    Noise when turning steering wheel to its limit

    Noise when turning steering wheel to its limit 15th Apr 18 at 4:11 PM
    Hi,

    I'm currently looking around for a used car. Whilst testing a car today I noticed a whining or screeching noise when turning the steering wheel to its extreme (done when maneuvering out of a tight space). The noise wasn't present at any other time. I was told that this was normal for cars with hydraulic power steering and steering wheels should not be turned to their extremes.

    I'm not knowledgeable about cars but have never noticed this on any other car I've driven and have never heard that steering wheels should not be turned to their extremes.

    Was the dealer fibbing/ignorant or is there truth in what he says?

    If the noise is indicative of a problem, what the best and worst case scenarios for a fix?

    Cheers

    Thanks. So from your reply I take it that its likely to indicate a problem of some sort even if only present when wheel is turned to its extreme?

    It may have been the belt slipping, I have had that issue before.

    Probably needs a new drive belt, the dealer is correct, you shouldn't hold power steering against the stops. It causes a huge load on the system, as it is trying to turn the wheels through a physical stop, which can burst pipes, overheat fluid or cause a marginal belt to slip.

    Thanks. So just to clarify...

    Dealer was correct to say its not good practice to turn the wheel to its limit but he was not correct to say that the whining noise is normal and nothing to worry about?

    Hes right in that you shouldnt turn them to their extremes however they shouldnt make screeching noises when you do.

    That suggests it needs a new power steering drive belt at very least - not much fun if it snaps.

    Whining or screeching, which was it? If its whining then that is normal at full lock when you're still applying pressure to the steering wheel.

    Good point, but either way if the whining was noticable to the extent it could have been mistaken for screeching or was combined with screeching then there is an issue there that needs to be resolved.

    Some cars seem to make that noise but if you have a choice, buy one that doesn't.

    In any case it was a high pitched noise very obviously audible above the engine noise. So obvious the dealer mentioned it before I did.

    After returning home I tried momentarily holding the steering wheel to its extreme position on another car and I could barely hear any noise from the steering, certainly nothing I would have noticed if I wasnít trying to listen for a non-engine sound.

    If you are turning in tight spaces it is perfectly reasonable to turn steering to its extreme and hold it for the duration of the turn.

    A bit of grumbling is normal, but screeches and nasty loud noises are not.

    Dealer is gilding the lily - he's right you shouldn't sit there holding it against the stops for extended periods of time, but he's making it up suggesting it is wrong to use the steering to its full extent.

    How old is the car you are looking at?
    what is the make, model?
    Get the dealer to check / put a new belt on and check the steering pump,
    if he is unwilling to do this, he will be a problem if you have problems later.
    if its a newer car it may have electric steering and if it has walk away.
    We may not win by protesting, but if we donít protest we will lose.
    If we stand up to them, there is always a chance we will win.

    There's no reason not to turn the steering to full lock. There are lock stops to prevent any travel outside of the normal range, and the assistance isn't "trying" to do anything - it's simply reducing the effort required for you to do it.


    Healthy hydraulic power steering will make a little more noise on lock - but very little, a bit of a hissy-whine. Nothing will break, no matter how long you hold it on full lock, as you would do in many perfectly normal driving manouvres.



    If it's making a squealing, then it's probably the belt. It may simply be a little loose or it may need replacing (both are a routine service job - if that's been neglected, what else has?). If it's been slipping for a while, the pulleys may be glazed, causing a new correctly tensioned belt to slip - a quick sanding of the pulleys will help. Modern multi-v belts are massively less likely to be slipping.

    Surely all power steering systems are designed to allow the driver to apply full lock without stressing the system?

    I regularly apply full lock during three point turns, reversing and parking manoeuvres etc.

    I've never heard an unusual noise or had a problem in many different cars over many decades.

    Be very cautious with this car and be prepared to walk away.

    "They all do that sir" is the standard secondhand car dealers answer to problems.
    Personally, if I'm not happy with anything on a car I'm looking at I walk away.
