special needed, other than a hydraulic press for the bearings, that a
home machanic should be aware of? TIA
Hi,
You can get away with "regular" home mechanic kinds of tools if you
don't mind being a little creative. For example, a hydraulic press isn't
absolutely necessary if you make a "press" with some heavy threaded
stock, nuts and many washers for pressing the bearings into the housing.
If you're REALLY careful, you can also drive the bearings in with a
hardwood block (pressing's best, of course!)
You will probably have to be a bit innovative getting the stub axle
pulled far enough thru the hub that the main axle nut and washer can be
used to finish the job. (Watch the final torque spec--go over rather
than under if you must to get the slots aligned for the cotter.) Short
bits of pipe can be helpful as spacers. Other than that, take it slow
and easy, and with a bit of care you should be fine. Also, don't skimp
on bearing grease, and be sure to use new grease seals. You see lots of
posts about Subie wheel bearings--there are lots of "causes" mentioned
for failure, but if well greased, and properly sealed to keep moisture
out, bearings SHOULD have a good service life.
Also, the roll pin that holds the inner joint to the trans is a one way
fit: the holes are tapered, so if it only goes a little less than half
way in, stop, drive it back out, move the outer shell 180 deg on the
inner splines, and reinstall the roll pin. It shouldn't be too hard to
drive in--excessive force says something's not lined up properly.
Good luck, and ask more questions if you get stuck!
Rick
