Clarification Wanted

I thought it was 1" shorter in general :dunno:  But then again I don't think there is a real visual difference in the 4wd vs 2wd heights

@ Hornbrod: From what you're saying, the OME coil will lift a 2WD 2" as well? When I measured the ride height from the frame rail (based on instructions on this forum) my ride height was exactly where the page said it would be. That leads me to believe my coil springs are in good shape as-is.

As mine was.  :thumbsup:

According to the factory service manual, a 2WD MJ rides 1 inch lower than a 4WD MJ.

 

Curiously, they do NOT list a similar difference between 2WD and 4WD XJs.

Hmmm that makes me wonder... I wouldn't think they would have two different springs..but then again.. Lol

I think we need to post this in the chat section and see if we can get some people to go measure their ride heights and compare 

 

Edit: is that 1" all over? Like front and rear?

Eagle, that shakes up quite a few assumptions I've made. How would the ride height of the MJs compare to the XJ? Would a 2WD be the same ride height as the XJ or 1" lower?

Must be an AMC FSM then. My 1991 FSM makes no mention of a difference in the ride height between 2WD and 4WD MJ in the model weights and dimensions table. Of course, it could be somewhere else, but this is where it should be listed. The only way they could be different heights is via stiffer springs, and the 2WD and 4WD used the same suspension parts for the base vehicles. I'd like to see a scan / image of the FSM page to stating this.

I thought I had posted this info before. It's from AMC service bulletin I.S. 14E, dated June 1986. This is where they describe checking the ride height by measuring from the axle tubes to the frame rails (rather than center of hub to bottom of flare, which is the way we typically do it .. if we have factory flares).

 

Skipping over the procedures, the stated measurements are:

 

Front: "On two-wheel drive models, vertical distance should be 17 cm (6-3/4 inches) plus or minus 13 mm (1/2 inch). On four-wheel drive models, vertical distance should be 20 cm (7-3/4 inches) plus or minus 13 mm (1/2 inch)."

 

Rear: "On two-wheel drive models, vertical distance should be 21 cm (8.2 inches) plus or minus 13 mm (1/2 inch). On four-wheel drive models, vertical distance should be 23 cm (9.2 inches) plus or minus 13 mm (1/2 inch)."

 

 

I can't scan it because the paper used in those old AMC manuals is basically like thick newsprint, and if I try to bend the pages enough to sit somewhat flat on a scanner I'm afraid I'll trash the book.

I bet you could take a pciture of it   :dunno:
