I have been reading the replies to your question and I keep wondering why my posted question [Unusual Sound at High Speed in 2004 Subaru Outback Wagon] has not been addressed beings it is so similar to your problem. I see that someone replied that it may be your heatshield. Well, I would be curious beings my dealer thought the same thing and after adjusting and replacing a broken exhaust bracket, the vehicle still continues to rattle between the speed of 70-75 upon acceleration. My husband thinks it could be the speedometer cable getting stuck at the 70-75 point. The dealer has not seemed to excited about this theory. Although I love Subaru's as this is my second one, I am beginning not to love the dealership mechanics and/or Subaru of America. Any replies are appreciated. Thank you.

I had a loose heat shield on my 2000 OB about 3 years ago, and now it's loose again (or another one). Both times it manifested itself by a metallic buzzing at about 2800 rpm (in my case). So I hear it in every gear at the same engine speed, but not at the same road speed. If your's is loose and rattling at 70-75 mph, I think you would also hear it at the equivalent engine rpm in the other gears.
Of course 75 mph is 120 kph in Canada and illegal anywhere near where I live

Thank you for your reply. I actually spoke with the dealer this morning and they are now suspecting my exhaust and have ordered a new one. At this point they have checked and adjusted my heatshield and replaced a broken bracket on my exhaust and are essentially picking at straws because the noise is so baffling.
Although our general posted speed limit in So. California is 65, if you are going any slower than 70, you run the risk of getting ran over. The CHP usually allow you those extra 5 mph. There are also other areas in So. Cal. with open highway that the posted speed is 70 mph.

Hahahah... I hear you! When I drove my 1969 Chevy pickup from Alaska down to Oregon, over to Pennsylvania, and back up in 1999 the only place I did not feel like I was poking along was Canada! I pretty much set it at 65 and just let it purr. Everything passed me in Montana and Wyoming!
#6217 of 8657 low to mid rpm pinging
Jul 07, 2006 (4:34 am)
Hello all! I have a 2000 outback wagon with 81k on it now. I think my engine is pinging when I go up a slight grade from 1 to 2k rpm. I use only top tier 87 octane gas, it's up to date on maintenance. I tried using midgrade, but it still pings. There are no warning lights on (CEL's). Would a scanner detect what is wrong even if no warning lights are illuminated? Thoughts? Thanks Eric

Iím assuming that you have a four cylinder so did it just start or has it been happening, but getting progressively more apparent. Some things to think about are did you change the brand of gas that you are using and also maybe itís time to change the plugs and get the timing checked out. I hope this helps one other thing it could be the summer blend of gas

No, it's probably been happening for a couple months now. One other thing, I recently changed the battery and by doing so rebooted the ecu. The way I understand it is the ecu will start with a rich a/f mixture then lean it out over a couple tanks of gas. Granted we had the a/c on so I couldn't listen very well, but I didn't hear any pinging the last 2 tanks. Only recently it came back. Could be the timing--I've long suspected the timing belt tensioner was going bad. I wouldn't think it would be the spark plugs or wires--they were changed 20k miles ago.

Eric, If you have no CEL a scanner will not show a fault code. But perhaps if you use a fancy one that can create a test drive event log for subsequent human analysis it may show something, if you have the skills to interpret the data correctly.
I too have a 2000 OB. The car is made to run on regular fuel and the ECU will adjust timing to compensate for conditions, so you should never hear pinging. All you are gaining from using premium fuel might be more or better cleaning additives, etc. If what you are hearing really is pinging then your ECU is unable to compensate for some condition it is experiencing.
I have no experience of the automatic OB, but it seems that perhaps you have a standard if you can go uphill at 1-2k rpm. I hate to appear critical, but I don't think I would drive on the flat at rpm as low as 1k, and certainly not uphill. If you do have an auto, perhaps the shift points are too low.
#6221 of 8657 Exhaust system noise
Jul 07, 2006 (5:16 pm)
My 2002 Outback has an exhaust system vibration around 1600 - 1800 rpm. It's pretty much only those rpms. I looked underneath the car, could find anything obviously loose. The heat shield seems to be ok. It's not that bad, just noticeable when the window is down. Is there any general fix for this? It seemed to develop over the last few months. I bought 4 new tires along with front brakes & rotors last week, the mechanic couldn't find anything loose while it was up on the lift.

Well I thought the same thing. I have a 2005 Sub Legacy GT Limited Wgn, and had the same issue at about 15,000 miles. I took it in to my dealership, and the first time they were unable to figure out what it was. The whining noise became so annoying that I avoided driving around with my windows down (which I enjoy). I took it back, and they replaced the wheel bearings. It was quiet for about 5K miles, but it's back and louder than ever. They may have improperly installed them or this may be a persistent problem for the car. I don't know, but I'm glad I got the xtended warranty so I can take it in every 5-10k miles to get this taken care of . Besides that and the nagging seatbelt chime, I love the car!
