Ladies and Gentlemen:

In connection with the registration under the Securities Act of 1933, as amended (the “Act”), by Meritor, Inc., an Indiana corporation (the “Company”), of an indeterminate amount of the Company's debt securities (the "Debt Securities"), which may include guarantees of the Debt Securities (the “Guarantees”) by 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 pursuant to a registration statement on Form S-3 (the “Registration Statement”) being filed by the Company pursuant to the Act, we advise as follows.

As counsel for the Company, we are familiar with the Company’s Amended and Restated Articles of Incorporation and Amended and Restated By-Laws, each as amended through the date hereof, and in connection with our opinion, we have reviewed (i) 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, February 13, 2014 and June 8, 2020, 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, 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 a 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 Registration Statement, the Indentures and the authorization of the Securities. We have also examined such other documents, corporate records and instruments, and have examined such laws and regulations, as we have deemed necessary for purposes of this opinion. In such examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies and the legal capacity of all natural persons. As to matters of fact material to our opinion in this letter, we have relied upon certificates and statements from officers and other employees of the Company, public officials and other appropriate persons.
