Have a 2007 MKX am now on my second PTU unit.
First repaired after 6000 miles with a new seal.
Brought it back 1 month later after smelling smoke again.
they said they couldn't see anything.
2 weeks later, had it back in again for a new PTU.
3 months later, started to leak again.
Just picked it up from the dealer again! This time they figured out that the axle had slight
scoring on it which ruined a bearing and seal. So New Axle and New PTU. We'll see what happens next.
Are the new 08's having the same problem?
