Mine too!

not really, just putting mine back together on #30

Axle has been sitting under the car for a few years now. All bolts have grease on them, not on purpose.

once it’s back together, and I spend a few more years dragging on with her on the lift bars, I’ll move her over to the lift and remove them one at a time, clean and torque.

Definitely not the first. I beat him to it. I was SURE I torqued those bolts!

Was it the torque or the supercharger/right foot combo?

A tool that makes this (torquing) an easy job is a 4' 1/2 drive extension. Take the wheel off, torque, done. Easy access to an otherwise pain in the *** job.

place a chalk mark or dab of paint on each bolt immediately after torqueing

Default Me too

I had that happen the first year of ownership. I torqued them and about 18 months later when doing a motor/torque tube removal, I saw they had loosed again. So, I drilled holes in the top portion of the bolts and safety wired them in groups of 2. Done.

That's what my 928 tech did to get mine off and on. Seemed to work rather well too!

Don't put second hand ones in there. Use 930 joints. Cheaper than the 928 and almost identical. I have a thread here somewhere with pics and measurements.

Replaced my boots recently, concerned about this outcome.

Went through something related with a front break caliper bolt on a land rover. One of the old ones with the oil bath front CV joint that turned into a greasy mess. I replaced a wheel bearing. Evidently I didn't get the one of the holes for a caliper bolts clean enough during reassembly. Loctite doesn't work well with grease.

Ended up with the brake caliper jamed in the front wheel in traffic in the rough side of town I wasn't familiar with.

Lesson learned! $50 tow & $195 bolt back on the road.
