Ah, the headlight lens - I already superglued that to stop it vibrating, thats an old classic problem that I had with a TP1 years ago when I had one from new. The wheel glamour cap on my TP1 is another area of rattle as well, but we already discussed the missing washers on the wheel inner side being the initial cause of this problem, but despite adding a nice large washer, the glamour cap still vibrates, funnily enough, moreso on the backwards stroke. The problem is I am a bit of a perfectionist with my cleaners and like them to work as they would from the factory brand new, sadly I think my TP1 is never going to be as new again, and I must put up with its annoying vibrations and rattles. I will buy some new brushroll bearings though as these still seem to be available, and my Ranger needs them as well. Lets see if new brushroll bearings help with the noise. The motor bearings in my TP1 are fine, I checked them when I had the cleaner apart for full cleaning and inspection when I first acquired it.
