Differential Locking

[msalem@ursa12.cs.utah.edu (Mark Salem)]

Hi Guys,

today was our first REAL snow storm, and what a storm!  I know someone must
have asked this question before, so I'm sorry if I'm bringing up a question
that gets asked VERY frequently.

Could someone discuss the center and rear differential locking mechanisms;
I know what they do, but could someone talk about what speeds they're safe
at, when to lock center vs. both, is it worth it since that disables ABS,
etc...Any info would be REALLY appreciated...

THANKS,
   Mark.
