92 Pickup differential and rear axle housing questions
On my 1992 Pickup - 4x4, 6 cyl, Extra Cab the rear pumpkin ball (axle housing) has rusted/rotted through and is leaking badly. To correct it, I figured I would just get a used rear axle assembly and swap out the whole rear end, but I've come to realize that finding one with the same ratio as mine (4.30 - axle code G284) is harder than finding hen's teeth. Although I am very capable mechanically (I just replaced the front CV shafts, which got interesting!), I've never worked on or replaced a rear end on anything, so I don't know much about it. Since I only need the housing, I am hoping that I can get any axle assembly that works with my model regardless of ratio and simply bolt the differential/carrier from mine into the new (used) one. Is this possible and if so, is it as easy as it sounds?
I'm hoping someone can answer the following -
Are the axle housings same for 4Runner as for Pickup?
Are the housings different for ABS and non-ABS? In the service manual pics, it looks like the ABS stuff bolts up to the diff/carrier, not the axle housing.
Are the rear axle housings identical between 2wd and 4wd?
Are the rear axle housings different for different ratios?
If it is possible for me to simply put my old differential and axles into another housing, what year and models have a rear axle housing and brake assembly that will work for me? Note that my brake backing plates are pretty rusted so I would like to use the ones from the rear end I purchase rather that use my old ones.
I has come to my attention recently that new OEM Toyota parts are obscenely expensive - to the point where I would never even consider buying them, so replacing with new parts is not an option.
Any advice on this is greatly appreciated.
Thanks,
Ken

Why not just patch the hole?
How bad of a leak are we talking about here. I live in Canada where the salt is layed down as thick as anywhere and I've never seen a rear dif housing rusted through to the point of leaking. If it's not structural just have someone plug the pin holes with mig welder and keep on motoring!!

I'm hoping someone can answer the following -
Are the axle housings same for 4Runner as for Pickup? No, 4Runner is coil sprung
Are the housings different for ABS and non-ABS? In the service manual pics, it looks like the ABS stuff bolts up to the diff/carrier, not the axle housing. Depends on whether its 2 wheel or 4 wheel ABS. 2 Wheel ABS and non-ABS housings are the same
Are the rear axle housings identical between 2wd and 4wd? No, 4wd is spring over, 2wd spring under and smaller
Are the rear axle housings different for different ratios? No, 4WD has same housing regardless of ratio
If it is possible for me to simply put my old differential and axles into another housing, what year and models have a rear axle housing and brake assembly that will work for me? Note that my brake backing plates are pretty rusted so I would like to use the ones from the rear end I purchase rather that use my old ones. 89-95 EXTRA CAB ONLY

Pretty sure most of this has been covered before, but if not, there ya go.
Might spend some time searching next time as well

BTW - I did spend about 45 minutes searching here for the info but most of what I found was scattered tidbits mostly dealing with 4Runner, which as you point out is not compatable with my pickup. I did find one post that suggested that carriers can be swapped, but it didn't tell me what housings would work for my year/model.
Thanks,
Ken
