Just picked up a 2nd XJ today, a 93 Country with AW4 and the 242 Selec Trac T/C. The 4wd works fine but in 4lo and 4hi it has a slight grinding/dragging type noise when you decelerate. In 2wd and 4wd full time it sounds completely normal but this noise in part time is kinda concerning. My other XJ has a 231 w/ 5speed and does not do it, but not really an apples to apples comparison. To elaborate on the noise, sounds like brakes when something drags on the rotor. Thoughts?
