Just about to chat to my diff builder, see what he reckons about oil starvation to the pinion.

If I can make it work I'd like to. Get some caster back, and sort out my front prop angle.

I haven't seen this done? Good thing or bad not sure which?!

Jimnys are high front pinion, so they must be reverse rotation?

I need to find out how the oil feed works.

Surely the ring gear just splashes enough up that it runs up the pinion a bit and lubricates the bearing too.

Can't imagine it being too over complicated.

"A mechanism to move oil to the pinion" Is the best I could find on google.

Umm, it's not quite that simple I don't think, but I don't think it will matter the speeds I go at. Cruisers have a like a snorkal with a pot of oil, so the diff is completely full. That's early 70 series axles.

Not to sure, need to do some reaserch on it.

If you look into the diff carrier you'll see that there's a channel for the oil that is thrown off the ring gear to flow down lubricate the pinion bearings. Pretty sure its a one way design and only has it at the top so I'm not sure you'll be able to get away with just flipping the diff. Jimmy's do have hi pinion front diffs but I'm pretty sure they are more similar to a 410 diff than they are a Sammy diff so I don't think you can swap Sammy or front vit r&ps into one, plus you also need to run 26 spline for your shaft.

I don't think it's going to be that easy to do?

Just read a long thread on pirate.

No Suzuki specific stuff.

Only one mention of a rather high-end expensive pump.

Next most technical was a few little "paddles" added to the ring gear to flip oil that way.

Then the people that just over fill but seem to have issues with blowing oil out of breathers etc...

Then the trucks like yours that aint used on road (mainly rock crawlers) that rely on filling to a reasonable level and it just getting moved about by the truck rocking forward and back, the transfer from the ring to pinion, and generally not going fast enough to cook them!

More to the point I have spoken to my diff builder and he has advised me not to do it, so that's that out the window !!

Anyway onward and upwards !!

If Jimny's have been built like that from factory, could you look at swapping in a Jimny diff assembly (assuming they're not weaker, I know some Jimny parts aren't as strong)?

I'm fairly certain that they fit the same Lockrights into Jimny's that they do into 413's and Sammy's, so it might be a straightforward swap?

Anton ;) front and rear jimny diffs are different, the rears are compatible with sammy lockers but the front aren't.
