So my evo IX has 34k miles, and so far so good. Until today. All of a sudden its making a weird grinding noise when turning right only...for example if I tried to do a small circle going right, it would make a bad rubbing/grinding sound. The problem dosen't look to be visible, though I haven't jacked up the car yet. Also, its weird that it only happens when turning right.

Any ideas?

 

Hmm. Do you race or launch your car at all?

 

Nope, I've been to the 1/4 mile before but never ever launched. I got the car with 6k miles on it, so it may have been launched during that timespan. I do hit it occasionally, but I'm sure I'm not the only Evo driver who actually hits it...

It sounds like it something from the right wheel-area?

 

My guess would be the wheel bearing. I would pull the wheel off and inspect the area for any possible damage.

 

your brake pads may be getting thin too

 

Checked the boots on the front axles to ensure no rips?

 

fender liners?

 

I would check your cv joints and or fender plastic rubbing against your tires. GL

 

mine did the same thing until i got the liners bolted to my new undertray. and it was only on right turns too

 

It is most likely the Wheel Bearing on the car. For instance if you turn right and you hear a noise then you know a bearing is most likely bad on the left. And if you turn Left you wouldn't hear it coming from the same spot. Same thing goes for the other side just switched.

Another way to test for a bad Bearing is to put the car up on a lift. Then Put One hand At 12 and the other at 6 on your tire. Now wobble the tire back and forth. If there is any play then you know it might be the wheel bearing as well.

The same thing happened to my front left Wheel Bearing

 

Wheel bearing isn't going to make noise at low speed. Check to make sure your not rubbing on the fender liners. They can make A LOT of noise if they are rubbing.

 

Check the backing plates are not touching the rotor. If this is you issue bend them back a little

 

in this case my vote goes to spider gears in the diff, or hopefully an axle. Its not really loading the bearing much going in a slow circle but it is making the diff work because of the difference in wheel speeds. Good luck im rooten for the axle lol

 

All you guys are wrong! I hate to say this b/c its extremely embarrassing.....but my lug nuts were loose!!

I had checked them immediately when I heard the noise, and they all seemed fine. After driving back to my apartment I checked them again and noticed I could finger tighten/loosen all on the driver side front tire. After I snugged those up I haven't heard the noise at all.

Luckily I'm so OCD about my car I heard the noise right when it started, so I didn't have a wheel go flying off while doing 100+ down the road.

 

I just replace my left front hub...there was no play at all but it made a lot of noise going straight and when I turned the pitch of the noise would change a bit
