2014 C4 Grand Picasso Exclusive Knocking from steering rack

Post by noworries2004 »

There is a knocking noise from my GP steering rack when i am travelling on bumpy roads. They knocking seems to be getting worse over the last few weeks.

I checked all bushings etc and they are all fine.
Does this sound like i need to replace the steering rack?

Or is there something after loosening in the steering rack

I've been checking your thread but nobody has replied to you yet.

I have a very similar issue on my C4 Picasso (non-grand) which has the same front end and same suspension.

Mine has done 65,000 miles and has all original parts still on the car, except the drop links.

I've ordered full shock absorbers, springs and top mounts which have now all arrived and I'm hoping to get these replaced this weekend. (I am changing them anyway as I want to get the comfort feel of a new car, and recommended to change at 50,000 - which is why I'm replacing all)

For my issue, I'm hoping it's the top mounts on the shock absorbers, as all other parts appear fine and my local garage couldn't find an issue.

I'll keep you updated if this resolves my issue, as changing the shock absorber top mounts will be a lot cheaper than a full steering rack - so you may want to consider it, depending on your mileage and when last changed.

Here is my original post;

Here is also a link with exact details of how to change the top mounts on the suspension for your exact model;

Hi any update on this? I had a knocking when I bought my car 2 years ago and had top mounts replaced then the steering rack repaired. It's started to knock again but only as a feeling through the steering wheel and only when the steering is turning, not when driving straight. Don't want to just start replacing part without good reason.

The steering has gotten worse in my car. Cant drive it now there is defintely 10-20mm play in the steering wheel before it starts turning.
Looking for second hand steering racks now at the moment.
Anyone replaced the steering rack in 2014 grand picasso before?
