Was wondering the correct diameter of the rear hubs on 48 passenger vehicle,(want to check for wear) and since the old fiber grease is no longer available, what is the best. Grease today to use on the bearings. Thanks. Happy Holidays. Rick

Rick- The standard size is 12.00". The maximum safe size is 12.060" (some state laws demand this). However, there are some new drums that are being produce that are thicker and have a maximum 12.090" cast on the drum. As for grease I use Sta-Lube drum brake grease. Hope this helps. Tom

It isn't clear if you mean hubs or brake drums. Most of the wear occurs to the axle housing surface. Examine the underside of the housing for that. Axle housings can be sleeved if the wear is severe. We also use Sta-Lube heavy duty drum brake grease. It has the necessary fibers to protect the bearings. The drums usually wear faster than the hubs if the bearings are kept packed.

I don't know the measurement of the axle housing diameter, but when the axle housings start to wear, you can see the wear pattern on the bottom of the housing. The grease will also have a gray color to it. The best grease for the bearings is StaLube sl3131, It is available at NAPA. Tom
