exact part numbers to replace front and rear springs?


Recommended Posts

The rubber is shot on the leaf springs on my 88 long bed. I also have 235 mud tires so a get some rubbing. Also a noticeable rake. After months of reading every post I can find I'm still not sure what I should buy. I'm going for a stock look, but, want a slight lift in the front and would rather not have a rake, but, not sure what I should expect/Want that way. I'm convinced I should just replace the leaf springs. Can someone just tell me exactly what coil, leaf, and etc I should buy?

Get a set of stock leaf springs from either Hell Creek or National Spring (both offer CC membership discounts) and install them. Since it's sounds like your original rear springs are shot, you will get some lift out back, unpredictable until installed. Then match up the front as needed for the stance you want using Up Country or ZJ coil springs or use spacers with your existing coils.

Your leaf spring bushings can be replaced simply at home. Buy polyurethane leaf bushings marked for a Cherokee, like Daystar KJ02008BK. Take the springs out of the truck, get your drill out with a 1/2in bit and drill out the rubber until it's all gone. Take a drift or metal chisel and hammer out the metal sleeves. Done. The poly bushings install extremely easily and cost less than stock type bushings.

If you've got a rake still then you're not sagging. You just need new bushings and Quadratec, Summit Racing, ect all sell them for a couple bucks. No sense in replacing the rear springs if they don't need to be and you're not lifting the rear.

 

As for the front you could just throw on some coil spacers or find some ZJ V8 Up Country package coils. ~2" lift coils should about level things out though. That or get 3" coils in the front and some 1-2" lift shackles in the rear to go up about 2" overall once you're leveled out. I'm not sure of the exact difference between rear and front height on an MJ since the rear end is higher to compensate for loads in the bed but you can measure from the center of the hubs to the bottom of the flares front and back and that will tell you the exact heigh difference.

 

Are you rubbing when turning or are you rubbing from flex?

 

If it's turning adding a couple washers to your steering stops should prevent your tires from hitting the LCAs. If it's the rear you can just get longer bump stops to limit your up travel to where the tire isn't going to hit anything. For the rear you'll want to wait til you get your suspension figured out though.

In case anyone is interested. I bought the 3-1 springs from general springs (when I mentioned Comanche club he gave me about 10% off) and bushings for the rear shackles from AutoZone. All the other parts had some surface rust but otherwise in good condition. All came off with some elbow grease. I cleaned up the parts then coated with por15 and installed them wet then touched them up later. Used a large socket to push the old bushings out of the shackles. Other than lots of swearing and many scraped knuckles it went smooth and took about 6 hours by myself. Also replaced shocks front and rear. I took dons advice and jacked up the front to check the leveling. On level ground I set a level on the bed. With about 1 inch of lift I'm left with a hit of a rake and the visual look I like. My plan is to eventually install one inch spacers in front. I Decided to wait on that as I believe I'm pretty close to factory rake and am now prepping for paint.
