Hey guys I have a 1991 crx and it has a bad humming sound on the right side of the car while driving. The sounds increases as I drive faster. It doesnt matter whether I'm in any certain gear, neutral, or on/off the brakes. It sounds very similar to a wheel bearing but isn't since I replaced almost everything on the right side including: skunk2 upper control arms (includes new upper ball joint), lower control arms, lower ball joints, wheel bearing, hub, caliper, brakes and the axle. I'm pretty much at a loss of ideas now and can't figure this one out hoping someone has run into this problem and could help me out because I absolutely hate driving it like this. Thanks in advanced...

 

maybe ur rubbing in the wheel well.i thought i wasnt but i was.or maybe tires are out of line. (2 cents)

 

u got after market motor mounts? soild inserts? they make vibration go up and can cause this

 

Oops sorry I forgot to mention I got an alignment too. Also the tires have been on there since October with no issues and the sound just came up fairly recently.

 

I do have after market mounts but I've been driving the car since august when I finshed putting the car together, without any problems with them, and they are still in great shape.

 

maybe your brakes are rubbing cuz there warn

 

worn*

 

if you have a/c and heater etc etc check if those boxes are loose. also anythin under the hood. or even your door panels. sounds weird but my door panels used to rattle alot. are your speakers bolted down all the way? fenders? hood?!?!?

 

I eliminated that option brand spanking new brakes.

 

All those are good its not a rattling sound but a LOUD humming sound like a reallllyyyy bad wheel bearing. The sound has something to do with moving components because it increases or decreases by the rotation of the wheels moving.

 

Have you tried swapping to another set of wheels? Maybe they're not correctly balanced.

 

did you replace both the front and rear hubs or just the front hub, cause i had a similar noise in my car and it turned out to be coming from the rear wheel bearings

 

Check the splash guard, one of mine got bent out of shape which caused it to rub the rotor and it made a squeaky kind of noise.

 

Yep i've tried that and still not luck
I only replaced the front but I can tell its deffinatly coming from the front.
If you mean the brake dust shield yep its deffintaly not that. I know that sound and it's the nasty squeak. This is a deep humming.

I'm going to a friends performance shop on wednesday night to put it in the air and see if we can firgure out where the sound is coming from while the wheels are moving. But something to know what to look for would be helpful..anyone else????

 

wheel bearings good?

 

yep brand new..i went through 3 thinking they all must of been defective..but after they came out they were mint so thats a negative.

 

well **** i guess wait till Wednesday

 

just a side note.i had taken my car to school and told my teacher about a noise he let me put it on a lift and it ended up being that my axle is kinda bent (wobbling)

 

Anybody else have any ideas???

 

dude i got the same damn noise, but when im turning left or hitting a curb to the left it stops a lil bit but, it is still there i tried everything too.
im trying out everything too

 

Could be the bearings in the alternator. Sounds a lot like what your describing.

 

NO. Read his description. He said that the noise gets louder with SPEED not RPM. My guess is a splash guard is hitting the ground while driving. Something stupid like that is happening.

 

axles? wheel bearings? tranny? Bushings? just throwing out things to check.lol

 

Fixed the problem today. Replaced the driver's side wheel bearing and the sound went away..pshh go figure. Both wheel bearings and a hub go at the same time.

 

was it the front or rear? mine sounded like it was passenger rear, I took everything apart to find that it was the driver's side rear
