Replaced axle seal...still leaking

Hi.

I have recently replaced the nearside rear bearing and oil seal (due to oil leaking into inside of handbrake mechanism and disc).

I bought the 3 piece kit from a reputible Jeep parts dealer (not genuine) and fitted to my 2004 Grand Cherokee, which I believe is a dana 44.

I did not replace the cup (with 4 studs), that mates with the oil seal.

It wasn't long before the axle started leaking again.



Any thoughts, tips or ideas?



Thanks, Chris
