XKR Vibration at 70 MPH
Hello all. I have a 2004 XKR with 67k miles. I developed a steering wheel vibration following some repair work. The vibration is fairly severe and occurs at about 70 mph. If I let off the accelerator, it goes away. It is not affected by braking. The work I had done included replacement of rear brake pads and rotors, replacement of left ride height sensor, replaced both outer tie rod ends, replaced supercharger and serpentine belts, replaced front level sensor, four wheel alignment, replaced front shocks and upper shock mounts, replaced front antisway bar links, and oil/filter change. As stated the vibration did not occur prior to the work being performed. I just purchased the car and drove it about 350 miles after purchase with no vibration. Any ideas of where to start troubleshooting? The shop suggests the road force balancing but that doesn't make much sense as no work was done on tires. Thanks for any help on this matter. This is my first Jag and I already have about 6k worth of repairs, not ready to give up on this work of art!

Sorry but it seems downright negligent to have not balanced the tires while they were off the car for such an extensive repair list. Surprised your shop would even allow that.
Anything could have happened while the tires were off. Perhaps one lost a weight. I would do the balance with proper tire pressures and see where you end up after.
Probably should have done the upper control arm bushings while you that deep into the front suspension. However those are easily doable with removing the struts later.
These cars are finicky about alignment/balance. But once it is right the ride is glorious. I am confident you will get it sorted.
Nice car choice too though I am a bit biased.
Not many R models in that salsa red color. Its a keeper.
