I don't drive my 31 Tudor very often, just in Parades mostly. The rest of the time it's in storage up on blocks. When I was taking it out of storage yesterday to get her ready for the 4th of July Parade, I noticed a lot of play in the passengers side rear wheel. It's like when a wheel bearing goes bad on a front hub, I took the brake hub off and there looks like a bearing there that has gone bad. Do I have to take the axle out to replace this bearing?
 
I would start with pulling the rear drum. That should tell you if the wheel bearing is bad, or if it is a keyway for the tapered axle. Sometimes the axle nuts are not tight enough. I think 100 foot lbs. is the number. If you have any play in the nut that stresses the axle keyway. The axle key also can shear. Bob

No, if you took the hub and drum off, the bearing is in the hub. Note, when the hub and drum are off, the axel is not supported, and lateral motion is normal.
 
Thanks. I had hoped I could replace it rather quickly because of the parade. I didn't want to have to take the rear end all apart. I get most of my parts from Snyders. Exactly which bearing am I looking for?
 
The bearing is held in place inside the hub by a retainer snap ring and grease seal which have to be removed to remove the bearing. The seal can be stubborn but can be tapped out (after you remove the snap ring) with a long screwdriver and should be replaced for re-assembly Inspect the inner surface of the hub for wear or scoring and also check the bearing race which is the large diameter surface on the end of thr axle housing for any damage. If worn or scored the housing has to be removed and a sleeve can be installed by machining the race and press fitting the sleeve over the old race surface. The original hub inner diameter is 3.188 to 3.190 Check any Model A supply catalog for all the replacement parts mentioned above. Don't forget to hand pack the bearing with grease on re-assembly. I prefer to hand pack the grease rather than use the grease fitting as you can see how much grease is going into the bearing area and avoid blowing out or by-passing the axle seal. http://www.brattons.com/prodtype.as...geHistory=cat&strKeywords=&strSearchCriteria=

do you have any source for someone that can machine the axle bearing surface so as to accept the sleeve?
 
Say MikeInNJ, when installing new grease retainers in the rear drums which way does the open part of the rubber face? The open side of the rubber where you can see the spring down in the groove. Is the open side toward or away from the bearings? Thanks.
 
The way you are describing the "rocking" perhaps a look at the possibility that it isn't the wheel bearing ---and consider the possibility that the hub could be loose on the axle ---if you take the nut off and can pull off the hub/drum assy without using a puller--it's been loose too long

There is a spec that I found in a 39-40 repairmanual for axle housing bearing surface wear---if scored,pitted or worn in excess of .010 for more than 1/2 the width of the bearing surface replace the housing
