Left front differential seal and bearing replacement
 

Hi all,

Well, I've determined that at least I will need to replace the seal/cover plate on the left side of my front differential on my 1999 Blazer LT. I've even found the part number (12471587). https://www.tascaparts.com/oem-parts...Y2LWdhcw%3D%3D

What I would like to know is since I'll have the whole left front suspension apart to replace the seal, should I also replace the bearing? I found a video (link below) that made me think it is worth doing. Also is that I have a leak at the seal evidence enough that the bearing should be replaced too? I did feel a little bit of wiggle, hardly any at all, but there was more than on the other side.

Finally, if I should replace the bearing, any advice on the procedure and does anyone know the part number? I've been having a very hard time finding what that part number would be.

Not to change the subject but I checked out the website link you posted and it's pretty good. I found things I couldn't find elsewhere. Thanks!

If it's a cheap repair, I would do it all at once. Save having to tear apart twice, just in case.

Yeah, that is my logic. However, I don't want to mess with anything that I could mess up and which to fix would be more of a hassle! :)

Quick update:

I called the local Chevy dealer and here is (what should be) the part number for the left output bearing: 26053326
