Having trouble pinpointing this suspension knocking sound...
OK I have a suspension issue that is a bit strange. When it rains or the undercarriage of the XK is damp I have a fairly consistent knock coming from under the drivers side under hard braking or hard acceleration from a standstill. As far as I can tell it is somewhere around the 2nd row of seats near the outside middle of the car. BUT when the weather dries out (as well as the undercarrage) the sound is diminished significantly. This knocking sound became very apparent during the outing to Flagpole last month. I scheduled an appointment with the dealer but the sound stopped on it's own. But when I scheduled the appointment I could recreate the sound almost on queue. I know realized that the week I got back to town from this trip it was a fairly wet week. But we have had 2-3 weeks dry weather. Because it is raining today I finally made the connection because it is raining again and the sound is back.
Anyone ever experienced this before? Where should I look? I am going to check the upper and lower control arm bolts when the rain stops this week. But when it was dry I crawled up under the XK and could not detect any bare metal that would indicate any major issues. Any suggestions welcome!
