SC Rear Axle Seal Bearing Replacement ....Long Po

Posted by Skycarp on March 10, 2007 at 17:42:35 from (206.81.147.17):

I just finished replacing the inner and outer axle bearings and
seals on my Super C, as part of the restoration project I have
been on for months. I have to tell you, there are some issues
that a first timer has to be aware of.

First off, don’t think you can get away with only taking out the
inner bearing and seal. You have to remove the outer seal
retainer and remove the outer bearing. The axle will not slide
out of the axle carrier due to the center part of the axle being
larger then the inner bore of the outer bearing. And, the buildup
of sludge, old trans oil, and just plain ole dirt in the axle carrier
needs to be cleaned out too.

The steps I took to reinstall new seals and bearings are as
follows:

New inner seal pressed into the axle carrier. The inner seal can
be damaged easily when inserting it into the axle carrier if you
do not have the correct size seal pressure tool. I suggest using
a pipe type tool rather than a blunt type press tool. I damaged
the first seal using a blunt tool. Also, the lip of the seal faces
toward the chassis.

Next insert the inner axle bearing into its carrier space. I had to
use mild pressure for this insertion. This is a roller bearing so it
takes a little pressure to seat the bearing.

Next the axle was installed from the outer end of the axle
carrier. The pressure of inserting the axle through the bearing
is likely to push the inner bearing out of its carrier space. I had
to put the axle carrier in a vertical position with the spline down
on the floor over a piece of short pipe that fit over the axle and
onto the bearing race. I drove the axle through the bearing with
a dead blow hammer till it was home, all the time being careful
to not damage the inner seal surface with the axle.

While still in the vertical position over the short pipe, I drove the
outer bearing over the outer end of the axle into its carrier
space. This may or may not be and easy job. My outer bearings
were a tight fit in the carrier so I had to use a large blunt punch
the size of the space between the axle and the carrier so I could
make even contact with the inner and outer bearing races at the
same time. It took a while to get these bearings home. They
have to recess into the axle carrier so the recess on the outer
seal carrier can fit into the axle carrier. I would recommend that
you not rely on the four bolts of the seal carrier to do the work
of seating this bearing. It is likely you will strip or break the
bolts. Take the time to drive the bearing all the way into its
machined carrier before installing the outer seal carrier.

Hope this helps someone else. If I missed something feel free to
add to it.
