Hello everyone, Merry Christmas.

I’m needing info on replacing the wheel studs on my 68 c30 motorhome.

Looking for specs on the studs and lug nuts themselves.

Front rear or both? They may be the same, I'm not sure. I have a '67 c30 Cab & Chassis frame that I could probably check tomorrow unless someone has a stud laying loose.

Depends on the GVW on the door tag. These are Dorman numbers..

W 11K rear axle front 610-076.....rear 610-071
W/O 11k rear front 610-185.....rear 610-144



076=.730 knurl, 1-11/16'' long, 9/16 shoulder
071=.660 knurl, 2-7/8'' long, 1.0'' shoulder
185=.560 knurl, 1-7/16'' long, 5/16 shoulder
144=.561 knurl, 2-7/8'' long, 15/16 shoulder

the biggest difference I see is the 11k stuff uses 5/8'' threads and without uses 1/2'' threads. 11k uses a number 611-042 nut (flat faced or flange style) and the 1/2'' nut is 611-016 standard tapered

Awesome information. Having to figure out exactly what the previous owner did to my c30...
This info will sure help me find what it looking for.
