Ford Ka+ Active - Crunching / crushing sound from front of car - Joneb
I have a ford ka+ 2018, owned it for a week and noticed when I’m driving over speed bumps there’s a strange sound from the front left of the car.

I have googled the issue and applied Wd40 specialist silicone spray to the control arm bushes and took it out for a test drive and it’s still the same.

I’m not very knowledgeable about cars and spraying lubricant on the bushes is something I’ve never done before, I’m concerned if I’ve done the right thing? Surely it won’t hurt and help the bushes even if the actual issue isn’t them?

So I still have the noise, is it due to the cold weather ? I mean the car has only done 10k and looks pretty new underneath.

Any help would be great, thanks

If you bought it from a garage I would take it back without further meddling.

I did and I probably will, i wanted to try and resolve it myself to save trips to the garage,

Will the silicone spray cause any issues to the bushes ?

Can't see why it would, silicone spray is a recognised product to use on rubber window and door seals.

This is a common noise on a lot of cars its the antiroll bushes, the bushes need some grease rubbed around their surface then refitting this will stop the noise. Needs to done when the wheels are hanging free not with the load on them. You spraying them with lube will not have done any harm so don't worry.
