[Rovernet] Of zerks and things which go bump in the night; spastic 'pumpkin' redux

[Vern Inkspot]

Nice story Lance. And think how much extra stuff you’ve learned along the way! 

Your first sentence is pretty much my first rule of life.

Yours
Vern

The only good news was that the crown gear and all other internals were in perfect shape.   Propeller shaft u-joints; check.  Rear wheel bearings; check.  Vegemite in both glove boxes; check.

What he discovered was I had installed the driver's side  u-joint for the end of the half-shaft which bolts to the brake disc, BACKWARDS!!!!    I was gobsmacked to realize one could even install a u-joint backwards.   As it turns out, the correct Spicer u-joints for the half-shafts (5-178-x) have zerks, and for the Rover application those zerks have to face AWAY from the discs, because the clearance of the 'ears' on the half shaft is greater that the clearance of the ears on the plate which bolts to the disc.   Placing the zerk towards the disc results in the binding of the zerk with rotation of the wheel/half-shaft!!!!
