I have a 2007 XC90, 3.2L awd. I have the new part but I can not budge the two bolts that hold the mount to the frame. Anyone here have any tips on how to get enough leverage on those bolts? Getting ready to take it to a shop.
Appreciate any ideas or help, especially from those of you that may have done this yourselves.
This is the mount I'm referring to -
