BW Viscous Coupling differences to CDL

Clunks are Not Good.

In the Classic, the mechanical wearing bit is the output shaft (rear drive) - the splines wear themselves, and the day you swerve to run over a black cat - and hit the Chinaman as well... is the day they strip, and you have NO drive going to the rear. From there the wallet starts bleeding.[bigsad]
But when working they are awesome in sand - so I'm told.

IF, a very big 'IF', the VC was still produced in sufficient numbers to keep the $$$ at a reasonable figure, I would have replaced mine, kept my Classic in AWD instead of bodgy RWD...and most likely not have pirouetted on that fateful wet day.. and stayed out of the trees.
And I would not have sold it. Maybe.

If only one could design a difflock that could go into a bw...

Apart from the vc being a consumable item, the other downside is trying to reverse down very steep loose terrain. At such a slow pace it essentially reverts to being an open diff.

Well from my experience I don't really agree.
I always found the first 10 metres from start on sand was a struggle until the VC heated up and locked.
From then on OK.
But I recently did Teewah beach in the D2 and it seemed SO easy starting on dry sand just North of the corduroy track with CDL engaged after stopping for the inevitable photos. The TC didn't even kick once.

Having said that I have towed my camper trailer along dry sand on Stockton with no problems with the old RRC keeping in in low ratio to keep the revs over 2000RPM when single cars were getting bogged.
