Outer Limits 4x4 Board

Just thinking aloud here.

Has anybody heard of running a front Hipinion diff in the rear axle? I understand the CW&P rotation would be on the weak side if used in the rear, but would using a Lopinion CW&P from a front diff solve the problem if it will fit into a Hipinion diff.

No comlpetely differant

If you break the gears in proply they still hold up in the rear
Mate runs 4.8 H/P rear and canes the liven P$ss out of it and its fine

i have a mate that has hipinion in the front and rear of a zook with hilux diffs

I have been using a 80 series hi pinion front electric locker in the rear of my 4 runner for 7 years
I had to change the bearings in it about 3 years ago
I have a VR lexen engine in it R 151 gearbox fitted with the 5.15 Dyna 1st gears and dual transfer cases 2600 engine rpm for 20 wheel rpm
and I have towed a fully loaded semi 42.860 tons with it

thanks for this all.

4sum4, what type of truck is it in and what motor powers it?
Toyrex that sounds pretty solid. This would be used in a Disco that puts out up to 140kw and 450Nm through a factory transfer case.

I presonally wouldnt do it. A disco is a pretty heavy truck, and I would just a run a low pinion for peace of mind.

I think you're right. My initial thoughts were that the tailshaft will be more prone to rock damage, but I'm doing the conversion for strength so why then compromise it. LP will be the go then. Thanks BJ on Roids.
