I'm currently in the proccess of replacing my friends front upper and lower ball joints on an 89 *-15 Extended 4X4. Naturally i had to take off the entire hub assembly. The inner wheel bearing seal (rubber) has come loose from its seating position, or is this how it is supposed to be?

Also is it okay to reuse this as long as it is placed in a way that when the hub nut is tightened, it is seated so that it is compressed and is sealed against the CV assembly? He doesn't go through water or mud up to the rim so i figured it would be okay to reuse this.

This truck is his daily driver and he needs it to travel to and from work.
