I have an 03 Rubicon with a 4.5" Rubicon Express lift, and 1" body lift running 315/75 r16s. It has been lifted for 5 years, and I finally have started hearing a noise out of the steering. At first I thought it was my tie rod ends needing grease, but after greasing every possible point of the tie rods the sound persisted. The sound is most prevelant at slow speed, or stop when turning the steering wheel over a quarter turn, not going to try at 50 MPH. The noise seems to be coming from the lower u-joint connecting the steering arm to the steering box, or the steering box. All of the fluids are within tolerance so I am kinda at a loss. I sprayed the u-joint with liquid wrench, (because there was no grease fitting) and the noise was still there. Please help. I have never swapped the steering fluid, but I only have about 65K on the jeep.
