Brought another sport over the week thinking of keeping it the issue is the diff isnt working well i tryed to spin the back and the revs just bounce up and the car doest move as much in 1st once its rolling it drive normal just no diff action in 1st ive had a look under the car the diff looks all wet and its leaking the cars done 87k would a simple oil change fix the problem or am i looking at a new diff unless theirs a place were i can get it rebult ?

There's nothing wrong with the diff. The clutch is shot.
