Can someone help me with the make and part number for axle seals for the above. I drove the seals in to the race and the round spring tensioner that provides tension to the seal fell out on both seals. I put them back in however it doesnt seem to seal tight to the axle so Im thinking I need to remove seals and replace with new ones. I used info in this post to locate seals. http://www.camaros.net/forums/showthread.php?t=154773&highlight=moser+12+bolt+seal Thanks

Sorry can't help with part# :( but when it comes to hitting these seals with tensioners in, fill the seal with Vasoline. It will hold the spring in place :thumbsup:

Thanks for the tip. I can put the tensioners back in however it seems loose around the axles.

It's a 9 inch Ford truck seal from the late '70s.

Thanks, so any seal from that era of Ford trucks will work? The local parts store cant find anything without specific info unfortunately :-)

Yea, it's too bad that we have lost the parts man who actually knows what he is doing and now all we have is kids who can't find anything unless it's on the computer in front of them. I'm blessed with an old parts store with guys who still know how to find a part without a computer. Most of the time they don't even look it up, they just go to the shelf and get it.

I believe you want National 473228 or CR 15142.

1.500" x 2.502" x 0.312"

Those are correct for me for a Chevy 12 bolt with Ford ends and 33 spline Moser axles.

Thanks!

A National# 51098 is the seal I use for those. It's a better seal than the 473228,and the 51098 is a little more common in the parts stores.

I know that a phone call to Moser is tough and all, but....

Here's what I found to drive them in with. Measure the diameter of the housing. Go to the pipe section of an Ace or other hardware store. Get a steel pipe nipple six inches long or so and also a cap and coupler that will fit just inside the bearing housing (the coupler will be a larger outside diameter than the nipple when installed). The coupler should be smooth on the edge. Screw the cap on one side of the nipple and the coupler on the other. Wah-lah, you now have a seal driver.

I lightly smeared a bit of RTV in the housing end when I installed mine. When wet, it is slippery so it helps the seal slide and will help seal the seal....at least I've been told.

Go by a seal driver kit at harbor china. They are a biatch to put in and not compromise the seal. I have your exact setup and had the RR leak. Whoever installed the seals originally pushed in the center as you can see in the photo.
