Tell me more about my Hilux please

[jdv]

Hi Hilux owners,

I have not owned a Hilux for many years now, so my recent;y acquired 1998 SR5 extra cab have some gadgets that I am unfamiliar with - I think. I have tried to get hold of a workshop manual so that I can read up on it, but have not found one yet. So, I am wondering who can tell me what I hear on it - described as such: When I reverse out of my driveway (a bit of an incline) and turn sharp to the right, I hear a sound briefly that sounds like an electric servo of some sort. It goes whoooooor and then stops, almost like something that winds down briefly then stops, this is the only time I hear it and sounds like a "good noise", not that something is faulty. At 60 000km I don't think something is "broken" and everything works. What is this? Thanks, regards, JD

Sorry, that's a 2008 model (I seem to be stuck in the nineties! )

Most likely just the power steering pump. Are you at maximum lock when turning out of your driveway? The sounds is perfectly normal anyway.

Hi T_Money, thanks for the reply. No, I don't get the impression that it's the steering pump: You are right, I have the steering turned at the point that I hear it, but I don't think I am at full lockas the road is reasonably wide and I tend to reverse into the left hand lane, not requiring a very sharp turn. Its also almost like a fixed duration every time, not dependant on how fast or long I drive out, turning the wheel. When I saw your post, I jumped into it, started it and turned the steering full lock to both sides, going forward and back about a meter each time, with the car level - I just heer the TSSSSSHHHH sound when I get to full lock, not that servo type sound. That sound is heard when the front wheels goes into the curb, the rear wheels slightly higher up on the tar. If you are familiar with the sound of an outboard motor on a boat being lowered - it almost sounds like that but not as high-pitched. It does not worry me, I am just very curious of what it is.

The only other thing it might be is the arcon compressor kicking in for the first time. Makes a similar type of sound? yourn your ac off before you drive out of the driveway and see if the sound is still there. Either way it doesnt sound like anything bad.
