there are clips that hold the lid down, you insert a putty knife in the gap between lid and front panel and push in on the clips then lift the lid
the front panel has 2 screws near the bottom, remove screws and lift lid, then the front panel slides down and comes off
off balance can be a few things, broken leg on base,broken spring, bad snubber or broken bolt on inner tub trunion
so once front panel is off first thing is a good visual inspection, common friggy problems.... oil leak from trans greeses snubber and causes it to slide too easily, so look for oil
another i see alot of is the broken bolt on the inner basket trunion... to test this you grasp the top of the inner tub and rock it. the outer tub should move with the inner, if the inner tub moves more or feels loose you need to remove the agitator and check the 2 bolts under there
btw, if it is that bolt broken you can replace it at any hardware shop, BUT make sure its a galvanised or stainless bolt or it'll rot in no time
