Ford F-150 (2004-2008) :: Engine Knock / Clunking Noise When Come To A Stop Or Takeoff Or Steering
Apr 29, 2012
I am having a hard time locating a mechanical knock coming from my truck. This is not an engine knock but rather a clunking noise when I come to a slightly abrupt stop and sometimes when I take off or am steering. I have recently replaced my upper and lower ball joints and all the u-joints as well. My truck has a 6" Fabtech Coil over lift and a 3" body lift. The truck is also rather squeaky when going over speed bumps.

As I said when I take off from a dead stop I can feel a clunk or a bump that feels like it is coming from the rear wheels. I can feel it more than I can hear it, although I can hear it a little. It is difficult to describe this. It is only for a second and kinda feels like the rear wheels have no traction then it bumps and takes off. If I ease into the accelerator I can avoid it, but I don't have to hit it real hard at all to get it to do it. I am sure it is not u-joints as I put a brand new drive shaft from driveshaft specialist on in the spring.

Knock or tick at 1000 rpm. Truck has 20000 miles on it. Dealer replaced cam phasers. What next?

My 06 FX4 has 106k it started acting up shifting last week and its driving me crazy not knowing what part to change. Sometimes when I take off slowly from a dead stop it shifts really quickly into o/d by the time I am at 15-20mph. Doesn't matter far as hot/cold but if i accelerate quickly it doesn't seem to do it. I have read it could be the Shift solenoid or TPS.

I have a clunking sound coming from the rear of my X when I stop and take off. The sound does not happen until the vehicle has been driven for a few miles. After it has been driven, I will get one clunk when I stop. When I take off I will get one clunk as the vehicle starts to accelerate, and another clunk as I give it a little more gas. What could be the cause of this? I do not get the sound when I shift from park to drive, or drive to reverse.

My outback has 57k miles on it and already needs the front struts and rack replaced (diagnosed today at the Subaru dealership). The car has been making a whining noise in the engine and has been clunking when making turns for the past week. I have also noticed it hasn't been taking bumps as smoothly. They told me that both ends of the rack are leaking and both front struts are leaking. My husband did admit to hitting the curb on the driver side front tire pretty hard while making a u-turn about a month ago, but all other driving is pretty standard. Yes, we drive on dirt roads in the mountains a few times a year for hiking, but don't drive in a manner that I consider wrong. Did the u-turn incident cause this? (hard to believe that would affect both sides of the rack and struts).

I've been living with a mild "clunk" or "bump" in the drive train when I would first begin to accelerate from a full complete stop. It would only happen after a complete stop. It almost felt like it could be normal, but it seemed to be getting worse over time.
At first I thought it was my transmission...but after some internet searching I found some threads talking about the slip yoke on the drive shaft being the cause. In that the slip yoke needs to be pulled apart and re-lubed.
Anyway, I thought I'd post and let eveyone know that after pulling the slip yoke and re-lubing with grease my issue is solved! The "clunk" is totally gone. 100% Smooth now. If has this issue I'd highly recommend re-lubing the slip yoke.

On my 2004 F-150 SuperCrew, all I needed to do was remove the drive shaft at the rear differential (4 bolts, use 12mm 12 point socket or wrench). Then remove the FRONT clamp on the slip yoke boot. Then slide out the rear 1/2 of the drive shaft. Be sure to mark the drive shaft orientation with the rear differential flange and the slip yoke before you remove the drive shaft to ensure you put it back together correctly.
Re-lube the slip yoke, then slide it back together and reinstall the four bolts at the rear differential. Torque spec is 76 ft-lbs. I used Valvoline FORD-LINCOLN-MERCURY moly grease that I purchased at my local AutoZone. You'll also need to install a new band clamp around the rubber slip yoke boot. I got mine from AutoZone.
Here are some links I found with pictures showing how to do this. Both procedures below are on SuperDuties but its basically the same procedure. Just follow my specific details above for the 2004-2008 F-150

I recently bought a 2005 F150 King Ranch. I had a 900km drive to get it home but only mad it half way and am now stuck. I was stalling every time I came to a stop and eventually lost oil pressure. This is when I stopped driving and took it in. The shop said it had a knock in the lower end and stopped diagnosing it there. I can now sell it for parts and take a big hit or I can try and patch it myself.
I am assuming based on my symptoms it is a spun rod/main/thrust bearing. The mechanic was not very supportive to narrow it down to anything other than replace the motor.
How many km might I get out of this engine if I pull the motor and replace only the crank and rod/main/thrust bearings. This will not be my daily driver so if I can get another 50000-100000 km off of that, then it will last me at least 5 years.
This is of course assuming that when pull it apart I do not find an other major problems such as bent or broken pistons and rods or scoured cylinder walls. I am not that experienced of a mechanic, so I am not that confident about pulling the heads off and rebuilding the whole thing.

Bought an 05 FX4 SuperCab in May - been in shop twice for a "clunking" sound when accelerating from a dead stop. Dealer says it's "operating as intended" and that no damage was being if I continue to drive. I thought it was a rear problem with the limited slip. Dealer says it's the tranny and that Ford is looking into the problem (apparently quite a few are coming back). She runs smooth and shifts fine once she gets going. Just starting from a complete stop feels painfully wrong.

