XKR-S - Front Upper Wishbone Rubbers
Discussion
I’ve just had my car serviced (27,000 miles over 5 years) and I got an advisory that the front upper wishbone rubbers are perished and will need replacing soon (they also included a video showing the perished rubbers).
My last car had covered 12,000 miles over about 15 months when I bought it, then I covered another 40,500 miles over the 7 years I owned it and this problem never occurred.
This leads me to think that maybe something isn’t quite right and there maybe an underlying issue that I should get resolved whilst the car is under warranty.
This raises the following questions in my head;
1. Is there a possibility of an underlying issue that has led to this early deterioration?
2. Would this be covered under my 2 year Jaguar warranty?
3. Would buying OEM parts invalidate my warranty?
The research I've done so far indicates that these “rubbers” are not individually replaceable, but are part of the upper wishbone assembly, which comes with a substantial price tag, plus the labour cost to replace it.
The part numbers I’ve found online are:
C2P25603 – Genuine Jaguar Right Front Upper Wishbone (£390-£430)
C2P25604 – Genuine Jaguar Left Front Upper Wishbone (£390-£440)
C2P16948 – OEM Jaguar Right Front Upper Wishbone (£125-£142)
C2P16949 – OEM Jaguar Left Front Upper Wishbone (£125-£142)
As my car is under a 2-year Jaguar warranty, I feel I should use genuine Jaguar parts and the suppliers I have found so far are SNG Barratt, Moss Europe and Brit-Car.
British Parts and Berkshire Jag Components only seem to stock the OEM parts, which are about 1/3 of the price.
I’ve consulted my workshop manual and there seems to be considerable labour involved, namely the removal of the Shock Absorbers, plus the ECM on the left-hand side and the coolant expansion tank on the right-hand side.
Opinions /advice please?

I went through this on my 2008 XK, and my 2005 XJ this year.
The problem is usually the rubber ball-joint boot disintegrating. It looks like Jag changed the boot materiel between my cars (the front and rear wishbones are very similar), as the 2005 versions were in better shape !
Anyway, the ball-joints, or the boots, are not individually replaceable per Jaguar - the whole wishbone needs to be changed. Means removing the shocks and disconnecting the brakes in the rear.
Size 14X31X23mm fitted both my cars. Holding up 6 months so far, on both Jaguars.
The above info is mostly for others, as it looks like the OP is under a Warranty of some kind, so will want OEM replacement parts.
(OEM manufacturer of the wishbones is Lemforder. In the US FCP is a good supplier of these).

- However*, if you catch it early, and the ball-joint is not eroded, there are replacement boots available on EBay.
