[QUOTE="Drew Lonker, post: 1018118, member: 70642"] I have an 01 4x4 Sport trac with 110,000 miles on it and have recently noticed a clunking noise coming from the rear differential area (limited slip diff fyi). I decided to change the differential fluid to see if that would help and noticed my spider gears were all chew up. I replaced them and put in new fluid (75w-140 synthetic) and friction modifier and still get the clunk. It only happens if I weave from side to side or go over some uneven road like train tracks. It sounds like some medal is moving from side to side and hitting something. Could it be u joints? Any ideas would be great! Thanks [/QUOTE]
