Diagnosis on Pinion Bearing

Ok so i replaced my rear pinion seal to stop a diff leak right there. The leak didnt stop. I got scared and thought it might be the pinion bearing that was causing the leak. I checked my driveshaft and it has no play horizontally or vertically when pushing and pulling on it. Also there is no "whine" noise in my jeep when accelerating or decelerating. Does this 100% mean that the pinion bearing is still good? Is it a good chance i just didnt get the seal in without damaging it slightly? Thanks a lot!

Did you look at the yoke to see if the old seal wore a groove in it? If it did you might have to look at a different brand seal or maybe a speedy sleeve to repair the groove. Just a thought.

What Goobs said. A grooved yoke can cause even a new seal to leak. In my experiences, pinion bearings will often make a hissing noise as they are beginning to fail, then slowly develop into a roar.

I think my yoke did have a groove in it. Tried to fix it with rtv but i guess it didnt work. Whats a speedy sleeve and how do you use it?

I used to sell auto parts back in the day. It used to be a Chicago rawhide part. I think its skf now. it's a thin piece of I think stainless steel that you would put on the yoke where the seal rides. I'm not sure if you would have any luck at auto zone or oreillys cuz if it ain't in the computer they ain't got it.

Ha I just went on Rockauto.com and looked up one for my jeep and they call it a differential pinion repair sleeve. So you should have pretty good luck finding one.

Hope that works. So as long as my drive shaft doesnt move side to side when i push/pull on it that means the bearings are good?
