It was a huge bitch to put in my 2 new rear axle seals. I tried for about an hour with a rubber mallot and assorted objects, but it just didn't want to go in straight. I even grinded the little chamfer a little, but it still wouldn't go in. So finally, after I had my new bearings pressed on, I slid the seal over the retaining collar and tapped the axle in partially to get the seal started. This method was pretty easy because the bearing is an easier fit and the collar holds the seal straight. After I got it started I pulled the axle back out and tapped the seal the rest of the way in. Anyone else used this method?

On the upside, my project is starting to pickup the pace. Now I have my SE rear end installed with the PB&J rear end mod, Tokico Blues, RB Springs, new end seals and a new pinion seal, and new bearings, spacers, and retaining collars. Next up is R&R for the SE trans...

 

That's strange. I've never had any trouble just tapping them in.

 

I had problems getting my seals in also. It took a long time, but I tapped them in.

I suspect there that the axle housing has pretty tight tolerances for the seal and bearing, and some of the aftermarket seals (like I used) may not be quite right, causing installation headaches.

Did you use Mazda factory or other seals?

 

They were mazda factory seals, got them from Victoria British.
