One of my favorite upgrades to my XJ has been the LED lights. They really light up road signs and anything reflective like stripes on the road or center reflectors. They also work great in the fog and rain.
Correcting the steering on my Renix era Jeep Cherokee with a new drag link tie rod.
After replacing my track bar, I still had play in the steering. The next worst spot was the drag link. I noticed this was loose when I was trying to center the steering wheel after changing the track bar.
While driving in traffic, I heard my electric fan kick on. This is unusual for my Jeep even in traffic. I looked at the gauges and saw the temperature was running much warmer than usual.
I switched on the heater and rolled down the windows. The temperature started to drop slowly. As soon as I started moving again, the temperature dropped back to normal. But each time I stopped, The temperature would rise quickly.
