How to stop drum wobbling

The boot will tear if the drum bearing has excessive play.

the only way to do this is to take the top off and push the drum to the rear of the machine and use a stubby screwdriver to loosen the two or only one of the metal clips that keep the flange in place retighten and bobs your uncle it should be done without an expensive engineer callout charge eric

Check the little holes around the drum, I have seen pins and needles get stuck in these and cause lots of damage. I would replace the seal.

You have more serious problem than just your drum seal. The support arms in the wash tub are broken. The wash tub should always spin true. When it wobbles it is a sure sign that the suport arms or spider arms are broken. It is an expensive repair since the wash drum, the outer plastic tub and the door seal need to be replaced. Check your warranty, to see if some of these repairs can be covered. Get a few estimates before deciding whether to repair or replace it. Sorry.

Few things to check as the gap tollarance between the drum and rubber seal is small. Open door and turn drum by hand. Look carefully and see if the drum has an uneven wobble which is touching the rubber. If it has, you need to send the machine back or frplace the drum. Sometimes the rubber is installed slightly off centre which alters the correct rotation gap. Seal would need to be removed and realligned correctly.(I would check the drum for any signs of not being truly round)

I'm assuming you mean the flexible rubber between the door and the drum. Can it be replaced? The short answer is no! However...
I recently repaired a door rubber with a tear that caused the water to flood onto the floor. Here's how:
Yes, you can open the front to get to the door rubber however the rubber seal is glued to both the door and the inner drum lip.
You may have to tilt the machine on it's back to remove three screws from the underside of the front lip. (I forget if you need to take the water pump cover out as well but it wouldn't hurt to do so.) This allows the front panel (including door) to drop down a quarter inch or so and be eased out a little.
This allows *better* access to the drum rubber. To repair a tear - really the only reason you would want to do this - you need glue and some tape.
The door rubber is silicone and will stick with normal 'super glue'. However, bear in mind that these machines can do a wash up to 95C, which is hot enough to soften superglue.
I found a new version of superglue called Repair Extreme by Pattex that copes with temperatures up to 120C. It sets in about 5 minutes.
The glue needs to be flexible. Do not use epoxy resin.
I gave the glue some form by sticking a 10-15cm piece of duct tape - the silver shiny plastic tape plumbers use, readily available from any hardware and most supermarkets - to the *back* of the drum rubber. It's a tight squeeze to get your hands in there but it can be done.
Take the tension off the drum rubber by moving the front panel roughly back in place.
Then squeeze a generous amount of glue along the tear (about 3cm long on the bottom edge; a typical problem) to completely whet the edges to be joined.
Apply a little pressure to the location of the tear for a few minutes to help the glue hold fast. Leave the glue to set for at least half an hour before reassembly.
If you can source a replacement drum rubber the old one can basically be removed by force. A good cleaning and then a suitable glue could stick a new unit in place. However, if this is required, seriously consider buying a new unit. It is difficult to make a good seal that will not leak and may not be worth the effort in the first place.

You would need a special adhesive glue made to withstand the heat! But I wouldn't try. Not even Red Green's Duct tape notion could bail this issue. You would have to replace the complete seal. And that...you're probably looking...around $30-50.

It’s caused by gradual wear and tear through the vibration of the machine and rotation of the drum. If they are breaking down too often then it may be that your washing detergent mix or use of bleach or how you clean the bellows is weakening the rubber. Also excessive and heavy loads put more stress on the drum and can cause the drum to lurch dramatically from side to side which will end up in causing the bellows to wear / tear.

We had the same problem, I printed off the solution posted by john_in_erie. His repair directions were VERY acurate, however we find a few helpful additions to the repairs - 1st in step #6, the spring loaded wire, is in the front of the gasket under seal (we were looking on top of machine). Also in step #8, you need a short phillips screwdriver or a 7 mm socket with a 1/4" ratchet because of the position of the screw to get around the edge of the tub.
Thank you so much John, we could have not done it without your very accurate installation instructions.
