Clean Wheel Knuckle?
After scrubbing with 3M pad!
Hey guys,
I am replacing my 2003 7.3's front wheel hubs and brakes. When I removed the old hub, I realized how filthy the mating surface to the knuckle was totally crapped up. I didn't want to wire wheel the surface for fear of scratching the hell out of it. Any suggestions on how to clean it off, or is it good enough to grease up the inside and just install the new hub? Also, the spacer that is inside the knuckle goes with the groves facing inward, correct?

Update - I just put the new one on, after greasing the inside etc. I found a video and it looks like the spacer has the 4 groves facing inward from this video:
. If anyone can confirm I did it correctly I would appreciate it 
. I'll see from the other side which way that spacer faces too....

I use a wire wheel to clean the knuckle surface with no worries.
The fiber thrust washer should be installed with the grooves facing inboard.
As bad as that bearing was, I'd carefully inspect the stub shaft for wear at the bearing surface.
Good work!

Ok, I have an extra o ring, so I’ll pull the hub back off and drill wire wheel it to clean it up. The inside surfaces actually look ok, it’s just the outside area due to rust that looks horrible.

Canyon, I also applied a thin layer of timken bearing grease to the fiber thrust washer and the inner metal seal it sits on, is this correct or should I brake clean off those areas.?
