My 5 spd manual, 4 wd truck is throwing oil from the front of the rear differential, and sings when I let off the gas. I planned on getting some junkyard springs this weekend...now I want to just get the whole rear end with the springs. I know the leaf springs off a trooper up to 91 will fit. what about the rear end? Am having trouble locating one from a pickup the age of mine. If I do get a newer one, will the disc brakes mess with me?
(This must be the rear end symbol <img src="/forums/images/graemlins/butwiggle.gif" alt="" />) PS please hurry this may not last another week. PPS I searched in archives and this forum..no luck.

Idon't really know much about the early pickups other than they are the same as the chevy LUV's. I will suggest what I believe to be true. The rear axle is probably an Isuzu Corporate 10bolt. Its probably an identicale unit as whats in the rear of an early trooper (drum brake models prior to about 1988). If you wanted rear discs, a swap to a larger 12 bolt or possibly a d44 could be done.
I can not say what it will take to hook the drive shaft up.

However it may be that you simply need a new pinion bearing and seal. Which could cost more than a junkyard axle, but worth checking into.

Its possible that a front third member from any later 4wd isuzu with a 10 bolt front diff may bolt in if you can't find a whole rear axle.

Hopefully someone can verify that any of this is true or false. It seems reasonable, but I'm not totally sure, so double check first.

one link worth checking might be Chevy Luv's

Good Luck,

thanks Mike. I got some advice from somebody else too, and I have a plan. there's a junkyard on my way home from work. they have a P'up like mine with rear end, and some Troopers too, with springs and rear ends. I will measure stuff.

I already know the Troopers will probably have 4.56 ratios, whereas mine is 4.10. That sounds fine, as I want to go to bigger tires and wheels anyway and I don't want to lose torque. Or if the upgrade to Trooper carrier looks too tough for my no-backup daily driver, I can get the P'up rear end and some Trooper springs, which are stiffer.
