Need help with studs.....
« on: July 15, 2012 - 06:20:13 PM »
....ok, not THAT kind of studs.....I am a happily married man.    :bigsmile:

Needing help on wheel studs.

I am replacing the studs that came with the axles that came with my "new to me" 8 3/4" housing.

Pulled the rght rear wheel from the car today and measured.....seems that I currently have studs that are about 1 9/16" overall, 9/16" is shoulder and the 1" is thread, measured per the Dorman chart here:

The lug nutz I am currently using have 1/2-20 stamped on them.

I want to go a little longer as my rims have thick mounting flanges.  I figure an extra 1/4" length will do.

Ok ,so easy, right?  went to the link here (page 10):

#610-174 appears to be the closest fit to what I think I need..... 9/16" shoulder,  1 3/4" long (a little shy of the extra 1/4" I wanted by a 16th)....and 1/2-20.      But the question comes in around the "knurl diameter".    I used a digital caliper and cant figure out if I shoudl be measuring the actual knurled part or the unknurled section below the knurls, seeing as the stud gets pressed into the axle flange.....and in theory the knurls would squish a little (right?).  If I measure at the knurls on my old ones, I get .671 and the chart shows .668.....Is that "close enough"?

Also, teh other question of the day is what are the tricks for pressing the new ones in?  I have a hydraulic press but I cant fenagle the axle to sit right to press them in....so I was thinking of drawing them in with the lug nuts but I read elsewhere that that stresses the lug bolts....

Need some guidance from those who know studs....LOL

Thanks in advance guys!

You should be fine with the knurls , I set the axle on a block or tube & drive the studs in with a hammer
