Rear wheel stub unscrewed with wheel nut

[slomo]

I got nail puncture in rear tire and was going to replace with the spare. Jacked tire up and loosened the wheel nut and all the studs where coming off with the nut. Is it OK to add Red Loctite and hand tighten until Loctite sets, or should I get new studs and nuts. How long is Red Loctite suppose to last on wheel stud? I don’t think I was hard on rear brakes to heat them up enough to cause them to heat up Loctite enough.

What???
The studs are usually pressed from the opposite side of the flange (that the wheel sits on). They can't come off - unless they are broken.

The front studs are but not the rear studs.

 

[pmatusov]

Oh wow. I cannot come up with any reason for that implementation.
I already made a habit to smear stud threads and wheel mounting surfaces with antiseize...

If you have the steel wheels with pass-through lugnuts, I'd jam two of them together near the part of the stud that faces away from the vehicle, then use the outermost nut to screw the stud in tighter. Loctite is probably a good idea, too.

Rear wheel stud R&I from the workshop manual:

Remove
1. Remove the rear left Brake Disc. Refer To: Brake Disc Rear Left (Remove for Access and Install)
2. Remove the rear right Brake Disc. Refer To: Brake Disc Rear Right (Remove for Access and Install)
3. WARNING: Do not use the nuts that attach the Wheels to the Wheel Hub for this step. If you do, the Wheel Nuts must be replaced.
NOTE: The nut size must be M14x1.5mm.
Loosely install two nuts to the Wheel Stud.
4. CAUTION: Be careful when you loosen the Wheel Stud. The Wheel Studs are installed to the Wheel Hub with Loctite 278 and are difficult to remove. If you are not careful, personal injury can occur.
Undo the nut that is nearest to the Wheel Hub to loosen the Wheel Stud.
5. CAUTION: Be careful not to damage the threads in the Wheel Hub when you do this step. If you do damage the threads, the Wheel Hub must be replaced.
Turn each of the two nuts in the opposite direction to loosen them from the Wheel Stud.
6. Remove the two nuts.
7. WARNING: Do not use the Wheel Stud again. If you do, the Wheel Stud can break. This can cause death or personal injury.
Remove and discard the Wheel Stud.

Install
8. Use the applicable thread-cleaning tool to remove all adhesive from the threads in the Wheel Hub.

12. Loosely install the Wheel Stud to the Wheel Hub.
13. Loosely install the two nuts to the Wheel Stud.
14. CAUTION: Be careful not to damage the threads in the Wheel Hub when you do this step. If you do damage the threads, the Wheel Hub must be replaced.
Turn each of the two nuts in the opposite direction to tighten them to the Wheel Stud.
15. Tighten the nut that is farthest from the Wheel Hub to torque the Wheel Stud to 80.0 Nm.
16. Turn each of the two nuts in the opposite direction to loosen them from the Wheel Stud.

Thanks for information. I'll consider if I should do take on this task.

I can confirm that the front and rear wheel studs are different. I made the pictures above. The rear ones are screwed in from the outside. Someone here on the forum once had one of his rear wheel studs break off. To remove it, he had to weld a nut onto the remaining piece before he could get it out. For a trail repair, I asked him if it wouldn't have been possible to unscrew the broken piece, for example, with locking pliers. He said no. According to him, the bolts are so firmly glued in the wheel hub that they can't be easily unscrewed. That's why it's strange that all the bolts came loose when the wheel nuts were loosened.

Someone at the factory had an off moment?
I carry a small gas torch, uses of which include melting threadlocker.
@slomo were the nuts rusted onto the stud?

Instead of red, go with orange.

Take it to a workshop they will have the tools and skills to check the hub threads. Assuming the studs where correctly installed at the factory there can be the chance the wheel nuts have been excessively over tensioned multiple times. Cast steel or iron housings are easier to damage the threads in then a housing that was made from a billet.

They looked ok, but it was all the studs on that wheel

Sounds like good advice. I've rotated tires several times with no problems before.

That’s a good find @Clark Kent thank you. Which section of the workshop manual did you find it in? I’ve been looking for it on and off for a few months with no luck. Also have you managed to find a matching procedure for the front wheel studs?

Cheers

I cannot see an equivalent topic for the front wheel studs. The information is not in the next higher assembly front hub R&I topic either.

The front wheel bolts are inserted from the rear until they reach the knurling. They can then be driven in with a hammer until they stop. However, a more elegant method would be to slide a pack of washers or a small piece of pipe onto the front of the wheel bolt after inserting it from the rear until it reaches the knurling. This acts as a counter-bearing. Then, a standard M14 x 1.5 hex nut can be used to pull the bolt in until it reaches the rear stop. The stop should eliminate the need for any special torque, especially since the wheel nuts, tightened to 160 Nm, will then tighten the bolt automatically.

Remind me please. Can this be done with the wheel hub installed? I have a memory that the stud is too long to be removed or installed with the hub mounted.

 

[Greasemonkey]

That's right, if I remember correctly, TomD had to remove the wheel hub because the wheel bolts were too long. However, that doesn't change the basic installation procedure for this type of bolt.

I knew how to install and remove the rear bolts with the locknuts, but I didn't know they had to be tightened to 80 Nm.

I'll add a note to my spare rear bolts.
