Default Grinding Sound when slowing down

Hey I notice when i am driving and i go like 50mph and then i let off the gas and i hear this weird sound coming from the rear sounds like a grinding sound i guess i would say. Is this normal if not what could be causing this?

It wasn't making this sound before. Started making it when i installed the flip kit.

I notice my rear is axle is pushed up and the drive shaft and the rear axle are not straight anymore because the rear is pushed up from the flip kit..

That's the problem. You need to reset the piņon angle or it will eat u joints.

How do you reset the pinion angle?
Is that hard to do?

You will need something to cut the spring perches loose. A welder to weld them into the new position. You will need a piņon angle finder.

All you need is some degree shims, get the stock degrees of your rear axle then find out what it is at now, get the proper shim place it between the spring and the axle tube. All you need is a degree measure and rachet and socket to take the ubolts off

I just went to look at my drive shaft and it doesnt even look like its bent much though. So could this be what the problem is?

Pictures would be good because i am still confused on how to do this.
I also have the stock shocks on my rear. So i am not sure if they are too long and could be causing the problem.

Oh, So basically i need to buy a pair of this Pinion And those go under my leaf spring plate? So all i got to do is unbolt the 4 screws on the bracket and put this above the plate and rebolt the plate down?

Will not doing this cause damage to something or will it just keep the vibration and not hurt anything?

I think i figure out why i am getting the grinding sound.

I did not drill a hole in my spring plate. I notice that the leaf spring bolt is not going in the middle of my spring plate.The leaf spring bolt is suppose to go in the middle of my spring plate? Correct?
