Posi or lockup rear upgrade
Hey there,
I have a 94 Ranger XL, 5 spd, reg cab LB. I found a posi rear off a 90 4x4 ranger with the same drivetrain.
Would that just be a bolt in as well? Should I bother taking the leafsprings as well?
Should I just take the gearset, or the whole axle?
Thanks for any help.

Might as well get the whole axle if it's in good condition. I do believe it is in fact a bolt in. You need to do some measurements to find out for sure, but as far as I know everything will line up aight.

I second the reccomendation of removing the entire axle. Without the proper tools getting the pinion depth and gear backlash set correctly can be a pain.
You should just be able to use your existing leaf springs and brackets, unless the ones on the junkyard truck look to be in better shape than yours.

yeah as long as your there just get whatever looks better than your truck parts!
Are the gear ratios the same? Somebody correct me if I am wrong, but I believe if you change the rear gear ratios you will have to change the front gears as well.

Just so you know, this is a 2wd Ranger I have. I am taking the rear axle off a 4x4 Ranger. Reason being is a posi, or lockup rear end seems to give better traction for hill climbing, and in bad weather.
Does this change anything?

Is there anyway you can measure it before you buy? I heard at one point that the pre '93 Ranger rear axles were 2 shorter in width than the '93+. I can't seem to find the source that said that right now, maybe there is a reason for that.

Alrighty,
I went back yesterday and checked the rear end.. someone has removed the cover plate and partially dissasembled the differential. The two axels are out on either side now.. and the gear cluster is exposed.
They gears look to be in good shape, not worn or anything.
I have a friend who is really experienced in mechanical stuff, owned and ran a shop for 32 years, did race cars etc.. he's 63. With his help, would I be better off just getting the gear cluster? I may as well just bring him down so he can look at it with me.

If he can set up gears, then just swap out the carrier. If the gear ratio is any different than what you have now you'll have to get the speedometer gear off of the donor vehicle as well or you can buy the appropriate one from a dealer for less than $10. I think the hold-down bolt takes a 5/16" socket.

To be on the safe side, get your hands on Hollanders Interchange. It'll tell you what fits and in some cases, it will tell you what to do to make it interchangeable or what the difference is. The library (at least in my area) has copies in the reference section and some junkyards (usually the upscale ones) will have a copy. It's very expensive.

Wow cool. I'll be makin' that trip before long. I just gotta find a way to convince the gf to cram in the passenger's seat or in my lap. (Bring two people home from school every day, 3 seats in the truck, down to 2...hmm dunno how that will work)
