W201 Wheel Bearing Issue

[maranelloboy05]

Struggling a bit with replacing a front wheel bearing on my 2.6. Unfortunately I didn't save the original oil seal but I've now gone through two replacements with neither rear oil seal sitting flush or within the hub, it protrudes about 1mm. I followed the DIY and someone else asked the same question and only got the answer of ensuring it bottoms out, I'm not confident that is correct as even the DIY shows the seal sitting with the hub.

My only thinking is maybe someone in the past replaced the hub from another Benz that looks identical but isnt quite? Has anyone run into this?
