Wondering if anyone would like to help me tackle this question.
I have a well taken care of '95 Buick LeSabre w about 80,000. Bought it a couple years ago from a man who kept it in his garage. Most components on car are original.
Recently I was driving down a very steep driveway at about 3 MPH, and bottomed the car out and scraped the bottom. Not too bad, but enough to make me cringe. As I drove home at about 45 MPH, I noticed that every time the car would engage the gear, there would be a thump coming from under the hood. This was at about 1300 RPM. After looking under the hood and having a buddy rev the engine while in drive with the brakes pressed down, the engine doesn’t seem to move too much. Furthermore, the engine mount and Trans mount seem to be okay, and not broken. Rubber is solid.
Is the thumping sound perhaps due to ‘old’ mounts or could this be something else like the torque strut mount,etc? Also, will it be evident when one of these are damaged, or is it something you replace after a certain while like shocks, etc?
