EAGLE-EYED RG Colorado owners might notice there’s something a little off with Jamin’s front hubs. In factory configuration the RG Colorado utilises drive-flanges permanently connecting the wheels to the rest of the drivetrain (like most modern 4x4s). It’s a fool-proof solution, but the downside is the CV joints are constantly spinning, as is the diff centre. A free-wheeling hub allows you to physically break that connection when 4x4 isn’t required, resulting in less driveline drag as well as less wear and tear on the CV joints and front diff. After fitting a set of factory Aisin freewheeling-hubs off an older TF Rodeo, Jamin’s seeing fuel figures as low as low as 14L/100km on 35-inch tyres when towing a 1500kg caravan.
