W123 Rear Wheel Bearings
 

I am currently replacing the final drive shafts in my 300D. There is nothing about repacking the rear wheel bearings. I figured since I have the axels out, now would be a good time to do the job also. But I also heard that you dont fool with them until they go out. So if thats the case, can you easily access the bearings with the axels in there or will they have to pull the axels anyhow and double the work?

The left side is making a bit of noise when I rotate the hub. The right side is dead quiet.

I know I need the special tool(socket) to dissassemble the wheel bearing assembly. I am wondering if I can take it apart, repack the bearings and replace the seals. I am wondering if all the talk of replacing the bearings and the races are what the big difficulties are or can a person just repack the existing bearings and replace the inner and outer seals without worrying about all the preload stuff and crush seals?

I have done 3 of them and if you have the socket for the nut and a loooong bar to tighten it with(there is a crush ring for the preload) its not a bad job. I have also done two of the on a 124 and they suck, tourch required.

If you have to buy the tool to take them apart why not just change them and be done with it. I cant believe i said that because i am not one to spend money if i can find a way around it.

Your right
 

At this point I have decided to wait until the bearings go. Then I will replace them.

I did replace the axels though. Not a tough job if the guy who sends you the parts sends the correct differential seals as well.

I had to wait until mon to get the seals locally. got lucky on that.

thanks for your reply
