Hello everyone! My first post here on Car Talk! Long time listener and am glad to be here on the forum.
I have a 1994 BMW 325 convertible that I recently purchased. I had a mechanic look at it when doing some other work (this is a new mechanic to me, just moved recently) and when he did that he showed me that the drive shaft bearing/support was put on backwards so that the bolts where it is supposed to be bolted to the undercarriage dont match up and it is welded to the undercarriage. The welds look good and dont appear to be cracking or anything but the mechanic said that it isnt safe and the complete drive shaft needs to be replaced.
This seems extreme to me and I’m not sure if I should do it. As i understand welds can be stronger than bolts. If i do replace it can I just have that bearing/support replaced or do I really need a whole new drive shaft? Any help will be appreciated!
