Are hard turns bad for differentials?

[Deadly BlaZe]

I was just wondering, are making hard, tight turns at high speeds bad for differentials? How about drifting, sliding, and doing donuts? Just curious.

on awd cars, yes. doing awd donuts is probably the worst...all of that stress to get the tires to actually break loose gives hell to the drivetrain...its not as bad on fwd/rwd cars because they can get the tires spinning enough to where its simulating normal driving...or atleast somewhat normal driving. Ive never heard of hard turns being bad for differentials, but I could be wrong. I wouldnt do any of those listed, even tho theyre tempting.

Not so much the differentials, but yes, very rough on the viscous couplings. They just aren't meant for extreme use, and in the DSM AWD scheme, a slipping tire causes the drivetrain to try and go solid at both ends, so the other three tires are fighting the slip of the one. All this is run through the VCs. I have no idea of how much abuse they'll put up with before failing, but in the case of towing one end on the ground -a similar situation- a block or two can destroy them.
AWD DSMs are pretty slick little cars, and their drivetrains are robust in semi-sporting use. But burnouts or off-roading and similar abuse will take them out pretty quickly.

This is why I wish there are aftermarket LSD's for the rear end of our cars .
