Folks: Apparently if your X is made before Apr 24 2019, the clevis mount (frequently referred to as the motor mount) on the front drive unit is a major cause of shudder problems. as it does not secure the drive unit properly. See: https://cdn.motor1.com/pdf-files/sb-21-39-001-replace-front-drive-unit-halfshafts.pdf and the explanation on page 4 showing how to determine what version of the clevis mount your X has. Although I have no issues with shudder (I drive mostly in Low), I intend to do the upgrade to the new clevis mount version to keep my car current and hopefully avoid future problems. I do a lot of maintenance on my cars myself. I have two questions:
1. Has anyone changed the clevis mount themselves and what is the degree of difficulty? Among other things one has to support the drive unit while R&R the mount.
2. Is it absolutely necessary to change the drive half shafts (CV axles)? Mine are just fine so I don't see the point.
Thanks in advance to all that respond.
