Theres a road noise like a humming that increases with speed and becomes noticeable above 40mph. The noise does change when I turn the wheel when I turn towards the left it kinda has a grinding feel to it, if i turn to the right it feels smooth

It seems to be inflated, havent tried rotating the tires, could it be out of balance or alignment is way off, theres been alot of snow maybe something is stuck in there?

Braking seems to be normal so I wouldnt think its a warped rotor or anything like that

I'm kinda clueless on this problem as I've never experienced anything like it before, any ideas here?

 

wheel bearing mang

 

wheel bearing

 

This. Mine just went not too long ago, same exact problems as described. I ignored it for a while until i got too annoying to drive, a new ones a few hundred bucks + install

 

car seems a bit young for that

 

its a cobalt

 

if indeed it is a wheel bearing i should be able to jack the car up and there should be some play in the wheel correct?

 

correct jack it up. grab the tire and wiggle left to right you will feel play. there should be no play at all. also spin the wheel and hold onto the spring you should feel the vibration from the wheel bearing.

 

Is that a bitch to replace on your own? I'm thinking that might be the cause of my vibration in the right front.

 

my 06 needed both within 5000 miles of each other. car had 106K when i did the first and just over 110 for the second. easy to do.

 

Damn! I have this same issue.... ugh..

 

i replaced mine in the rear. the fronts i believe you need a press in order to put the bearing in and take it out.

 

are they like the cav? you take off the rotor and caliper and there was 3 torx bits and it pulled right off

 

I'm in for an answer. I'm tired of this vibration

 

i believe there pressed in but i could be wrong

 

if u turn left and it gets louder its your right front bearing, it comes as a complete hub

 

They aren't pressed in but if you live in a place like new england with salt and crap on the roads... it'll be corroded to the knuckle. I had to use an arbor press to get the thing to break free out of the knuckle. Once I got it out, I sand blasted the knuckle and slipped the new one in. I used a Timken bearing, set me back like $130.

should give you a idea of whats involved in replacing pretty easy

 

ahh good to know! thanks cleared that one up i thought it was the press fit one

 

so parts master, national or timken, is there really a difference? all those are like 70 less than the AC delco ones im seeing

 

Check your axles as well. could be a CV going bad.

Otherwise a hub is a pretty easy job on these cars. Hardest part is getting the axle nut off.

 

I got an impact gun, shouldnt be that bad

 

Then you're all set, and it's a pretty straight forward job.

 

Im having an aweful time trying to get the right part number theres 3 of them on ac delco that say they are all the right ones

 

Call up Tom at CED in the morning, he'll get you squared away.
