pinion seal or rear diff leaking

pinion seal or rear diff leaking?? help

How do I tell which it is. I just noticed the leak yesterday and was hoping to do something about it this weekend but I don't want to do the wrong one. Also if I do one is it easier to just do the other while I am at it.

Please help, I just started working on my truck and am enjoying doing it myself but I am not sure what I can handle and what I need to take to the shop. Thanks

Where on the differential is it leaking? The pinion seal is located on the front of the diff where the driveline connects to the differential. If it's leaking from there, then you likely need to do the pinion seal.

thanks, thats what I needed to know, I am going to check it tonight and hopefully its not the pinion seal, I think I can drain and refill the diff but I don't know if I can do the pinion seal.
