Drive Train Axles Bearings problem
2006 Saturn Ion 4 cyl Front Wheel Drive Automatic 60,000 miles

I have a 2006 Saturn Ion 2 with the CVT Transmission. While driving there is a grinding noise the increases frequency and gets louder the faster I go, it is directly related to vehicle road speed. I replaced the drivers side wheel bearing, but the noise is still present. During my initial inspection I inspected ball joints, tie rod ends, axles, and wheel bearings. The thing that really confuses me is that the noise is the typical wheel bearing noise, but while driving and loading of the wheel bearings the noise does not change as it typically would while swerving side to side to load and unload the bearing. Is this problem typical of Ion 2's? I am not a throw parts at it till its fixed type of person. I plan on doing a full inspection again, I just fear that it may be differential related, I have heard that the transmissions are weak. Any insite and direction would be greatly appreciated. Thank you for your time!

Yes I have an Ion 2. I am positive the noise is coming from the front, I had the front end supported by jack stands and spun the front wheels to approx 20 mph, the noise was present then. I already replaced the driver side wheel bearing but the noise doesnt sound any different. I am hesistant to replace the passenger wheel bearing, they are a little expensive. Thank you for your reply.

Here's how I check wheel bearing with the front wheels off the ground and spinning put your hand on the coil spring if the bearing is bad you will be able to feel the roughness in the bearing thru the spring. Compare the left side to the right side so you can feel what a good one feel's like.

Thank you I will try that and get back to you. Is there any known prob with the CVT Transmission? Is it possible that there could be a bearing problem in the transmission?

The cvt or vti transmission was only used in the 4cyl vue and the ion quad coupe not the sedan ion. They only used that transmission in 2003-2004 and in 2005 stopped using it it the ion so your ion shouldn't have that transmission. To answer your question yes they had a lot of problem's with that transmission but in the ion car not that much. In the vue a lot problem's I rebuilt a lot of those transmission's in the vue but only a few in the ion's. To prove to your self you don't have one of those piece's of junk transmission's in your car take a look at the transmission underneath your car and you should see a normal transmission pan with a lot of bolt's holding it on. Is that what you see?Because the cvt/vti transmission's don't have a pan at all.

I also have the same problem. I checked wheel bearings but there's no problem. The noise came from the transaxle housing.
Did you figure out the problem?

I did figure it out. I ended up replacing both front wheel bearings and that took care of the noise. I also did a set of front brakes for good measure, while in there I noticed the back side of the rotors were unevenly worn and very rusty. I hope this helps.
