foot might help too depending on the exact situation.

 

need some traction bars. its twisting the leaf springs resulting in the wheel hop. you could either bury your foot further or get off of it more. either one will work. and yes mine does this too cuz i dont have traction bars

This is normal. The tires are getting better traction, then loosing traction. This results in the leaf springs allowing the axle to twist under the truck, then untwist, then twist, etc. If this is a really big problem, you could get traction bars but it isn't that big of a deal to live with in most situations.

 

the problem with wheel hop, is it shockloads the driveline, and can cause the driveshaft to be spit out. it must be pretty severe hop though, but it isnt good.

 

Thanks as always, guys!

 

Try replacing the shocks Mine would do the same thing....new shocks and problem gone!!

 

If you use 4wd often, I would deal with it. Getting traction bars or ladder bars will help. The above posts are correct, axle wrap is the problem. Shop hard, the bars are not all equal in that they can really make your rear suspension way too stiff or be noisy. Changing shocks did not help me, or changing their stiffness, as I can do that in the cab. Lowering tire pressure will help, but that is not always a good thing to do unless you have a way to fill them back up. Flooring it can do more harm than not, as I have smacked my radiator with my fan resulting in a two day field repair and a new radiator when I got home, something I rather not do again. I have a lot of respect for the damage that wheel hop can do, so again, if you use 4wd, deal with it. Do a search on ladder bars or wheel hop, a lot has been written about it.
