I heard Wallace is out of business but noticed the new Caspro catalog has a
three bearing hub assy. listed, complete with grease fitting. I am not sure
if it is identical to the Wallace hub.

I'm trying the Mobil 1 approach before I spend that kind of money. I've had
good results with synthetic oils so why not grease?

Any one know why some light aircraft seem to eat up wheel bearings? It
seems I have bought dozens over the years and yet can't remember ever
replacing an automotive wheel bearing. Can a factor be aircraft and
motorhomes tend to set in the same spot for long periods of time instead of
being used daily? Don't know, just brainstorming.

Justin,

I hate to be the one to tell you this, but if your right center wheel is
wearing worse than the others, most likely you've clipped a curb
somewhere along and bent that bogie. Real common problem with our
coaches. That right front bogie gets a lot of abuse. I know that JimB
has the tools to fix - kinda scary, but they use a "portapower" to bend
the arm back into place.

BTW, Chuck Stoddard of Caspro did a _great_ tech session on suspension
and highway stability. Answered a lot of questions why some coaches
drive better than others.

Oops, there I go again! You're right - since we drive on the right
side of the road, our tightest turns are usually to the right and that
center tire takes the brunt of it.
