junglism32 Posted April 21, 2018 Share Posted April 21, 2018 Hi everyone, Sorry if this is a repeat post but I can't seem to find anyone with quite the same problem as this. I've developed a quite loud "knock" or "clunk" when taking off or accelerating abruptly in 1st, 2nd and even 3rd at times. I just replaced the rear engine mount and this didn't solve the problem. I can feel it almost directly under my feet in the footwell when it happens. It doesn't happen if I drive very carefully and accelerate very slowly, nor does it happen when going over bumps or any other time other than fast acceleration. I can pump the gas pedal and make it clunk nearly on command once I've released the clutch nearly all the way. It doesn't do it in neutral either as I tried to watch the engine in neutral and as a friend drove it and i walked alongside the car. It doesn't vibrate much other than rough idle a bit either. If anyone has any ideas I'm running out of them! Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Paddy94 Posted April 21, 2018 Share Posted April 21, 2018 Sounds similar to what was going on with my car. Very loud clunk or knocking when taking off quickly from a stop. What it ended up being in my case was a broken exhaust bracket, the one right under the engine had snapped and was letting the downpipe smack off the subframe. Hope this might help! 2 Quote Link to comment Share on other sites More sharing options...
Jordan99 Posted April 21, 2018 Share Posted April 21, 2018 I had this exact issue, mine was also a snapped exhaust bracket! Unfortunately it’s the section of exhaust that has the cat (most expensive but to replace). I just put a jubilee clip on there, holds nicely and passed the mot as an advisory! 2 Quote Link to comment Share on other sites More sharing options...
Paddy94 Posted April 21, 2018 Share Posted April 21, 2018 Yep, sounds like it might be a common issue. Luckily enough, my local mechanic was able to weld mine back together, been fine since and a whole lot cheaper at £30 than getting a new Manifold, Cat and downpipe (All one piece!) at over £300!

junglism32 Posted April 24, 2018 Author Share Posted April 24, 2018 Thanks guys, I did notice one of the brackets had rusted off the exhaust when I was under there changing the rear engine mount. It does seem much louder than this but it could easily just be getting amplified. I will report back. Cheers. Quote Link to comment Share on other sites More sharing options...

Any idears focus 2007 auto Is it definitely from the front? When my rear upper arm bushes went it would transfer the noise through and would seem like it was the front.

Rusty99 Posted March 23, 2019 Share Posted March 23, 2019 I have the same: 2008 focus replaced with new lower arms, dog bone and drive shafts - none of these have solved the clunk. Everything seems good on suspension, no engine vibration. Any previous posts solve this issue ? Quote Link to comment Share on other sites More sharing options...
Kenneth joseph Posted May 18, 2019 Share Posted May 18, 2019 Same on my 2003 focus 2.0L, sedan. Makes a knocking, and loud clicking, rattling noise under acceleration. Struts, axle shafts, sway bar end links been replaced. Next is going to be ball joints and tie rod ends. Haven't checked the exhaust though.

ColW Posted May 19, 2019 Share Posted May 19, 2019 I had similar on my old 2005 focus when one of the rubbers at the rear of the exhaust was snapped. It gave the whole exhaust system enough play to knock loudly towards the front of the car. 1 Quote Link to comment Share on other sites More sharing options...
Boops Posted May 21, 2019 Share Posted May 21, 2019 Mine is doing the same but does it in 4th as well. Has anybody resolved this ? Quote Link to comment Share on other sites More sharing options...
sibaylis2 Posted July 6, 2019 Share Posted July 6, 2019 Hi, i have what i think is exactly the same issue, when pulling away and changing up thru 2nd and 3rd gears, but not really noticed in 4th upwards, but yes a loud clunking noise on engaging the throttle after gear change, also when just rolling in traffic in any of these lower 3 gears and just tapping on the throttle, clunk clunk clunk, very annoying, its the second st180 i have had so i compare everything to the previous one that had no noise whatsoever. Have had droplinks, front drivers mount and drivers side drive shaft (which had 3-4mm play) all replaced, rear engine mount and all brakes checked and the problem still persists, am now going for new brake discs, hoses and caliper guider slider pins as i know the brakes are a bit low and discs corroded on edges so they need doing but also will see if there is a difference, if its still there then i will have the whole exhaust system checked, mountings, brackets and heatshields as i have heard these can all be symptoms, but if anyone has any ideas then be glad for the input. Cheers, Simon.B Quote Link to comment Share on other sites More sharing options...

WireyWhenWet Posted August 17, 2019 Share Posted August 17, 2019 The front exhaust mount from the down pipe is most likely to be at fault, usually the hanger will rust through and drop lower but still 'look' okay without having it jacked up and being able to get a proper shove on it. Majority of Focus 'clunks' when accelerating end up being that bounty allowing the jerk of the car to shift the down pipe just enough for it to knock the sub frame, making it sound a heck of alot worse that it actually is. 20 quid at a local to weld'erup should do it if that's the case! 1 Quote Link to comment Share on other sites More sharing options...

Mr tattoo Posted March 26, 2022 Share Posted March 26, 2022 My problem sounds like everyone's, was fine until I jacked up the car ,now groans and knocks under excelaration, not if I push the clutch in or just rev the car while driving, changed sway bar stability struts and all the other bushes seem good, it's highly annoying Quote Link to comment Share on other sites More sharing options...
