Definitely no mechanic me Poopsie Mate but if it’s “whirring” when driven I believe the thrust bearing should be discounted?
Any chance you’ve given the LS3 a really good test run and possibly hearing our weakest link (transfer case gears) whining a wee bit? Only mention it as in a previous life my little 150rwkw 350 NA Fj40 Landcrab destroyed inferior OEM cases with whining Toyoda telltales firstly
