Rear end ticking noise during boost launch?

[TYZ06]

SyTy,

I had a questions for the community regarding a ticking/cluncking noise that is coming from the rear end "only during boost launches". Since I have owned the truck it has done this (last 5 miles, 6 months). Last weekend I installed a new Perfect Launch rearend cover and replaced the rear end fluid as well as transferer case and tranny fluid + Lubetech (with B&M Trans Pan).

All the fluids looked good as they were all changed about 15k miles ago with Amsol products.

The truck is lowered 2inches with 18 vet wheels as well as belltech rear sway bar. Let me know what you guys think. I was thinking that the diff may be slipping or going bad?

being lowered, i would start with checking the pinion angle and also the rear u-joint.

Does it "squat" down much when launching? Mine was acting in a similar fashion but new generic shocks fixed this issue. Mine is Lowered a bit as well.

Could the noise be clicking from a worn transfer case chain jumping teeth?

what kind of brakes on the rear ? drum or disc ? If disc maybe pads are slapping around in bridge and causing noise . Or loose suspension components ??
