Just picked up an 05 KJ Renegade for our niece and wanted to make it more reliable. I’ve learned a bunch from this forum already, so the fixes and mods I’m doing all have a tight budget in mind. After inspecting everything, we made a list of what we wanted to replace. Some of the items include: headlights, front blinkers, shocks, springs, brakes, tires, hood & back glass struts, wipers...... There is a lot more, but I’m at a loss right now. I wasn’t going to spend extra on the suspension, even though I’ve read about the better spring options. I went with AC Delco rear springs as they had a progressive rate vs the constant on the Moogs. I was SHOCKED at the difference in diameter of the OEM springs vs the Delco’s. The top 2 coils of the OEM springs are narrow in diameter, which threw me off. This is likely part of the reason for the sagging over time. I’d never seen that. The Delco’s were the same, thick, diameter from top to bottom. I meant to get pics of the 2 side by side, but forgot. I also changed the rear rotors and pads. Pic of the completed install: Pretty easy job overall. The first side (passenger) took me a while as I got familiar with everything, but the driver’s side took me less than an hour from wheel off to wheel on. I dropped the shocks first, which gave me enough room to swap out the springs without much effort. The shocks are held in by 15mm bolts, but the bottom bolt also has an 18mm nut holding it on. I then bolted the new shock in and removed the caliper and rotor. The rear calipers have 13mm bolts holding them.
