Knocking noise Hyundai i30

Happy4all

Lately getting a Knocking noise when driving. Hard to pinpoint where from, but suspect rear passenger side. I thought it might be a wobbling exhaust with a loose bracket, but I have checked under car and nothing visibly loose. noise is there occasionally, sometime noticable driving over speed bumps. Any ideas?

There is not a lot to go on here.

The good news is that if it's coming from the rear it's probably less worrisome than if it comes from the steering/engine bay

First of all, remove any lose objects in rear, check if jack etc is secured.
Then have a mech check the shocks and bushings for play.
Also have mech check the tyres are properly fastened.

I had a clunking over bumps on my old beemer recently. Turns out it was a broken spring. See if one wheel is sitting lower in the wheel arch than the other. This may hint at that.

These have suspension that just fall to pieces over time! Most common for bad knocking in rear is the top mount totally failing and the shock almost coming up through the body.



The front arm on the rear also fails regularly and are a nightmare to change if the bolt seizes in the bush.
