My '94 STS has a rattle that has started about a month ago, I thought it might be the front motor mount, I looked at it,(the one at the front center with the brace that goes up to the head), and it is questionable, the brace is about .25" from touching the bottom part of the mount.
But this rattle is not present when parked, and the engine running, I can race the engine, torque it under load, and idling with no rattle.
when going down the road the rattle is there when hitting bumps, or cruising down the highway.
Could it be the catalytic converter? I banged on it with my hand and it seem to have a rattle to it that is similar to the rattle I'm looking for.
just replaced my Links...did the job....Rock Auto sells after market ones by MOOG...they have grease nipples and should last longer...you can check em by wiggleing them, there should be no play..also check the sway bar bussings.
