Front wheel bearings

In regards to a "major" front wheel bearing failure, I know of one. My
father owned a 77 Birchhaven with ~ 85K on it. He was trying to sell The
birchhaven, and had it on a lot (he had "upgraded" to a 74 Sequoia with only
43 K on it).

We went to pick it up, and I was following the coach and observed from a
"normal" distance (I first noticed it from nearly 200 feet) back that one of
the front wheels had a major wobble to it. Stopped checked it out, the tire
was worn rather severely from the wobble. Nursed it home, and proceeded to
rip the front end apart.

We found that one of the front wheel bearings had a cracked race. The
bearing was totally destroyed. For that matter we had a real fun time of
pulling what was left of the bearing out of the carrier.

We believe someone either dropped a wheel into a deep pothole at speed, or
hammered a curb.

The moral to that story is if you put a coach on a lot check the buggers out
and keep an eye on the rig. I am quite confident that we would rather have
put the time and cash into coach he was going to keep rather than sell.

Arch I think you have exposed one of the biggest myths surrounding the GMC
motorhome. I heard the same thing about the Toronados in the late 60's
early 70's, but when I tried to get more information found out it was just
rumors. These bearings are large and very well made. They may seize up and
cause some real problems but we know how to solve that problem. Only
install bearings with at least .095" of axial clearance. They are actually
cheaper from Gateway than I could get normal bearings from my local store.

Bottom line. Install the correct bearings, use mobil one grease, install
them by the book.
