I am currently trying to put my hub back on but I cant get the knuckle seal to seat on the stub axle. Please help I need my truck tommorrow and its getting too late to beat the hell out of it with a hammer. Any body that has done this please help. I posted this is 911 also but i had to go here too

I wouldn't suggest doing this without a knuckle seal installer. Not only is the seal an extremely tight fit to the shaft, it also must be installed to a specific depth on both the axle shaft and in the knuckle.They damage easily so i wouldn't hit it with a hammer. Maybe someone else has some good ideas?

Well the depth part is easy on the axel shaft I can see exactly where the old one went on to. The i will install the shaft in the knuckle and let the hub seat it to the correct depth. I found a thread with photos on how to do it without the tool but the photos are gone now.

Make your own tool!

Go to the plumbing supply store and pick up (1) ea.

1 1/4 - Floor flange
1 1/4 - 8" nipple
1 1/4 - cap

The flange has to be cut-down on the outside diameter to fit inside the metal lip of the seal (@ 1/8" off). If you have access to a lathe it's a fast cut, otherwise you'll have to mark & grind it.

I had no problem with determining the proper depth as there was a recess cut in the inside of the hub and the seal sat just a bit beyond.

You have to give it a good shot with a deadblow (or big hammer) to get it to move because it won't just "tap" in.

Also you need to clean up the interior of the hub really well and apply a light grease. If you have a cylinder hone you can get it "bright" after you scrape & sand away the crud.

It's really very easy to do, I just did it las month -> Ft Axle U-joints as big a pain to change as they look?
