Re: [ihc] Another brake (?) question

Hello David,
 
By any chance does your rear diff have a track-loc in it??? Does it do it
worse when hot??? If so it is likely the LS clutches chattering. There are
additives to prevent this. I solved a similar problem in my Scout with the
Mobil 1 gear oil. I espically noticed the problem when pulling a trailer up
a grade with a lot of switch backs or when pulling a trailer onto the road
from the sholder (similar to you pulling out from a mail box).
 
For your use an open diff would probably be best as I'm sure the dragging
clutches don't help your gas milage or the wear and tear on parts.
