<VV> Re:GRINDING NOISEs

[N2VZD at aol.com]

the intermittent grinding noise in my rampy, that sounded ;like the left rear 
or differential turned out to be the right rear axle bearing. i jacked it up 
. put the jack stands under it , ran it about 45 - 55 mph for about 5 minutes 
before it showed its ugly noise. it was still not extremely clear exactly 
where , but after pulling the axle and feeling it..i was a happy camper not to 
have to pull the engine right now.  spare bearing has been about 500 miles now , 
sounding just fine. winter will bring more attention to both rear bearings , 
plus the front ones. the plan is to pack all with that magic amsoil red 
synthetic grease. any comments on this idea?
