Ok, i feel like a complete eegit asking this but i am sooo pi**ed of with them now and having fitted a new one yesterday to my driver (so, obv rear drums) do i have to 'press' the oil seal in more than just on its lip becuase when i fitted it, it came off the back and the inner race also came off the back and both are now on the stub rather than within the drum/housing. any help please let me know asap becuase its dry and i wanna go out in it!cheers
