Howdy all,

I was looking through All Data and came across a Service Bulletin that described exactly the vibration I'm experiencing. It only seems to occur in Drive when stopped. The vibration came about when I upgraded from the local muffler shop's POS to the Volvo muffler. The SB references a brace that runs from the end plate on the AW-71 to the exhaust pipe from the manifold. A clamp on the end of the brace finishes up the fix.

I'm wondering whether anyone has done this fix and, if so, whether they used the new recommended AW endpiece or if the stock part will do. I've already ordered the brace and clamp, it would just set me back a couple of weeks (and $25 more) waiting for the new part to come if the stock part doesn't work.

Thanks in advance for any and all observations,

Jack
