steering TOO easy!!

Im running a heavy duty steering box on my 97' w a 4" lift and 35' s and there's a solid few inches of play in the wheel since I did the change from the stock box. I'm used to the wandering and such but this is almost comically bad. And does anyone's jeep turn TOO EASY? Is there such thing as heavier power steering fluid? Could I have air in the line? Is that possible? I would love to make it a little harder to turn. Any insite would be great, thanks

get an alignment. I'll bet good money your caster is 2-3°, maybe less. you're using the stock control arms aren't you? if not...fix your caster!

X2, my thoughts are that the caster angle is insufficient too. For 35" tires, 4.5 to 5 degrees of caster angle is about right.

get an alignment. see what your caster spec is now.

then adjust the uppers in all the way, and extend the lowers the necessary amount to get to 5-5.5 deg caster with 35s.

get another alignment to verify caster spec and reset toe-in.

toe-in changes when you change caster.

easy steering and not holding track,constantly needing corrections,more noticable on the highway.Way too much input needed to stay in your lane.Thats the way mine acted with too much negative castor.I took a reading with an angle gauge on the steering knuckle by the top ball joint.Used it for reference,then adjusted my upper control arms shorter,rechecked the angle finder to see 1.5 deg change.Then test rode it,much,much better!.I also checked the front driveshaft angle to make sure I wasnt changing the pinion to driveshaft angle too much..Still dont know what the exact castor is,but I can cruise the highway @ 80mph now without an anxiety attach LOL!

As mentioned above, the caster angle has a huge effect on steering and its stability. But toe-in has an effect too so, really, you need to verify that both the toe-in and caster angles are both where they should be.

Caution that an alignment shop may say they need to set your caster angle to 7 degrees which is the factory caster angle. That 7 degree factory caster angle is correct for stock size tires up to about 30" but for larger size tires, you need less caster angle 5-6 degrees is right for 33" tires but 4.5 to 5 degrees is right for 35" tires.
