Any of you guys notice this on your LLY?? Seems to be around cruising speed (50-60mph) ~1600-2000 rpm...Almost sounds to me like a squeeky bearing in the turbo (although I doubt it) Sound is too far back to be the belt....Any ideas? It's starting to really drive me nuts, and I know I'll get the usual bonehead look from the local dealer..http://www.dieselplace.com/forum/smileys/Question.gif


Thanks in advance.....

Mine is going in tomorrow for this problem.

The squeak is a chirp. About 15,000 primary with a 2 hz modulation
and a 2 second time.

Get to 1000 RPM in 4th gear on a quiet road, lift throttle and then
tap on the go pedal. It will chirp chirp chirp every time.
