fryboy3k Posted February 27, 2008 Posted February 27, 2008 I have a 98 Legacy GT and a few weekes ago a lite noise was coming from the front end when I turn left. Now the noise is much louder but it is not a clunk, or anything metal. It is more of a rubbing "whoomp" that is the best I can do with letters. This also is not constant and as you drive faster the "whoomp" also increases in frequency. You can here it as the car turns and when in park and the steering wheel is turned no such sound occurs. I have no idea what this is and I am wondering if anyone has had a similar problem. Thanks.
05GT Guru Posted February 27, 2008 Posted February 27, 2008 Could it be huge chunks of snow build up behind your tire and when you trun the tires rub against it
fryboy3k Posted February 27, 2008 Author Posted February 27, 2008 Since I am in the valley of California and it does not snow here. The sound occurs even with the slightest turn while driving. Thank you anyway.
Grimace Posted February 28, 2008 Posted February 28, 2008 Had this problem a week after i got new barkes and rotors. it was there for bout a week then suddenly went away. My dealer told me it was something that had to do with the rotors had to be broke in or soemthing like that. But neways it just went away itself.
andrew.anderson Posted February 28, 2008 Posted February 28, 2008 I say brakes or suspension. Don't know enough to narrow it down for you though. http://legacygt.com/forums/images/icons/icon9.gif
fryboy3k Posted February 28, 2008 Author Posted February 28, 2008 Thanks for all of the replies. I have been looking through the internet and have seen many problems with the wheel bearings for the subarus. My brakes are a few years old as well as the rotors, but I guess that could be it if they are warped. If it is the suspension though, I should be able to push down the hood and hear the same sound which I don't. Also if the brakes were grabbing the wheel hub and lug nuts should feel warm from the friction which it is not. This is why I posted this because nothing obvious has the same symptoms. It seems the only issue is the noise, but any guy knows that is more annoying than anything. Thanks again for all the ideas though.
ghostrider990 Posted February 28, 2008 Posted February 28, 2008 I just had a wheel bearing go bad on my 02 Maxima....very common for us. Have you hit any large potholes lately, or curbed your wheel? Easiest way to diagnose a bad wheel bearing: jack up the offending wheel off the ground, and grab the tire/wheel at 12 & 6, and give it a push-pull wiggle. If the wheel has "play" in it, and wobbles back and forth - you most definitely have a bad wheel bearing. If no play, your bearing is good - look elsewhere. Wheel bearings will elicit ALOT of different sounds and symptoms when they go, so this is really THE easiest way to diagnose a bad one. *Incidentally - get that diagnosed ASAP, as you risk damage to the HUB itself, which can TRIPLE the cost of replacing JUST the bearing. The bearing SITS in the hub....driving on a bad bearing for too long can ruin the hub as well -- ASK me how I know?! good luck. gr
ehsnils Posted February 28, 2008 Posted February 28, 2008 Wheel bearings may be relatively easy to check, lift the car and pull on the tire. It shall not be able to move at all. Also rotate the wheel by hand to get a feeling for it. Check the CV joints too. Pay attention to the right side inner joint since it is getting extra heat from the exhaust system and that means that the grease in the joint is suffering from more degradation. I have had one car where the inner joint had to be replaced, my parents one and on another car the inner driveshaft boot on the right side was the first to fail. Just for the sake of it - check that it isn't as simple as a failed driveshaft boot.
SuperCleanLGT Posted February 28, 2008 Posted February 28, 2008 I believe if it would be a WB it would be making a noise weather you were going straight or turning. Maybe some how you PS pully/pump got bumped and is not balanced properly. ?
fryboy3k Posted February 28, 2008 Author Posted February 28, 2008 The more I read all of this I think it could be the wheel bearing or CV joint. I thought the CV joint made a grind or clunk noise when you turned? Also the noise is there when driving straight it is just much lower volume. I am wondering how would I tell if the hub is damaged if the wheel bearing has been out too long? If the wheel bearing could damage the hub could it also damage the axle? Thanks again.
ehsnils Posted March 1, 2008 Posted March 1, 2008 For the level where you only get the noise there is no risk for the hub. The bearings are three parts, outer race, balls and inner race so you just replace the whole as a kit. However when things goes as bad as when the balls escape then you can get a lot more damage, not only to the hub, but also to brake discs and just about everything else. Just check that all wheel nuts are in place and tightened too! If it's on the right side they have a tendency to "self-tighten", but only to a certain degree. On the left side they are instead "self-loosening". This explains why older cars often had left-hand threads for the wheels on the left side. A CV joint can be noisy for a long time before the problem gets serious and you will probably change it long before that just to get rid of the noise. A wheel bearing however can cause warped discs and excessive wear on brake pads.
fryboy3k Posted March 13, 2008 Author Posted March 13, 2008 So i tried to move the wheel, with the car off the ground, and the wheel did not wiggle at all, so hard to say if the wheel bearing is actually bad. I looked at both and the same result. I also looked at the calibers, disks, and CV boot and nothing unusual. I also looked at the tire to see if there was any obvious wear that could represent a rubbing but nothing. I really do not want to take to a shop but it looks like my only option. Thanks again.
ehsnils Posted March 14, 2008 Posted March 14, 2008 In that case I think it's a CV joint that's worn. I suggest that you try to figure out which side it comes from. If it's the right side it may be the inner joint, because it gets more heat from the exhaust system which in turn makes the lubrication a little less effective.
blackfang Posted March 14, 2008 Posted March 14, 2008 Also look into the fact it could be transfer clutches too. They make a similiar sound and feel just like a bad CV axle.

fryboy3k Posted March 17, 2008 Author Posted March 17, 2008 To change a subaru CV joint do you have to change the whole half-axle? If anyone knows a place to buy just the CV it would be great to know. Thanks.
blackfang Posted March 17, 2008 Posted March 17, 2008 I would double check and make sure it is a CV joint(most likely will have to buy the entire axle). Transfer clutches make the same noise and shuddering. I hate to see you spend that kind of money only to find out you have another 1200 in repairs to do.

ehsnils Posted March 17, 2008 Posted March 17, 2008 Last time I did it I only had to change a single joint, but they may have changed the axle design. A few hours later and greased to the elbows I was finished and the noise was gone.