My Dodge van makes a jerking/clunking knock under the vehicle when it comes to almost a complete stop. Feel strong inside the vehicle. If I break hard or gently that jerking/clunking knock will not happen- gotta hit and miss when I tried to control it.I am thinking of front brake which I must replace, it's pulsation occasionally....

A 2004 and up f150. I found one in great shape for 5,000 dollars with 120,000. Drives good but it has a knock I'n the 5.4 engine. It gets quieter when the engine is warm. Should I avoid this truck or will I be okay with purchasing? Only thing holding me back from buying truck is the knock...

I have a 2008 fx4 with 75000 km it runs great but when I go on a long ride up hills or tow my trailer it acts up only when I get to my destination. the engine will run really rough and knock loudly seems only when I use reverse or sometimes park (and oil pressure in dash looks good),and if I shut ignition off and restart it no problems till I make engine work hard again.

I've read alot of info about the 4WD system on the F150's, and I'm having trouble diagnosing what might be going on with mine.
When I put my truck in 4HI (or 4LO), I get a popping sound that seems to come from the front middle/front drivers side when going at speeds around 20-25 and over. I don't experience any loss in traction (that I can tell) or power, but the popping is very loud and noticeable (passengers can hear it clearly).
My problem is a little different than most, as their issues with popping seem to happen when they are not in 4WD, where mine is only when in 4WD. I replaced the IWE solenoid today (wanted to anyway to get the updated casing/shroud) and the problem stayed. I also disconnected the vacuum lines at the solenoid and drove - no noise. I then kicked in 4WD on the switch, and the noise started, which leads me to think it is not vacuum related.
I am kind of lost as to what may be going on. I would think something where teeth broke, etc. would make noise all the time in 4WD, not intermittently or at certain speeds. The noise sounds almost like popcorn popping. I went up the same hill about a dozen times today, and it happened maybe 5-6 times. I don't hear it often (if at all) with speeds below 20 MPH. I can switch in and out of 2WD, 4HI, and 4LO all day with no issues, as well.
The only modifications to the front end have been a 2.5 inch leveling kit, and the only other issues I notice in the front end is a shaking when on the highway, that seems to go away after a while of driving at the same speed. I recently had a front end alignment, and the only thing the tech mentioned was that I will need ball joints in the next 6-8 months (but he said they weren't bad).

I have a 2006 F150 FX4 and after having the 4x4 go out and replaced the front right IWE have fixed the 4x4 but still hearing a clunking noise.
The clunking noise started after the 4x4 went out and was really bad for awhile and then went away and has now come back really bad. It sounds like its coming from the front driver's side wheel area and clunks as fast as the wheel turns.(faster = more clunks).
I'm very new to mechanic stuff but enjoy learning and fixing things myself.

I have a 2004 2WD supercab. And am hearing a 'clunking' sound when I turn almost full-lock. Below is a summary of what I have experienced so far:
- My truck used to be lowered 2" (below stock) at the front since new. Last month I lifted it (front and rear) and it now sits 2" above stock on new rancho shocks.
- I installed a camber kit and had the front aligned (toe and camber) after the above suspension work.
- The truck drove beautifully for two weeks until one day a 'clunking' sound was heard from the front-left every time I turned left. The alignment also changed as I had to now hold the steering very slightly to the left to drive straight.
- The alignment shop re-did the toe tracking (the camber did not change) and the truck drove great for about a day. Now I can hear the same clunking sound when I turn right and the tracking is again screwed up meaning I need to hold the steering very slightly to the right to drive straight.
What parts are playing up and what may need replacing?

For the last few weeks (about a month) I have been experiencing a clunking noise/ knock on acceleration coming from either in front of my feet or below my feet (drivers side) ONLY on acceleration and only then from a full stop. I can also feel the clunk as well which leads me to believe it is a transmission mount.....maybe an engine mount. I am taking her to the dealer after work today. we had some very cold weather and I was hoping it was just ice but yesterday and today were well above zero and it is still there and it is EVERY time I accelerate. Which is a somewhat good thing since I will be able to replicate the problem for Hyundai.....

So for the past few months I have been hearing a knock sound when taking off from a stop. It does it every time, and its loud enough to hear distinctly. It sounds like it is coming from underneath the cab, maybe the trans or rear engine area. I thought maybe a mount. It only does it when taking off from a stop it does not do it while driving. Where to start. I hope it isn't serious, at this point it is more annoying than anything else.

I am getting 14MPG out of my 2007 with a 4.2L 5 speed manual single cab. That seems pretty low to me considering the HWY MPG is rated at 19mpg.
My son and I have also noticed when taking off from a stop it is very easy to kill the engine, it seems to happen more so in Reverse but does it a lot going forward. I have driven many stick shifts and this one is by far the worst as far as it dying on take off, really I have never seen one this bad.
I have also noticed some spark knocking at HWY speeds and it also feels like it has a miss a idle but when you push the gas it runs fine.
Installed Motorcraft Platinum plugs a few months back and checked all the gaps. Also new orielly brand plug wires at the same time.
