How much is your lift?
My issue sounds the same as yours except… mine started after I swapped my old OEM to a new OEM axle. I replaced the needle bearing with an aftermarket bushing but still have vibration in 4wd while accelerating. So I took it to Toyota, they determined the axle was bad, swapped it to a new OEM but it still vibrated… so they said my lift was too high and I need to lower it lol. It’s only 3”… already have a diff drop but my shocks are ridic stiff so maybe that’s a factor. Not sure, but I’ve been pullin my hair out over it for the last 2 months with no luck.
