My Question : I’ve got a 04 Tahoe 4wd model & love it ! My steering is now sloppier than I like . Soo can a 07’- & later power steering rack be installed (up graded ) on my 04 ‘ 4wd model ? I do know what I’m doing around cars ( 40 yr professional mechanic) & have always wondered about the crossover /upgrade . I can’t be the only one thinking
