jeep springs are supose to be flat even ask the dealership, ive went through this for several weeks looking for an answer and the best one i found was to park on flat ground and measure from the ground up to the rocker panels on the front and back should be level. like i said mine looks the same as yours, but when measured its a 1/4" lower in the back, but only cuz i have stuff back there, and even another thing to look at is that the w.heel wells are different sizes and different hieghts

 

The tallest years are the 94 thru 2001 4wd models "64 inches". Mine is a 90 and I had the same saggy rear leaf springs. Mine sagged in the back really bad. Our Jeeps were 63.3 inches stock. And with 150k miles or more that will measure even less.

I am not sure, but I have seen a lot of the newer XJ's with less rear sag than the older years. So I think the rear springs got a little better in the later years. Because at the Jyard I see a lot of the newer Jeeps that have more miles than mine with rear leaf that are not as flat as mine.

Also a lot of people will put the 235 series tires on a stock height XJ because that is the biggest recommended tire that you can put on a stock height XJ.

 

I don't think flat rear leaf springs came stock on the new production Jeep Cherokees.
Leaf springs are not efficient when they are flat. They are supposed to have an arch to them for load handling and ride.
If you look at the brochure photos of the 1991 and 1997 you will see the 1991 has about the same rear wheel arch gap as the front. In the 1997 photo you will see that the rear arch gap is bigger than the front which means the newer models had more of a rake than the older models. And I have noticed that most of the newer models sag less than the older ones. My 91 was sagging really bad and it only has 180k on it. Some of the 250k newer 97+ models I have seen driving around and at the Jyard are noticeably less sagged in the back than mine was. And even with my sagged rear leafs, they were not completely flat. They had a slight arch to them. The bushing eyes were higher than the middle of the leaf springs.

 

@Cheroklee Laredo: Will those alloy rims on your 1999 fit my 94 Cherokee?
I'm looking to replace the rusted steel rims.

Thanks, BMH

 

yes they will. just fyi.

Basically all xj wheels are interchangeable..they are all 5x4.5 bolt pattern.
