Re: 91 XJ: front driveshaft double-cardan lubrication

Yes, I was a mechanic in the Navy until Pearl Harbor, took me
twenty two days to die.
This life, I rebuilt my first carburetor at the age four, drove
twenty five dollars cars on twenty five cents tires, which of course
needed a lot of work to get to school. Caught the hot rod bug in high
school: http://www.----------.com/dragster.jpg Did twenty years as an
owner/operator Chevron Dealer: http://www.----------.com/chevron.jpg and
burned out, and thought Sony and Will's characters had a good job seeing
the U.S.of A. So I became an independent trucker driving a million miles
with two logs. Doing normal maintenance took all my spare time, giving
me a bunch more mechanic experience, but not much fun at ten cents an
hour: http://www.----------.com/kenworth.jpg
I was surveyor while in the ARMY '64 to '66, and tested all the
artillery divisions and the Honest John missile in Germany:

I'm not as talented as Bill. I find I have to detach the front shaft
from the transfer case to get the grease needle to the socket ball.

Re: 91 XJ: front driveshaft double-cardan lubrication

More precisely, in the differential, the 'spider' is comprised of the
two 'spider gears' and the 'spider cross shaft' that pins them to the
case. The other two gears, the ones on each side connected to the ends
of the axles, are called 'side gears' or 'end gears'. The 'spider' gets
its name from the way it can crawl around on a side gear just like an
arachnid doing a 180 degree turn.

Re: 91 XJ: front driveshaft double-cardan lubrication

Bill, I noticed your Chevron station was near (or on) Foothill Blvd. Is that
the Foothill Blvd. that runs thru Sylmar, Sun Valley and near Mt. Baldy? Why
did you give up on your Chevron station? It looks like your station was a
full-serve. I always thought there was a lot of money to be made in
automobile service?

Was that pic of the Pomona dragstrip? I think that's the only dragstrip left
in Southern California now.
