Subject: Re: Not Downshifting + bearing replacement info
You Volks are the Greatest! Once again I've asked a question and gotten more
than enough info to begin resolving my problem. I'll try to remember to post
my results.
By the way, if you've been reluctant to do your rear bearings yourself, don't
be. All in all it was a pretty easy job which could have been done without any
special tools. I did have a bearing press set which was very handy but I'm
sure I could have gotten by without it. A couple notes to add:
- You can easily pull the hub assembly off the axle shaft with a large puller.
There's no need to remove the axles from the van.
- Once the bearings are off their respective positions on the axle the inner
bearing will slide past the outers position by hand with little effort.
- For disassembly the Bentley says to remove the outer race and bearing set in
order to remove the spacer to get at the inner bearing. The race comes right
out but you'll have to destroy the bearing set to remove it. Also very easy to
do.
- Don't skimp on the grease seals, replace them.
- Make sure the outside of the hub assembly is also very clean before starting
to reassemble. If it isn't you'll find yourself picking up small pieces of
grit with your greasy hands that you don't want to get into the your newly
installed bearings.
- When sliding the hub assembly back onto the stub axle, be certain to also
push on the outer bearings inner race. Otherwise you'll find it popping out of
the bearing and you'll have to pull the hub pack off and reseat the race.
- Once you've slid the inner bearing past the point on the axle where the outer
bearing rides, you can then push the assembly far enough on so that you can use
the wheel hub and axle nut to press the bearing hub on the rest of the way home.
- I should probably note for those that aren't familiar with this stuff that in
order to do this job you have to disasseble the brakes. Consider it a good
opportunity to freshen them up and make sure they're properly adjusted.
Hope the helps somebody.
