I have a 99 legacy outback. I had it in the shop for a torn CV boot and was told it was cheaper to change the axle. The moment I drove from the shop, at the first stop sign the car began to shake violently. Only when the car is stopped and in drive or reverse, when I put it in neutral it purrs like a kitten! Help!! It is sometimes worse than other times, but it is always there to some degree.

 

I took it back to the shop…and to him, it seemed a motor mount but after checking found nothing. Nothing shows up on the computer either.

Thank You

Hm, that's kind of weird and seems more than a coincidence. Related to the new half shaft the only thing I can think is it is somehow skipping, not sure if that could happen in the DOJ or whatever joints thus causing the vibration when stopped and in gear; obviously there's torque on the thing when stopped. Or maybe they screwed up the output from the differential somehow. I would think they would have test drove the thing after replacing the half shaft. Sometimes the aftermarket half shafts aren't the greatest.

Sounds like you may have a wrong sized or poorly rebuilt half-shaft. Use the search functions and search for "shaft shake" or similar key words.

 

Here's one link that popped up for me:

This has been known to happen. Was it an OEM (remanufactured) shaft?

 

It's one of those Subaru quirks. My dealer changed out one under warranty when I complained. The second one was not quite as good as the original, but much better. When the other front half shaft was changed, I again gained a bit more shake, but (mostly) acceptable.

 

There have been a few threads on this recently.

An older thread, but you might want to read it anyway.
