Re: 4kq diff stuff

[Todd Phenneger <phen9461@uidaho.edu>]

Hmmm, nice to know mine isn't the only loud one.  Rear diff holds 2 liters
I think which is about 2 quarts.  ANy how, it makes noise while
accelerating and decelerating but with no load on it, it is quiet.  IE,
3rd gear is noisiest( after that road-wind noise may drown it out.)
Anyhow, when there is a load on it it gets noisy.  Put the clutch in and
it quiets down.  Drive at constant speed it is silent.  Have not tried
your 25 mph turning trick but I suspect it would make noise as I would be
on teh Gas.   

Thanks for the info.  L8R
