Why do you want to remove it? I had the same problem, alot of twisting pushing and pulling, maybe get creative with a slide hammer. Yes the packing is bunching up.
Why remove it? To get it out.
But seriously, you confirm my suspicion on the packing bunching up. Sucks. I should have wrapped it in tin foil before installation. I thought I was silly to even consider it because the manufacturer certainly knows what they're doing, right? Right?
Don't own a slide hammer. Might be a time to finally buy one. *sigh*
So more lubricant and twisting.
