Installing new birfs.....I mangled one axle seal trying to press it into place. I started by hand pressing it in and then mildly tapping in "star pattern" to get it to seat. It didn't go so well. I put another in and although I got it to seal it was a little rough. I can't seem to get a flush start and end up having one side slightly more flush than the other and there begins the trouble.....I have read through a few threads here and elsewhere but not seeing much detail on how best to do this. Any advise is greatly appreciated. Thank you.

See above post. I forgot to tag you so you would see it.
 
^^^^^ 2x (used both options above)

Worked well for this novice.
 
I used the backside of a 1 1/2” socket and an extension, greased the inner axle and the sides of the seal before starting it and took my time tapping it slowly until flush. Then it recessed it further with my brass drift by working my way around the outer edge making sure I was contacting the exterior edge of the seal as I gently tapped.
 
Guys thanks so much!

Pin Head - Thanks and yep did that.

77Mustard40 - Thats exactly what I tried to do and failed...I just didnt have the "touch". Brass drift would have no doubt helped. Harbor freight here I come.....

Biltforme - Thanks and going to buy that offset driver!
 
I've done it without the Wits End tool and I'm never doing that again. It's such a critical seal, often misinstalled, and the Wits End tool makes it goof proof.
Before I tear into my front end this fall I'm buying the Wits End seal installer. Genius, no moving parts, foolproof, etc. Money well spent. (No affiliation with Wits End here, just impressed by the consistent solutions that are well executed.)
 
I think that some seals fail because they get doinked by installing the axle, especially on the long side. Be careful installing the axle.
 
Harbor Freight 50 mm seal and race driver. Perfect for the trunnion race and axle seal. When using it to drive the seal in, the axle housing will "shave off" a hair's width of the diver thereby allowing the driver to recess the seal properly. I've used this 1/2 a dozen times. :cheers:

You'd be money ahead, and better off buying the wittts end piloted seal installer that BILT4ME listed above. The difference between it, and the harbor freight tool, the witts end tool has a piloted tip and shoulder that holds the seal true while being installed. That shoulder also insures that when the seal is finished being installed to it's correct depth in the axles housing, that the seals lip will end up being true, and square to the axles shaft that turns on it.

FIFY.

Sadly, that seal isn’t so easily fixed (It does look proud of the chamfer compared to the bottom where it’s recessed beyond the chamfer).

At least if you catch birf soup, you’ll know what happened :meh:
 
Sure sure pick apart the picture I used but it remains that all 6 axles that I've serviced and twice on my own truck, the seals are properly seated.

Absolutely nothing wrong with the Harbor Freight seal drivers. It should also be mentioned that the kit contains the correct driver for the wheel bearing races.
