pathfinder123 Posted July 26, 2009 Share Posted July 26, 2009 I have had my 08 Coupe for about 3 months, and recently I have been trying to track down a noise coming from the rear on the passengers side. It seems to happen only after I have been driving the car for a while, an is more likely to happen when the weather is hot. It is a tapping sound that occurs when I go over bumps. I have been all around the inside of the back of the car making sure that all the plasticey bits were solid and applying felt where things were rubbing. Although this process has got rid of a lot of squeaks, the tapping sound remains. Something I noticed the other day, was that after I had opened and closed the trunk the tapping seemed to go away. That reminded me of a Focus I had that developed a knocking at the back which I traced to a defective pneumatic stay. That one was very noticeably bad, but I was wondering if one on it's way out could be the cause of the tapping. I am thinking of swapping the LH and RH stays and seeing if the problem moves. Has anyone else experienced this type of noise or has changed a stay - is it easy, any tips. Cheers S. Quote Link to comment Share on other sites More sharing options...
srobrien Posted July 26, 2009 Share Posted July 26, 2009 I get this sometimes but its the plastic trunk cover/mesh thing attached to the lid rattling may be the same problem. Remove it and see if its still rattling. R Quote Link to comment Share on other sites More sharing options...
pathfinder123 Posted July 27, 2009 Author Share Posted July 27, 2009 That's a good thought R. I will try that as well. The difficulty is that the problem is so intermittent. S. Quote Link to comment Share on other sites More sharing options...
pathfinder123 Posted July 27, 2009 Author Share Posted July 27, 2009 I was going to swap over the left and right trunk stays, until I noticed that they were marked LH & RH. They look identical. Anyone any ideas ? S. Quote Link to comment Share on other sites More sharing options...

S. From what we hear undoing the stay bolts can be a nightmare anyway As srobrien says, check that small tonneau or it could be possibly be the counter balance weight behind the lid lining or perhaps the wiring srving the rear wiper motor if you think that is the area it is coming from. You sure it is not something loose in the large glovebox? Its also not unknown for a bolt or similar to in the floor area (dropped when building the car) - and noting your car is relatively new. May be worth checking all around the spare wheel area Quote Link to comment Share on other sites More sharing options...
pathfinder123 Posted July 27, 2009 Author Share Posted July 27, 2009 Thanks for the tips guys. Are the stay bolts put in real tight, or is there some locking solution on them ? Looking again at the stays, I think that unlike others I have seen the piston and the body may not be able to rotate through 360 degrees, so that may be why they are handed. The small tonneau cover has a couple of tangs on it's front end that locate into the underside cover of the hatch. I found that there is quite a bit of up and down movement possible. Not sure that this is the problem, but it might cause tapping when the various bit get hot and start the expand. I have put some heat shrink sleeving over the tangs, and now there is no movement. I guess that it's just trying one thing after another until the tapping goes. S. Quote Link to comment Share on other sites More sharing options...
pathfinder123 Posted July 29, 2009 Author Share Posted July 29, 2009 Went for a fairly long drive yesterday and no tapping noise, so I'm keeping my fingers crossed that I've found the cause. Certainly the amount of play on the small tonneau cover tangs was not good, and remains the major suspect. Putting heat shink sleeving over them was a quick fix for some if not all the noise. S.
