I've seen several Tundras and Tacomas with rear diff failures at surprisingly low mileage. Toyota quality is rapidly becoming a distant memory. Their vehicles today are selling only because of past reputation alone. These days the diffs fail, the transmissions don't work right, the front diff vibrates, the 2.4L 2AZ-FE burns oil just outside of the warranty period, the 3.5L V6 has a nasty reputation for oil line failures and the latest version just doesn't seem to run very well and has had issues with stalling, the 5.7L V8 often has nasty piston slap and goes through water pumps/starters like they're going out of style, etc. It's very disappointing.
