Hotpoint Bouncing Around

Hi, the drum has started to bounce around a fair amount, and the front/rear springs on the top of the drum are still very tight. I've noticed that the drum is bouncing on the left side when you are facing the machine, and the suspension seems quite weak on that side. I'm not sure if they can be repaired? if they are hydraulic or spring.

Replacements for the lower half of the units are only £15 each, so I assume replacing them is best.

My questions are....

Do I only need to replace the lower half of each unit? they are the housings and not the rods.

I can undo the nut on the bottom of the machine, but have no hope getting to the nuts on the top rods, where they

connect to the drum. The only access would be to remove the total drum. What do I do? Do I undo the lower nuts, turn the machine back onto its base and then try to lift the drum high enough to pull the suspension bolt free from the base of the machine? then turn the machine back on its side and try to pull the lower suspension unit off the rod?

The thing is like a chinese puzzle.

I love the machine and want to keep it running. In the last year I've fitted new drum bearings, new pressure switch, new door switch, new motor and new door seal. Runs like a dream and washes great apart from the rocking.

Many thanks
