Full Float Rear Axle Help

[gmac]

1982 FJ45 Troopy with full float rear axle.
Went to snow plow and noticed a bit of grease on the Rear Right wheel. The grease had come from inside the hubcap. When I moved the Troopy I heard a noise inside the hubcap, thought it might be ice. Took the hubcap off and found three of the studs with cone washer and nuts broken, first photo, and also the pins I'm pointing to on the second photo where almost out. The other three studs with cone washers where loose.
Any thoughts on what could be going on.
Just looked at the manual, but can't tell what could have caused this.
Thanks
Guy

Oops, forgot the photos.

There is a thread here or in the 60 section about beefing up the full floater. Believe the issue may be nuts loosening up that causes them to snap off. Also those pins should be flush when the axle is installed. Either a longer replacement or working their way out.

Thank you. Yes, the pins are flush on the other side, looks like they worked their way out. I'll do search on the 60 series. I'm hoping that that is all it is, that the nuts loosened and then the studs broke.

Thank you. Found that thread, that included the following video:

Wheel Bearings (Terrain Tamer)

Looks like I might have loose bearings. Will try to check that this weekend.
Looks like I will be Calling Cruiser Outfitters cruiseroutfit on Monday.

Haven't read that particular thread, but always use 'paper' gaskets and gasket glue vs RTV silicone. I've broken many studs because I thought I'd use silicone.

Yuck, btdt. We've got everything you need to fix it up but the big question mark is getting the broken studs out. Worst case we have complete hubs for the FF but I'm hopeful you can back out the broken pieces. If the hub studs damaged he hub by coming loose, we've had great luck clocking the studs to a new orientation and we have a jig for doing so.

Give us a buzz, I'd love to help you out!

One easy way to remove those broken studs is with a left handed drill bit. The action of drilling them backwards is that quite often the drill willl spin them right out. If they broke because they were loose they might come right out anyway.

Thanks Kurt, just removed the axle and yes, the bearings are loose, so I will be calling you on Monday to order a complete rebuild kit, studs, and the special tool.

Thanks for the tip. Managed to get everything removed. Just so I understand correctly, you run the left handed bit reverse correct?

correct, that way if it catches it will unscrew the bolt or stud.
a right twist, or normal drill bit would catch and tighten the bolt or stud

 

[shawnfj40]

^yup exactly!

 

[gmac]

Yes, probably not my smartest question, but I thought I'd ask anyway to be triple sure. . Thanks for the tip, all three broken studs came out without an issue.
Now to order parts and put it all back together.
Thanks Mud community.

When you you replace the studs, chase the threaded holes then clean meticulously with brake cleaner and dry thoroughly. I’ve started using blue loctite, although some will object to this.

One potential trouble spot. When the hardened pins back out like that, they often wallow out the hole in the hub itself. THen when driven back in, they don't provide any strength. So examine carefully. If Kurt can machine new holes, that's a cool service. might be an economical way to handle this.

 

[shawnfj40]

If the holes aren't oval shaped for the pins I use a good pair of vice grips and redneck knerl the pin so that it will have a little bite when you tap it back in.
