5/8 Wheel studs

[AWSpinks]

For some reason my 1990 250 with a cummins has 5/8" wheel studs. Has anyone else ran into this?

Those are the dually size studs. So you either have dually axle/hubs, or somebody replaced the stock 1/2" with the next bigger size that fit.

.... Been too many years ..But as I recall .. Dodge made D250 & D300 or D350... D300's were light duty one tons & Were mostly said to be the same MOSTLY as the D250's .. It was said that the emblems were the only differences. But as I recalled the D300 had one ton axles ... SO Someone in the past could have lost their rear axle or wanted a different axle Ratio than they had. SO They could have simplely gone to the Wrecking yard & Got a one ton axle & replaced their axle ..
Maybe..

@PaPitt I think you'll find the 200/300 trucks are 70's and 250/350 were 80's-93.

100 and 150 were more wishy washy. Maybe an early 150 was to denote a 'heavy half' type package. My '89 W100 longbed (parts truck) is definitely a very basic trim/option truck.
