I started noticing the clunking around 18000 kms (11000 miles).

8100 miles only can here it in parking lots at low low low speeds!

Had "them" replaced twice in 9800 miles

Alot of different mileages, eh?Guess take to Dealer when clunks and make em replace with new shaft. Lucky I'm Loud and Large, and bought alot of cars off them . Cause the shafts gonna get replaced and let me have a tube of of that majic lube.
