WIP: Replacing heating coil in dryer

I feel like I have a moral responsibility to attempt to repair anything before making it waste. So I'm trying my hand at the dryer. Sadly I didnt' realize that the whole tub joint pops upwards so I detached the tub from the join and then found the join comes off pretty easy anyways.

Anyhow, everything is made of garbage these days:

But I think I can replace that. But while I'm in there: any recommendations on how to lubricate the tub joint? Anything else I should be replacing while I've got it apart? I noticed the tape sealing up the exhauste has disintegrated so I figure I should replace that with a strip of aluminum duct tape.
