So the car has been going great for the last few week....however, the "pinging" sound has returned :( . Sounds like its coming from the right side. I recently replaced the axle bolts with the "anti-ping" bolts p/n 30748388 and the noise disappeared. I checked the bolts and they are torqued to 50nm. Don't want to over torque them as I did that once and sheared the bolt. I suppose my question is:
- do this "anti-ping" bolts have a lifetime (short one at that)?
@ToomanyVolvos has already asked about this. Do they?
- when I replaced them I did not remove the drive shaft, grease splines and put them back in. Could this be the reason that the noise has come back so soon?
- Could it be something else e.g. drive shaft failure? Noise is definately on the right side. The boots look intact with no loss of grease. Is there a way of telling if shaft is ok without completely removing it?
Cheers!
