Okay time for an update on the rear axle, which is good news being that its one step closer to being on its wheels. So when starting all this "put race wheels on a street car" thing started i knew i would have to change out the studs for larger ones. Not really because i was afraid of breaking the stock ones but because the AERO wheels i want to run on this thing require a larger stud with 45 degree lug nuts. More about that later... First off i wanted to tackle the rear drums and because the car has been stripped down for so long i had forgotten how the rear brakes went back together. But after sitting for a while with the rear brake kit i got that sorted out. Before:
After:
So once all that was done (and go figure ive lost my brake pliers) i went on to the axles themselves. I got a kit from speedway motors to do the studs which included the correct size drill bit, the studs, and the lug nuts i would need. I first pressed out all the stock studs which was easy with a ball joint press and thats when i realized i had a problem. My realization was that i had no way to keep the drill straight when i drilled these holes out. A drill press would have helped however the axle itself seemed to hit on mine no matter what orientation i put it in. A google search revealed that it seems common to wing it and free hand drill them with varying levels of success. The main issue was that if i drilled the hole off angle the stud could push in at that same angle and even 1 degree at the hole could mean that my wheels would not go on to the tip of the 3 inch long studs. So i decided to make a jig for it. I know that from center to center on the holes of a 5 x 4.75 is 2.792 so i did some measuring and found an aluminum block that would work. I used a carriage bolt on one end that seated into the aluminum so that it wouldn't turn. This would be how i would clamp it down, and at the 2.792 center point i used the drill bit from speedway to drill the correct size hole through the block that would be my guide. i had to grind a notch in the side to clear the round area in the middle of the axle flange.
After the block was finished it was time to put it to use. For each hole i would use the bolt to line up through the stud hole next to the one i was drilling and using a nut and washer from the other side i could clamp it down. Then it was a simple matter of drilling it out to the correct size and moving on to the next hole.
So after all the holes were drilled out and the burrs were removed it was time to start putting the studs back in. I've seen some nice tools for installing studs before that pull it through using a lug nut but i already had my ball joint press so i put that to work instead. After lining everything up they pressed right in and just that easy i have some new straight studs for the wheels to go on. Its a small step but its a big win for this project.
