Replacing wheel studs on the rear axles of a ‘46 1/2 ton. Research shows 1/2-20 x 1 63/64? The studs I pulled from the axle are 7/16-20 x 1 1/2. I know that someone, somewhere has been into the rear differential. Did they replace the rear wheel studs with an incorrect size? Appreciate any information.

"it's only old if you can't find a use for it; otherwise it's cool and i'll use it."
Can’t say for a ‘46 but I can say for sure my ‘37 is 7/16x20 and it hasn’t been messed with except a couple replaced at the machine shop because some PO King Kong snapped them off.

Ed - A quick swing through GM Partswiki shows your rear wheel studs should be 7-1/6" - 20 x 1-7/32". The 1/2" - 20 x 1-63/64 ones are listed as 3/4 and 1 ton truck wheels studs.
