Bosch washer is unbalanced and loud when in spin cycle

SOURCE: Maytag Performa Washer

What I found on my Maytag was the water pump went out. There is a metal ring under the pulley that fell and was grinding until it froze. Replacement is easy and can be done by anyone. You can buy a reasonable pump offline. Good luck with your repairs

There are 2 things you can do.
All washing machines have an off balance shut off, some are touchy, some let it run around the house. With wht machine empty, lean it towards you, on the 2 front feet, about 2 or 3 inches and let it drop. The self leveling feet in the rear must BOTH make good floor gontact and sometimes, just the weight of the machine will not adjust them. The other thing is, make sure the load is evenly distributed. Coats, blankets, small rugs etc. are very heavy when wet and they tend to throw all of the weight to one side.
There is no screw holding the yub in place. It hangs on the center post, where the agitator goes. There is however, what's called a snubber. It is a rubber device that looks like a flattened suction cup, that comes in contact with the tub. It helps keep the tub from jumping around too much.

there is a three post bracket bolted to the back of the inside drum. on ours two of the three spokes are broken. looks like you have to buy whole new drum assembly. around 300 bucks

during transport there are fittings installed to prevent damage to the machine. The shaft may have got bent but before panic sets in try to check 1. that there is a gap between the mahine and units
2. that the unit is leveled.
