Subject: Rear wheel bearing replacement...don't do it like this..
Content-Type: text/plain; charset=ISO-8859-1
I Googled the procedure and found amongst all the write-ups one
outlining doing the rear bearings without removing the stub axle. I tried
to do it that way. I messed up the outer bearing trying to push it all
back together as the Shooftie write-up suggested, using the bearing carrier
bolts to 'press' the bearings into place. This is the first time I've done
a Vanagon wheel bearing, so I admit to being unfamiliar with all the
elements, the amount of resistance, etc. I probably should have 'felt'
the bearing was not correctly seated as I tried to tighten it home...
I used a Harbor Freight 3/4" drive breaker bar with a floor jack handle
as a cheater. It still took two of us standing on the jack handle to bust
loose the axle nut, after bashing it some with one of these nut thingies
and also heating it with a propane torch and soaking it in PB Blaster...
I re-ordered a second outer bearing from Van-Cafe and it arrived in just
over 24hrs to near Portland, Or. In the mean time I removed the stub axle
from the CV, a task made slightly more involved since the wheel was totally
apart (I supported the axle on a jackstand, put the hub back on the splines
and used a bar through the lug studs to immobilize it to remove the CV hex
bolts) I should have done this, removed the stub axle, the first time
around....much better way to get things right. It still took patience to
get the outer bearing 'started' into the bearing carrier/hub....(I don't
have a press) I musta 'chased' that bearing around and round for 1/2 an
hour till it finally 'started' into the seat correctly....and this time I
was careful only to tap on the outer race, not the roller retention cage.
The worn outer bearing that came out has some slightly melted-looking,
galled surfaces on the rollers. The inner one I could detect no problem
areas... Again, being unfamiliar with the tolerances that are 'normal'
it's not clear to me how far gone these wheel bearings were. With the rear
wheel raised and spinning in the air, it was quite 'rumbly' while the other
wheel was quiet. Also I've recently been noticing an increase in wheel
noise at that right rear under firm braking...that is the main reason I
went ahead and did the project...fear that something might be amiss with my
rear brakes. Everything there looked fine.
All in all, not a really tough job, but nasty...with all the grease and
the amount of force involved and dealing with those fiddly hex sockets
inside the trailing arm for the CV joints. Hopefully, this experience
will make the other side bearing job go smoother when I have to do it.
