You will need more than just the length of the housings to do that. you need to know the distance from spring perch to spring perch, distance from perch to backing plate on each side and the offset of the center section, so that when mounted, the driveshafts are not running at an angle. You also need to find the pinion angle at rest: (the amount of upward or downward pitch of the pinion)
In making these measurements you can avoid the possibility of having one axle protruding further past the springs, or damaging universal joints by having them run at an angle that isn't correct.
You can find lots of info on swaps at several online jeep forums. Many of the people there have done swaps and have taken those measurements and have the info you need to do it correctly.
If you have access to a welder, cutting tools and jigs, that opens up numerous possibilities as any differential can be used in any vehicle if it is properly prepared before install!! Just offhand, i don't think that the wagoneer units will fit because it is much wider than a cj. Try jeepforums .com for swap info.
good luck

If i have two cj7 jeeps but rear end housings look a little diffrint but both have a 258 engion in them how do i know that there enterchangable

One of your Jeeps may have a heavier duty axle option. The main worry you would have would be are they the same gear ratio. If you swap in a rear end with a different ratio, and use 4wd, it will tear your drivetrain apart!

How do you remove the pully on power steering unit for a 1983 CJ7 with 258 engine

Most decent pullers will get it off but the main problem is that to put it back on, if the center of the shaft is not threaded, you will need a press or you can do damage to the pump. (most machine shops can do that for you) Also, make sure that the pulley is in the exact same position in relation to the other pulleys when you are finished or you will start spitting belts off.

Replacing front shackle 1983 jeep cj7

Shackles are pretty straight forward. Remove the existing bolts, change the shackles and reverse the procedure to install. Good idea to change the bushings while you're in there if they are at all questionable. It's best to do this with the CJ in the air, supported on the frame and use a floor jack under the axle to lift/lower the spring in/out of the shackle, one side at a time.

Swaping a manual jeep trans for an automatic trans

As far as the swap goes you can get everything you need from a you pull it junk yard. But it isnt going to be an easy swap. If you have never done this type of work before I would highly recomend consulting a professional.

But I must ask, why on earth would you want an automatic trans for off-roading?!?

Rear wheel bearing/axle problem

1. There should be a metal tag on the diff cover, held on by one of the cover bolts. This will help you ID the unit. If it's gone then someone will have to look at it that knows these rears. If the axle surface that is scored rides on the bearing surfaces, is scored then it needs to be replaced. 2. the easiest way to know if you got all parts of the old bearing out is to look at a new bearing. 3. I can't remember the manufacturer (maybe sosmetal?), but there used to be a bearing setup that changes the position of the bearing & seal on the axle so it rides on an undamaged part, so you can still use the axle. Check with any local old style parts house (not one of the new fast food type places) you may get some help there.
Also... if the bearing failure was extensive, make sure you remove diff cover and clean out all debris from the gear set housing... any junk left behind can destroy pinion and side bearings!!!
