My 2002 147 2.0 with 120,000k on it has womp womp womp rotational sound that varies with speed. I suspected a bad tyre but after replacing all 4 tyres the sound is the same. I also got an alignment done (a few days earlier), which if anything made the noise worse.
So I spent some time on the car yesterday, looking for the front end. Jacked up both sides and identified that the front right is making all sorts of noise. When I spin the wheel I can hear some clicking/grumbling noises, like the balls are loose in the bearing and if I hold the knuckle and spin the wheel, it feels rough not smooth. No noticeably play in the wheel.
However I am not sure if it is CV or wheel bearing causing the problem.
The CV boot is intact and seems OK (same on both sides) but I haven't had the car long, so the previous owner could have replaced the boots A test drive and some tight circles doesn't cause the CV to click or rumble on either side. There is a very very (barely noticeable) hum when cornering hard left.
When driving at normal speed the womp womp womp noise is pretty constant (braking, costing or accelerating) although perhaps gets quieter when accelerating but that could be my imagination or the fact that the engine is loader and masks it
What do you think? Bearing or CV?
