i need some help with my car. i think ive chipped a gear in my rear end. when i down shift too second gear and drop the clutch to take off i feels like my rear end is trying to lock up. and i hear a loud pop and crack all in on but after that its fine. and it doesnt do it when i let the cluch out slowly. its hen im going about 45 and put it into second and dump the clutch

 

You really don't need any help, you need to go out and pull the cover and look.

 

ok thanks i just wanted to see what all yall thought before i did that. oh does this rear end have rtv sealent or a gasget?

 

It's so much more acurate for you to look than for us to guess.
They generally come from the factory with 2 gaskets. I usually clean everything up really good and use a thin film of silicone and one gasket. Many use just a thick bead of silicone but I don't because of the clean up for the next time.
