Ford F-150 (2009-2014) :: 2010 - Clunk / Lag On Takeoff From A Dead Stop Only
Feb 17, 2012
2010 F150 XLT FX4 5.4L Crew Cab Medium box, nice blue truck, lacking on chrome though.
My friend has a clunk/lag on take off from a dead stop only. Drives fine down the road, but when taking off from a complete stop, you step on the gas, and nothing happens for a second, feels like it lags, then clunks, gives a jerk, and takes off.
From talking to other newer Ford owners, seems like a common problem.

I have a 2009 f 150 two wheel drive and after reading and doing a little research I found my problem. Slip yoke same as alot of guys here,come to a stop clunk,take off clunk. My question is my warranty ran out,I had a 30,000 or three year and now I have 31,000 plus it's like the truck new when the warranty ran out. There is a TSB on it,10-22-6 NOV 10 Drivetrain - Driveshaft Slip/Bump On Accel. Or Braking... Will they do any thing for me,and how much would it cost me to have the work done at a shop.

There is a TSB on it 10-22-6 NOV 10 Drivetrain - Driveshaft Slip/Bump On Accel. I am going to pull the rear driveshaft and put in new grease MERCURY MARINE GREASE with TEFLON (2-4-c ) part nbr 92-802863A . How much do I need, will 8 ounces be enough.

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.

Well it's been 300 miles since Ford applied their "special grease" and put on clamps to eliminate the clunk when slowing and the slipping feeling at take off. Now the clunk is back. Every time at 25 it downshifts and clunks, then once again at 10. Drives me nuts. My service advisor wants me to "log" these visits so we can be more aggressive with Ford to get this resolved. I love the truck, but this is annoying driveline slop. Almost like the splines weren't cut right and Ford is using heavy grease to fill the gaps......developing...

Slight clunk feeling from dead stop under more aggressive acceleration...my 14 250 AWD has done this on 3 or 4 occasions.

I am changing the front and rear axle fluids on my '10 f150.The rear was no problem,the front is my issue.I took all the bolts off and loosened the cover to drain the fluid but it is a tight space and cannot take it off completely to clean it up and put on the gasket sealer.

I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.

I've had my truck start making a nice CLUNK from the vicinity of the rear axle when starting moving from a standstill. (and it's a pretty decent thunk sometimes, you hear it AND feel it). I called and made an appt to bring it in and have it checked out (also having the first oil change done and gonna see if they can figure out why the automatic headlights are almost always on even on a bright sunny day) ...

Intermittent chirping noise when accelerating from a stop. It sounds like a brake chirp but it comes and goes. Not brakes. Changed pads and turned rotors chirp is still there.

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 2009 F150 4x4, XLT crew 6.5' bed, 5.4 engine. The truck has a very strange erratic throttle behavior from a dead stop through low speeds, shifting seems very strange at low speeds too.
Dealer tried re-flashing the computer, but that didn't fix it. They talk about some valve that sounds to me like it's similar to an EGR function, but I cant remember what he called this valve. He explained the issue as exhaust gasses that are to be recirculated and burned, but the valve is opening at the wrong time, or stuck open or something so it feeds the fire so to speak.
Does any of this sound typical or common? Is this something that's hopefully easier to do than a spark plug change on a 5.4?

Towing with my 07 F150. I now have a noise all of a sudden. I worry that is the rear end going out. As I accelerate normal from a stop, I , for one feel bump-clunk sensation, as if I have a bad u joint. 2nd I now have a "whip whip whip" whirring sound, sound character speeds up as I speed up.
I hope the sound is the brakes, because I know they are getting down to the end of their life.

I have purchased number 4024, in CW, and I am posting to ask about the transmission. During take off from a dead stop, the car tends to jitter. Not a fast repetitive jitter, more like a slow, stalling out feeling. a go stop go stop go stop go that blends in to each perspective motion. Now when I purchased the car, it had already been modified by member CWR32. The mods included GIAC software, intake, exhaust as well as suspension, bar, skid plate and all of that good jazz.
What I am trying to figure out is if any of your cars do or has done the same, either stock or modified. I have read something stating that the software controlling transmissions such as DSG determines how smooth the transition of gears will be. Is it possible that the tranny software was upgraded, is this tranny REALLY that clunky, does yours tend to do the same.
There is also a slight tendency for the car to jar roughly when put into reverse or first if i let off the brake quickly.

I am looking at a 2010 f150 4x4 lariat that shifts and drives great a thru all gears and down the highway. The truck makes a clunk whenever you start to move from a dead stop ? go about 5 feet and it runs great? my 07 fx4 has 247,000 miles and still doesn't make any noises, the 10 has 75,000 miles on it ford maintenance oil changes and trans flush, am going to have mech look at it, anyone think of possible items to zero in on? it has the 6 1/2 ft bed with 2 pc driveshaft ...

I can only get the left front speaker in my 2010 F150 Lariat to work. I've played with the L/R balance and B/F fade.

I have a 2001 Subaru outback. Recently I've noticed a rattle when I accelerate, especially when I take off from a dead stop. I sounds like it's coming from the front wheel area. It also occurs sometimes when making a turn and then accelerate. It almost sounds like an object in a box and someone is shaking the box-very noticeable.

Been suffering some take off shudder as well as the 55mph shudder and finally took the truck into the dealer who informed me it is throwing a couple of misfire codes (no CEL). Quoted for spark plugs. Looking around the boards, seems a lot of people are seeing premature wear on the ecoboost plugs and have had success regapping or replacing. Any words from 5.0L owners? What are the odds they just need regapped? I'll probably just replace them anyway, but its a good discussion. Also are they are simple to replace as it looks- just pop the coil packs off and they are there in the valve covers?

I have a 2002 F-250 7.3 Powerstroke 4x4. My truck has developed a "clunk" for lack of a better term when accelerating from a dead stop. It is not a shudder as it only happens once within a few seconds of depressing the accelerator and then goes away until the next time I stop moving.
It feels like either something in the drivetrain is not engaging right away, or something is releasing, like a stuck caliper or something. From the way it feels and what I've read so far about the TC/Trans, I'm assuming it is something worn in the drive-shaft/rear diff.
But it needs brakes badly (already have all new rotors & pads ready to install) so maybe a caliper is sticking when depressed and then popping loose under initial acceleration? I think this is unlikely but possible.

I have a 2010 F150 Xlt super crew with a 4.6L. I've noticed lately when I start from a full stop the the truck has a small shutter or hesitation before it starts accelerating. Its barely noticable but it is there. What it could be? I had the tourque converter replaced just before my warranty was up, I've only put 30000 Km on it since. Was wondering if it could be the cause.

My 2012 F150 has developed an odd issue.... It doesn't seem to want to always take off in first gear. I've had it happen several times where the truck would take off in a high gear but yesterday was the worst yet....I was towing my boat and the truck attempted to take off in 5th gear....I threw it in neutral and back in drive and it was fine, what's causing it.
