Hi all,

My XK 4.2 has developed a major squeak coming from the rear left side.
It is seriously loud when the car is in motion but also If I press the car down from the boot.
I tried to locate the exact source of squeak but can't. I have applied some silicone spray in parts to see if that made any difference but no success.
Strangely though when I placed the car on the jack on that side, it didn't squeak when lifted up or down but it definitely comes from near the rear left suspension.
Any idea what I could try before trip top garage? (would rather avoid expensive changes as I'm planning to part ex the car shortly ...)

Thanks

 

coil or shock at a guess

 

My 5.0L 2010 XKR has developed the same squeak at the rear. And getting in or out of the car or pushing on the bonnet can recreate the sound. I put new shocks in not that long ago. I'm guessing maybe something with the muffler hangers. I will be taking a look later this week.

 

I had an annoying squeak from the NSR on my 2007 XK. Eventually traced it to one of the Upper Wishbone bushes.





The bushes are available but I put a full Wishbone on for speed.




My first thought had been Damper which was the more likely source.

Thanks a lot. Before changing it did you try something to attenuate the noise?
As I said I want to trade my car at a dealer (who will most likely put ut uo for auction) for a new one so I'd like to avoid expensive repairs now if at all possible...
How much is it to change a Wishbone?

 

The yellow sleeve is a piece of hosepipe over the park brake cable. I thought at the time the loud and annoying squeak could have been from the cable rubbing against the triangular (OE) rubber or the damper spring.

Next I removed each upper wishbone pivot bolt and lubed with anti-seize. This did reduce the squeak but did not eliminate it which is how I eventually sourced it to the bush.

The bush cost me 120 UKP six years ago. I'd expected the swap to be straightforward but the flexi brake hose has to be removed from the caliper (it passes through the wishbone). The copper crush washers aren't re-useable.
