chiguy Posted September 12, 2006 Share Posted September 12, 2006 Okay, I'm sorry to post what I'm sure I could find by searching, but I've tried and I don't have enough specific terms to make a search productive... Anyway, my 95 Legacy AWD wagon just sat for a week while I was on vacation. Yesterday, when I started pulling out of my driveway, I noticed a noise in the rear end. It may have been more on the passenger side or in the center, hard to tell. It wasn't a grinding noise, just a rrr'ing type noise and it wasn't very loud. It varied with each rotation of the wheels, so it was definitely related to when the wheels turned. Not having much of a choice, I drove the car gently and as I suspected, the noise went away after a few miles. I'm guessing there is something that dried out/drained over the course of sitting for a week. I don't know a lot about the rear drive train and wasn't sure if this meant the rear differential needed lubing/fluid, etc. or what. I was hoping maybe some here could give me some ideas of whether I had a maintenance issue here I should be addressing. I'm hoping that the noise appearing after sitting a while and then going away after a few miles gives some clues that people more knowledgeable than me could figure out. Thanks!

cookie Posted September 12, 2006 Share Posted September 12, 2006 A couple of things come to mind. Tires flat spot after sitting and sometimes your rotors rust a bit and clear off with running. I'm sure somebody else has some ideas too. If it cleared up i would not worry until it gets worse. Link to comment Share on other sites More sharing options...
J A Blazer Posted September 12, 2006 Share Posted September 12, 2006 My guess is that since you are in Maryland, and it rained a lot last week, rust accumulated on the rotor which can take some time to disappear. Unless the sound reappears I wouldn't worry about it. Link to comment Share on other sites More sharing options...
cannonball Posted September 12, 2006 Share Posted September 12, 2006 My (un)educated guess is that a wheel bearing is in the initial stages of failure. Esp. since it changes while cornering. At least that's what happened to me in my 00 OBW. I swore it had to be the rear diff, and I was prepared for the worse. The shop replaced the bearing and I'm riding quietly now. It's possible that the grease in the bearing settles after sitting and then relubes after driving a little bit. It could be the seal itself is damaged and making the noise.

Sube dude Posted September 12, 2006 Share Posted September 12, 2006 I've been waiting for someone to post this problem. My '95 does the same thing as noted in the original thread. It seems to be nosiest when you first drive away but the noise comes back when you back off the thottle. I suspected something in the rear AWD system (which I don't much about as my GL was FWD and my Loyale has the mechanical/selectable AWD system but the previous post here has me thinking it might be in a bearing of some sort back there. I had a shop check out the driveline on a hoist and road test it but they didn't come up with the cause. There's 275k km. (~170k mi.) on it, mostly highway driving. I suspect all the bearings are original. Any feedback would be appreciated. Cheers. Link to comment Share on other sites More sharing options...
