I put a new driveshaft support bearing on my 88 240 and in the process of removing the old one, I broke off a small dics that was welded inside the shaft. I was using it to push off on when I pulled the old bearing off hte shaft.

Now it is tickling around inside the shaft and I can not get at it with anything to cut it or remove it.

All I want to do is keep it quiet and stop it from making noise everythime I drive the car. I thought about some spray foam to hold it still. Before that, I would locate the disc at the far end laying flat.

Any other suggestions?

Somewhat glad to hear I'm not the only one to do this! Sorry it happened to you.

My guess is the plug is there to prevent grease from the splines migrating forward and possibly unbalancing the drive shaft. Your suggested repair most likely would be okay and work just fine. Certainly a lot less work than what I did. I CAN get carried away at times.

I drilled a 1/2" hole in the center of the u-joint saddle at the opposite end of the shaft. I then took a 7/16" steel rod and drilled a centered hole at one end and pressed in a small pin (approximately 1/8" diameter). The pin is to allow the rod to center on the plug which has a small hole in the center.


Using the rod as a driver, I got the plug back where it should be and tapped it into place. I took this approach as I believe the plug is pressed, not welded in place.

To finish up, I sealed the hole in the saddle by pressing in an aluminum plug.

No problems since the repair was done in 2009. I took photos, but can't find them.
