Crazy issue here which I can't seem to put my finger on. When my '01 PSD sits in the cold weather (let's say below 25 F) for more than about 2 hours, I hear this terrible noise coming from the rear end or brakes/wheels when I put it in reverse. The noise sounds like it would if your tires were frozen in water then broken free. And it only happens when it's cold, and only in reverse. If I go straight to drive for a few feet, then into reverse, it still does it. When it sits in the garage over night (not heated, but it's usually a little warmer than outside) and back out it doesn't do it. If it only sits for a short while it doesn't do it either. At first I thought that it was because of snow/slush getting on the calipers and rotors going down the road, then freezing when it sits. But it still does it even on dry roads. Anyone every had this issue, or have any suggestions? Thanks!

Matt,
How many miles on your X?
When you put it into reverse and hear this noise, does it happen with the brakes applied, without the brakes applied, or both? I'm trying to pinpoint if it's a brake/caliper issue or a differential/axle issue.
What condition are your rear rotors and pads in?

108K miles on it. New pads installed at about 95K. Rotors look fine. Since I have to press on the brake pedal to shift from park to reverse, I'd have to say that it's WITH brakes applied. I could try to press the brake just enough to shift, then release before it actually engages in gear. Might help rule out a caliper/rotor issue, eh? Too bad it's 36 degrees here in Michigan, probably won't know unitl Monday now unless I leave it outside for the night.! |

Yeah, if you can release the brake and see if it makes the noise, it'll help with troubleshooting.
Also, do you engage your parking brake at all? Have you tried engaging it and releasing it since this problem crept up?
Just trying to get a feel for all of the variables!

Actually, I've never used the parking brake. I'll try to exercise it a few times to see if it feels funny. Wait for some more cold weather and I'll let you know. Thanks!  |
