Just finished posting both the Radial/non-Radial Wheel and CV Joint
pages on gmcmotorhome.com...
Dave,
You may not be too far off. While going thru the stuff I had written on
the CV joints(I ashamed to say how old it was), I added GM's
instructions on packing the joints. You're supposed to fill the joint
and the folds in the boot - no more. Zeb Frady told me when he sold my
father the outer CV boot kit that it might have three packs of grease
and to use only two. Any more and the joint would leak. The kit did
indeed have three packs of green grease in it, which I promptly threw in
the trash can and used synthetic. Too much grease and the pressure
causes it to squeeze out. I don't really know if grease in the groove
is the problem or a symptom - those that pack in too much grease would
have a tougher time keeping it out of the grooves.
Too much thinking for me tonight. Like Arch, I'm going to bed...
