FORD 2013 Mustang v.3 - Manual (Page 199)

Replace the rear axle lubricant anytime the rear axle has been
submerged in water. Water may have contaminated the rear axle
lubricant, which is not normally checked or changed unless a leak is
suspected or other axle repair is required.
WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift and
dollies or flatbed equipment. Do not tow with a slingbelt. Ford Motor
Company has not approved a slingbelt towing procedure. If the vehicle is
towed incorrectly, or by any other means, vehicle damage may occur.
Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
If your vehicle is to be towed from the front using wheel lift equipment,
the rear wheels (drive wheels) must be placed on a dolly to prevent
damage to the transmission.
