if I remember correctly ..
going back together ....I get the stub axle inserted/pressed into the
housing thru inner bearing and seal ..
then I pretty much fill that housing area with my preferred grease (
probably more than most people or the book says to use..but I have seen
dozens and dozens of dry CV joints and bearing housings and bearings on
vanagons ) ..
then put the spacer in,
then the inner bearing and seal.
In no case ever has there been an issue about putting the spacer through
a hole too small for it.
as far as I know..there is only one version of 'Vanagon rear axle
housing' ..
whether air-cooled, diesel, waterboxer, Syncro etc..
from 1980 to 1991.
at least every one I've ever touched has been the same.
I've found it to be a potentially very tricky job ..
using a ( cost like 100 bucks at a discount tool store
..made in Taiwan ...about 25 yrs ago ..handy inexpensive Shop Press to
have around ) ..
I've had the stub axle get a tiny, tiny bit cocked, causing a problem
, and had to back up and start over.
I've seen it hard to get high quality bearings ..
like I say 'not from you know what country' and they still send those ,
lol.
I've read about guys on here replacing the rear bearings and having they
go out in a short while ..like months ..for no reason.
So do very, very careful work ..
it might even be worth it to have a machine shop do the pressing .
Done right with quality parts and good grease...
it can last 10+ years like the originals did. Many in use are still
original I suspect.
That's another Great Thing about Vanagons ..
you almost never think about Wheel Bearings ..
even if the fronts, for example, never get checked or serviced in
decades....just amazing.
it's always a fiddly job I think ..
requiring patience and careful work.
