2000 Jaguar XJ8 V8 Two Wheel Drive Automatic 79000 miles
Have this strange noise when swerving or driving over the raised gutter into my driveway at home. Sounds like a dull thunk and I swear it is under the dash. My mechanic thought it was outside near firewall. They searched, couldn't find anything. Quite obvious when it happens. I can make it thunk by swerving the car sharply right to left or vice versa. Mechanic checked sway bar, frame, firewall area - nothing. To me it almost sounds like something inside the duct work under dash, kind of like a trap door closing. Weird, any thoughts?
Also where in the heck is the cabin air filter located?

As a result of ongoing quality improvements, Jaguar Cars has identified an opportunity to address a potential concern on a number of vehicles within the above VIN range, whereby the lower wishbone bushings in the front arms may split.
Analysis has confirmed vehicles manufactured after February 2000 are less likely to exhibit this concern due to manufacturing improvements to parts used from that date. Therefore, this action is only applicable to vehicles within the above VIN range.
The latest specification replacement parts for the wishbone front arm bushings are:
XK Series vehicles - MNE 1360CA
V8 XJ Series vehicles - MNE 1360BB
Jaguar Cars is aware that dealers have been using the rear wishbone bushing MNE 1360BB in place of MNE 1360AB in the Front Lower Wishbone on V8 XJ vehicles for some time. If, after inspection of the vehicle, it is determined that MNE 1360BB is already in place, replacement is not required.
On XK vehicles you should check DDW or any other Warranty/Service information that you have access to, to ensure that the front arm bushings have not already been replaced with the latest level parts (MNE 1360CA) prior to carrying out this Service Action.
NOTE:This Service Action details the inspection and possible replacement of both wishbone front arm bushings. This policy applies to vehicles affected by this Service Action only.
To ensure that the performance of the front lower wishbone bushings on the vehicles within the above VIN ranges is maintained to the latest level, inspect and, if necessary , replace the lower wishbone front arm bushings at the next service opportunity.
VISUAL INSPECTION OF BUSHINGS
To be carried out on XJ Series vehicles only to identify the level of bushing fitted.
NOTE:This method cannot be used on XK vehicles since the MNE 1360BB and MNE 1360CA bushing cannot be distinguished visually.
