Power Steering Fluid problems of the 2006 Toyota Tundra

Takata recall 2006 Toyota Tundra sr5 4x4. Purchased about a year ago. Power steering failed a couple months in while driving to work. Found fluid leaking I crawled underneath and founf the entire frme rusted and both anti roll bar links have separated from control arms. The bushings and nuts were missing and the powersteering link is from rotted boot on the pasenger side.

This started 1/7/2017 coming home from work back gravel road heater would not work noticed heat gauge went all the way up then came down to normal worked ok for a while did it again. Drive home approx. 10 miles did not get hot but temperature gauge registered hot slowly drove home put water in after cooled off. Had to leave at home till I made appointment to bring in. Did not bring to dealer which is 40 miles away drove 8 miles slowly to mechanic. He replaced radiator, filled with new coolant mileage 91003. Did not mess up until 2/27/2017 same road registered hot drove home shut off added water, had to sit for a few days till opening for appointment. He did not fix he checked out found 2 leaks one dealing with transmission and the other dealing with steering or ball joints. He is concerned because it ran out of fluid even thou I filled up ASAP. Never had a problem before. This is what he says possible head gasket leak near steering rack. And between engine and transmission possible front seal. Also I will be calling the dealership tomorrow in olathe, kansas.
