Creaking Rear Passenger Leafs

Hey All

Need some input here as I’m at my wits end. I’ve had the Ironman Nitrogas Suspenion kit on my 19 Tacoma for a few months. Like many before me I went too aggressive on the load rating for my leaf pack. Per the Ironman rep I removed the proper leafs to reduce the rake and stiffness. Now I’ve got this incredibly obnoxious creak not squeak on the rear passenger suspension that presents itself when I take a hard right turn or pull into my driveway from the right side. I’ve applied lubricant between the leafs. I’ve checked torque specs everywhere. I’ve applied lithium grease spray to the bushings. Could it be a twisted bushing? Maybe the shop torqued everything in the air and twisted them? Anyhow, anybody else had this issue and fixed it? Thanks for any input

sound I’m describing is similar to this
