You will also need to buy a few expanding rivets, since it's likely you'll mutilate the old ones getting them out.

I replaced a similar part for the rear wheels in my X3 when they simply became torn/ragged/hanging on by a thread after years of use. Expect them to cost around $10-14 each.

Also part # 51 75 7 188 839 (for L side) in the BMW US Parts software at your local BMW dealer. It is officially called a Pressure Lip Seal. This is for a 2011 X5 5.0i, I would imagine it would be the same part # for other models of that year.
