sway?

hopen u guys can help me out got a 96 crew cab on 22s semis tri. 4 link it was on 19s with diffent setup and had no problem but now we redid it for the 22s is got a rock from left to right at about 60 mph anny body have this befor anny in put would help!!!!!!!!


need help.

What type of 4 link setup are you running now? Parallel, Triangle, etc?

triangled 4 link with the bags on the upper link bars

Have you tried putting on some stocks or different wheels. Maybe your rims are out of balance....? Just a suggestion.

what size tubing are the upper bars? maybe the bars are flexing a little, causing the rear to move a little? just a thought. later, brian

what bout alignment or suspension components

i cant rember the tube size but ithe pinon angle is good and the alignment is good but my rear end dose not move just the cab and im able to contol it buy the trottle and its like in a boat sway in the rear

the weight of the truck, and the torque from the throttle on the upper bars is causing them to change the geometry of the bars some, resulting in the rear end actually moving forward slightlyon the side with the most pressure. when this happens, it will make the truck sway.

so what u think will fix this ???

either reinforce the bars under the bag, or take the bag off the upper bars completly. i was never a fan of having the bars on the upper bar. do you have any pics of it? later, brian
