2020 Toyota Tundra — metallic rattle for a few seconds after cold start — second opinion before I spend money

This is usually cheaper to test than to guess. Two 2020 Toyota Tundras can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. No need to make it theatrical. I already checked the easy fluid levels.

Start with the test that can prove you wrong. Loaded-suspension checks on the 2020 Toyota Tundra catch play that a wheels-hanging inspection misses. Save the big job until that test fails. When does it actually happen? Video is ugly but it shows the hesitation.

This is usually cheaper to test than to guess. Swap the cheap/easy piece first on the 2020 Toyota Tundra and see if the fault moves. Save the big job until that test fails. Learned this the expensive way on a previous car. That's coming from doing this as an owner, not a shop. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2020 Toyota Tundra and see if the fault moves. If the cheap test changes it, stop and reassess. Was this after sitting overnight? Might be overthinking it, but I'd rather overthink than overspend.
