HO72 Wheel Bearing Help
Hello,
I apologize if this is in the wrong section, I was torn between posting this here or in the 67-72 section. Anyways, I have a 1970 C30 with the HO72 rear end. Over the past weekend I was looking at the brakes and found that the passenger side brake's shoes and inner drum were coated with gear oil. I would assume that a bad wheel seal would be to blame for this. But, here is where I'm not too sure: The inner wheel bearing has a LOT of play (back and forth) between the wheel seal and the "cup" that it sits in. Is there a washer or something that goes between the bearing and the seal to help hold everything place? Also, I do not believe the bearing is original as it is a product of Japan, part number 4T-388A. Do you guys think this is just the wrong bearing or am I possibly missing something? I would check the other side but I'm worried about having both rear wheels off the ground and the truck rolling. So, any ideas? Thanks, Brad |

Parts for the eaton differentials are all but impossible to get anymore. Someone more familiar with the eaton rear may be able to help but I know for sure you are going to have a hell of a time finding anything for that differential including wheel bearings.
As a side note this section is exactly where that question belongs.

That is normal. The brg. goes up against the ledge on the spindle The seal rides on the raised portion. The brgs. & seals are readily available. The original brgs are a conical style. The replacement is straight roller brgs. If you replace the inner or outer you are supposed to replace the other one also.
