Weird clunk
 

Has anybody experienced an intermittent loud clunk. It has happen three different times. First time it happened, I parked the car went into a story for 5 minutes when I started the car about 5 second later I heard this loud clunk coming from the front end of the car. I got out of the car to check on it because it sounded like someone threw a rock at the sheetmetal or similar. I coudn't find anything wrong so I forgot about it. Then there was a second time in my garage after starting, but still nothing visible. The third time it happend I was wearing thin sandals and I felt the clunk through the floor board on my left foot, left of the brake pedal. I jacked up the car and still found nothing wrong.

Anyone else experienced something similar? I've had the car since Novemeber and it's happened three times.

I've have the samething happen on my Ford pick up truck. It's like a muffal cluck in the front of the dash. Found out its the A/C opening and shuting vents. Try turning off the A/C before shutting down and listen, it sure not happen. Then leave the A/C on and shut down and restart. You will probaly hear it again. This might be your problem or it might not, just some helpful hints.

The clunk is very loud and coming from the outside of the cabin. I have tried to reproduce it with no luck...it just happens when it happens. Last time I felt it resonate through the floor board, but can't figure out what in the world is causing it. It kinda feels like when you leave the parking brake on and the car sits for a long time...some cars have the pads stick and when you move the car it clunks...well, it's kind of like that but in the front and it's not the brakes. Very strange.

I was going to say the e brake cable was freezing, but then I realized where you live. Might be sticking somehow though

I've heard the same thing on my every now and then. I've yet to figure out what is causing it.

yup somewhere under the hood drivers side , I have to let my son start it up for me to see where BUT he may just drive off ? almost everytime I start it up now !

Well, it makes me feel better that someone else is having the same issue. At least I'm not imagining it. Please keep me posted on any findings.

I hope we can try later so I know what to or how to state my concern
I didnt here just now but I think it could be the master cylinder maybe even related to as why the brake fluid wants to leak out of its container ?

Here is a link to a Ford Mustang recall related to the noise -

No, that's a different problem all together.

It one of those take in thing sorry we don't here it Jack, so every time my son is with we try Nothing , so when I'm alone ker Klunk drivers side I think like maybe an air flap in the AC unit ? of the master cylinder ?

How mine Clunks - every time
 

All, I have the "pop" in the front of my car I think we're talking about. Here's how I get mine to repeat itself.
1) jack up the car on the left-front corner (jack just behind the wheel)
2) let the car back down
3) jack up the car on the right-rear corner
I'll make a good "pop" every time! and it's the sound I hear on hard right corners. I've slid under the car to try and find where the noise is coming from, and it doesn't appear to be from the suspension. Unibody cars can have a sheet metal panel "pop" when it is stressed, and that's my guess now. I actually have a video with sound of this problem, since it's so easy to repeat. I'll sort out how to post it (it's a 9Gig movie).

Anyhow,
Jim

Makes sense. I haven't heard mine in a long while. Maybe the sheetmetal finally settled:dunno:

Here is a list of problems I've had with my pony. I still love the heck out of it though:

1. Weird clunk aforementioned
2. Clunk in front end while hitting bump or crevice on road
3. Clunk in the Driveshaft or trannie, sometimes when put in gear, and sometimes when it downshifts from second to first (auto)
4. Problems with Hood Scoop lifting...not fitting flush
5. Front bumper cover in the bottom part, coming loose underneath
6. Sometimes, the driver's window makes clunk when rolled down
7. The coloring on the sheetmetal is not the same shade as the plastic covers, it appears yellowish in color

Any others?

It's amazing that I have seen or spoken to at least 25 people that have the front end clunk and Ford continues to ignore everybody. I reported this on day one of receiving the car and have gone to the 3rd highest level and they have all been trained to give the same answer:
(It's the natural characteristic of the Mustang!!) what BS!! :bs:

Like you I really like the car and continue to live with it but do find myself not driving the car as much as I would like because of the clunking. I'll probabably keep this car for many years but have convinced myself I will not purchase another Ford Product in the years to come. I will also continue to let everyone know when I can about the way Ford contiues to ignore problems from new car buyers.

