With some excellent help from the camryman.org forum, I found my problem. The low pressure fluid return line on the power steering pump was leaking very slowly. Easy fix; slide the pinch on clamp up the line 3/4" and add a regular hose clamp on the pump side, just medium tight. Problem solved, right? Not so fast, bubba.

Drain all the fluid from the reservoir, take it out of the vehicle and look in the bottom of it. There was a 2 or 3 mm layer of blackish 'crud' in mine. Use your solvent of choice (gas, alcohol, paint thinner, lacquer thinner, acetone, Berrymans, whatever- i used gas), and slosh it around and dump it several times until you can see the fine filter-mesh in the bottom of the reservoir. You want that crud circulating through your rack? I didnt think so. Once the tank is clean and dry, hook it back up, and put a half cup or so of fresh ATF in it. Disconnect the return line down on the chassis, and catch the fluid with your oil change drain pan. If you have jacked up the front on both sides so the wheels are clear of the ground (recommended), then just muscle the wheel back and forth from stop to stop, refilling as necessary from above, until you see nice clean red fluid. Hook everything back up, start the vehicle, check the fluid level, warm it up, running the steering wheel from stop to stop several times to bleed all the air out.

Why go to this much trouble?

I have heard horror stories of people's rack cylinders leaking and eventually failing, requiring new racks. 750 bucks, dude! I'd make no guarantee that this wont happen, but since the effort and cost are small, it certainly cant hurt.

When should you do this?

I dunno. certainly 95k miles is too long. 50 k miles would be my best guess. and you will KNOW that it is right.........
