S60 Steering: graunchlng

[jamena]

Hi when i am manoeuvring on full right hand lock i am getting a metalic graunching sound from my O/S/F. I do not get ìt on my full left hand lock any idea's.

wheels rubbing or the steering stops have shot perhaps or the steering limiters need a bit of grease on them

Are steering stops and steering limiters one of the same or are they two difference components.

they are both different components which touch together when you turn the steering stop is the rubber item that is bolted to the control arm the limiter is the metal arm that is bolted to the hub carrier or it could be the other way round

could be the CV joint failing.

Wouldn't it graunch on both locks if it was a failing CV joint?

The o/s/f when at right lock has an angle greater than it is when at left lock. Its related to the Ackerman angle which when you string an imaginary line through the front swivel point to the centre of the rear axle line, the outer track rod point intersects this line and the steering arm angle traces along this line, its this steering arm angle (the bit that track rod connects to) that gives a difference in angles depending on left or right lock on a given side.

eg. When going round a right hander the o/s has the tighter arc to follow and the n/s conversely has the lesser arc. thus differing steering angles are needed between sides.
Ackerman angle facilitates this need. (Much more to it but this is the basics of how you get round corners and keep tyres relatively intact)

All this may account for less stress and no graunching on o/s cv when turning left, as it is at the lesser angle.

Check the brake disks are not rubbing on the back plates due to corrosion build up

Could be any of the above. Eliminate the simple things 1st, check in the wheel arch for any rubbing from the tyres, and make sure the back plates are free from any loose rust and are not catching the discs. You can swap the lock limiters from one side to the other, this will possibly stop them rubbing, as it did for me. It will take you all of 5 mins to swap them over, including a cup of tea for a quick break. 👍
