I need to change my front left needle bearing (wheel bearing) on my 2002 f250 4x4 7.3L.
You're asking about two different bearings:
There is a
wheel bearing .... not replaceable/repackable
There is also a
needle bearing in the hub (that the axle end rides in) ... that is both replaceable and repackable, and is part of preventive maintenace.
Here is the needle bearing .....
Hope this helps.
