[Gmcnet] 100,000 mile (and more) bearing service

[Mr.erf ERFisher]

I bring this up now because:

1  If you have not serviced your front wheel bearings - it has not been done
2  GMCWS and GMCMI are coming and you need to discuss this, there
3  Bdub (give that man $10,000) has us back on line just in time
4  Dave Lenzi ( at Santa Rosa) showed how to get more than 80,000
miles on bearings
5  There are at least 4 ways to service the front bearings ( more later)
6  Knuckle removal, (most recommended), causes major damage to front
end components
7  All of us will have our knuckles drilled for a zerk in the future.

Dave Lenzi has refined the knuckle zerk technique to an art form, go
see his talk.  This procedure was first purposed by our forefathers,
Alex Burch and Wallace;

Dave has refined the technique ( with knuckle / shim modifications,
and technique) so we no longer have to worry about blowing out the
seals when we grease the bearings.

Volvo suggests not servicing the front wheel bearings because more
problems are caused by the service than wear and tear on the bearings.
 I believe this is more than true for the GMC motorhome.

So talk about this at the rallies.  We need a way to drill for the
zerks without removing the knuckle (not very likely). At least, we
need a way to drill the knuckles the next time they are removed for
bearing service.

Lessee, there are 8,000 GMCs on the road, times 2 equals 16,000
knuckles to be drilled ;>)  Big job here
