Hi guys had a ? about my 93 when I come to a stop at a light and then go to take off, the front driver side lifts up and makes a thud sound I'm not really sure what to make of it, I replaced the front shocks thinking this would help because they need too be done (floats on the freeway) I was thinking motor mount but when in neutral I rev the engine and no thud, could it be a transmission mount? She has the 318 with flow master exhaust and k and n intake any suggestions or advice is appreciated thanks

 

I would jack that side up and see if there's anything that's disconnected. If you press down on the hood that might help you narrow it down too.

Did it thud before you changed the fronts?

 

thats from the torque. it means you dont have enough power...lol jk. sounds like a trans mount or engine mount like ya said or you could have something loose in the front end.

 

Does the thump sound happen when you go around a corner because it sounds to me like a roll bar end.

To properly check the motor mount without looking at it, put the truck in drive with your foot on the brake and try to do a quick brake stand and release. Have someone watch to see how much the motor moves when you do this. Even have him or her watch the motor mount to see if it moves too much. I had a broken motor mount on my 3.9 and it did the exact same thing. There's a safety catch in there to keep the motor from jumping out that clunks pretty loud when it hits.
