UZJ100 4x4, 4wd system explained

[stonepa]

I had the virtual equivalent - a Toyota RAV4 EV - for a while. Fantastic commuter but absolutely no way that was going to be lifted.

Its not the Axle its the spider gears in the diff.
I have seen it happen in loose gravel. Pretty much any time the tires spin I would worry about it.
You will know when it happens.
If I had one and planned on wheeling it I would save my money and throw an ARB up there before I did anything else.

Thanks! it appears it is famous weak link but doing ARB locker takes care of that issue. It's a pricey up grade but the output of doing it makes the vehicle incredible.

Thought of this thread when venturing over to ExPo today.

Looks like the 3rd edition of Four-by-Four Driving just came out.

May have to get me a copy for Christmas in order to slice through "the marketing jargon".

Update: Reading the book review on Overland Expo, according to Mr. Sheppard "there are basically just three" four-wheel-drive systems. "The profusion of trademarked drivetrains are all just slightly tweaked variations on a trio of themes." Looks like an interesting read.

Cool Thanks! I have been extremely interested in the various systems of how they perform and how well they perform.

Jody, please use the multi-quote or edit buttons instead of posting repetitively, it keeps threads much cleaner.

Not just the spider gears, but the ring gear. Maybe even more so.
Here's some data. SandiegoCruiser was the most recent spider gear failure, but most over the last few years have been the ring gear failure caused by the carrier flexing.

At the very least, you should know how to get yourself off the trail by making your 100 a 2WD version.

Skyline Hunt 1-09 thru 1-12

Took the UZJ100up to skyline. You cant beat the suspension vs a Tacoma. My friend's Tacoma's ash tray was rattling out on little rocky flat roads. The comfort and capability is there with the Cruiser, even in ruff stuff. My only gripe is weight and power. I sunk up to the frame once much faster than I thought I would. Overall, The 100 series is a great off road vehicle.
