Safely support the vehicle and remove the wheel. Unbolt the brake caliper and pad bracket. Leave the brake line connected and hang it off to the side (don't hang it from the brake hose). Remove the brake rotor and the axle nut (should be a 36mm. If your not using an impact gun, this should be removed with the wheel on if possible to stop it from spinning). Disconnect the wheel speed sensor and remove the three bolts securing the wheel bearing. The bearing could then be removed. It may require some persuasion with a hammer. Installation is reverse of removal.

YEP BAD WHEEL BEARING WILL MAKE A ROARING LIKE NOISE WHILE IN MOTION.BAD WHEEL COULD PUT DRAG ON WHEEL WHICH CAUSE ABS LIGHT TO COME ON.YOUR WHEEL BEARING HAS THE WHEEL SPEED SENSOR BUILT INTO IT.SO IF WHEEL BEARING BAD THE WHEEL SPEED SENSOR PART OF ABS BRAKE SYSTEM WILL CAUSE ABS LIGHT TO COME ON IF WHEEL BEARING BAD.MAKE SURE FRONT BRAKE PADS INSTALLED CORRECTLY IF NOT. YOU WILL GET TERRIBLE WHEEL NOISE ALSO.

The car is making a roaring noise going down the road, if I turn the steering wheel to the left it stops, if I turn to the right it gets louder. Any ideas?


Good Morning. What this sounds like is the exact diagnosing of a front hub assembly really not that pricey either, and a common problem. Last one I did a few days ago even with the noise calming down going the other way ended up being both hubs. I hope this helps and if you have any questions please feel free to ask.
Thanks,
Joey

When I drive slow over bumps/speed bumps I hear a noise in the right front wheel well. The car does not seem take bumps well but seems to be better going over them at higher speeds. Shocks? Struts?...


It could be a bad Shock/Strut, Ball Joint or a bad CV Axle. Put the car on a lift and try to move the parts around to try to isolate the noise.

Roaring noise in front of 2003 olds alero gets louder as I accelerate, sounds like manual transmission needing to be shifted to next gear(this isn't a manual transmission


Have a shop look at it. It may just be a failed wheel bearing. The bearing will leave you stranded if it gets bad enough and cause more damage.

Changing front wheel bearing 2003 tiburon how do i get the sensior off so i can take the bracket in to get the old bearing pressed out at the shop


There's one bolt holding the sensor in to the steering knuckle. Remove the bold an pull the sensor out.

When I changed my wheel bearing, the sensor was ceased in place and it broke when I tried to remove it. I had to drill out the bits of sensor that were stuck, then install a new sensor. The new sensor cost around $235.

Alternatively, you could follow the sensor wire to its connector, disconnect the wire and leave the sensor installed. But be aware that the sensor may be damaged when pressing the old wheel bearing out / new one in. In that case, the sensor would have to be replaced anyway.

Replace front wheel bearing is it hard to do on 2002 alero


its actually pretty easy if you have the basic tools needed and a little mechanical knowledge, because i dont think you can buy just the bearing at a auto parts store. they sell you the whole hub assembly which is great for the DIYer.

lift the car off the ground and block it from rolling and place a jack stand under it so it cant fall on anyone.

Replacing front wheel bearing


those are sealed units and are intergrated with the wheel rotor if the bearings are bad they must be replaced and those are dealer only items. labor for each side is about 1 hour for remove and install per side. unfortunately there are no aftermarket parts available just yet. hope this helps
