Car Forum / Volkswagen / Water Cooled Volkswagen Cars / May 200786 Jetta GLI Power Steering Noise
My wife has a 1986 Jetta GLI. The power steering has always made a whining sound when the fluid got low, but I recently replaced a couple of leaking power steering hoses, and now the steering pump seems to whine all the time (when making tight turns, not straight driving). At the same time, the steering feels a little "squirrely" despite new shocks, alignment, suspension adjustments, etc. Almost like the power steering is a little hypersensitive or something. Any idea whether the pump or the rack is at fault? Both are ridiculously expensive, though the pump would be a lot easier to replace. :) Thanks, Anthony > My wife has a 1986 Jetta GLI.

When you replaced the lines, you may have (somehow) trapped air in the rack. b) A kink somewhere in some line that overloads the pump causing the whine. c) Something dislodged when you did the work and is restricting a line. You might try a junkyard pump, you would be no worse off than now at a much lower price. Depending on how strong and resilient your wife is, you might just live with it until one-or-the-other fails. Typically the steering will get harder and harder giving *some* warning before final failure. But I would hate to have anyone driving off an highway ramp and suddenly have no steering because something seized. But, and I have to ask, you did have the *FULL* (4-wheel) alignment done with all that suspension work, such that toe-in and camber is present and correct? One of the symptoms of bad alignment is "loose" steering, even a certain jumpiness. Peter Wieck Wyncote, PA Peter, >> My wife has a 1986 Jetta GLI.

It said to just turn the wheel lock-to-lock a few times to bleed the air out of the system. > b) A kink somewhere in some line that overloads the pump causing the > whine. I did check for kinks.

I tried to clean everything up nicely before taking it all apart, but... > you might just live with it until one-or-the-other fails. That's basically the mode we're in now. It still drives nice, but there's just something that doesn't "feel" right about it. She notices it more than me since she drives it every day. > you did have the *FULL* (4-wheel) alignment done with all that > suspension work, such that toe-in and camber is present and correct? Yep, we always have the full 4 wheel alignment done. Everything checks out fine. She'll need new tires soon, so we'll be getting another alignment then too. In any case, at least the hoses aren't leaking! :) Thanks for your thoughts, Anthony did you flush the system out? did you use the proper mineral fluid? I will ASSuME that the belt is not making the noise. it could be that the ps pump is bad! :-( > Peter, > [quoted text clipped - 46 lines] > > Anthony |
