Yeah, what is up with that? I know working trucks make heat and will break exhaust manifolds, but studs? I don't get that. [I know it's all about heat cycles but I don't recall that being a problem in the past... maybe it was and it was before the internet?]
I don't think that is a Tundra problem though...? at least I haven't heard of it (they have their own set of problems).
It is, guy I camp with tows a 30 foot 8000lbs trailer with his. Replaced a manifold and all the fasteners at 50,000ish miles.
Also did his cam bearings recently and he is at 68,000 now. His a 2014. Camps about as much as I do.
I see them at campsites and we talk they have the same problems everyone else does when you work them except for AFM failure.
I know they have updated the fasteners and manifolds on the newer GM to help prevent that problem.
Thanks.
Great. Another failure mode for me to obsess over!
Eh I wouldn't be worried. Not everyone has the problem and he runs his oil longer than I would towing that much.
