I have an 03 Tundra 4x4. 200k miles. In the last year I replaced the upper and lower ball joints on both sides.
Six months ago I got rear ended and the frame broke due to rust. Turns out it was covered by a recall and Toyota actually replaced the frame. It took them five months.
So I just got my truck back two weeks ago. It’s been driving fine. No (foreshadowing) symptoms of a bad ball joint. Not shocking cause there shouldn’t be.
Then, yesterday, the driver front wheel goes perpendicular. Lower ball joint sheared off.
Dealer says they told me on page 40something (of a literally 1” thick) work order that it needed to be replaced. I asked a few things including why would it when it wasn’t old- but they had no answer to that.
Question a: could they have damaged it?
Question b: is a sheared off ball joint ever a symptom of something else? (Besides bad maintenance, thanks ;). )
Question c: what could happen in the process of changing a frame that would take a lower ball joint from a year old fail?
