Hi guys,new to this site and I'm after some help with a problem with my 97 l/cruiser,I recently changed the two metal pipes on the power steering(non toyota parts a diy fix) since doing this the steering is ok at driving speeds but really heavy when doing manoeuvres like parking etc,lve bled the system several times by turning wheel lock to lock,wheels off the ground but no change,ive even disconnected the low pressure pipe from the resovoir and bled a couple of ltrs of fluid thru the system into a container and its still the same,anyone got an idea wot the problem could be(everything worked ok till I changed the pipes)
