Thread: What actually stops an e-diff retrofit?

It's actually a very robust diff. The clutch pack is activated on a cam. If anyone is interested I can post some pictures of various internal bits of interest.

Yes please. Also, any pics of broken ones?

There are plenty of pics of broken ones, but mostly they are all the same problems, rust, excessive wear on the gears. The clutch packs never go bad, there is so little movement, and virtually no wear.

Here is a picture of the typical noisy diff, or at least one of the reasons they get noisy. Note the rust, which is typical.




Here you see the center piece all split apart, and cleaned read for reassembly.




Here is a closer picture of the clutch pack. Each plate is separated by a small shim/spacer. Note the flange (rust colored) in the back ground.




Plenty more pictures of bits if you are still interested.

Yes please! Keep them coming!

What's the cause of the rust???

My theory on the rust is, that the heating and cooling of the unit causes condensation, which does not vent out. Left for long enough, it gets hold and begins to form a rust paste. The result is disintegration of the bearings, and excessive wear on the crappy gears. These gears can/do occasionally give way as well. I believe the best action is preventative, which is changing the oil more frequently to keep the moisture flushed out, and ensuring the vents are connected, and nothing is plugged. This will extend the life, but eventually every unit will need proper rebuilding, bearings wear out.

Here you will see a pinion gear from yet another diff, it's not a great shot, but you can see the rust on it. The Crown Wheel, Pinion, Bearings, and seals go directly into the scrap bin when we do a diff, and brand new ones are fitted. The new ones are better quality, tolerances, with a quieter operation.



Here you will see the clutch packs, laid out so you can see the spacers between each pack. Note: the one pictured here is the diff in my own truck today.




Here is yet another diff, just after splitting the case. Note the wonderful colored oil. What do you suppose we will find when we open this up?




Plenty more available if there is interest.

Diffs lock symbol changes to Red when locked.

And no you don't require the screen to have a eDiff.

And the strange thing is the rear diff can lock independent of the centre diff..

both.
