2000 323ci 40k miles when subframe started to crack. Fixed by BMW.

So can someone post more definitive ways on how one can tell if their subframe is damaged?

I heard from someone that you could reinforce the subframe from up top. Can anyone confirm this is possible?

For those who had their subframe crack/ripped out, list all the symptoms/signs you had that something was wrong so other fanatics could keep a look out for it.

I dont' think there's anyway you could reinforce it from the top. From the top... it's just the inside of your trunk. You'd have to cut through your trunk to see where the subframe connects with the frame.

Some dude said thats how they reinforced it in his car. Easier that way compared to removing everything from the bottom.

The guys who've had this happen to them. Please list your symptoms. Is the crack visable from inside the trunk near the spare tire area?

I wonder whats the ratio of the E36 guys having this failure compared to the E46.

clunking noise coming from the rear of the car while driving, you can also feel some vibration while the car is moving at certain speeds. The crack is visable if you look underneath your car, you can see the rear diff mounts ripping from the subframe/undercarriage, or any other cracking around that area.
