I am going to tackle the clutch replacement on my 2015 F30 N55 as a DIY project. Now that I am working from home, I'm not worried about having the car up on stands for a week if it takes longer than expected.

I am FBO with 80,000 miles and plan to install a new dual mass flywheel and upgraded 335is/550 clutch. I just ordered the parts but I'm wondering if there is anything else I should replace in the transmission or drive shaft. Should I replace the Guibo while I have everything taken apart? Any other seals, bushings, gaskets or supports I should replace that usually fail by 100,000 miles. I've attached diagrams of the transmission and drive shaft to make it easy to call out specific numbers of any parts that you think should be replaced as preventative maintenance.

Thanks!

Off the top of my head, i imagine it would be smart to at least inspect the rear main seal while you are in there. Not sure if it warrants replacing without any issues. And change fluid in the trans and diff.

None of the components are maintenance items. Just replace them if they are worn. It wouldn't hurt to get under the car, remove the trim panels, and do a quick inspections for cracks and leaks. Otherwise, just replace the clutch.

I made a DIY if you haven't seen it already. Hope it helps.

What Kern417 said. He's got a great and thorough clutch replacement video on his youtube which helped guide the video I made on the topic w/ my mechanic
