Title: Front End Clunk (Subframe Bolts Done) *Video Inside*
Post by: waqasr on November 06, 2017, 03:39:26 pm
Guys I need help locating the source of this clunking. It does it over speed bumps and over rough roads.

The subframe bolt fix has been done. I did have a look at the drop links (adjustable joms) and the rubber boots were completely failed so I replaced droplink and no change at all. the Car is on AP coil overs and not lowered much.

I know when the coilovers were done, febi top mount and bushes were used and Ive got a feeling its these but want confirmation before I take it apart.
Theres also a clunking when I brake while reversing, im assuming this is related to the worn part.

You can hear the clunk clearly at 00:10 and it happens on both sides, more on the drivers side though.


Also the noise when braking in reverse, this is me breaking on and off to make the sound.

Have you checked the CV joints?

I have looked at them, they seem fine and dry, not grease apparent or any cracks in the cv boots.

That's definitely not subframe but sounds more like a your anti roll bar bushing  :thinking:

Can they be that noisy while rolling so slow? What about top mount bearings?

After seeing how much of a headache it is to do the bushes, Im really hoping its the top mount bearings!

I not long had a an issue with my arb coming loose damaging the bracket and believe me it was bad. I was thinking too mounts but didn't want to say that as it way not be. Does your car happen to pul to the left or right and you struggle to bring in back to straight position?.

Nah it doesnt pull to any side, runs perfectly straight. Oh god and tonight theres a new sound, just drove 140 miles to Birmingham and getting close to my destination, has to pull a 3 point turn and as I pull away I hear a tick tick tick and then a loud clunk! Really need to do something about all these noises

Clicking whilst doing a 3 point turn sounds like a CV joint. Get it in the air and give them a good grab and look for any abnormal movement

I can't view the videos in work but your original description sounds like what I had on mine, after I changed everything on the front end of the car hunting for it..... and it turned out to be the steering rack knocking

Doesn’t mean the cv joint is sound though

Sorry just to clarify it was after I turned the car around so I was driving straight when it happened, theres no clicking on turns.

Id say dry is the opposite of fine  :wink: sorry, I know you mean the boots. Just reads funny.

Lol I guess your right. But still no luck with this. Think I will try changing the top mounts and bearings in the coming weeks and see if that sorts it.

Today I took both drop links off and quick drive the noise is still there, so I guess that rules out arb bushes?
Title: Re: Front End Clunk (Subframe Bolts Done) *Video Inside*
Post by: Shoduchi on November 09, 2017, 01:22:31 pm
Yeah, I think so as well. The ARB wouldn't move much without the drop links connected.

Try tugging the tie rods with the car up and wheels off, see if it replicates any of the noise

My moneys on it being some bolts being loose..... maybe your caliper / carrier bolts...  :signLOL:

Mine makes clicking/clunking noises at slow speeds when braking, forward and reverse.  It's the front calipers/pads.  Just haven't been arsed to sort it yet.

Inner CV joints click under load, usually only when pulling away from a standstill - where the load is highest on them.  Worse on hill starts.

Outer CV joints click/knock/jolt when cornering close to, or at, full lock.

A worn rack and pinion usually feels vague around centre and knocks over bumps.   You can confirm by jacking it up, putting the steering on full lock and shaking the tie rod on the fully extended side violently.  There should be no play.  Repeat on the opposite side.

200nm + 180 degrees. They never come loose.  I think someone forgot to torque it  :grin:

I've done that with mine once and quickly took the wheel off and tightened it  :doh:
