Default 84 fluid changes... Need guidance

Hi all,

Well, I have a week off from work coming up and I'd like to flush the power steering fluid, brake fluid, and rear differential fluid. Can anyone give me the proper procedure and best products to use for power steering flush, brake flush, and rear differential flush? I don't want to screw it up. I've never flushed these three systems in a car before.

Thanks in advance. Pete.

Buy some speed bleeders for the brake calipers, makes for easy flushing. Napa should have em.

I use Valvoline Synpower for my brake fluid and power steering fluid. It is clear as water.

For the brakes, do yourself a favor and purchase a set of speedbleeders and the bleed becomes a one man job.

For the power steering, use a turkey baster and drain and replace with fresh fluid, turn wheel lock to lock, drain and replace and repeat one more time.

Bingo, you are done.

For an extra boost of confidence, I'd also reccommend the Helms FSM. You can get one at a nice price at

To get the old fluid out of the diff, use one of those small fluid pumps backwards, add a longer tube to the suction side and stick that into the fill hole. If you're careful you can get most of it out.

The diff has no drain plug.

You can get a decent one at Harbor Freight tools for under $13. That's what I did.

Use a turkey baster to suck the fluid out of the PS reservoir.
Do it a few time replacing the fluid with new stuff until it starts coming out clean.

That's the easyway to flush the PS fluid.
