Help

I've got a Moser Axle with 7/16" studs on my older chevy. I need longer studs now. I need to remove the existing studs and install new ones.

How do I do this?

I think my studs are "pressed" in but I don't know for sure - they might be threaded in. The other stud holes in the axle are threaded. those are for 1/2" studs I think. How do I know if my existing 7/16" studs are pressed in or threaded in? How do I remove them? I've got the axles out of the car already. I probably shouldnt have done that but I thought for sure I needed a press. I've now seen guys use a lug nut to "pull in" the new stud. Ok, fine, but how do I remove the old ones? And how do I install the new ones without damaging the threads?

The studs are pressed in. I have pounded them out, but it is no easy task. The easiest and best way, is to push the old studs out on a press and press the new studs in.

I usually use ZEP penetrating spray, let them soak and they come right out with a hammer. If you allready have the axles out it may be easier with a press.

IF the studs are pressed in... there is NO 6 sided head to put a wrench on to tighten them in...


press in studs usually have a round head .

The "pull in" is a good way to destroy a new stud. I have done it as a last ditch option (in a autozone parking lot after loosing a wheel) but it isn't the best approach. Pulling the axle and pressing (or even hammering) them in from the back will do less damage to the new studs.

great information guys - thanks.

I'm pretty sure they are pressed in. I will call Moser today and ask them (some guys on the phone over there are clueless but others are good). I also noticed grease under the stud head as another clue that they were probalby pressed in. And yes, they have a round head - which also means they were pressed in.

So having said that - I took a 5 lb sledge hammer and gave a good whack to one of the studs. It didn't budge. Didn't even move a bit. So now I'm scared I'm going to screw it up. I think at this point since the axle is out I will bring it to a shop and have them press them out, and press in the new ones.

Do you guys agree or is that going overboard?

With the brake drum off ... look behind the axle flange ... or run your finger around the back side ... if the studs are pressed in ... there will be a very noticeable shoulder to the stud ... that keeps the stud from coming all the way out. ( see photo ).

I have found that in the long, it is easier to just go ahead and remove the axle shaft. It is only 4 bolts. I then press the studs out on a hydraulic press ... and then install new ones. But I do have my own hydraulic press.



Like Crosley said ... if there is a 6 sided head that a wrench fits on ... then screw them out.

If it's already out and a 5-pounder won't move it, I'd press them out for sure. And since the axle's already at the shop, and the press is already set up................

You did bring the new ones with you, right?

I think my Moser axles have an ALLEN head stud in them.
