Subject: Doughnuts, donuts, bagels and giubos-

["George" <lag@domain.elided>]

In AD7-1094 Scott Corsaro asks "Are the Italian's the only people who use
the
doughnut in the drive shaft? - - -  What are the advantages of a doughnut
over a "regular" drive shaft?"

Post 1996 Land Rover's use a "rotoflex coupling" in front of the rear
differential. When they started importing these vehicles into the US in
numbers, there was considerable protest over the amount of slop in the
drivetrain and the "clonking" noise it generated. LR responded by replacing
the standard u-joint with a guibo. These generally work well for street use,
but they don't hold up as well in serious off road use or towing situations,
especially if the vehicle ride height has been increased. According to the
LR lists, LRNA will replace a defective rotoflex coupling with a u-joint if
the customer requests it and its under warranty.
