My 2011 XC90 V8, has developed a slight vibration when strong throttle that gets worse has the revs go up.
once it gets to 5000rpm it gets worst.
i took it to bc a Volvo mechanic who advised the best thing to do is a transmission flush. This was completed however, the slight vibration is still there... so I was thinking it may be the cv joints or the front axel..... the issue it isn’t always there on certain throttle so it hard to pin point it as being the cv of the front axel... after reading other comments in this forum I have heard someone mention lower engine mounts.... could this be a solution to fix it ....
