Any clue? I have a 03 outback llbean. It has a vibration under load, and at
highway speeds. The tires were borderline, so I replaced all 4 assuming it would help. No such luck.
Anybody?

Vibration during acceleration which goes away instantly when you let off on the throttle can be traced to a bad DOJ on one axle. Check the inner boots on both axles; if one is torn, that's the bad one.

No ripped boots, and no clicking noise on tight turns (parking lot manuevers).
I held the wheels 1 at a time on the lift to try to isolate the problem. But, nothing made a difference.
Thanks for the response.

Clicking joints are the CVJs. But it was a thought.

Where do you feel it when you sit in the car? Back, butt, steering wheel, etc?

My old lumina got a "hitchup in it's getalong" in a similar way. When cruising along with low throttle and a steady speed it would hitch and buck a bit. It got worse and worse till I finally pulled the plugs (several hours work on that POS 3.4) and noticed that one of the tips of the plugs had burned off like a bastard. Replaced the plug and BAM! no problem!

an 03, is it still under warranty?

axle (what he said earlier) or ujoints in the rear driveshaft are my guess.
