ok, ive got my 1982 chevy 3500 crew cab dually i have been working on, 12 valve cummins, 10 speed fuller with married transfer case, custom front suspension and a whole lot more. ive got a question on the front suspension. there isnt really anything wrong per say, just odd. my truck was 2wd so i started from scratch with the whole front end, i custom made a k member complete with coil spring buckets. i ran a 2004 ford superduty axle because i got a steal on it. i converted it to coil springs, and custom made my own 3 link with panhard bar. the axle has a high steer arm, and custom draglink, and panhard bar. im running factory 08+ superduty coils and the factory 2wd shocks from my truck. all components are brand spanking new, ive run the truck down the road a few times, rough country backroads with lots of potholes, i have no bump steer or death wobble. what my problem is, when the truck is sitting still, if i turn the wheel to the left or right the whole front suspension moves up and down. anyone got an idea on what might cause that? like i said the truck rides like a cadillac, but the whole suspension decompressing while steering at a standstill has be stumped.
