Grinding noise on acceleration
Hi, first post so sorry if this is in the wrong place. I have an XC90 AWD D5 2009 Auto with 92,000 miles on clock. I have what I can only describe as a grinding noise when accelerating through 1st and 2nd. Also on occasions while cruising at around 50mph there is a shudder from the engine that stops when I lift off the accelerator and then goes. I also think that the rear wheels have no drive so the AWD is not working. The car drives ok but obviously concerned about the noise. Anyone had the same issue or know what the problem is and how to fix it and if possible, an approximate cost?
Thanks in advance, Rob.
