last week on my way home,i lost my power steering assistance,managed to get it home ,good muscle building,had to work out the straightest way home.one of the pipes had blown off the rubber joint,got it back on ,the pumps making a noise,so think the pressure may of blew the hose off,where its not working properly,so new pump required,Lexus quoted me £851! gulp.does anyone on here know where to get a replacement,cars prob only worth £1500 on a good day,so spending a £1000 plus on it,does.t make sense really,any help or advice would be appreciated.not sure if i want to take chance on second hand as its quite a bit of a job to do twice.
