Compatability of '85 and '95???

[MT Tatman]

A neighbor has a '95 4runner with a blown-up 6cyl. I have an'85 4runner 4cyl.
I am only in need of a good rear end, maybe driveline and leaf springs.
Are those bits interchangable with a 10 year difference in age??
He is willing to part it out, so if they will work, I am in business!

The '95 has coil springs in the rear (and are likely shot, anyway). For driveline parts, the V6 uses a 23-spline shaft, while a non-turbo 4 uses 21. I'm no expert, especially on the 1st Gen (I've had 3 2nd Gens), but I think you have some compatibility issues there.

I think the only thing those trucks are going to share is going to be front suspension and the differential. The rear third and axle should swap, but you'd have to mod the axle for leaf springs instead of coil perches.

Thats correct.

But all 8" differential flanges are swap-able. Thats why TG makes the triple drilled flange

I believe the 95 rear axle will be wider than an 85. The IFS 1st Gens were 3 inches winder in the rear than the 1st gen solid axles. I have a IFS V6 rear on my solid axle 1st gen with 1.5" spacers on the front axle to make them equal. The V6 rear axles are supposed to be stronger...

The V6 might also have 4.88 gears. What diff gears in your 85? I think most manuals were 4.10.

You can maybe take the drive shafts.

V6 would have bigger brakes on the rear too.

You can take the steering box if you plan to do crossover steering.

Did 95's have e-lockers?

Thanks folks, I figured as much, but it was worth asking. Looks like I may as well save up for a fancy fun time locking rear end.

Without really knowing your setup....and what your truck is used for.

Being you have an 85, means solid front axle, means the rear 3rd member fits in your front too.

If you have bigger tires, or plan on bigger tires then you might want to change your gearing too. If this dead V6 is a free donor truck and it has the 4.88 gears then it already has gears that are setup to go. This means don't need to buy gears and don't need to pay for setup.

Then you look for a fancy fun time locking rear end also with 4.88 gears.

I believe the E-locker didn't come in until at least the 3rd Gen, CAN-03, and the stock gearing wouldn't be higher (numerically) than 4.56 (auto), with 4.10 in the 5-spds.

The 95 has a 7.5" front diff and will not fit into a 8" solid axle housing. So you would need 2 rear IFS diffs to make it work.

I believe he was referring to putting the REAR '95 diff in the FRONT '85, which would be 8" to 8". Still, seeing as how it's probably a stock open diff with stock gearing, it really wouldn't accomplish much other than getting the beefier V6 diff. Might as well wait for a limited slip or selectable locker sometime down the road.

Right I meant rear 95 for front of 85. Not knowing the intended functionality for the 85 the thread became an exercise in possibilities. If this 95 has lower gearing, even if open and is free for the taking it would fit the front, and is already setup, no need to setup the RnP. Only need to find an elocker diff for the rear. One locker better than none.
