Re: diff locks
It is fun to experiment with the difference between locked vs. open diffs!
Have you noticed the description in the QTC Owner's Manual about use of
diff locking for competition? You gotta like the fact that they weren't
too scared to put that in the Owner's Manual!
Has anyone actually experienced diff failure due to locking the diff under
dry circumstances? There is no doubt that you are going to suffer extra
tire wear when both tires are turning the exact number of times in a turn,
but I don't see any cause for increased heating in the diff simply because
the diff is locked. The dog gear ensures that there is no energy spent in
the diff other than that coming in from the engine. I could envision that
happening with the anti-spin diffs that have a friction-based coupling
between the output shafts.
