First, make sure that nothing is binding on the front suspension. Check the fluid in the reservoir an make sure that it isn't foamy. You can adjust the "firmness" of your steering. looking down onto the top of your steering box, you will see a screw that has a lock nut on it. If you loosen the lock nut and then loosen the screw, you can check to see the binding is in the steering gear box by loosening this screw...but don't make it too loose or it will leak power steering fluid. Try these things and see if they get you anywhere.

It causes a pulling effects as the steering alternately gets harder and easier as you turn the wheel. The power steering pump doesn't make any noise or other wise show signs of a problem. How should I trouble shoot this? Michael Hissom aurea mediocritas P.S yes this is the same Cherokee with all the other problems, I'm just trying to slowly fix all the problems it has one at a time.

You look at the pulley to see if it's got rubber separating and if it's out of alignment... I'm not sure how this would cause the steering to be sporadic, but something to check on anyway. Usually the symptoms, if I recall correctly, are excessive engine vibration. john ----- - ------------------------------------------------------------------------ Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 http://creationwiki.org http://johnmeister.com http://wagoneers.com http://fotomeister.us - ------------------------------------------------------------------------ On Thu, 26 Mar 2009, Moontanman-at-aol.com wrote: # In a message dated 3/26/2009 12:22:52 P.M.

I don't need anymore problems for sure. The transmission does seem to be shifting less than smoothly but something that expensive will have to wait. This truck is a project for sure. One of those "if I had known I wouldn't have bought it" no doubt. At least some of the problems, I think, come from the less than expert lift kit that is on it. It rides rough if nothing else. I am thinking of taking the lift kit off but I'm not sure if it would make any real difference in the future reliability of the truck.

If it's not kicking down at all, it suggests this is either a faulty solenoid, valve body, or an electric control problem.

Are you sure that it's a "kick down" that you are looking for? My Jeep had a problem in that it was not able to get out of torque converter lockup. Once it hit 3rd gear, it went into torque converter lockup and stayed there no matter what, it wouldn't down-shift properly and when it did, it was very clunky...almost like a manual. It would shift into the lower gear but the engine would rev and slow the vehicle down, just like it would in a manual. I found the problem to be the brake pedal. Yup, the actual pedal inside the vehicle. Turns out that there's a switch there (two actually, the other one is for the brake lights). This switch is depressed when the brake pedal is not pushed. The switch is released when you push on the brake. This tells the torque converter to get out of lock. You can try an experiment on your own by driving down the road and when you hit a slight incline, while still giving the Jeep gas, tap the brake pedal. You will see the engine rev higher as the torque converter is released and as an added benefit you will get more power to scale that incline (all my 4.0L Jeeps suck at climbing hills at highway speeds...this gives the jeep a little extra boost) In my case, the metal bracket that the switch was mounted on was slightly bent. I straightened this and adjusted the switch and now the Jeep shifts properly in normal and performance mode once again!
