Guys I haven't seen a post on this task before and I have to remove the front axles once again to have a look at my front diff adjustment. As it's a pretty filthy job, I'd really not do it again (after this) ever really! It will be interesting to see how it all looks inside there after I serviced both sides recently. Just nice to see that it all looks like it should. But as I say, not seen a wiper seal replacement thread before. Are they replaced from the outside or are they split somehow to go over the axle? Do you have to remove all of the swivel hub too - ie top and bottom pins and all? I have a feeling that the answer coming back is going to be - yes. All the gubbins has to come off. I don't think I have a problem with them at the moment, but if it's easy enough I may as well get it done.
