anybody know what the little hose under water pump is for and should it be hooked to anything?? it heads toward the oil filter and just dangles there. another thing is just put on a newn front tire "avon" and now i have the slightest "ticking, zzzzzzz, faint card in the spokes sound, slows down when i do and doesnt change under braking or weaving back and forth. I check bearings when wheell was off and seemed ok and torqued to specs, what the @#$% gives.
