In connection with the registration under the Securities Act of 1933, as amended (the "Act"), by Meritor, Inc., an Indiana corporation (the "Company"), of the Company's debt securities (the "Debt Securities"), which may include guarantees of the Debt Securities (the "Guarantees") by direct and indirect subsidiaries of the Company (the "Guarantors"), shares of the Company's Common Stock, par value $1 per share (the "Common Stock"), shares of the Company's Preferred Stock, no par value (the "Preferred Stock"), and the Company's warrants to purchase Debt Securities, Common Stock and Preferred Stock (the "Warrants" and, collectively with the Debt Securities, the Guarantees, the Common Stock and the Preferred Stock, the "Securities"), to be offered and sold by the Company from time to time in accordance with Rule 415 under the Act, we advise as follows:

As counsel for the Company, we are familiar with the Restated Articles of Incorporation and By-Laws of the Company, each as amended to the date hereof, and we have reviewed (i) the Registration Statement on Form S-3 to be filed by the Company under the Act with respect to the Securities (the "Registration Statement"), (ii) (A) the indenture dated as of April 1, 1998, as supplemented by the supplemental indentures dated as of July 7, 2000, June 23, 2006, May 31, 2013 and February 13, 2014, between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor to BNY Midwest Trust Company as successor to The Chase Manhattan Bank), as trustee (the "Trustee"), each to be incorporated by reference as exhibits to the Registration Statement and (B) the form of indenture to be entered into between the Company and the Trustee, included as an exhibit to the Registration Statement and under which the Debt Securities may be issued (collectively, the "Indentures") and (iii) the corporate proceedings taken by the Company in connection with the authorization of the Securities. We have also examined originals, or copies certified or otherwise authenticated to our satisfaction, of such corporate records of the Company and other instruments, certificates of public officials and representatives of the Company, and other documents as we have deemed necessary as a basis for the opinions hereinafter expressed. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. As to questions of fact material to this opinion, we have, when relevant facts were not independently established, relied upon certificates of officers of the Company and appropriate public officials.