I get a loud clunk in the left rear every time I go over a bumpy road it seems. Sounds like the suspension though...

I have heard this too. Can't put finger on it.

Found this TSB on another site, Could it be?

RunningWild:

Thanks for the TSB on the front end noise. This is what I have been waiting on. SO much for my local dealer keeping an eye out for me. Now I can take this to him and show him how to fix my problem and let him know how pleased I am on him trying to take care of his customer!!

Thanks Again!

Holy crap!!! (Can I say crap here??)
Thats what I have!! I took it in to the dealer and they replaced the control arm, yet I still have the squeak/grinding noise. Grrr...
I cant take her back in til next Thursday (ill be out of town) but man thats why I love these boards. Friends helping friends. Thanks!!! :metal:

Holy Smokes Batman! That is the other clunk I get when going over bumps. I took my pony in when it had 3k miles for its firts service and told the service manager about the clunk...he said it was normal, just like he said that the good scoop lifting was normal, just like he said the engine ticking at idle was normal. Well, finally the great Ford engineers:screwy: figured it out. One down, a few more to go.

Problem Fix: Found You?
 

Yup. CalStang has the same low speed bumps, front end clunking sounds. Thanks to this Forum, printed out the Ford TSB 07-18-2 on this problem and yesterday took it to my area Ford dealership. They test drove Cal and agreed that both of the front upper strut mount assemblies need to be replaced with the new revised versions. They also stated that we were the very first Stang owners to bring this concern to their shop's attention. The new parts were ordered and a job ticket written up for a scheduled warranty installation. Recommend to all of our fellow Forum Stang owners with like front end clunking problems, print out the TSB 07-18-2 and take it to your Ford dealership for a test drive, to get this resolved. Will post a followup on the final results of this problem's resolution! Wish us luck on this. :nice: We still just love our CalStang! No regrets on our purchase at all!! "RC"

Well it took my dealer 1.5 days to add lithium grease, which they called "a special grease they needed to order from Ford". In that whole time they had my car, they had to call over to Ford directly to find out which grease it was they needed to add to the driveshaft. :screwy:

PS CalStang, did they tell you how long it would take to get the parts and fix it?

According to the shop foreman/head mechanic at my dealership, the front driver's side clunk that occurs intermittently (even if the car is at rest) is definitely being caused by some sort of vent/vane connected to the HVAC opening and/or closing. He tracked it down and said it was a normal function; nothing to worry about.

I, too, get an occasional clunk when I roll my driver or passenger windows down, but again, it's occasional.

And I also have a very soft whine (almost like nylon gears rubbing together) when I turn my steering wheel after the car has warmed up.

Front-end Clunk. Found You! They Fixed You!!
 

BLCKNED: Just returned from my Performance Ford Dealership with the TBS 07-18-2 upper strut mount assembly modification completed! They wrote the job ticket and replacement parts request on this Tuesday and two days later, All Done!! Glad to report that the front end is now as quite as a new Lexus! We test drove CalStang on rough roads, railroad track crossings and on a highway with expansion cracks too!! Wonderful! I love it!! Its All Good! When I arrived, they pulled CalStang right into the same shop where they work on the new Roush Stangs and put him up on the lift. The Shop manager said. "Don't worry about your Stang here in this shop". "We are all professional car guys and we understand!!" When I got back from lunch, they said that my GT/CS was all done. No charge and they thought I should be very pleased! So if you have this clunk noise too, just get it done. :nice:

Thanks RC, i plan to hit the dealer...my NEW dealer next week, its a pain to hear it cuz she sounds like she's falling apart, but I have no choice for now, cuz Ive been super swamped with work. But glad its an easy fix. My technician said that he would just go on a ride along with me to duplicate the sound, so maybe we can avoid this now and stop wasting time. Again, this is why I love these boards. Great help around every corner :metal:
