Drivers side inner axle seal is leaking on my 99 Cherokee.........I went to the local NAPA and bought a set, they looked like these:

but were $19. each so they had to be made different.

When I pulled the old ones out they looked like these:

but do not have the flare, as the one in the right side illustration.

I also found these which look the same:

Which style is the right one for the Cherokee?

 

The second set is for disco axles that's why there are two different types shown. Either of the other tow will work.

 

I don't have the disco axles......but the second ones are the right size.......the first set had too small of a diameter hole in them.

 

They should fit tight but with the second set you'd need to buy 2 sets so you'd have 2 for the ones inside the diff. Best to change both even if only one is leaking since they are the same age it's only a matter of time.

 

The ones inside the diff. are the only seals on the axles.

 

The second set you listed has one in the diff on the driver side and one in the middle of the passenger side tube. That's why they look different.
