I just had the dealer do my clutch for the third time since the first 2 times they used Napa parts since they couldn't get the Ford parts for some reason. Both times it would chatter in first big time when it got warm outside or when I drove it for awhile. So I made them use Ford parts and do it again for the third time and they had to replace my flywheel too since it couldn't be resurfaced again. Now the problem is that it chatters a little in first when its cold and seems to smooth out when I drive it awhile. I have less than 100 miles on it so I don't know if its something that will go away or if I can do the break in and then give it a good workout and smooth it out. Has anyone experienced this with a new clutch?
