I brought my 2008 Outback H6 LL Bean in for a routing oil change the other day. (38k miles) I also had them check on a rattle I have at just about 40 mph...when slightly accelerating on a hill. My third Subaru... so I know the heat shield sound.
The tech told me that it was not this as the H6's do not have as many heat shield issues (is this true?)
They replaced my steering wheel pump under warranty and said that was the issue as it was loose and leaking. Free ..but did not fix it.
Should I go back and have them check the heat shields again? ONLY happens when already cruising along (not from a stop) around 35-40 mph.. have let off the gas a little and then lightly go to pick up speed. Rather loud ...rattle.
Don't you love trying to type out the explanation?!

My 2006 3.0R had heat shield issues. I fixed it by removing the existing nuts and bolts that hold them together and buying some stainless steel bolts and nuts and replacing the old ones. I think they were M4 or M5 size. It was a simple swap out.

Thanks...I will take a look and see if this is something the mechanically challenged can do!
I did notice another odd engine thing last night. The H6 is generally smooth when shifting...this time, I lightly pressed on the gas it the car seemed to vibrate for a second before finding its gear. I figure this is just the normal Subaru auto transmission feeling? My other 2001 had 'quirky' shifts too.
I always drive in Sport setting in my SI-Drive.

You may need to swap the computer, and possibly even the wiring harness, to get it right.

1.8 litre engine.
From dead start, a deep bass like rattle and thumping begins under the hood, under the engine, about midway between driver and passenger side. As I accelerate past 15mph or so, it goes away.
THought it was suspension, maybe driveshaft issues but my wrenches did lower ball joints, then did both cv 1/2 shafts (boots were torn and shot, grease all over).
When I turn left or right from a dead stop same problem, sometimes less sometimes worse, just like a straight line start.
If I put the tranny into 4WD (shifter button) there is no noise at all!!!!! WHich leads me away from suspension related issues?
Any thoughts? Drive train? Not suspension? Internal tranny splines where half shafts lock into?
Thanks in advance.

I am not overly familiar with the layout of the 1.8L's drivetrain, so I cannot pinpoint anything, but that sounds to me like an out-of-balance issue in a driveshaft. Perhaps a bushing through which a shaft passes is worn out? Basically, the slow rotational speed and initial torque is causing something to flex, which puts it out of balance and makes it vibrate/thump. As soon as the speed increases and/or the torque eases, it smooths out and is good to go until the next alignment of symptoms.
The part that makes me uncertain about this diagnosis is that it is in the area of the front differential. When I have experienced this in the past, it was in the drive shaft bushing for the rear differential.

Hmmmm, another one been around a while. When you did the half shafts, you did not mention whether they where replaced, repaired or what. I quit years ago doing my own halfshafts and now use a lifetime warranty units from either Rockauto.com or O'reillys. It helps with balance issues/ or bent shafts!
It is not uncommon for outer c/v bearings to sound off in turns when defective. You did mention torn boots.
Bottom line, I concur. Start with Cv shafts. I also recommend sparaying the boots with a silicone spary every oil change to make them last longer. Cheap and sure beats changing them.

Silicone spray? What sort... like what you would use to lubricate a squeaky hinge?
