How does VLSD work?

Pretty basic tech question, can someone describe (or direct me to) the how and why our transaxles are able to work so well. In comparison to other (both higher and lower HP) fwd cars i have driven, very few have "stuck" to the road like the Max. Thanks!

Personally, I'd like to see someone do the quaife ATB install and see how it performs vs. vlsd.

Get Quaife to actually make one, and then see what happens.

you don't rebuild them. sealed unit. throw it away and replace it.

and the only way to tell if it's gone is to test it on the car. read your friendly FSM for instructions.

Since the diff part number is the same for the 3rd, 4th and 5th gen, I'm fairly sure a quaife would fit in the VE trans. No?

I had to check to make sure I wasnt crazy, but you can absolutely rebuild these LSDs. FSM shows you how.

Look more closely. the vicsous coupling (the main part of the VLSD) is a sealed unit and is not rebuildable.
The differential itself is rebuildable, but the vicsous coupling is not rebuildable and only comes as a 'differential housing assembly' from the factory for $768.
Or you can buy the entire differential for $1028.

Of course youre right. What do you think about the quaife fitting in the VE trans?

I'm waiting on word back for availability on one. Neither Cattman nor Quaife stock them, and since the strength of the dollar to euro has gone down, it would cost nearly $2k for one if they made another batch. So I'm currently in a search for someone who's got one sitting on the shelf somewhere.. supposedly one guy bought several for "future projects" and never installed them.
So I'm waiting on word back from him.

Assuming there is actually one available and it actually fits, I'll update you guys on the news later.

sorry i wasnt clear ,i meant the vlsd unit itself
as far as the trans re assembly itll be a first for me but since i used a big flat piece of styrofoam so i could stick the bolts,pins,clips etc. into the foam and
write the descriptions next to each piece and not lose or mixup stuff
it should be good
looks like im s.o.l. on a new unit so...i guess i could rebuild it and see what a crack in the vlsd housing case does,or sell it off as is,or keep it for parts
its from a parts car that i got enough money for already so im really only like
50.00 into it (new front shaft bearings)+free "pro"bearing install
