Rear vibrations

[sladdjanne]

I own a 2009 Jaguar XF X250 2.7 V6 (AI-D) and I’m experiencing a strange issue that appears occasionally in the form of vibrations. I’ve noticed that between 40–50 km/h and at low RPMs (especially when going uphill), just before the car needs to downshift, there are quite strong vibrations coming from the rear of the vehicle. The same thing also happens between 70–80 km/h. There are no problems in shifting nor sound from the gearbox, only vibrations from the rear somewhere.

I’ve had it checked at Jaguar, but they couldn’t determine the cause of the problem. A workshop has already replaced the center driveshaft without success.

Has anyone experienced something similar or have an idea what this could be?

Thanks in advance
