You can't be too safe! I speak from experience on this one. I bought #5761 in 1993 - after a couple thousand spirited miles one day I heard a load bang!! Did not know what it was until someone behind me signaled to pull over because I was spraying his windshield with gear oil! I was lucky, one bolt head flew thru the oil pan and 5 more were in the pan. The ring gear was still tight but I was seconds away from total ZF destruction. I installed new factory serrated ring gear bolts with Loctite and left it for 10 years until the major restoration. At that time I asked - "I wonder how the red Loctite is holding up after swimming in gear oil all those years?" Yeah, for peace of mind I changed the bolts, used Loctite and safety wired them. I don't think about the ZF at night anymore! Ed

when Loctite thread locker will do the same!

While I understand the ease of Loctite in comparison to safety wiring, to say they are the same just ain't so.

IF there was a magic fluid that was "the same" as safety wiring, I imagine we would cease to see racing machines, airplanes, etc using safety wiring.

Until that happens, I vote for safety wire.

But if the thought of a backed out bolt having its head snapped off only to see it become wedged in a spinning gear, causing your ZF case to crack, along with whatever else happens when such catastrophe strikes, doesn't put financial fear into your thought process, then go right ahead. Wink

OK fella's,
This is the kind of info I am looking for:

I talked with a well renouned Pantera Shop and he said the red locktite would work, that's 272, it does not back out.

He also said that he basically uses the stock bolts and drill's them if you go that route

These bolt's in case you never knew or don't have measuring tool's are;

M10 x 1.0 x 22mm/.875"L 10ea

The closest I find are in the ARP catalogue but are .050" shorter,

ARP

High Performance series is rated at
180,000 psi, and the premium grade Pro
Series, originally developed for NASCAR
Winston Cup competition, has a 200,000
psi rating.

ROVER

K Series (8 pcs.) .826 M10 x 1.0 206-2803


Larry, your's appear to be drilled stock Items & did you loctite them also?

Ed, do you remember any being loose when you pulled them that were loctited only?

I'm leaning towards the ARP if I replace these.

When I went to replace my factory bolts, the head snapped off the first bolt. Looking at it you could see there was just a sliver of metal holding the bolt head to the shank. The other 9 bolts were loose.

Dennis Quella recommends lock wire and red high temp LocTite. His ARP bolts are special made. You won't find them in ARP's catalog.

Was able to buy the bolts direct today for about $50.00 @ ARP, gave me the kit plus 2 loose,the application is for a flywheel, the flywheel and differential are both sheer loads.
I will drill the bolts myself & get some safety wire from the parts store or McMaster Carr

Here's what I found;
Pantera Parts Connection, ARP drilled for safety wire $285.00

Precision Performance, $110.00

Wilkerson, drilled stock bolts approx $85.00

Pantera International: Go to RBT

RBT: Did not return call

Hall Pantera, They have there's made? $65.00 with gasket & wire, Probably best price but make and strength unknown.

Drill my own, Free!

ARP: 200,000 psi rating, I drill & safety wire, $50.00 to $60.00 shipped.

I'll write this post when they show up to let all know how it went.

Drilled holes easy on a Mill,all went well till the last one, were I broke the drill in the hole breaking threw to the other side. It gave me fits for about an hour, got it out and all is well. Had installed and marked each bolt prior to drilling to get the best location of wire hole as possible, all but one were where I wanted them. Don't think I would attempt this without a mill.
Assembled Ring carrier and axle shafts,
