w828 air trap fastener?

Hi guys!
Thanks' for the advice. I'll give you some update on what is happening. The machine past 10 yr mark in Aug.2011, so the only option left is to try to fix it. We already spent nearly 1 grand on new controller and inlet valve (learnt later about cheap poor quality relay on the controller), valve was replaced with no labour charge only material as we complained. At this stage i have drum removed from the machine. I found that 2 bottom shock absorbers are absolute joke- it is just decoration as pistons are moving freely inside tubes- no resistance whatsoever, got a feeling that this induced problem with the inner drum.
I'm going to pull bearing housing, and remove the front of the outer container to see the spider. I have a question about couple of fasteners- one is on Air Trap attached to the front of the outer container through rubber seal and some kind of plastick fastener which looks like miniature baby pacifier, the same kind of fastener is on suds inlet also attached to the front of the outer drum. How do you remove those fasteners without braking it? I have to try to fix this washer before dumping it as we have matching dryer and nothing on the market to match. Thanks' again for your advice-Happy New Year!
