Mr G Posted August 22 Share Posted August 22 Hi all, I am getting a strange suspension creak/knock when pulling away and stopping. Its really intermittent and literally just happens when I go to pull away from a standing start or stop, but its not all the time. Its really weird as it sounds like a stretch creak and a little knock, I can't even describe it properly. Sometimes it sounds like its coming from the front, other times from the rear. Car is a 2017 A3 Sport 1.5 TFSI Saloon. Any pointers please? Thanks. Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted August 22 Share Posted August 22 The most likely culprits are the CV (constant velocity) joints. Does the knock become worse when the steering is at full lock? Quote Link to comment Share on other sites More sharing options...

cliffcoggin Posted August 22 Share Posted August 22 Does your car have anti-rock strut connecting the top of the engine to the bulkhead? If it does, check the rubber bush. Quote Link to comment Share on other sites More sharing options...

Hi its probably what is referred to as the Dogbone link which fits from the bottom of the subframe to the engine, you have to remove the splash guard to see it, the bushes for this are mounted in the subframe the lower bush starts to split and thats where the noise comes from, the bushes are a pig of a job and require stripping the subframe out, the shame of it all is the bushes are only £20 each but the labour is horrendous, if the bushes are not to split you can always buy a Powerflex insert that fits in to the voids around the bush and make it solid again, these inserts are about £30 and easily fitted, look on YouTube for how to do it.

Guest Posted October 8 Share Posted October 8 It is front lower suspension arms .. they have rubbers which over time creaks and if they are cracked it will knock metal on metal.. It only will knock when u start reversing and turning and then u go forward and straighten steering wheel either left or right it can ckock sometimes.. Check ball joints... Or if u can hear creak from top it will be shockers bearings which sits on springs.. Spring mounts which goes on top of bearings are usually fine .. strong rubber ..

Its a really strange noise and its doing my head in. I've had the shocker, top mount and drop link replaced, the noise is almost gone when taking off, however in reverse its still doing it when I initially start to reverse, especially when steering is turned. How easy are the lower suspension arms to replace? Quote Link to comment Share on other sites More sharing options...

Mr G Posted 17 hours ago Author Share Posted 17 hours ago Genuinely stumped by this. So far the following have been replaced: - Wishbone - Strut - Drop link - Shocker - Top mount. On another forum I then found this bulletin, so I have now also silicone lubricant sprayed up the buses on both sides. I have literally grease or lube sprayed every bush in sight and still this problem persists. I am now at a point where I do not know what else to look for. Any further guidance would be appreciated. Thanks. Quote Link to comment Share on other sites More sharing options...
