I've noticed that as soon as I've fixed a problem like a knackered UJ, the fact that I can't hear it clanking anymore allows me to hear another problem on the go; I find turning the volume up on the stereo tends to fix most of 'em!!
I dont believe in this phenomenon however i do have atheory of my own, if it starts to rain whilst you are working on your Landrover/other vehicle. then its usually a good sign that things are going well, if it doesnt rain your screwed
Well, actually, I spose I have got 2 faults at the mo, if you define "serious" as potential MOT failure points. Me andbrake needs adjustin and me clutch peddle rubber as gone awol.
