I intended to just tighten the wheel bearings, if they needed it. When
I first got this truck back in 92 and did the first wheel bearing
repack I was worried I'd mess up something with the whole 4x4 autohubs
and went thru the whole thing with the repair book in front of me and
spent most of the day repacking the wheel bearings.  So this time when
I was just going to check the bearings and make sure they were
adjusted I found that to get to the adjusting nut I had to pull some
parts off first.  After 60 seconds I had pulled off all the
"complicated" stuff I was so worried about touching 10 years ago.  By
this point I had the front bearing out to check it for wear and
figured I might was well just repack it all.  It's amazing how easy it
was now that it was the third time I've done it and how quickly it
went.  The biggest amount of time was the time it took to clean up the
old grease off things and repack with new grease.  Never did find
anything really wrong but it was definitely time for a bearing repack,
the old grease was starting to get hard from the high temp, I think I
used the wrong grease last time.
