D30 pinion, does this sound right?

This is my Dana 30, I just replaced the pinion seal, and I have the carrier out in order to do the inner seals. When I did the pinion seal I marked everything so it went right back to the same position.

Never Had any issues with it when it was on the jeep, hence why i am only doing the seals.

However, when I spun the shaft it just seemed to sound different then I would imagine.

Does it just sound this way because of no carrier, or should I look into taking it apart again and replacing bearings?

thanks

Almost sounds like the slinger is dragging on the housing.

Did you wash the bearings out with solvent? Did you try oiling the bearings with gear lube?

Some brake clean may Have found its way in there. I filled it with gear lube and the sound was exactly the same.

Something is dragging or rubbing. That's not a lubrication issue noise.

Must be the outer oil slanger! Come to think of it, when I was pulling the seal my screwdriver slipped and bent it a little, I took it out and flattened it all out again, but maybe that was not enough.

It didnt rub when I put it back, but tightening it down may have changed that, I will pull it back out, will only cost me a new seal. And cleaning some Rtv

Alright, so I took the yoke off, and my seal and pulled the slinger, Where it rides in the housing there was a little gash and bulge, i must have did that when removing the old seal. ground it smooth, and cleaned it all out.

I removed the pinion, looked over things, and re greased all the bearings and components, put it back to together, without seal, first without the slinger, and it sounded bout the same, and then with the slinger, which is the video.

I guess it may just be how it sounds? Bearings looked great, nothing else dragging. I will be ordering a new seal, and reinstalling.

Also, The Dana 30 must not have a crush sleeve? Didnt see it.

I also saw that the inner race, the little tin baffle that is there was a little bent on one edge, I thought that might be it, but i flattened it out, and it didnt change.

I also tested it by holding the pinion inner bearing just against the edge of the housing and turned it, and it made the same noise, so I think its just how it sounds in an empty housing....

Ruined a seal for nothin!

If nothing is rubbing, then your bearings are worn, a new quality bearing is as smooth as glass. The empty housing is acting like an amplifier. Shouldn't be a problem for you unless you are in 4 wheel drive a lot. Just my 2 cents worth.

Its not as easy as just buying new bearings is it? I would need to get new races too?

If the bearings,races and pinion area is WET with gear oil, all you hear is the echo.
No CS on the D/30
When I do R&P work I keep an oil can filled with gear oil to soak everydangthing as I assemble.
Don't forget to check the backlash and confirm the pattern in at least 2 places.
Hope you used a couple drops of red locktite on the p'nut and paint marked the nut to the pinion.

Have'n you along, is like loose'n 2 good men

Yea I have some grease I put on everything, Good Call on the red loctite, I will pick that up, And yes, I did mark everything this time!

Ill have to do some reading to understand backlash and pattern checking, I was just going to put everything in the exact same way it came out and hope for the best!

Thanks lump
