RE: JPOR: Re: tcase & flat towing

[Dave Jacobs <DJacobs@xxxxxxxxxxxxxxxxxx>]

I think he decided to disconnect the driveshaft, and he's on his way to Moab
as we speak. I see this email originated on 2/22. That took awhile!

		list,
		I haven't posted for a long time. Two full time jobs have
made my 
		online time go away.
		All you're really worried about flat towing with the D300 is
the rear 
		output bearing which will spin if the rear driveshaft is
still 
		connected. The rub is with the usual D300 hangdown the
bearing is oil 
		starved (since the gears in the oil are not turning and
throwing oil 
		up to the rear output bearing) and will burn up after
several hours 
		of freeway towing. Since Loren has clocked his D300,
depending on how 
		far, it may be that the bearing will get oil. If his case is
on a 
		flat plane, it should be O.K. It might be that for the tow
he could 
		overfill the t.case, enough to get the oil to the bearing.
For short 
		periods, I just tow it. For more than  say, 1/2 an hour, I
always 
		disconnect the rear driveshaft at the pig, and wire it up to
the 
		frame. I and some of my Jeeping buddies have left the engine
idling 
		in gear to the t.case for an hour or two during tows when it
was 
		inconvienient to disconnect the driveshaft.
		regards, as always, jefe
