Name my knock / rattle

[Stutopia]

On some of our excellent B roads today and I started to hear knocking, always at low speed, always on a rubbish road surface. Is this the fabled banana bar that I've read about but never actually heard before? Thanks for listening, any help is much appreciated.

 

Thanks, Stu.

Yep that's the B A N A N A B A R ... try left foot braking just to confirm ... the rattle should stop

[Keyser]

I call your knock /Rattle - Ziggy

 

Hope you like the name

 

 

Yes had banana arms go - no did not sound like that - well they did but it is almost to often, so I suppose it would depend on how many bumps were in the road

 

Only other thing that I have seen and it sounded a bit more like that was a very badly worn drop link.

Let's have a tenner on it Chris ?

[Stutopia]

Thanks both. Keyser, that's a compilation of my best knocks from 10 minutes driving, not just one stretch of road. Typically half a dozen to a dozen knocks when rolling up to junctions/lights on poor roads.

 

Drop links were done just under two years ago but I see from one of ATTAK's old threads it's not inconcievable for replacement drop links to fail in that time? But it still feels too soon

Can't we have a soprano?

 

Nah - I did say the only reason it sounds wrong is it was .... errrr ....... rattly but if it was a very bumpy road it would, I find banana arms tend to be a knock for each bump but without a test drive I would never put more than £1 on it

Unlikely they failed already - unless they were eBay ones that are actually cheap replicas and are made out of chocolate

 

I didn't realise it was your greatest hits album so could well be banana arms.

 

 

You just cost me £1 - I HATE YOU

[Stutopia]

Is there an easy way a mechanical re-tard can see if it's the bushes or the bar, without a jack, pry bar or any real brains

[ATTAK Z]

Chris you've done plenty for the club over the years, so no bet ... but if I'm wrong on this one, I'll deffo put a tenner in

Genuine ZMANALEX ones, not ebay chocolate.

2 ways to test the drop links -

 

1. Jack up the car - or put 2 wheel on the pavement reach under grab the drop link - if you can shake it and it clicks then it is FUBAR.

 

2. Remove one end of the drop link (requires spanners) zip tie the other end safely out of the way, go for a SLOW drive, if the rattle is gone then they are FUBAR

 

 

Even with a pry bar it is hard to test the banana arm - even some mechanics miss it, the correct procedure is in the manual though

Stop sitting on the fence Attak Z - always sugar coating things you are!!!!!

[Stutopia]

Thanks both, forget the tenner chaps, I owe you both a large drink

Welcome to the world of suspension arm replacements. My cars a veteran at this lol

[iwanprice12]

I've got a similar sound coming from my driver side. The bush on the banana bar went on the passenger side last year before MOT. The knocking I seem to still be there when braking on a rough surface, so I'm guessing the droplinks have gone.

It's both the drop links and banana bar bushes.

Now you owe me a large drink.

Sorry, but it's neither ... it's the ball joint on the compression rod

[AMT]

Bingo attacks got it lol the rattles the ball joint part of the arm

Tried this, drop links were solid as a rock. Thanks

100%, definitely, un-questionably the compression rod bushing.

Wow, that's a definitive stance. There's not even a 1% chance it is the ball joint end?

Could it not be the bell end ?

[Stutopia]

Thanks chaps for confirming my banana bar, ball joint end. Replaced the arm today, play was in the ball joint and now the knock is gone
