8sumthin ea1 4x hatch. how can you tell. i know the ball joint is bad, and im going to replace that, but i suspect a bearing is messed up too, because it grinds, like a flatspot in a bearing, while rolling, but not when you spin it in the air. but last time i thought this on my 2x the bearing looked fine when i got it off. and at something like $60 a side, at napa, i dont want to go throwing parts at it.

oh yeah... on the highway if i turn towards the direction of the noise it gets quiet for a second. front passenger.

thanks

the reason it won't make any nose when it's in the air is cause there's no pressure on it but i'd try the balljoint first because the balljoint could be shifting when you turn the wheel

before you shot gut some parts.

 

lift the wheel of the ground enough to fit a bar or pipe under the wheel. take the long bar or pipe and pry up under the wheel. watch the ball joint while doing this. if it moves a good bit its bad if it just barely moves it probably ok. usually a bad ball joint will give you clunking when driving over bumps.

 

the wheel bearing you have to recognize the sound. It may be like a drone that changes with speed and turning. if it is bad enough there will also be play when wigling the wheel. you are correct about not being able to detect it by spining the wheel unless it is really bad.

 

you say it sounds like a grinding noise? check the backing plate. makesure its not touching the rotor.

i can feel it in the wheel, and the floorboard, the grind at lower speeds. theres some shaking at higher speeds. visually i can see the ball joint moving, and the boot is torn and rust is showing inside whoohoo!

any cheap sources on bearings?

not to thread jack but I too must replace my drivers side ball joint on the front of my rx. I makes a clunking sound when I hit bumps. Kinda has a whining at highway speeds but I think it is just because of the phat tires.

Actually - sounds like both the bearings and the ball joints. The ball joint will cause you to be able to "steer" the car with the go pedal. Gas steers one way, brake steers the other. But a bad ball joint alone would not make a whining noise. That's front wheel bearings when you say "it stops whining when I steer one direction"

 

Napa has front bearings for $12 or so - ask for the "other brand" their premium ones are like $22. You need 2 per side - inner and outer, so 4 total for the front. They are pressed in, and are supposed to be installed with a press. You can do it with a punch if your careful - it's not fun tho.

if Barco Bearing is still alive they are on 26th by the bowling lanes....

 

ask for a trailer bearing: set 10 = 3.00

ask for a older VW front wheel bearing: set 10 = 15.00

ask for a saab rear wheel bearing: set 10 = 40.00

 

all same part number.....

 

ask for bearings by part number :^ )

well, your grinding sound that changes tone/goes away while turning, is most deffinitely a wheel bearing.. had to replace one on my hatch that was doin the same thing..
