Welp....I picked me up another FB. I went to swap a different set of wheels to find a surprise. On the left rear wheel, 2 lug bots were cross threaded into the axle.
I have been debating how to fix this problem. Any suggestions???????

Buy another axle.

Drill & tap 4 new holes in same axle.

Weld a stud to the flange using the stripped holes for location.

Hel-a-coil (sp) I wouldn't do it to my car with my a$$ in the car.

If the threads have been damaged, drill them out and helicoil the hole to give yourself fresh threads. To avoid that in the future and to make changing wheels easier, you can upgrade to screw-in wheel studs and separate nuts.

Okay....Helicoil sounds easy enough. I googled it but not sure how it works. Does it use an insert? If I use Helicoil, could I make it the factory thread? Anyone know the factory thread?

How does this proccess work??....

Sorry, but I just don't have any experience with this stuff...

Thanks guys!!!

IIRC, threads are:

M12X1.5

you can get lug nuts, bolts, studs,etc this thread all day long at auto parts stores.

id switch to studs and nuts as soon as you could.

heli-coils are easy. say you have a stock hole that is the size of a dime (this is just for laymens terms) and its stripped. What you do is drill the hole larger than the stock hole say for instance the size of a nickle (each heli-coil has a specific size need to be drilled for, it will say on the package) Drill the hole, tap it, then you put the heli-coil in (which is just a set of threads) and then your hole will be back to your stock size...done and done.

A heli-coil kit will come with the drill bit size listed, and the tap needed to use it. Most heli-coils use a special tap, since the thread pitch is usually different than the normal pitch of the larger size bolt/nut.
For this application, I'd reccomend using the heli-coil and going back with the screw-in studs. Use threadlocker on the both the heli-coil and screw in stud.

What tipe of diff you swap, drums or disc. drums is the only one the comes with bolts and the one with disc have stud take your disc brake out if is disc one and all you have to do is hit it with a hammer to push back and replaced with a new one, if is bolt with the thread on the alxe go little bigger than 1.5 use like 1.75 for does 2 and tapped is safer then hilicoil.

Sorry bassrotor, but all 1st gens use lug bolts, oem. Disc/drum has nothing to do with it.

Blake

The GSL-SE uses studs. All the rest are lug bolts.

When I did this in my original FB, I picked out a set of studs that had the smallest shank from the local NAPA, and where the right thread, drilled out the original holes, and pounded in the studs. Cost about $25 including drill bits lug nuts and studs, and there is no worry about a helicoil coming out with the wheel on the freeway.

on my trochoid all four bolt was loose due to the wearout and I replace with push in like honda and other car have what holding my wheel is the nut outside not like the rx7 the have the nut in top of the bolt, thanks for your inf,

I have been having a hell of a time finding a kit for M12x15 for a good price. I found one that was like $80....

Any suggestions? I'm going to try Napa tomrrow.

Thanks

EDIT: 31/64 is the drill size....WOOT

Best I could find thus far....

I guess I will let you all know how it goes.

Thanks for all your help!!!

Helicoils are a thread insert. Usually stainless steel. They are actually a wound "Wire" that threads in, and shink to fit the hole as they go in. Once in, they shouldn't ever come back out, especially if you use locktite on them when you install them.
