Knocking noise front right suspension

[Pete940]

A single knock usually occurs when braking, and sometimes a pretty big knock/crack happens when steering at low speed. A knock can also happen over sizeable bumps.

Top mount bearing for steering knock? What else should I be looking at?

On a side note, I get a silly amount of wheel "hop" at one of the front wheels when turning a tight radius at low speeds. Probably due to a variety of things. Just wondering if anyone else experiences this? It's a bit unpleasant, kinda like having a welded diff!

I think i would be looking towards the bottom ball joints. Jack the car up and check for play using a pry bar.

I agree with bottom ball joints but also have a look at the track rod ends and also check the suspension bushes.

Changed bottom ball joints, no improvement.
Changed drop links and anti-roll bar bushes (needed to be done anyway), but still getting the knocking noises.

It does kinda sound like it's coming from the top mounts, but I'm not sure how a top mount can create such a noise. Any thoughts?

Not sure if the top mounts would make the noise you have unless they were completely shot. Mine used to knock a bit over small bumps and thats was down to the original rubber compressing slightly allowing some free play. I have found a way to take up the movemement but it's only OK to do this if the bushes haven't already split at all.

From what you say about the tyre scrubbing I would suggest looking at the drag strut bushes, espicially the bigger ones at the lower arm end.
Another possibility is that the shock absorber is worn.

Cheers Steve.

Sorry, it's probably obvious, but which ones are the drag strut bushes? Honestly hadn't heard of that term until now.
And when you say the bigger ones, are they the most rearwards ones?

Thanks
