I had heard it once in a while but assumed it was just road texture. The issue has become much more pronounced lately so I assume my tires have worn to a point that it’s accentuating whatever in the car is resonating, making it worse.
Or maybe pop on some headphones.
I hear it, but I don't think it's out of the ordinary. I just replaced my tires after being on the car for 5 years and about 40k. The new ones are exponentially quieter than the ones I replaced (same tire, just the newer version). They all get louder as they wear unless maybe the cushiest of touring tires.Y’all are straight deaf if you can’t hear that hum
That's just not acceptable noise. Maybe in a Honda Fit or a 90s Tercel. But not a car at this price point. I will try some sound damping in the wheel wells (I already added some in the hatch, under the rear seats, and on part of the subframe). There's gotta be something resonating that can be quieted down. After that, all that's left is to try different tires I guess (these aren't even 10k mi old).
Yeah the expansion joint humming/ringing is not the most abnormal part. But the fact that the same frequency hum occurs on multiple road surfaces at multiple speeds (including below 25mph), is really strange and kinda janky. It's something resonating that the VW engineers didn't bother to address. I can hear it throughout most of that test drive video.
Lol it's a souped up Golf for high 20's/low 30k. Idk how many miles you have but in a couple more years it'll be a 10 year old car. Not exactly the pinnacle of luxury.
I think it's reasonable to expect a little better than the road noise of cars 2/3 the price (and 500 lbs lighter).
There are a bunch of part numbers for springs for the various models, so make sure you get a matching set for the rear or figure out which ones, with color dots (I may be thinking of the front on that), that you have exactly.One thing I keep coming back to when I’m under the car is that left rear spring though. It definitely rings and hums at the same pitch. If I tap on any part of the left rear suspension, it makes the spring ring and hum. Grabbing the spring stops it. I might get ahold of another OEM spring for comparison if this additional deadening doesn’t do the trick. Or maybe try a set of the 034 spring sleeves (https://www.034motorsport.com/coil-spring-sleeves.html).
Did you have any part numbers printed or engraved on your springs? Or did you just go by the dot colors
I believe that it's a small white tag on the springs.
