TR2/3/3A Replacing Lockheed Axle Seals 56 TR3

Share this page

I don't think so...The brake back plate also serves as the bearing retainer, if I remember right. I guess it may be possible to leave the brake shoes assembled on the plate as you remove it, but I think it would be more trouble than just removing the brake shoes to gain access to the backplate bolts. Now, once the backplate is removed, you can pull the hub, axle, and bearing out together.
 
Thank you John, I ll remove it! but the axle shaft will go out when I ll remove the brake back plate?so easy?or need to open the differential?
 
If you look at the breakdown illustration above, you can see that the bearing slides onto the axle, followed by the hub. Once installed, the hub locks the bearing onto the axle. Then, not shown, is that the brake backplate retains the bearing outer race, and holds the seal that rides on the lip of the hub. So, once the brake backplate is removed, the bearing is free to slide out. On Steve's differential it was stuck from years of gummy build-up, but there is nothing solid holding it in. There is no axle lock in the center pumpkin on the Lockheed...it simply slides into the splines. The ball bearing (not a tapered bearing) does all the work of holding the axle in place.

The Lockheed axle was weaker than the later Girling and it leaked, but it was much easier to service than the Girling. You could easily carry a spare axle and a handful of tools, and change the axle in less than an hour on a clean differential.
 
Actually you was right, I am in front of bearing quite easily but, now I am not sure the problem is the bearing , can be is the hub my problem?I mean, hub is not very thigh to the shaft axle and I find few metal dust…
 
If I only could post a smal video I could show hub move on shaft axle

If you look closely inside the hub, you will see a split about an inch inside the splines. That is where the locking collar is still in the hub. You should be able to catch it from the back side with a punch ( or gently on the outside) and tap it out.

The locking collar is tapered on the outside, to center the hub. As you tighten the hub nut the collar centers the hub, and as you continue to tighten the nut, the collar compresses onto the axle splines, locking the hub to the axle. It is possible the nut was not tightened properly.
