Recently bought an 00 GT with 77K. A random problem comes up when starting out in 1st gear. Sounds/feels like clutch chatter, right front thumps real bad when easing off the clutch. Sometmes when cold, sometimes hot, very pronounced in 1st, limited in reverse. Had it in the shop, went through it all and said CV's look fine, tie rods fine, motor mounts and struts fine etc. Any ideas, perhaps clutch or flywheel is glazed ??? Don't want to replace the whole clutch if that's not the problem.
