Looks like I tried a good one this time. Bought a "parts only" Bosch front loader. No mention of problem. Fired it up. Mild thumping then loud thunk. Washed the clothes great!. Looked inside top and found one counterweight on the bottom and a mounting chunk of the front drum broken off. Need a service manual to properly take it apart and then I need a source for reasonably priced front drum. Thxk
