Truck jumps right when accelerating over Bridges on highway

Lighting is poor but I viewed it big screen this time

Steering rack bushings and or inner tie rods
If wheel dont move up n down, the bearing may be ok if not rough feeling. They should be smooth as glass

 

Hey again!

What would a bad cab mount look like/feel like? I'm thinking this could still be why the truck bucks

I have and am about to install: new LCAs, wheel bearings, and new spindles (my divers side spindle was minorly bent from previous owners relatively minor front collision was likely the culprit of my alignment issues)

Thanks!

 

not a cab mount issue, my frame at the mount was rotted so much it would no longer hold alignment and did some wonky things over bumps
