Hi all,

New guy here

I just purchased new (second hand) uprights with extended studs which are also new. My question is should they be loose? A few of them i can wiggle with my hand and as I've never installed aftermarket studs Im not sure this is kosher.

Thanks in advance!

 

No, they should be pressed in tightly.

 

+1 to Bob. You should have to use a press or well supported BFH to get them in and out of the hub.

 

Should be tight. With any luck, they may just not be installed correctly. Could be an easy fix

 

I ended up replacing them all, not worth the risk. Although the fact that I had to have the hub pulled off the upright to replace them is a bit silly. Ah well, I'll sleep better at least.

 

General info for anyone doing this in the future:

Shouldn't have had to pull the hubs. Insert stud into hub from the back side, line up the splines, put a nut on the stud & then use an impact gun to pull it into position.

 

I tried my damnest to do it that way. The worn out ARP lugs that were in there came out the back easily with a little persuasion. But the new ones I ordered were in no way going in without possibly damaging the lug. Maybe there are different ARP part numbers with the same diameter?

 

I wouldn't think so. Could put 'em in the freezer & lube 'em...&/or heat the holes in the hub. @ minimum it is a metal to metal fit & wouldn't surprise me to find that it's an interference fit. They're in now. That's the important thing.
