I've got some pretty serious driveline decel noise so I periodically search the internet for something new. I came across a Subaru thread where SOA recommended decreasing pressure in the rear tires to achieve more uniformity in the tire diameter front to rear. So, I went out and pulled some pressure out of the rear tires. Now running 36psi front, 30psi rear. I have to say, the grumble is MUCH IMPROVED. I still have some nasty gear rattle/scrape coming from the front but the loud growel from the rear diff is now significantly diminished. So, if you've got loud driveline growl under decel, try taking some pressure out of the back tires and report the results. Once we have more data we can discuss why this might be a valid/good/bad solution.
