I've been battleing front suspension and steering probelms on my 03 4X4 TRD O/R for the better part of two years now. The truck has a nasty case of bump steer. The slightest bump will cause this truck to almost change lanes. The truck also wanders all over the road.
I've replaced the shocks all around with 5100's. The fronts are set to the middle slot so she's got about 1.5 inches of lift in the front. I replaced the Steering rack bushing along with the Sway bar bushing while I was under there.
It running a year old set of Revo's set to 34 psi front 32 psi rear. Tires are like new with no signs of wear.
My truck also suffers from the loose steering shaft so i'm taking that out to be welded together this coming weekend.
I had the truck aligned after the front end work was done but looking at the sheet it appears that they didn't do any caster adjustments as that section of the sheet is blank.
I've been told that caster is the adjustment that controls bump steer. The more caster the truck has the better it will track. IS this true? Could a lack of Caster be the problem?
