crenwelge (Kenneth),

"I just lock them in high range, . . "

That is what I intend to do with my 54/55 GMC 2-ton COE.

Am I correct in my understanding that the "default" range is "low", and I should mechanically lock the rear into "high" back at the rear-end (where the vacuum-switch unit makes the "move" selection)?

Thanks,

Tim

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
