Rear hub assembly diagnosis expert

[sebpv]

Hi, just disassembled the rear brake and I wanted an opinion on the overall look of my hub assembly. I dont know whats good, normal or bad. So heres a picture:

Sorry I dont think its necessary to show the internals. The bearings beads each rolls freely. Its covered in "clean" uniform black oil. The axle seal is good, intact and soft. There was a thin film of grease/dirt/dust coated on the drum internals. But I dont know how to translate that grease you can see between the axle and the backing plate... Help?

It looks normal.

 

Oil is bad. What I would do is pull the axle shaft, pack it with axle bearing grease, and fit a new seal.

Looks clean and dry, leave alone.

Check for a bad wheel cylinder too...

Just had 2 bolts to remove, so I figured what the hell, just do it. Im not good with words so:

Keep in mind I pressured washed where accessible. Behind the hub I couldnt, hence the gunk u saw...Also by the look of the "clean ring" u can see the axle seal does its intended job. The wheel cylinder is being looked at. It still have the rubber cups and all. But the lower thingy had what looked like "dried coolant" before I washed it.

Yes, you can see how the bearing grease is gone. Good that you caught it in time.

some shmuck...

Yup, she's wet...

[sebpv]

Ok so you say I need a new bearing? Based on the fact that the bearing is covered in oil? So lemme guess: grease normally in the hub compartment and oil beyond the seal?

[ggzilla]

Yes grease normally in the bearing and oil beyond the seal. No one said anything about needing a new bearing.

[sebpv]

Ya sorry. But now I take I need at the very least a new axle seal?

[ggzilla]

Well its not required. Back in the day when I had no money I would pack the bearing every couple months when the leaking oil washed out the grease and started showing. However if you replace the seal it ought a be good for years.

Thanks everyone for your help and quick replies. I LOVE RATSUN.NET!

 

To confirm your sayings I pulled the pass brake assembly.

Yup grease in the hub assembly...

[sebpv]

Now can someone expend on the hammer and piece of wood technique to remove the bearing?

First I straighten the "gear" tooth I guess, but then? I also read something about hammering the front hub counter-clockwise but why and how?

[ggzilla]

Don't remove the bearing. Just pack it with grease. Work it in with your fingers.

 

Btw good use of photos.

[sebpv]

thanks!

[sebpv]

Should I be worried that the outer bearing could be dry as well? Will the grease make it all the way to the front face of the hub? And should i hit the hub assembly with brake cleaner first in order to get as much oil out as possible?

[ggzilla]

You want to grease the bearing, not the hub. Do you have a repair manual?

[sebpv]

Ive got the Haines manual if thats what you mean. To be honest, I didnt think about reading that section
