Rear Spindle Removal

[gary j zingle]

This can be difficult given the combination of a machined
cone shaped fitting between the spindle/boggie
arm and rust.

The combination is what creates the problem.

I copied the puller shown in the GMC service manual
but still was unable to get my damaged spindle out.

My brother came over (front end mechanic) and
showed me how to use a hammer.

With the puller installed and torqued up to give as much
push as possible, the end of the bogie arm is hit smartly
with about a 5 lb hammer.

The direction of impact is like as if you are not even trying
to get the spindle out. The impact is like you are trying to
make the hole in the end of the boggie arm out of round
while the spindle is still in the hole. The rust loosened
and the spindle came out!

Withing minutes he had all 4 spindles removed so that I
could not only replace the damaged spindle but could
clean the connection between the spindle and the
boggie arms in preparation for wheel alignment.

Being a tradesman myself I shouldn't have been surprised
at the difference experience makes, even with something
as simple as a hammer.

Good luck to anyone trying this proceedure. I was glad to be
head drink mixer that day.

I've never had to do this myself, but I thought the way to handle this
was to tap the holes from the backside of the bogie and use a harmonic
balancer puller to push the spindle out - with appropriate hammer
encouragement. I guess you could substitute the OTC for the harmonic
balancer puller.
