I was just on NJMP lightning today and on my way home I'm hearing like an airplane sound coming from the right side of the car...

since lightning has only two left turns, I was doing alot of right turns..
could my wheel bearings be on their way out? or could it be the balljoints? I have never heard this sound I didnt hear it when i was on track.. the sound is more pronounced when turning right..

anyone experience this? what should I replace? thanks

I've had aftermarket wheels (motorsport) rub against my wilwood calipers when in turns that sound similar to cards in the spokes of bicycles. But since you didn't hear it at the track, I have no idea. I suppose you may find the source after more investigation if you look at the whole suspension/chassis setup.

Hard to know what "like an airplane sound" sounds like, but I would guess that you have a failed wheel bearing on the right side of the car.

Jack the car up on the right side to get both tires off the ground. Grab the tire at the top and the bottom. Pull on the top while pushing on the bottom, then do vice versa, a few times. If you can feel a slight movement, then that bearing is definitely bad. If not, there still is a small possibility of a bad bearing, but probably not. Repeat for the other right side tire.

another vote for bearing, mine was making the "airplane" sound (accurate description, actually) long before I could feel any play.

better test is to take the wheel off and just rotate the hub by hand - if it does not rotate smoothly, it's going.

Mine and a buddies both sounded like a low pitched hum, before being able to actually feel it, and when turning.
My vote is for the bearing

also,
I just had a complete left rear hub failure at Putnam about 3 weeks ago. Bearing was fine but hub completely separated.
I thought the tranny or something let loose but replaced the bearing and everything was fine.
If it had been the front, the wheel would have come off.

I knew it was the wheel hub bearings... thats the only thing that makes sense.. I will check the car tomorrow and see if there is play in the wheel.. Im going to replace the whole right side, front and rear.. the left is quiet..

its funny because the car still is performing normally..

and it sounds like a hearing a small airplane pass by up in the sky... the pitch gets higher the faster you go and past 100 it is bairly audible because the whine is high pitched.. that is why I did not hear it on the track...

You might consider the newer, stronger SKF bearing. That seems to be the bearing of choice for the track. Be aware there are two different flavors of SKF from what I understand. Get the stronger one.

Interesting short video of HD SKF hub. It's amazing what having more ***** will do!

Yep. It is better no matter how you 'spin' it.

yeah I looked at the SKF's... they are three times the price.. the stock ones last me for about a year and ahalf.. I use Nitto r2's if i was using hoosier's I probably would consider it.. I get them for 160 apiece at rockauto...
