Stafford_Mart Posted November 24, 2017 Share Posted November 24, 2017 Hiya Having now been struck down with the dreaded knocking noise from the front suspension and thanks to Z Attack who has supplied a picture of a new banana arm I now know what I'm looking for. I had the car checked out today and was told that everything was as tight as a drum and next months MOT was a formality....but didn't know where the knocking was. So I've had the wheels off myself and took a couple of pics of the arm bushes. They look solid but seem to have something around the outside of the bush that looks like its coming out. I don't want to look a complete prat but is this the bush on its way out or do they look normal. Any advice will be much appreciated. Thanks. Mart.

ATTAK Z Posted November 24, 2017 Share Posted November 24, 2017 It'll be the ball joint that's the problem meaning replacement of the complete arm ... my advice ? bite the bullet and replace the offending side ... and then save up to get the other side done It's notoriously difficult to diagnose the knocking compression rod problem !!!

Stafford_Mart Posted November 24, 2017 Author Share Posted November 24, 2017 Hi ATTAK Z Thanks so much for the advice, I'll see how much the garage charges and get both done at the same time. In your opinion is it worth getting some poly bushes and starting the gradual replacement of stock ones....pushing the banana ones out of the new units and gradually doing the control arm and upper wishbone arm. Incidently, my apologies for getting yur name back to front....oops. Quote Link to comment Share on other sites More sharing options...

mr v6 Posted November 24, 2017 Share Posted November 24, 2017 I also had a horrible metal on metal clang. I had that same bush appear to be working it's way out of the arm. I had my local mechanic remove the arm & press in a new bush I supplied him: Quote Link to comment Share on other sites More sharing options...

Stafford_Mart Posted December 14, 2017 Author Share Posted December 14, 2017 Quick update on the above suspension knocks. Had the car serviced this morning and MOT'd too. Also had the banana arms replaced and guess what.....that knocking is still there. Now having a bit more exploratory work carried out to try and get to the bottom of this. Otherwise I suspect the radio will be on full blast for a while until it is sorted. Worst thing with any problems is the not knowing.

MDMetal Posted December 14, 2017 Share Posted December 14, 2017 is it a light or heavy noise? the heavy clunk is the banana arms the lighter clunk or clang are the droplinks. Quote Link to comment Share on other sites More sharing options...
Stafford_Mart Posted December 14, 2017 Author Share Posted December 14, 2017 (edited) I think that might narrow things down a bit. The banana arm bushes were on the way out anyway so no money wasted there. It isn't a real heavy clunk, lighter, more like someone hitting the chassis with a small spanner. it doesn't happen over speed bumps or pot holes either. Is there any other way to confirm that it's the drop links? Edited December 14, 2017 by Stafford_Mart Quote Link to comment Share on other sites More sharing options...

Yes ... take them of and if the knocking stops, it's the drop links. Seriously. Quote Link to comment Share on other sites More sharing options...
Stafford_Mart Posted December 14, 2017 Author Share Posted December 14, 2017 Yeah that makes sense, didn't think of the obvious I'll try this and get back to you. At least they aren't too expensive to replace and I guess easy to swap too. Quote Link to comment Share on other sites More sharing options...

mr v6 Posted December 14, 2017 Share Posted December 14, 2017 What about the bushes & balljoint on the lower control arm? Quote Link to comment Share on other sites More sharing options...
Stafford_Mart Posted December 14, 2017 Author Share Posted December 14, 2017 I haven't looked at those yet, they all seem solid and bushes are where they are supposed to be. Compression rods were dodgy anyway so going for drop links next. If that fails then there's only the lower arms left to replace. Fingers crossed for the last 2 options.

Stafford_Mart Posted December 28, 2017 Author Share Posted December 28, 2017 Hi guys and belated Merry Christmas. Good news...got a pair of drop links (Bilstein Febi) and got them fitted this morning at a local tyre and service centre for £30. The rattling is now deceased and just road noise and purring V6 to listen to now. Thanks to all who advised me on this. I can finally start on the things I want to tidy up now....door trims, sound deadening and a nice "Z" partition panel for the boot that I've seen on the forum. Happy Z018 guys.
