About 60% of the trailer load should be in the front half of the trailer and the remaining 40% in the rear. HITCHES D Use only weight carrying hitch hardware designed for the total trailer weight with the factory installed hitch. D If you wish to install an aftermarket hitch, the hitch must be bolted securely to the vehicle frame and installed according to the hitch manufactures' instructions. D The hitch ball and king pin should have a light coat of grease. D Toyota recommends the ball mount assembly be removed when not towing to prevent injury and to prevent damage in the event of a rear end collision. After removing the ball mount assembly, install the grommet to the hitch to prevent entry of dirt and mud. D The trailer cargo load should be distributed so that the tongue load is 9 to 11% of the total trailer weight, not exceeding the maximum load of the following. NOTICE Do not use axle-mounted hitches as they can cause damage to the axle housing, wheel bearings, wheels or tires. Also, never install a hitch which may interfere with the normal function of an Energy Absorbing Bumper, if so equipped. 264 2003 4RUNNER from Oct. '02 Prod. (OM35804U)
