DO NOT FILE!!!

Try turning the hub/axle and finding a point where they are happy.

Make sure the hub splines are clean. Small wire brush helps here.

Only touch up any burrs with a file. Do NOT file the splines!

Try putting the axles in the freezer.

As a general rule, if something doesnt go in easy then you are doing something wrong. Stop, slow down and think about what you are doing. Once you start forcing anything the risk of doing great damage increases and it hits your pockets hard especially with mercedes. You shouldnt have to hammer those axles in...

I just did them on a buddy's 300D and it was easy job.

A note for installing the axles back into the hubs. I could not get the axles to go all the way back into the hub. Tried pounding the axle from behind ( on the metal can). No luck. Bought an all thread rod (M8 1.25 X 3ft ) at the local bolt supplier with 2 nuts and a large washer, $5.75. Tried creating a slide hammer to get it to install, still would not go all the way in.
I finally inserted the all thread into the axle. Slid a plate over the rod and installed a washer and nut. Turned the nut with a box wrench and the axle slowly slid into position. Replaced the axle bolt, sleeve and a new washer and torqued to 30Nm as per the manual.

Thanks for the thread DMorrison. I looked all over the search functiona dn I could not find anything that detailed. I truly hope I do not have to go that deep into the hub but I just might.

I filed on the hub this morning after cleaning it very good with brake cleaner.

Do you all think there is a possibility that the axle from the Advanced Auto is machined incorrectly. I think the previous one I had was out of the same lot as the one I have now.

It is possible the axle is not correct. Measure the diameter of the axle spline area to make sure it is the same. Also measure the spline size and gap as well as the total length of the axle part that goes into the wheel hub. If they are the same then by some alltread and install it the way I described above.
the post I linked you to is for replacing the bearings. Not the axle.
Her is the axle post.

The one thing I know for sure is that the splines in the hubs are not faulty.
I think filing either is a bad idea, but if I was going to choose I'd go for the axle.
Personally, I'd look for an axle that fits. They're out there. I know because I did the job.

I borrowed 2 axles that came off of an 83 240D and tried to put them in. Neither one of them worked.
They are going in about a 1/4 of the way and stopping, all 3.

What is going on here.

Have you tried to put the old one back in? Just to see if it will fit.

are these Homokenetic or Annular axles? Annular are the two piece and
maybe separate the two sections and see if it will fit into the hub. If it
will, then stuff it in and attach the other end in the Differential and then
bolt the two halves together.

hard to believe three of them won`t fit.
