Worn Out Hub?

I had a cyclical noise on my 83 300sd coming from the front drivers side wheel. The brakes looked good, so I have been focusing on the wheel bearings.

On beginning to work on removing the inner race, I noticed that the race could spin free in the hub. It still had to be punched out, but when seated against the hub it was loose enough to rotate.

I cooled the new race in the freezer, and used the old one to pound it in. It went in too easy, just a few taps around. The new one not only rotates but wiggles. It got a little more snug when it warmed up, but it still spins and has some play.

I assume this means the hub has been ground out by the old race, and that I need to get a new/used hub. I figured before I did that, I'd check here to verify that this is abnormal, and that there wasn't some simple fix, that I was ignorant of.

Any Advice?

Abnormal. Some People have even had trouble tapping the Races out of the Hub due to them being tight.

I would say your Hub is now in the junk catagory.

If you have a PNP type yard, pull one off a wreck, I believe the 123 hubs are the same also.

You might luck out and find a set of (126) new Rotors to go along with the Hub. see new one`s every once in a while.

Note: Noticed you have a 83 126, the rotors to 85 would be the same. 86 to 91 they use a larger rotor, so would need to use a 15 inch or larger wheel. the Hubs should be the same.

there were three HP ratings on the OM616...

1) Not much power
2) Even less power
3) Not nearly enough power!! 240D w/auto

Anyone that thinks a 240D is slow drives too fast.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
