Put the Renegade Trailhawk on the lift today. Checked out some of the fasteners, lots and lots of E-Torx, fair amount of regular Torx, quite a few six-point. One captive-nut on the rear-end that I expect will be a headache for people servicing dirty vehicles. E18, E16, E14, all very common on suspension/brakes. T50 and below pretty common. Bigger than E18 present for suspension-to-body fasteners, I tested one of those 12-spline jobs and the 16mm version fits, would probably want to use E-Torx if actually spinning them. The skidplates are 10mm and 13mm six-point. I found 10mm and 12mm-18mm, nothing that I touched was 11. Rear differential uses Allen, didn't check the size. Both fill and drain appear to be the same.
