Everything here is off the top of my head, hopefully others will chime in.For example with s40s we should look at the upper radiator hose (known leak spot)
Motor mounts and lower control arms for one Ok the entire suspension lol...
Still learning the xc70 but it was a cert preowned.. Still under warranty.. So nothing to do yet
Here's what I can report based on experience with a 2010 T6... now at 94K miles and owned for about 5 years since about 48K miles.What are some things that I should be looking at?
Usually just the 3.2 FWD
But I have seen some T6 AWD..
I currently have 2006 S40 and 2015.5 XC70
That's about what mine sounded like... although I never heard it from outside the car, it was an obvious whine at maybe 60 mph or so from inside the car. Cost for new unit at Volvo dealer was about $5700 installed. Had an indie quote for about $7200 for new, installed. Dealer install has lifetime warranty to owner at time of replacement.
My XC60 does this. Has something to do with the shifter cable vibrating. There is a TSB on it to install a vibration dampener. I’ll try to find it. Nothing to worry about though.I'm thinking it's torque converter or rear diff. But the sound is there for about 2 years and everything is the same.
Sound is only in 6th gear at certain speed. When car is in 5th gear and in same speed no sound.
