need help please help

vibration/binding noise

I Have A 2000 Jeep Cherokee. It Has The Extreme Duty 5.5 Kit On It, Then I Added Two Inch Blocks Plus A 6 Inch Leaf Pack In The Rear, The Front Got The Acos Adjustable Spacer. Everythign Was Fine Untill I Put The Long Arm Upgrade On It. Now Evertime I Drive I Get A Binding Noise Of Vibration Noise From The Rear, I Have A Sye Kit And Drivshaft Already. it sounds lite my cv is hitting or grinding but there are no marks visable

shims...
search this place to find the right size for your lift but you gotta shim your rear axle to make your pinion angle match your drive shaft angle.. or close enought to make it not bind up like that... i have a 4.5in lift and 6 degree shims are needed for it... math might tell you that you need 8 degree maybe or somthing like that.
search for it they are called degree shims or axle shims

that's about all i can think of to tell ya. hope it helps.

How's your rear pinion angle?

remove the blocks. Axle wrap is probably binding the drive shaft. then check the pinion yoke angle.

I am interested in buying your drop brackets and possibly the control arms if they are adjustable and you still have them laying around.
