Axle drive shaft seal question

Hi - I've read a lot of the previous postings on this topic including Birdman's tutorial, before investigating a passenger (right) side small oil leak of my 1986 328 that I've owned for just over a year. After removing the CV assembly and extracting the 19mm bolt, I attach a picture of the bolt with teflon added by someone who has been here before... Before taking out the bolt which was really tight, I noticed maybe 0.5 mm axial play in the flange, I should have measured it, but didn't. But what worries me more is the other photograph. I thought that I should just be able to take out the washer and remove the flange, then replace the seal, Is what I see normal? Thanks for any advice.

Thanks! In the picture I was being confused by silicon/teflon masquerading as metal near the splines. Cleaned up properly, looks OK now. Yes, I have various sealants and lubricants, I need to review what I have. Well now to pull off the flange, it moves by hand several mm and then hangs up, should I use a puller? I worry a bit that someone else got to this phase and gave up try to get the flange off, hence the teflon.

 

OK! will do. Much appreciated. Somehow, doing surgery on my Ferrari feels a bit different that on my Mustangs for which if you screw up big time parts are available, and affordable!
