Recently got at 06 HSE 4.4 Jag V8, and coming from the P38 im amazed at how modern and civilized this vehicle is in comparison. However, been trying to track down this sort of humming/grinding noise at low speed when accelerating lightly or coasting on smooth roads. I can feel it on the steering wheel, throttle pedal and the shifter if i touch it. Its a high frequency vibration. Ive done things that helped a bit like replace the front wheels bearings, drained the two diffs (F+R) and switched to 19in factory wheels from the previous 20's SC wheels. They helped reduce the noise/vibration but hasnt totally eliminated it. Generally the car drives very nice and im so happy....but i get a feeling something is amiss.

Anyone? 06 FFRR HSE

Does the car shift smoothly? I would probably get the car checked out by a mechanic. Could be something as simple as the engine mount boots (can't remember the proper term, the rubber boots the engine sits on) being worn. On my last car, this took about 30 minutes to replace and about £45 for parts.

What tyre pressures you running?

Welcome Phil - sorry but I cant throw any light on this  '09 Freelander 2 TD4 HSE Auto for the Mrs

Using the works Fiesta 1.6 TDCI Sport Van - CHROME FREE THOUGH

Searching for a nice E63 AMG or S8 V10 to replace my "wonky" TDV8

Thought of the engine mounts too but my car has only done 26k kms although i havent visually inspected them. Has anyone here have their engine/transmission mounts on a Jag engine fail prematurely?

As far as the tire pressures, we have really bad roads and mostly stop and go driving in traffic in very hot weather so i run my tires a bit softer at 34 front and 38 rear. Its gets really jarring if i air it to specs. 06 FFRR HSE
