Well, way back in 2013 I had my front differential replaced on my 2011 SR5 under warranty because front end noise that was diagnosed as left front needle bearing failure.
I had to take 4R back three times before dealer and Toyota found the issue, back then there was no TSB yet. When dealer took apart differential they found needle bearing was pretty much destroyed and axle was riding on the diff housing and fluid was seeping out of seal.
Fast forward, my 2020 TRD ORP had the same noise from day one, I took in for service and was told this is normal, noise went away when I engaged 4WD.
Couple weeks ago I traded that 2020 in for a 2024 and so far this one is completely silent of any noise in or out of 4WD. I'm just curious what Toyota might have done to fix this issue or am I just lucky for now. I will know for sure as miles increase.
