Whats up folks ? I have a 2005 LS auto 2.2 with 184,000ish miles (I know thats alot ha ha ) well anyway I have been feeling this vibration in my steering wheel and floorboards throughout all driving speeds , doesnt matter if I'm coasting or giving her gas . Heres what I have done to address the problem to no avail . Rotated and balanced tires .Put a passenger side ball joint on because the tire guy said it was bad . jacked up the car and put it on jackstands and grabbed the tire at 12 and 6 and jerked it in and out checking for play in the hub.. (there was none that I can tell ) also I have replaced the sway bar bushings with Moogs and also put Moog endlinks on her . and I bought some oem control arm bushings and replaced both sides .. Idk where to go from here other then to rebuild the whole damn front suspension lol. I went to a local salvage yard and pulled a rack n pinion with tierod ends and steering universals off a 08 LT 4 door low milage rollover. any pointers on putting that rack in would be appreciated as I dont want to ruin the clock spring or have the steering wheel off center... Sorry So long of a post but I wanted to put as much info as I could .. also my brakes pulsate so I know the rotors are spanked but figure thats not related because it vibrates when driving as well as braking.. So what do you guys think it is ? hubs? axle?

At that high mileage you might have one of your inner axles tripod worn to the point that it's out of center. Or bent axle. If vibration is there at all speeds I would look at axles definitely. Do you here crunching noise while turning at low speed? Then CV joint might be the culprit.

no clicking or poping . just vibrations . Im leaning towards axles myself..I'm going to do some research on how to go about checking the axles.. personally never done a CV or axle .. but that dont mean I cant learn how to ..

Hard to tell while still on car unless it is really worn out bad then it will have play. Pretty simple actually, just a dirty job. Disconnect lower balljoint and outer tie rod. Unbolt big nut on axle. Air ram the axle loose, pull it out of hub then pull it out of transmission (just has a pressure clip). If joints don't move smoothly there's your culprit.

If you have access to a hoist start engine,put it in gear and watch if axles wobble.

I am going to rip into the frontend tonight and let you guys know what I find .. Thanks for the replys .. Im going to rotate the tires and make sure a rim is not bent (had it happen on this balt a few months ago)If that dont find the problem its off with the axles... It would b nice to have GM help out but the problem is Im layed off right now and cant afford to pay a garage 60+ dollars a hour to throw parts at my car .. If Its something I can't fix then I will just run it into the ground

This may sound farfetched, but I had the same problem with my car. My tires only had about 3/32 tread remaining and my valve stem was leaking so I would occasionally drive on it while it was low. I was bored at work one day and pulled the tire off and on the inside and outside of the tire a ring of rubber was worn off from where I was driving it when it was low, I tried balancing it and the problem was still there. If you can feel the vibration in your steering wheel try rotating your tires and see if the vibration goes to the back of the car (or vice versa). Good luck!

Thanks for the replys guys . I havent had the time or money to do anything about it yet, but plan on checking it out very soon . I checked the hubs (thats the wheel bearing on the balt ) its a sealed unit . Im Starting to thing its the hubs going because I never had a axle fail and I beat my cars/trucks..

OK so a few days ago I went to a salvage yard and pulled a used hub off a cobalt . I looked around forever and found on that was ABS .Payed 30 bucks ,seemed fine , I got home and took the hubs off both sides of my car to turn them by hand and see if they were going . The drivers side seemed dry and made a cuff sound when you turned it . Passengers side hub seemed a little better but not much ,so I decided I was going to replace the driver side hub with the one I pulled from the salvage yard. I bolted the new (used) hub on and then I went to throw the rotor on and what do you know, I got a 5 lug hub for my 4 lug Cobalt!!!! I felt like lowering the car down on my head at that point .Well anyway I think its the hubs . So today I went to a different auto recycle place and bought two used 4 lug ABS hubs for 106.00 . I went to a friends garage and replaced only the drivers side hub and rotated the tires also . The tires that are on the front of the car now are like 80% and the tires that are on the back are like 50% or so and I noticed that they have a wear line on the very inside edge of the tires . So I finish the job and drive home .1 minute down the road The TC and ABS lights pop on . Seems alot better now I think otherwise. This sucks now I have to take the hub back off . swap it out with the other used one I bought and hope that works , return the bad one .. Man all this wrenching . (I am assuming the sensor on this used hub is no good and throwing the TC and ABS lights ) So Idk if its the tires doing this or the hub was or what the hell is going on at this point . I just feels all over the place at times .Not to meantion the famous rattle .. I guess my steering shaft is toast also, I can hear the rattle when I hit my brakes or If I hit bumps in the road .



Fun Fun
