basically ever since i got my tires rotated a 2nd time, the usual way front to back and back to front, my car has sounded like a blackhawk chopper while crusing on the highway. i know during the summer, when the AC is on, our cars sound like a harrier jet, pretty loud, but this time while driving i hear audible sounds coming from the front, almost like a plop plop plop, but to the bassy interval of what a helicopter would make. It's not a creaking or groaning, or a wob wob, Both axles were replaced (Raxles), meyle Hd outer TRE's, brand new meyle front sway bar links. Upper and lower control arms are still stock but still look good. Plenty of Pentosin CHF-11S fluid, new brake fluid, so i'm left thinking it has something to do with the tires. How often do you rotate your tires? My indy told me 1st interval would be ~ 5k, then every other oil change after that or follow the built in Falken rotation wear indicators.
here's the setup:
99 1.8T Tip FWD
B6 17'' Audi 5 Spoke Sport Rim
UHP Falken 912 - 235/45/17 (purchased/mounted/balanced - Aug 07)
Tire Pressure - 37~36Fronts and 35~34 Rear
currently 17,000 miles on them.
1st rotation done @ 5270 miles LF to LR and RF to RR (May 08)
2nd rotation done @ 11280 miles LF to LR and RF to RR (Feb 09)
Can i eliminate this noise at all? or am i stuck with it for the remaining life of the tires? Would it matter if i rotate them back to where they were before? i purchased the extended/replacement warranty on the tires, 100% replacement w/i 1st year, 75% 2nd year, so on and so forth. being i am on my 2nd year if i get them replaced, i would shell out 25% cost of each tire + re-mounting/balancing, should i just get a new set? Any advice inputs would be greatly appreciated. TIA
