Power Steering

Post by maricardo on Sun Feb 12, 2017 11:15 am

I have a 2013 Sussex Duo on Peugeot Boxer chassis.  On initial start up I get a pulsing (jerking) backwards and forwards on the steering wheel when manouvering.  This lasts only for less than half a minute and then the steering returns to normal and with no further problems.  Any ideas what could cause this?

Check pas fluid level (if you haven't already done so)

And if it's low, or anything other than nice and clear and clean looking, find out why! If it's low, the fluid ~should~ be going somewhere visible - though if the steering rack itself is faulty it may be filling up the rubber gaiter(s) rather than coming out onto the ground...

My 2016 Peugeot does this, and so do many others, with my engineering head on its as though the system is opening the pressure relief valve. Apparently it's not uncommon and difficult to get fixed. I'm ignoring it like many others it would seem.

+1

As it only occurs at start up when first manoeuvring, I am ignoring. Used to happen on my Symbol and never developed into a serious problem.

Thanks for comments so far.  At least I am reassured, as it happens with other Boxer owners.  It is only evident on first start up.
My main concern was that it may be the start of a major power steering fault.

An interesting point.
Our van had a rather noisy steering pump. I picked up a can of STP steering fluid that perported to reduce pump noise. This was a light brown liquid that looked very much like the fluid in the system. I sucked the reservoir dry and put the new fluid in. This turned the growl into a wailing howl!

I sucked it out and filled up with traditional ATF. Much quieter. I worked the steering lock to lock, sucked the reservoir dry again nd refilled with more ATF. Quiet as the grave now and the fluttering has gone too.

Air entrainment maybe the problem, or low viscocity.
Check the simple things first.
