Changing out hubs on 1988 25' Excella

I have a set of fairly new complete hubs I removed from my other Airstream when I put on disc hyd. brakes. I am refurbishing my 25' 1988 excella and plan to put the better hubs on it. Is there any thing I should know outside of remove and replace in the same order? The ones I plan to install are about 2 yrs. old and are like new.

Hey John. Will you be replacing the bearings at the same time ( recommended ). If so you must also remove and install new bearing races in the new hubs. If you go this route I would advise getting a good set of Timken ( or other American made ) bearings and matched races and, of course, new seals while you're at it. A little extra work but since you're going to go this far you won't be sorry. Go for it.

If the bearings are like new and show no wear they can be reused. I would replace the grease seal as a matter of course, whenever repacking the bearings.

After cleaning the bearings in solvent, visually inspect the outer races and bearing assemblies' surfaces under a good light for scoring/roughness, cracks, and discoloration. Discoloration indicates high heat, and weakened parts. Look for a color range from straw to blue.
With new bearings, I also prefer premium brands, which are packaged against dust--unlike those in open, bulk bins at RV stores.
I get dealer prices on bearings by asking the parts clerk to write it up for Dean's Garage, and telling him or her that I will pay the state sales tax.

Welcome to Airforums.

I would really like to hear some details about your disc brake install. Are you glad that you did it? What components did you use and what was your source?

Thanks in advance, Dan
