Front end knocking query

[TomLum]

Hi i get some knocking from the front end of my 2004 Zed. Usaully when going over uneven road surfaces. Ive done some searching and tried going over these surfaces with brakes applied and I still get knocking.

 

What are the usual suspects? I was going to get bannana arms but thats expensive if there not the problem.

 

Droplinks?, bushes?

 

Thanks, Tom

Hi Mate, am on the same boat. I changed the drop links and it wasn't the issue as they are still knocking. I think the issue is the ball joint which means I will need to get a new arm.

Most common are either the Compression arm bush which can be replaced without changing the whole arm or the ball joint on the arm in which case you will need to change that.

 

Drop links are also worth checking

You can usually see if the compression arm has failed as the rubber pokes out or the arm itself drops down.

 

Significantly cheaper to get the bush replaced but make sure its not the ball joint first

I am getting a similar issue. I got the car up over the weekend and had a fiddle around it seems to be the drop links. I've just received a set whiteline front drop links from Clarke Motorsport, hopefully this will resolve the issue.

 

I will provide some feedback once they are fitted.

Banana bar . Usually LHS first. Every time . Guaranteed.

Ouch, They difficult to replace? How can you find the fault on the banana arm?

Nope

 

How can you find the fault on the banana arm?

 

Notoriously difficult to diagnose both on and off the car, but trust me a new arm will fix the problem

ETA by all means fix the drop links first as this is less costly to do, but nine times out of ten it'll be one of the banana bars

I'm pretty sure it's the nearside that's knocking to. I suspect banana arm then!

 

Thanks for the replies

Let us know when it's fixed

[Ewen@Clark Motorsport]

We have new OEM Nissan compression arm bushes in stock they are £29.99 each.

 

Let me know if I can help

[Rock_Steady]

yeah mine does this too. I'm just going to change everything! To hell with it. Can't be arsed in playing Colombo trying to find the offending article.

I've got knocking coming from the rear and front offside, changed all my drop links on the weekend and the knocking is still there . Think I'm going to try the compression arm bushes next

[Ramma]

Me two have knocking from front end, seems like it's from the o/s f. Checked bushes on both sides and found the n/s f compression bush gone, the bush not in arm. Complete arm fitted but still knocking at low speeds on rough ground. Next was front and rear ARB links replaced. Tried new shocker but still the same. Any advice would be much appreciated
