suspension/ handling trouble

OK, here it is. Bought a 96 grand Cherokee lorado for my son. Turning 16 in July. The handling on it was terrible, had the front end parts looked at and nothing is new, but all looks good. 3 different shops. put in a new gear box and an alignment and the handling got a lot better. But it seems to still have some pull on uneven roads and sometimes it feels like some body roll when going down the road. Also seems like some of the body roll is in the back end. What could be wrong in the back?
That said, do I take it in and let someone put it to me and fix it or do I just start throwing money into it till its new again?

What would you suggest replacing to fix this. Shocks? springs? track bar? All front end parts look good Im told.

If its shocks you are going to suggest please point me in the right direction for type. Kolac (SP) I am sure will ship me what I need.

Some Addco sway bars and bushings should help.

Body roll

Did they check the track bar in the back? What kind of tires and pressure?

New control arms , or just bushings . Done them on every jeep I bought yet . Sway bar frame bushings really help too . Adcco makes a nice upgrade . I have used the rear and loved it .

I did not see them check the rear. I will check tire pressure.
Sway bar. would you suggest changing both front and back or one or the other?

Does anyone suggest front or rear? I have play in one of the front ones. It is sliding on the lower point. thinking of trying just that one and see if it helps. I would be willing to do one of them with the upgraded Addco, but both at once is a little pricey.

After I put on new shocks and a front addco I still had considerable body roll. I replaced the control arm bushings and now it rides like new.

Yeah if you've got play in your control arm bushings, then it's probably time to change the bushings or both. I just did my lower front control arms, and found its almost just as cheap to replace the whole arm w/bushings than just the bushings, and a whole lot easier.

You might also want to get new bolts for it, as I've seen a lot of guys strip or break their bolts trying to get them off, or just cutting them off. I myself broke two socket wrenches getting mine off, but didn't break the bolts.

The front lowers require two special cam bolts on the fore ends, and the backs require either OEM bolts from the dealer or grade 10.9 size M14x2.0x100 bolts you can get from Fastenal, and for those you'll have to get washers too.

If you chock the fronts and backs of your wheels or put a cinder block on your brake pedal you won't even have to jack it up as long as you replace the arms one at a time.

Oh yeah, and I ordered my new Moog arms from rock auto for about 30 bucks each, cam bolts were 20 for the set, reg bolts were about 6 each. Took a couple hours. The two socket wrenches I broke were craftsman so no cost for replacement. :-)

The shop wanted to charge me 700 dollars!

Shocks and springs. Probly soft saggy springs coupled with worn shocks as well as all that was said above.I would never expect to have a tight steering box because I've yet to meet anyone who without extensive upgrading has a ZJ with a tight steering box.

I'm very interested to find out if you ever get a good solution. The 5.9 I bought for my son has a lot of roll in it and it seemed like it was coming from the rear. I replaced the rear wheel bearings and the rear track bar and that made it considerably better. Unfortunately I did them at the same time, so I don't know which one of those accounted for the butt waggle.

No one would have bought one of these things off the showroom floor if they handled like this from the start. Right now, it's acceptable, but really would like to get it back to like new condition.

Hoping to hear more success stories from anyone replacing front control arms (or shocks or sway bar ends, whatever). It's a little freaky changing lanes sometimes if the lanes aren't perfectly even.

sounds like we have the same ZJ. I found the front lower sway bar bolt was sliding up and down in the mount. Replaced it and it helped a little of the body roll and a lot of the steering pull. I want to do the upgrade rear sway bar and thinking control arms to help both problems. Gear box helped a bunch for sure, it was real bad before that.
