Last night coming back from Charlotte there was a heavy downpour, which doesn't bother the R one bit. Get almost home (about 45 mile drive) and this squeal starts from (seemingly) the right-rear direction from the drvier's seat. It linearly gets louder until even in the heavy rain/radio/AC, it's the loudest thing around. I quickly hit the hazards, slow down to about 15mph and limp 100 meters into the gas station. The loudness of the squeal is proportionate to speed of the vehicle. Inspecting the brakes everything looked fine. The pads are secure, caliper looks normal, no visible rotor damage on the outside. Waited about 45 minutes and drive home under hazards, slowly 15-25mph, and it did not squeal again, though it was still raining.<p>It's 60 miles back to University Volvo, I don't really know what to do here. The swedespeed discussions on this focus on the center resonator rubbing against the drive shaft?? I have an Evolve Sport Exhaust so don't know if I should still have this resonator, or not. Wouldn't the squeal sound like its coming from directly below me the resonator was at fault?<p>Help anyone? I need to know what to inspect before I drive again, even to the shop.

Re: Rain Squeal revisited (vLGrok)

I had the same problem and it was adjusted several times and no luck. Next time there was rain..... there was the squeel....<p>I did get the straight pipe and have not had the problem since. Actually, this makes the cab of the car quieter and does not make a noticeable difference on the outside of the car, although it may be a smidgen louder but mostly just more aggresive.

Re: Rain Squeal revisited (R_Rated)

I don't know if the Evolve exhaust has a center resonator or not.<br>Are you still running that strap?

NOt sure if there's a resonator in the Evolve system, but that's about where the noise from the normal squeal comes from. <p>And it's not a squeal, it's more of a singing noise, kind of like when you rub your finger on the top of a glass, but about 1,000 times louder.

Re: Rain Squeal revisited (needsdecaf)

I don't have a lift, so these pictures might not be that great of an angle. Is this the strap?<p><IMG SRC="http://www.valhallalegends.com/images/volvo/20060624-01.jpg" BORDER="0"><p>As for the mess on the pipe here, I can only guess a plastic bag got stuck on and melted.<p><IMG SRC="http://www.valhallalegends.com/images/volvo/20060624-02.jpg" BORDER="0"><br><IMG SRC="http://www.valhallalegends.com/images/volvo/20060624-03.jpg" BORDER="0"><br>

Re: Rain Squeal revisited (geoguy)

OK the strap will be removed. Back to the squeal, this section that has the melted plastic on it needs to be replaced by straight pipe to get rid of the squealing?

Yup. On the stock setup, the center resonator (which looks like the thing with the plastic on it) is what rubs the driveshaft. More specificaly, the crimp on the end plate of the resonator is what rubs. <p>When I took mine off, the end of the resonator had a half moon dented in it.

Is this dangerous to the driveshaft? Rubbing at high speed seems like a recipie for slowly eroding the driveshaft metal, weakening it.

Let us know if it goes away if this rain ever lets up.
