I have now sailed past 170,000 and nine years of totally satisfying motoring and now heading for a second cam belt change and a big service. But for the last 5000 miles I have had an increasingly noticeable noise coming from the front, possibly off-side wheel area. It is a constant drone or whine that I hear from 20 - 70 mph. It gets higher in pitch the faster I go and is not affected by steering or brakes. It is sometimes slightly pulsating. Not intrusive, you can’t hear it with radio on or on noisy rough surfaces. I’m not brilliant mechanically, but it sounds like it might be expensive? I have totally received full value for what I paid for the car in 2010 and it’s trade in value is pretty much zilch so despite loving the car I’m not keen to invest 000’s on it at this stage. Do any of you experts think I’m worrying unnecessarily because there is something obvious and cheap to fix that I’m missing? I’d love to still be driving through 200k. I’d be very grateful for any thoughts.
