rear end bounce

[ERMiles]

I just replaced my big 33x12. 5x16. 5 wheels and tires with 16" alloy wheels and Dunlops partially to eliminate an annoying bounce I get at 35-40 mph and again at 60-70mph. It's still there. I have checked the E brake cables twice thinking that they are dragging and re-balanced the rear wheels to no avail. It feels like the right rear wheel is bouncing almost like it's out of round. I'm about to haul our horses to Virginia next week and really want to get rid of this problem - it's not quite as bad with the weight of the gooseneck.

Is it possible that this is a bearing problem or, worse, differential - I hope not - I've already spent a ton of $$$ on the wheels, brakes, fan belt, etc. , etc. !

Shocks?

You didn't mention shocks. That would be where I would start. Good luck.

I haven't replaced the shocks - dunno how old they are. The springs are so stiff that I can't tell if they are good or bad.

What would you recommend for a good basic shock?

It could be something in the driveline that isn't balanced or even a universal. May want to check transmission mounts also.

I know what you mean about stiff springs, but that's what makes our trucks real trucks that can haul a load. Pull the bolt from one end of each shock and see if there is any resistance left when you push/pull them.



As far as brands, I have had good luck with Skyjacker Hydros. There have been several posts on this board about Rancho 9000's being good, but I have no experience with them. They are expensive, but adjustable.



Good luck
