longer wheel studs ?

[wright691]

I am getting ready to put my 93-97 Lt1 rear discs on my 69 firebird . I just need to know if I need to put longer wheel studs in my axles like I had to do on the Ls1 front discs that I have on the front . I have my axles out now to replace the bearings and seals so it would be the perfect time . Thanks !

put the rotors on the axle, then put your rims on, then measure

Considering your 69 wheel stud length was ideal for thinner steel wheels and not aftermarket aluminum or whatever, it's most likely you'll need longer studs.

Thanks guys . Going to take my axles to the machine shop and have them press in the same kind that I used on the front hubs .

You don't have to have them pressed out/in. You can remove with a large hammer, and install with a large hammer....just fyi to save some cash. I did mine on my 68. Just make sure you get the same size knurl, or you will need to drill out the holes for the knurl. I had to enlarge the holes in the axle flange.

Rather than bashing them in with a hammer, you can take a lug nut and some washers and pull the stud into place, just be sure to put some anti-seize on the threads of the stud.

EEK Do NOT do this
when you use a nut to pull the studsin you risk stretching the stud beyond its capabillitys and weakening the stud

did you ever wonder why head bolts and rod bolts are torqed?
Well for rod bolts you will find the recomended way is a bolt stretch guage
we had a guy at work do this to a cust car and the cust came back wondering why something was making a clunking noise in his wheel.
Low and behold one broken wheel stud and nut under the cap
try and explain that one =)

My electric Impact can barely pull 80#. I used it to pull my studs in and 80# just will not strech 7/16 studs. An air impact gun and an over zelouse operator can do a number on them.
I lube the knurle well with bearing grease or Redline asembly lube which i just discoverd and realy like for many jobs.

I am not a big proponent of the hammer method as I always manage to hit things other then the stud head :eek:

Pressing them in is my prefference, either hydraulically or using a small ball joint press.

ASE Master tech.. And that means what? I see more hacks at the dealerships and shops than Ive ever seen wrenching in the back yard. As for me being a hack . Hack on my lug nuts.

I pulled mine in and then whacked them home using my trusty 3 pound, BFFT!!

No hassle at all here and worked fine! I did all 20 of them in like an hour..
