Has anyone had any experience attempting to lubricate/disassemble a cab top motor? One motor is making a shaking/grinding type noise for a short period when top is going down(doesnt make any noise when raising).

I ordered the 993 manuals (UPON3RACING.COM $288) but they havent arrived yet. Is there anything in the manual on disassembling/lubricating the top motor?

Thanks for any help.
