Back end sways side to side
I have a 1999 jeep grand cherokee limited it sat in the garage for 4 years. The back end sways side to side I had the sway bar bushings replaced it stopped doing it for 2 days then started again. I'm thinking if it's the rear coil springs?

Check the lower control arm bushings. My 2000 WJ had that problem and on inspection, the outer case of the bushings on the axle ends had rusted thru. My advise is to buy new arms complete with bushings. 4 bolts and you're done. They save a lot of heartache.

Since my WJ had around 200K on it, I replaced all 7. The upper rear was the most expensive with the ball joint.

I had the rear upper control arm and ball joint replaced about a month ago and the rear Sway bar bushings replaced last week. My jeep has over 200 thousand miles had a new engine put in 2012. A mechanic checked the lower control arms he said they were good cause they didn't move but he didn't look closely at the bushings.

youd know better than us. Are they different tires just name brand. Are the sizes the same. Pressure. If it sat you could have developed flat spots but I don't think they would cause the issue. what about shocks. Are they new. I would probably go with what Dave said and replace some parts since hey have some age on them.

If you have Quadratrac, tire size and wear pattern is important to be matched on all 4 wheels. Selectrac is sensitive to the rear tires being matched, but once in 4wd, all bets are off. Different tires sizes, even different wear on the same brand/size tires will cause different drive shaft speeds and cause instability, or in extreme cases, binding of the t/case.
Case in point. I ruined the Positraction unit in my 67 Camaro by putting a compact spare on the rear and driving 50 miles at highway speeds. I should have put a front tire on it instead, but having a flat in the pouring rain at night, I just needed to get it off the highway. Driving that at 50 mph was squirrely at best!

Agree with above. Time to plunk down the cash for a new set of 5. (Don't forget the spare!)
