Arch on thing I have learned since owning the GMC is that there are a lot of
myths associated with it. I believe that many of them are caused by poor
PREVENTATIVE and normal maintenance. The Olds toronado drive train is very
very rugged. But like anything else abuse and neglect will break even the
best machinery. Take the front wheel bearings for instance, and this is
based on my personal experience.
Removed the passenger side bearings and found that whoever had installed
them( a long time ago by the looks of the grease) had used some kind of a
punch to drive them on and there were punch marks and gouges all over the
inner and outer race faces. In addition at one time the bearings had seized
on both the hubs and knuckles and I could see where someone had used a sharp
tool to pound on the inner surface of the knuckle. The inner seal was the
wrong one and did not seal against the face of the constant velocity joint
and hence could not keep contaminents out of the bearings. A poor quality
japanese bearing was used.
On the drivers side the knuckle was even worse, the bearings were almost
dry, wrong grease seals, bearing very rough.
When pulling these bearings with the puller they took almost everything I
could muster to pull them off. They are pressed on very very tight since the
interference fit is very high. Without a good quality puller I can't imagine
how anyone could remove and reinstall them without doing damage to the hub.
Bottom line we have two choices. 1) do the maintenance the right way and
enjoy a trouble free worry free trip. 2) do a half-assed repair and worry
and in the end break down anyway.
Thats the reason I am so strong on killing the myths about this coach. Its
a fantastic coach, however you have to have the correct tools, manuals and
knowledge to repair it correctly so it will last. The latest myth, oil
restictors, wallace bearings, mobil 1(don't want to really start a war but
we need to discuss why Mobil 1 may be a poor choice for the 455 that has not
been rebuilt),
