The will it work thread?

After being "diffed" a couple of times I thought that running separate brake lines to all four wheels and having two thick rollers each side of diff on the rear and one wide one on the front. This way you've got a chance to claw your way of deep ruts and over rocks. The rollers would be in two halves so installment would be simple.

while there is merit to this idea, and it could probably be done with a lot of rnd, it wouldn't be a simple as bolting two bits of half round together over the diff.

Firstly, if it did spin, it would wear away the diff housing in no time.

Secondly, I don't think it would spin, because the amount of friction would be too high.

So, in order to spin, and not wear away the diff, it needs bearings.

Fitting bearings would be possible with enough time and $$$, but that size bearing wild be fairly expensive. Also, you would then need to put on seals etc, as mud water could easily get in and chew out the Bearings.

Thirdly, why I wouldn't do it, instead of just having the diff pumpkin to get hung up on, now you have the entire length of the diff, reducing diff clearance by at least a couple of inches.

Not having a go at you, just like to think up problems/solutions for things.

I'm not an engineer, just a humble fitter, so someone feel free to tell me I'm wrong.
