Yes, I searched, but no one has a setup similar to mine...

I have decided to put a Toy 8" under the rear of my Jeep Comanche truck, I would like to use a high pinion 3rd for obvious reasons. I understand that a high pinion is weaker when run in the rear, but the Toyota axle thing is all pretty new to me. So I would just like some opinions on if a high pinion third will hold up under my truck....

about 3500 pounds (weighted heavily to the front), about 180 horse and 220 lb/ft torque, measily gear reduction (about 45:1), 35 inch tires... not too hard on the go pedal....


thanks guys

The superior Toyota parts will reject your jeep. :flipoff2:

Seriously, it doesn't sound like a good idea to me. If it's not a good idea for a Toyota, it's gotta be a worse idea for you.

Can you fit or modify to fit standard rotation gears in the hi pinion , or does it rely on reverse rotation for oiling duties ?:p

Don't do it. Everyone who has tried to run a HP Toyota diff in the back has destroyed it. Talk to Marlin about it and he'll give you very good technical reasons why it's a bad idea. Stick with standard cut in back and go HP in front.

If it rotated in reverse, it would be going the wrong way.:rolleyes: Reverse-CUT is the term you are looking for.

If you run a high pinion in the rear, you will eat pinion bearings for breakfast, because they have no way of oiling themselves in a rear axle. If you are really stuck on putting a toy rear axle under your jeep (is this some sort of theme today?) then go with a v6 third, and deal with the low pinion. But also, you are going to have issues with spring over versus under, stud pattern, mating of drive shafts etc.

Really!! These wankers want toy performance in jeep clothing - what's the deal? Also, how many of them will get $$ into it before realizing that their SAE tools wont fit?

....waste of perfectly good toyota parts, putting them under a mail truck.

TOY PARTS ON A JEEP?!!!!!!!!!!

Even if you put the motor/tranny/t-case/drivelines/axles into it, it would still be a HEEP!:flipoff2:
