My mother had the wierdest thing happen yesterday. She was driving her '97 GP out of a parking lot and heard (and felt) a very loud, quick thumping coming from the back (from the trunk area). She described it as the sound of someone inside the trunk kicking toward the base of the windsheild as hard as they could. I was thinking it was what happened to our GP (the strut popped right up through the bracket on the wheel well and was smacking the bottom of a speaker) but she said that it doesn't happen just when hitting bumbs (though it'* always when moving).

Does anyone have any other ideas of what it could be? She'* taking it in to a mechanic ASAP, but I'd like to know if it'* something she shouldn't be driving with.

Edit: And before anyone says it, no, it'* not someone in the trunk. She did check.

Well you're no fun! JK

I have no real idea, but it sounds as if it were related to the suspension or brakes. Keep us informed.

I will...I told her to pull up the trunk liner and look, but she is not at all mechnically inclined so it will probably yield nothing. I wish I could go check myself, but I don't have the car today so I'm stuck at home.

who has your car! I wouldn't stand for that!

I hope it was Mr. Hailey (lol sorry Rob, couldn't resist) cuz if it wasn't she can unload a clip real quick

sounds like a broken strut mount to me too. :(

Is this typically a GP problem? Never heard of it happening to Bonnevilles :?

Before we go straight to the mechanical, does she listen to the radio when driving? I've heard of a similar situation where a loose speaker wire was dis/connecting to the speaker and causing that thumping noise you get when you turn on a guitar amp. In a car, it sounds lik a muffled thump.

Sounds like a strut mount is broken,the torsion bar has broke loose from it'* mount,or the trailing arm is somehow loose/bent/broke :?: ,...she should drive as few miles as possible before getting it diagnosed...........

Thank you all so much for your responses...I will be calling her as soon as she gets home from work to make sure she gets into a garage ASAP.

It could be a speaker thing...she definately listens to music, and loud sometimes (my mother can be so cool...she loves Godsmack, Linkin Park, and listening to WAAF ).

It'* so nice having you all around to ask this stuff. You're the best!
