Did the WWII Willys jeeps have a 1 piece hub and drum?I have seen a pic of one with the Ford F script.

All the parts lists for the MA/MB/GPW/GPA show a hub & Drum Assembly Kelsey Hayes LT> KHW# 25647 (GPW# 1103) (WO# A1689) 2 EA and RT> KHW# 25646 (GPW# 1102) (WO# A1690) 2 EA. But the same manuals also list a Hub KHW# 24659 (WO# A1691) 4 EA and a Drum KHW# 24566 (WO# A472) 4 EA separately. The drum is attached to the hub by the 5 wheel mounting studs. To separate the hup/drum you must drive the 5 studs out then install new studs during reassembly. Note: the drum is inboard of the hub.

This differs from the postwar jeeps like the M38 which positioned the drum outboard of the hub and retained it to the hub with three 1/4" counter sunk screws.

Since you posted this question under the M100 trailer board:

The MBT trailer used the same hub/brake drum.

The drums were also swedged around the wheel studs. Some guys will take a hole saw and cut the swedge area of the drum to release it. They don't just push out like the later civilian ones on pickups etc. You can warp the hub in a press trying to push them out with the swedge intact. Even with good backing. Ask me how I know----
