Twisted Drum
Hello Craig
if the tub isnt sitting square in the cabinet then you have whats known as a twisted drum, this is caused by the rubber suspension mounts going soft, the result of this is the tub wont sit squarly, it affects spin performance,
it is a very common age related problem on Hoovers of this design, but it is a relatively easy job to do, and the parts are still available.
Two tools 1/2"/13mm open ended spanner and a good pair of mole grips and some Molykote DX paste to grease up the parts.
And of course a Hoover Suspension kit
if you need any more help etc dont hesitate to ask
Gary
