My extended warranty doesn't cover the removal and replacement of the aforementioned gaskets/seals and I was wondering if anyone here has done them before and had any tips for me ? Depending on the level of complexity I'd like to try to do them on my own but it looks as if there's quite a bit of work involved in doing so and I have no idea where to start here.

If there's anyone here that could shed some insight I'd be forever in your debt
