Hey guys, thanks in advance for your advice. My '97 965 (166k) started howling like a police siren from the rear of the car at speed. Starts howling around 10 mph --- no howing in reverse. Doesn't matter if she's in gear or neutral.
I haven't gotten the car up on stands yet to check for slop/roughness in the wheel bearings. And the noise isn't squealy enough for brake pads.
What do you think? (from the faq): It probably is the carrier bearing Drive train howl is usually the carrier bearing, often a rear wheel bearing and if you have had a differential pinion seal replaced recently, incorrect pinion to ring gear preload.
Thanks! Chris in TX
