This is always good to read

"Dana and certain of our U.S. subsidiaries are operating under Chapter 11 of the U.S. Bankruptcy Code as debtors-in-possession. Information about the bankruptcy proceedings can be found at: http://www.dana.com/reorganization.

WARNING: While we continue our reorganization under Chapter 11, investments in our securities will be highly speculative. Although shares of our common stock continue to trade on the Over the Counter Bulletin Board (OTCBB) under the symbol "DCNAQ," the trading prices of the shares may have little or no relationship to the actual recovery, if any, by the holders under any eventual court-approved reorganization plan. The opportunity for any recovery by holders of our common stock under such reorganization plan is uncertain and shares of our common stock may be cancelled without any compensation pursuant to such plan. "

I would do further research to see if Dana skipped on proper heat treating or proper preload on the carrier or gears.
