A problem I just came across:
1)Clicking at low speeds, vibration between 40-60 MPH on my LR2 2010 HSE 4X4.
2)Raised the rear wheels, chocked the front wheels
3)Checked for center bearing wear (2 center bearings) . NO WEAR
In order to check center bearing rubber, had to remove cross-members and exhaust hanger.
4)Checked for end play of driveshafts at both transmission end and rear axle end none.
5)When spinning rear tires, noticed the clicking occurring on sudden stops and starts even with wheels raised.
6) No wheel bearing issues, wheels rolled without getting stuck or noise.
7)Checked the six male torx screws going into the differential input and all 6 screws were relatively loose causing rotational play.
8)Re-tightened the 6 torx screws as tight as possible. This is difficult since there is not much room between side of driveline flange and bolts .
9)Assembled center bearings and exhaust hanger, drove car for 5 miles. No clicking or vibration.
