Bump steer

I have bump steer when going over bumps. I have icon coil-overs with about 2.5" of lift and icon UCA's. I think an alignment will get rid of the bump steer. what do you guys think? what specs should I align it to?

 

Do a quick and easy check.

Where the tie rod ends attach, measure the amount of threads showing on both tie rods from the jam nuts along the rods inward toward the rack bellows to the point where the threaded part ends. The factory says they have to be equal with a variance of only 1 thread (1.5mm) difference between the RH and LH tie rods.

 

Low caster can cause bump steer, as well as tire pressure(which was my case when it was over-inflated)

 

what tire pressure do u run? i run 30-35

 

Tire pressure depends on many factors and everyone is different. Short answer is to do a chalk test and find out for yourself for your particular truck & tire combo.

I noticed a big difference going from 35psi to just 32psi. My E-rated tires are definitely a factor lol

 

Bump steer is caused by altered suspension (raising or lowering). Because the tie rods are now to short or to long and dont "follow" the same arc path as the tire/spindle anymore.
