Morning All,
Have any of you come across a good solution to problem of hydraulicing
(spelling?) in the prop shafts?
Just to explain - the front and rear prop shafts comprise two halves
that slide in and out of each other when you go over bumps. You keep
the join lubricated via a grease nipple on the proshaft that forces
grease between the splined shaft that links the two halves.
The hydraulicing problem comes in when you pump the grease into the
axle - it effectively acts like a hydrualic ram forcing the two halves
apart and putting pressure on the transfer case and the diff. This
would explain the problem of worn output shaft bearings I have seen on
some people's transfer cases.
I have just removed my rear propshaft to replace a worn UJ and am quite
staggered at how much pressure is require to move the two halves back
and forth. Which is worrying when you think of the forces being
applied to the transfer case and the diff everytime the axle moves
(shortening or extending the propshaft).
I guess a lot of the problem could be down to old grease so will be
giving both halves a thorough clean out, but would be interested to
know if any of you have come across any clever solutions.
Certainly in the future I will be adding a strip down, degrease and
then regrease of prop shafts to any vehicles I'm prepping.
