Re: Bump steer problem. Need advice from a dually Guru.
I had the level kit for years. Until I got the 19.5s and 35.4" nitto ( m-608z) on and off road big rig tires, that's when the truck started it's problem. Got the alignment, did the dual stabilizers, new shocks. It got better after that but was still doing that awful sway. It use to vibrate over 65 before the alignment. After the alignment, it just did that rear end dually sway.
I have hellwig sway bars for the front and back. The front ones are 2.5 inches longer for the level kit. They aren't on yet.
And I have a drop track bar bracket. And I have the drop radius arm brackets. Which should change the caster. I'm just not sure which one is going to help and make it better? Or which one make it worse? Or will they not do anything??? I don't want to screw up and do the wrong one first ... Then have days and days to figure it out.
FYI I don't have steer tires in the front either. I'm not sure if I need these because it's a dually. They do it on big rigs. I just don't want to make the tread look different . I also got my tires true aligned. Where they shear the tires on a machine that gets them up to speed and cuts them to the curvature of the road. When they did the alignment they fixed all the seals that were out also.
The truck runs fine on good solid flat road . If it hits a little dip or rough spot in the road the whole
Truck shifts in the rear. It just has to be the smallest little bump or rough spot. It can just be the shoulder being a little rocky and throw me off. Especially if I'm tring to slow down on the shoulder and turn, it gets even worse. Than if I'm just driving straight and not slowing down.
