Bentley book says to replace the motor mount bolts (it says to replace almost every bolt  )
What I had noticed is they are easy to break, and newer bolts (the ones with hex head not e-torx) are specially made to break on stress.
The torque spec on them are not very high either 28 Nm (20.6 ft lbs). It may have been fatiqued during tightening and then snap after a while. I suggest using torque wrench on them.
The subframe bolts are not mentioned to be replaced in the Bentley from what I remember. They are hefty bolts and not torqued to yield. I reused mine other than the middle one at passenger side which was badly rusted in the middle section, making it thinner there. It may be an XI frame issue trapping water right there. |
Thanks PhaseP for adding that info. I guess I should invest in a manual considering what I spend on the car.
