Rear u joint not tight enough enough or wore out?[/QUO

I DON'T THINK THATS IT CAUSE NONE OF THIS WAS HAPPENING BEFORE THE GEARS WENT IN. I CALLED THE SHOP THAT DID THEM AND THEY SAID THAT THINGS LIKE THAT HAPPEN WHEN YOU GO TO A STEEPER GEAR BECAUSE EVERYTHING IS MOVING FASTER NOW AND ALL THE MOVING PARTS HAVE TO CATCH UP WITH EACH OTHER WHICH DOESN'T MAKE A LOT OF SENSE TO ME. I GUESS I GOTTA TAKE IT UP THERE AND HAVE THEM REDO IT. THANKS FOR THE HELP GUYS.

does this thud happen when you let off the gas without the brake or when you first apply the brakes.

when exactly does the thud happen, info i am looking for is.

1. is there any thunk when you accelerate

2. when you slow down what MPH does the noise happen at? is it when the car comes to a halt, when brakes are first hit or what.

before we condem the rear end itself atleast give us a decent description of the noise. so far I see no reason to suspect the ring and pinion setup.
