Title: Will a Jeep CJ steering box fit my 81 eagle?
Post by: priya on April 19, 2021, 10:58:06 PM
The steering suddenly became quite erratic on my 81 SX/4 so I need a new steering box.  The spousal unit doesn't want to buy a remanufactured unit as he says they are usually in worse shape than the core you return to them.  I read that the XJ  (Cherokee) and ZJ (Grand Cherokee) Jeep boxes bolt directly on, hubby knows someone with a Jeep CJ, will that steering box swap to my Eagle and do you know what the steering ratio is on it?

After some digging I found the CJ steering box is either a 17:1 or a 17.5:1 ratio:

Apparently it has a 13/16 input shaft and 36 splines, although I still don't know if that swaps for the one in my SX/4.

I don’t think so. I think the Jeep CJ boxes are 4 bolts for mounting and I think the hose connections are different too.
I think the Jeep XJ Cherokee boxes might be the same. Still looking into it as I need to replace my box, pump and reservoir too.
If the XJ boxes turn out to be the same I was planning to use a heavier duty aftermarket box.

Thanks.  According to this thread the boxes from the XJ and ZJ are direct swaps:

I would say an xj does swap, but you probably already seen that.

I followed this link and read that thread, including eaglefreek's comments.  Seems to me he did a more detailed write-up when he did the first steering box swap so if you haven't found that one yet, it may be worth doing some more digging.  Good luck!!

I've been through the whole steering and suspension section and didn't notice it,  maybe I missed it or perhaps in project cars?  I'll have a look again,  thanks.
