Crawl under the truck and give your drive shaft a twist back and forth to check for U joint slop. Then check for slop in the trans tail shaft by pushing the driveshaft toward the front and back of the truck. Visually inspect trans mount, pinion snubber, leaf springs, and shackles, and just for the heck of it check motor mounts. You can have a buddy watch the engine while you put it in drive and reverse while having the brake on give it a little gas and see if the engine moves. If still nothing pops out at you look at the underbody by the differential to see if it's been winding up as you say. Look for frame cracks etc. If none of that is bad its internal.
I did check these things and nothing stands out.
Not sure if now I should be looking at trans or diff.
Maybe a better desc would help but not sure what to say.
Doesn't seem to do it in reverse, if I ease into the gas than I can sometimes get it to not do it but I've really gotta be easing.
Ok so I give it gas, the truck move instantly but there is a very perceptable thud coming from somewhere.
Going down the road and letting off the gas I.E. coasting and then giving it gas and I don't get any thud.
Seems to only be from dead stop as far as I am able to tell.
Truck has 103 and I don't know much history of it except it's never been in the salt.
Just a light coat of surface rust on frame
