How do you align the steering gear of a Jeep Grand Cherokee?

Answer 1

If its Rac & Pinion count the total number of turns then bring it back to one half that number IF it has a Pitman arm-The arm should be pointing straight - inline with the vehicle.

That is how you center the rack& pinion steering gear,it does take more to adjust toe,which is the fastest tire wearing factor,on any vehicle. That is all the adjustment without aftermarket parts{more money}on 4wd vehicles,and this applies to 2wd vehicles,also. The maker of the vehicle only allows so many adjustments to be made without additional parts.All vehicles require additional parts to make needed adjustments to correctly align their product,so the option is to buy tires more often,if you don't want to do it right the first time.

The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
