Steering Box Options?

need to replace the steering box/gear on the 93, the sector shaft has all sorts of slop and she drives really bad on the road. have already replaced all of the control arms, track bars and steering linkage.

since it seems to hit n miss when buying a reman from the parts stores, im going to keep my eyes out for a unit from the bone yards from a lower mileage vehicle. will the units from XJs and TJs work? not really interested in the durango box

XJs work, but IIRC TJs at some point switched to a different box on the later years. IIRC also YJ power steering boxes should work too, but they're starting to be faily high mile/ old units.

I've had XJ pump in mine, it's got less reduction rate (thus, less steering wheel turns and harder to turn).
Watch out if you've got a speed-proportional pump, FSM says it doesn't go well together with non-proportional gear,
however I havent noticed any bad (mine's speed proportional).

If you get a JY steering gear, rebuild it if there is anything in question, its out and serviceable!!!

If you have speed proportional steering you can convert a non SP box easily by removing the spool valve out of the old box and installing it in the replacement box, or just replace the entire valve body assembly in to your replacement steering gear.

I doubt seriously you will have SPS on your 93 but the donor box might if its the only good one and out of a 96 through 98 jeep grand, but you will see the added electrical connection on the power steering pump if its still there?. and your spool valve will be slightly different in the steering gear.

Worse case is if your using a steering gear with SPS and you didn't change out the spool valve it will not act like the normal hydraulic assist you had before!

Yeah don't junk around with steering boxes. I put a new box with snow plow for a durango from napa in my '97. I love it. Go for the one without if you want the faster turn radius (I didn't want that). It bolted right up in my 97.
