Please help rear end noise
Hey im new to this site please help.
I have a 2000 durango 4x4 and when i come to a stop and turn either left or right a popping noise and a vibration comes from my rear wheel. Or rear end. Not sure. Does anyone know what this may be?

Haha that's alright. The rear-end, or rear differential, is what's connected to the driveshaft. It has gears inside that allow the driveshaft to turn the tires; as well as it has gear oil inside to provide proper lubrication
An open differential means that power is directed to only one wheel which makes turning much easier because the wheels can then easily spin at different speeds.
A limited-slip differential can provide a majority of power to one wheel and then a proportion to the other wheel. When making a turn the wheels may not be able to spin at different speeds due to the power being delivered to both of them, causing some chatter or vibration.
The gear oil in the limited-slip needs an extra friction modifier to be added to help with the clutches inside to work properly
To answer the original question: yes, it's pretty normal if you have a limited-slip

not quite, as long as both wheels have traction both wheels are receiving power, however if one wheel begins to slip that is when all the power goes to one wheel or the other.
a Limited slip can divide the torque, and multiply it across to the wheel which still has traction, usually by a factor of 5, although if one tire completely looses traction it will STILL SPIN ONE WHEEL ONLY
however the rear diff as a limited slip is still a very real possibility since my dads truck exhibits similar symptoms when it is due for a fluid change.

Best thing to do, is remove the inspection cover and inspect for any broken clips from the clutch plates for the LSD. Also look at the sprider gears too, And check for any debris as well.
