And in a double-triangle pattern, which a swear I saw in the WSM but can't find right now.

It is a bit of a gymnastic effort to torque the bolts and counter-hold the hub by yourself. A second set of hands is nifty.

A specifically modified/constructed bit is also useful.

Along with loosening the mid-exhaust to enable access.

Other that, yup, getting the bolts past new boots and through the holes is an art.

I’ve never had any back out and I sure didn’t waste tons of time trying to get all the grease out of the threads or the holes they screw in to. Like said above, torque them properly and there will be no issues.

to have the hub stay in place while torquing,
a third man can be had,
use a thicker shafted 8 inch screwdriver placed into the rotor, wrap a turn or two of tape around the shaft so it wont slide out.
this will hold against the caliper then the shaft wont turn

parking brake = too many cycles of ,
open and close the door,
get up off the ground and get back down .
release and set the brake,
walk to turn the axle. BTDT

Screwdriver in rotor is the quickest way to finish this job.

Long crowbar stuck through studs.

Wow... I've exceeded Greg's standards for a change.

I picked up going the extra mile after working on 944s where it's a more common failure. Those use a smaller bolt and only 42nm of torque. On the 944, I've checked up my own work, without all the prep, and the bolts weren't torqued fully.

Ive done this tedious dance a few times. Never thought of the screwdriver trick. I’m slapping my brow now!

Some time ago, I acquired a semi truck tire iron. 3' long or so.

I never quite understood why, but there's a notch in the shaft near one end. I found out that I can hook that end over one of the studs and the notch lines up perfectly with the stud on the other side. The other end goes to the ground and it holds the axle in place.
Perfect for tightening up CV bolts or even the axle nut on the 944.

Something like this:

You guys are amazing. Had a bit of time this evening so went under the back. There was grease on the bolts, hub, but the metal cap on the end of the CV joint was intact (though slightly out of alignment with the holes) I wonder if the PO put grease on the outside of the cap (why????).

Anyway, cleaned up the holes, and screwed in the first four bolts. Will do the rest this weekend, then that should get me back underway. One step at a time.

Question: Is that an allen bolt or should I get a larger star bolt socket?

This thread got me all paranoid since I haven't look at these bolts since I changed CV boots a couple of years ago. So before heading out yesterday I crawled under the 928 and verified the 8 or 9 bolts that I had immediate access to. No problems
I added retorquing these to my list of things to do next time the rear-end is up in the air.

8mm Allen: Good I have snap on versions of those. They never gall or slip, so a simple job.

This is a just-in-case reply...

.... if it's difficult to tell from looking at the bolt if the socket-head is Alan, Torx or XZN then it's time to replace it.
