Jacked the car up to have a look for anything causing the annoying rattle I have. Iund a couple of loose bolts securing the front under tray. Gave them a rattle and from the sound I think I've found the problem. Have the underneath of the duff a good going over with some acf50. As can be seen from the below pictures, my prop shaft nipples were on show so gave the from 2 a couple of squirts each. Don't think I got anything in to the rear one as there was quite a bit of resistance, and didn't want to force it. Is this resistance normal?
