subestyle18 Posted November 30, 2004 Share Posted November 30, 2004 On my 4wd 83 wagon I get a wherring noise, which sounds like bad tires but changed the tires and the noise is the same. The faster the noise the louder the noise is. I thought it was the front left wheel baring and changed that but its still their. When i turn to the left and the weight transfers to the right the noise goes away. Others tell me that i doent sound like a wheel baring. Now im trying to figure what else could make this whering sound. Any ideas would be great.Thanks David Quote Link to comment Share on other sites More sharing options...
idosubaru Posted December 1, 2004 Share Posted December 1, 2004 can you determine left/right or front/rear? any vibrations? how are your brake pads? how are your cv axles? (age, boots torn...etc) does it do it whether the car is in gear or not? does it all the time? any speed? Quote Link to comment Share on other sites More sharing options...
subestyle18 Posted December 1, 2004 Author Share Posted December 1, 2004 The sound stays constant with speed, it has nothing to with engine RPM's, whether its in gear or not. It doesnt sound like a clicking CV joint and none of boots are riped. THe front pads look ok and the the noise doesnt change when you hit the brakes. This is my first 4wd so i dont know what the transfercase or rear diff sound like if or when they go bad. Im going to start taking things a part and looking around so any ideas would be very helpful.

Ross Posted December 1, 2004 Share Posted December 1, 2004 Jack up all wheels & check wheel bearings for excessive play or roughness. Just because the noise goes away when turning right doesn't mean the left beairng is at fault. The right bearing will be under less total load, but the load will change direction, which could make the noise quieter or louder. Quote Link to comment Share on other sites More sharing options...
ShawnW Posted December 1, 2004 Share Posted December 1, 2004 Did you replace the inner and outer wheel bearings? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted December 1, 2004 Share Posted December 1, 2004 if you can't pinpoint a side, it may be differential noise. (front or rear) try checking the differential fluids or changing them for good measure. use a quality synthetic gear lubricant within the specifications of your diff. your tires that you replaced, were they old, worn in bad shape? were they a matching set of tires or all different? check wheel bearings for play/noise/etc. jack up car and turn wheels by hand. remove wheels and turn the rotors/hub by hand and listen for noise or feel for roughness. pay attention to rotors, brakes pads, wheel bearing and cv noise. grab your cv axles and make sure they feel solid. sounds to me like it has to be a moving part.

subestyle18 Posted December 2, 2004 Author Share Posted December 2, 2004 I've pulled the wheel hub axel from the right side and the outer wheel baring has a slight grinding feeling when i turn it by hand. So i am guessing that it needs to be pulled and repacked/replaced. Thanks for the help David Quote Link to comment Share on other sites More sharing options...
Ross Posted December 2, 2004 Share Posted December 2, 2004 Don't bother repacking the old ones. Bearings are so cheap (especially the front deep groove balls) its simply not worth it. These subies can go through front wheel bearings faster than most other cars. While the bearings are out, check for wear on the spacer between the two bearings. This wears when a bearing gets worn out and heats up more than usual. THe resulting expansion of the bearing causes it to lock itself to the knuckle (The beairng should usualy be able to 'creep' around the knuckle, to give uniform wear over the outer race), while at the same time loosening around the axle. Because of this, and the increassed rolling resistance of the worn bearing, one bearing can spin on the axle, while the other does not. this results in wear on the spacer. This is by no means a common occurence, but it is worth checking anyway, as significant wear on the spacer will cause the bearings to wear out very prematurely. You can tell if the spacer is worn by looking at the faces, there should not be 'rings' worn into it. Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted December 2, 2004 Share Posted December 2, 2004 it may be a rear axle sounds like grinding all the time when moving if you have to clutch to shift into 4x and the noise disappears, it's an axle in the rear, btdt Quote Link to comment Share on other sites More sharing options...
