Hello,

You guys have been so helpful to me with my previous issues - I truly appreciate it!

However, recently when driving on the motorway, when my steering wheel is turned left, I hear a strange noise coming from the back end of the car. If my hearing is on point, the noise would be coming from the back-right.

What could it possibly be? Power Steering fluid?

Noise doesn't occur when turning steering wheel to the right.

I don't know where to start from or what to replace.

 

If you are positive the noise is coming from the rear then it can't be power steering fluid. That is all up front. There are a few inspections you can do to narrow it down.
1. Take a look at the rear of the vehicle from about 8 to 10 feet away at the rear.
Does the top of the tire appear to look like it leans in towards the top of the tire?
2. Inspect the tread wear for the right rear tire. Does it look like it is wearing different on the inside compared to the outside?
3. Lift the right rear tire off the ground. Grasp it at the top and bottom and rock it back and forth. Then do the same things from the left/right sides. Does it have significant movement?
A tilting wheel and abnormal wear would be a failed upper control arm. The significant movement would indicate a bad wheel bearing.

Try out those inspections and get back with us for more information.

 

Hello avern1,

Thank you for the suggestions.

There was severe inner tread wear of the tyres, so I got all 4 brand new tyres fitted and aligned if wheel alignment included.

The problem still continues when I turn my steering wheel to the left..

Any other suggestions?

 

Tires and alignment does not cure mechanical component problems.

 

Like Avern mentioned, check the control arm and wheel bearing. That is a good place to start. If you replaced tires that had a non-normal wear pattern the issue that caused that wear pattern is still there. Address the underlying problem soon or your tires will soon wear out the same way.

 

The sound is in the back of the car, in only one direction?


Before you go crazy, check the anti-roll bar bushings and end links on the rear.


Also, if your rear tires are leaning in at the top, check the rear front upper and lower control arms. There is a whole thread here on adjustable replacements for the upper arm, most of the suppliers here on the site have the lowers in stock.

 

was the inner tire wear on both rear tires?
my bet is lower control arms.
easy, quick and cheap to replace
do it sooner rather than later.
that may not be the cause of the steering sound but it does need addresing

 

When you turn left, the car will lean right, so the left side tire and suspension drop down and you hear the noise, that mean some things broke or loosed; Anti roll bar link? Coil spring? The shock bolt? Control arm bolt? Jack the car up and check those places.
