Both mine and my sisters E34 have this "tink-tink-tink" noise as we engeage first and drive off. It sounds like something touching the driveshaft. I put my car up on a lift on Saturday and nothing looks to be touching what so ever.
This noise I have heard on a few E34s.
Checklist:
1) Not guibo, both perfect
2) Not center support bearing, both perfect
3) Not shift linkage touching driveshaft
4) Not heatshield touching driveshaft (don't think)
Anyone know what the hell I am talking about?
