GHW9300PW - Whirlpool duet washer - Front tub seal, bellow replacement

I am new to this forum. Please help me.

My 2.5 year old Whirl Pool duets Front tub seal, bellow is ripped 50%. And water is leaking from this.

I need to replace it [Front tub seal, bellow] …

Does anyone has any instructions how to do it yourself? is this relatively easy to do?
Do I need any other [SIZE=2]accessories?
[/SIZE]?

Thanks,
Jingi
