Installing Moroso long wheel studs.

I'm installing Moroso #46180 wheel studs in my 12 bolt with Ten Factory axles.The studs are knurled and so were the shorter studs that came in the axles.It looks like from what I have read that I can't just draw them in with a wheel nut as I did back in the day.Is there any way to install these with out pulling the axles?
Thanks

If you had a hole in the backing plate in just the right spot you should be able to thread the stud in from the back side, so yes, you should be able to do it.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Re: Installing Moroso long wheel studs.

OK.I was more questioning the method of pulling the studs through the axle flange.A lot of people think that a press is the only proper way.After more reading I think I should be getting 5/8" studs.The car weighs 4000#s with BBC and 200 shot for 720HP and I may up the spray.Drag radials.Sounds like a few guys have broken 1/2" studs if the car hooks hard.I think I'll get 5/8" studs and remove axles to drill and tap.I just had the car painted
Thanks to all.

Re: Installing Moroso long wheel studs.

Since I don't have a "Press" I bought a "Ball Joint Press", and I have used it for many things besides Ball Joints. U-joints being one. I wonder if you could slip that behind the Axel and pull the studs in that way. I hope this helps.

Ideas are like children: there are none so wonderful as your own.

Re: Installing Moroso long wheel studs.

This stud installer will help if you have to put lots of studs in axles.

It has bearings to deal with the forcing instead of just using washers.

Re: Installing Moroso long wheel studs.

I would upgrade to at least 1/2 wheel studs. A couple of weeks one of the guys that races every Wednesday night sheared off his second set of 7/16 aftermarket wheels studs. This is on a mid-11 second car with probably 1000+ passes running Mickey Thompson DOT drag radials. This is something you rarely see, I think I've only seen it happen four or five times in the 500+ races I've been to, but it does happen, so why take the chance.

I've done this a few times with a heavy duty c-clamp and a socket over the the bolt head.

Thanks to all.
The Moroso 5/8" studs are too long. Look at the Moser stuff. The studs need too match your wheel stud depth or the smooth portion of the stud can be too long, even with the supplied spacers.
Make sure your wheels can accommodate the larger stud to begin with.

Re: Installing Moroso long wheel studs.

The Moroso 46180 is a knurled press-in 1/2 inch stud. You should be fine with them. I'd myself look for the needed size from ARP, they make their own studs and the quality is second to none. Hardened stud rolling is pretty specialized and I'd assume Moroso out sources them.

With stock style wheels, I like the 1" Allstar Racing lug nuts.

With a bunch of washers and plenty lube on the threads, it's easy to pull the studs onto the axle flange. When the head contacts the backside of the flange, it'll square itself.

Do you have the needed hole in the axle flanges for the knurl? Axle flanges are hardened and are a bitch to drill. I've done several using a tapered pin reamer.

Re: Installing Moroso long wheel studs.

Can borrow a ball joint press from Advance Auto, its in their front end tool kit. It will press out and reinstall studs

Re: Installing Moroso long wheel studs.

Not sure on how big of a stud it works on, but I bought a Lisle tool made for pulling studs in. I used it on my 7/16 front studs, and it worked great. I posted about it in the tool and shop forum.

And trying to thread an aftermarket axle is not something I would ask many people to do, it's a pain in the butt. Cold tapping into hardened axles is a tough job. I know machine shops that will NOT do it.

Also, you do not need to run the studs any longer then a couple threads past the end of the nuts? Put wheels and lug nuts on, tighten, then hit each of the studs with a cut-off wheel to mark where to cut, remove wheel and lugs, then REINSTALL lugs nuts all the way down, cut the studs, and remove the lugs nuts. They will "re-cut" or clean the end of the cut/burr as they come off. Then you can put a small chamfer on them.
I know most axles are hardened after all the machining is done.I've already had a problem with breaking studs and it wasn't pretty.My axles have 10 holes on each flange.From what I remember the other 5 holes looked like a different pattern but the holes also looked bigger then the 1/2" ones I used.Time to pull a wheel.I guess sending them out to Motive is the only way to machine for 5/8".
Thanks

Re: Installing Moroso long wheel studs.

I also forgot to mention I have a 400 with a brake.If I ever hit the bottle with the trans brake I would like to know that I had a strong rear.
