Lower it.

Heavy vehicle, high center of gravity, normal operation. You can find a source for larger sway bars and modify them to work. But that will probably just give a false sense of control since there will be less body roll. Solid axles aren't the best for handling by any means.

As long as its normal. Will all lifts feel this way?

Can you elaborate on "Turn the wheel from side to side"?

How fast are you moving (5 KMPH, 50 KMPH 150 KMPH)?

How much do turn the wheel (5 deg, 90 deg, 360 deg)?

Also, how high is your effective lift and what extra gear have you installed?

You can make any vehicle other than a go cart, locomotive or D9 CAT sway side to side under the right conditions.

It is not just dependent the high of the vehicle and its CG. It depends on the relationship of the Roll Center (or more properly the Roll Axis) and the CG.

Sounds like wandering steering. Do you have to adjust your steering wheel often to stay in a straight line?


From what I hear on these forums, the best fix for this is to get an alignment and fix your caster. Just wait for some feedback from other members.

I wouldn't know this stuff. *laughs* I just mentioned what I view as a popular topic on these forums.

Best to wait for the "professional" people to come on here.

You need a prescription for more castor, get some adjustable arms.
