Suspension issues

Hi,

I'm new here but figure y'all will have the answer. I recently purchased a 1980 CJ7, has I believe a 4" lift with a 2" body lift. Either the rear is sagging or the front is high, I don't know which. Measuring the rocker panel under the door directly in front of the rear wheel and directly behind the front wheel, the front is 1 1/4" higher. The rear has a pretty heavy duty spare tire system with a 35" tire, two jerry cans and a storage rack. Could the rear be sagging? I plan on removing the 2" body lift and running the stock body bushings, and Probably replacing all 4 springs. Anyone have any ideas on whats going on?

You got a lot of weight on the back of it... take all that stuff off and it will probly sit level. If you want to keep it, You could always use an add-a-leaf in the rear to level it as much as possible..

The shackle reversal on the front adds an extra inch of lift and the extra weight on the rear is sagging it a bit. You can add a leaf to the rear to help with the weight and maybe go to a slightly longer shackle in the rear to level out the Jeep.

I'll try that and see how it goes.

What can I do in the front to bring the front down? I bought the Jeep like this, so I have no idea what springs are on it. I'd like to bring it down a bit and go with 33's instead of 35's but its got 4.88's. I think I can redo the carrier system in the back with some lighter gauge material, and drop the jerry cans.

I agree. Removing the jerry cans and moving the spare closer to the tailgate will probably help.

You will indeed need 6" of lift in the back to cope with those big tyres. I would concentrate on raising the back than lowering the front.

A good source of suspension parts is Rockauto, good brands include Moog and to an extent MORE. However your situation is one where you need custom parts.

What size tires do you run? I'm not opposed to going down to 33's. Even with 4.88's I'm going to do the AX15 swap so gearing should be ok on the freeway.
