One of my rear spindles got stripped earlier this year but it was after the bearing froze. I can't recall Jeff at Alex Sirrum mentioning it as a failure he'd ever seen. One day he and I went sailing on Lake Okeechobee and I got him to think through every odd GMC disaster he'd ever heard of. That one did not come up.

Carl, those rear spindles are overengineered by at least 100 percent. The
only ones that I have personally seen were failed because of failed bearings
due to too long an interval between repacking, or too tight an adjustment on
the roller bearings. If you clean and inspect the bearings and spindles,
replace the seals, and repack with synpower grease by Valvoline, you should
be good to go for a very long time.

That surprises me that Jeff has not seen it.
I have helped at least three GMCers replace their spindle after the bearing froze and either broke or exited the wheel. Then the wheel runs on the spindle threads for a while until the wheel falls off. This grinds down or strips the threads and requires spindle replacement.
The last one I worked on was Kerry Tandy's when he lost his wheel near the west enterance of Yellowstone on the way to a GMCWS rally in Cody, WY.
I had to find bearings locally and drive my car about 90 miles each way to and through Yellowstone to reach his GMC. I had a thread file and I was able to file the threads enough to get a new nut onto the spindle so we could get back to the Cody campground where we could get the spindle out and replaced.

Emery -- I probably wasn't clear. I'm sure Jeff has dealt with frozen bearings causing the spindle to strip, that's what happened to me. The original inquiry was about whether a spindle could simply fail, not a failure due to a different cause such as a frozen bearing.

G'day,
Wasn't there a service bulletin from GMC on the spindles? Or was that the
bogie pins?

Greetings:
I am curious to know if anyone has ever had, or heard of someone having, a
rear wheel spindle failure – I know there have been rear wheel
“spindle bearing” failures for various reasons, but I am curious
about failures involving the spindles themselves.
The reason I ask is that while I have my ‘bogies’ off/apart for
some R&R and upgrades, I was wondering if there was any need to have the
spindles get some NDT (non-destructive testing) using Dye Penetrant /
Magnaflux / X-Ray.
But if there have been no reported/known problems with the spindles,
I’ll just Dye Penatrent check them for no other reason than
“because I can” :d
Thanks for any information you may have.
Carl
