New to me 2000 LC with 287k miles, the power steering whine has me stumped. Reading on the forums I’ve already cleaned out the reservoir twice, replaced the pump with an oem toyota ps pump and the hoses. Bleeding the system I’ve turned the wheels with the truck jacked up, not running, then jacked up running, and finally on the ground. I’ve also checked the rack for leaks. The fluid still is aerated even after using additives, I’m stumped! Any help would be greatly appreciated, also I’m around the Raleigh NC area if there are any LC gurus nearby.
