Volvo TMD22 Engine Mounts,
Did you also replace the C Drive rubber bushing. If you had a lot of vibration it will have been affected too. It is a half hour job.
I don’t think mine had ever been replaced and was the cause of my mystery vibration.
It’s now on my check list when I change the prop shaft bushings.
