Hi all. Have noticed power steering fluid leaking onto the ground from the passenger rubber boot. Not much, maybe a drop every two days. Haven’t lost a noticeable amount of fluid, not even enough to top up the reservoir. I’m considering replacing the boot but that will only mask the leak. Is it possible to replace the seal, which I’m assuming is failing here? Or can only the whole rack be replaced. Drivers side appears fine. Have noticed there’s a power steering whine, not sure if it’s possibly bringing in air through this leak too? Have also noticed near the rear diff at the end of the drive shaft I believe, it appears there’s something leaking but must only be at high revs, nothing noticed on the ground, only picked up on it when I was under the car. Looks like it’s leaking out when spinning?
