Installation of a bike rack on the Jeep mainly depends on your chosen frame. In the case of a hitch rack, assemble the hitch, then attach the rack's pole to the open space of the hitch. After that, turn the knob clockwise to secure it. For a spare tire-mounted rack, start by detaching the spare tire from the bike rack and adjusting the mounting plate of the tire holders. It is common for the stand to include a plate to hold it in place and various tongue choices with varying lengths.
