VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 '31 Rear End Knurled Threaded Studs

Does anyone have a source for the knurled threaded studs on the '31 rear end housing? I have one that is stripped and have searched online, but I can't find one the size I need. 3/8-24 and about 1 1/8 inch long.
Thanks

Hello Bama31,
A local trailer and axle supply might be of help if you remove the stripped stud for an example. Checking online using "3/8 x 24 differential housing studs", came across: Northern Drivetrain, LLC Spicer 36326-1, Code: SPI-36326-1 $1.99 each, Knuckle Spindle Bolt 3/8 - 24 x 1.312 - Dana 30, 44
You could take a look at that,

Thanks for the info Harrys31coach. I will check that out.

I’m not sure the knurling has much function once the stud is installed. Typically the knurling was done to provide a better grip surface to turn the stud into the housing. I always thought that was interesting because you do not torque studs. You just snug them in the hole. When you tighten the nut that puts the whole stud under tension.

I would look for a stud that has the same length on non-threaded portion. You can always cut both ends to length. If the non-threaded portion is too long the joint will not tighten properly. If it is too short you might get some slight leakage around the threads.
