Ford F-150 (2004-2008) :: Anti-Lock Brake Slightly Kicking In For No Reason
Sep 2, 2011
Well I have a weird thing going on with the anti lock brakes. Its normally more noticeable when its cold. Coming to a slow stop you can feel the anti lock brakes pulsing slightly or more noticeably if you hit a bump braking at slow speed. The only mods to the truck are 285/70/17 inch tires and a leveling kit. Not sure whats going on with it, but i thought i should check here before getting my wallet lightened by the dealership.

I have a 2000 silverado. When I come to a stop, sometimes the anti-lock brakes will kick in. it makes that all too familiar grinding/clicking sound that I hear all winter. However, it is happening during the summer/fall. It doesn't happen every time I brake. It seems to happen most when I am coming to a stop on an uphill or downhill grade, or when I am stopping while turning. It doesn't happen the whole time while braking, just right at the end before the vehicle stops. It also seems to happen more frequently when it is warmer out. The tires don't skid while it is stopping either, which I guess is supposed to happen. It is a concern since it does take me a bit longer to stop when the anti-lock is going, and I never can predict when it will happen.

I have a '99 E350 van that I am feeling a light anti-lock brake pulse in the pedal when I am rolling to a slow stop under light braking. Braking doesn't seem to be affected, but it doesn't feel right. I tried locking up the brakes and didn't feel any anti-lock pulse...seems backwards.

I was driving my Dad's Camry in the rain and at one stop I heard what sounded like the anti-lock brake noise and vibration. Heard it again when stopping on leaves. Didn't think much of it until I started noticing the same noise when the road was dry and clear. All the stops were gradual, from under 30 mph. The car stops fine, less the noise. I hear the noise approx 1 stop of 3 or 4 regardless of road conditions or weather.
What's the cause? Since it relates to the braking system is this something I should have the shop look at asap? This is a 2005 but with under 60,000 miles. Has been well maintained.

I have an 04 f250 the 4wd won't lock in for some reason. The truck has manual locking hubs (turn them to the right to lock in 4wd or turn them to the left to unlock them) and I get the light on the dash just fine but the truck doesn't actually lock in.
When i I put it in 4 low it feels like it's in but it's not. I also noticed that when I put it in park while it's in 4 low it makes a crazy sound like it would when you put a car in park while you're still moving and the park pin makes that clicking noise.
Anywhere in particular I should start to look? Nothing up in the front end looks abnormal or out of place.
I've had the truck 10 years. Never had any 4wd related issues. I did however replace the transmission in December (and I did successfully use the 4wd after the transmission was installed).

I have a 2008 Elantra SE. The anti theft alarm gets triggered for no reason on occasion. At first I thought it was only on rainy days, but now it happens in full sun as well.
I don't need the alarm, as nobody pays attention to them anyway. Is there a fuse I can remove to disable it?

Truck has been taken care of, new Motorcraft plugs done 15,000 ago, never had any issues with truck until recently. Started bucking and kicking, threw CEL light, pulled codes. P0018, P0022, P0300, 305, 307 and 308. All of the misfires seem to be happening only on my left bank. I threw in a new camshaft position sensor just for the hell of it. This issue goes away and comes back intermittently. I drove it for a day and it did fine. Had power and then started it later to go home and it was misfiring, got to a stop light, cycled key and everything went back to normal. 2007 Ford F150 Lariat 5.4l Triton....116,000k....

I just got an 08 F-150. No key fob and no power locks but it does have what appears to be an anti-theft device that blinks on the top of the dash. I would like to have keyless entry. What steps should I take?

I have a 2007 F-150 FX2 and as of 8-10 months ago I started having the security alarm go off for no reason. I thought maybe I sat on the fob or something stupid but it is getting to be more often. The truck sat at the dealership for 2 days last week and nothing. They decided after lightly bumping the grille and it went off the sensitivity was too low so adjusted that up to a reasonable bump required. Well it went off last night at 1:30 AM, so I don't know what to do now. The service writer did say he had seen this and it was always a door sensor but having 4 doors which one??

My 2000 Ford Ranger 4x4 truck's anti-lock braking system is not working properly. When I slow down for a stop my anti-lock brakes kick in every time for about 1 or 2 seconds. What can I do to stop this from happening.

I have a 2007 an at about 52mph the truck has a slight but irritating bounce (up an down) an after a while sickening. It maybe felt it was coming from the rear. So I had the rear tires balanced an the guy said my right rear tire had a bend to it. Well assuming that the balancing fixed the problem it did not. So I'm going to put on the spare to see if it still bounces what else should I do?

I have a 2011 F350, with a 4 inch Rancho Suspension lift. Ever since the lift kit was installed, more commonly when turning to the left than right, the anti lock brakes come on and the traction control light comes on/flashes. without even stepping on brake pedal.
It seems to happen when the wheel is at about 80% of max turning, about 15mph. Both wheel hubs and sensors have been replaced. road tested with Ford tech , he watched the speed sensor input while hooked to the computer and all sensor are reading correctly.
Today I went in a constant circle and can make it do it non stop, and when you try to press the brake pedal while the anti-lock (grinding/chattering) noise is happening, it only gets louder.

Recently when I leave my driveway which only has a slight grade to it my truck makes a clunking sound when I hit the gutter and while turning slightly. Also my front drive line from transfer case to front axle has some play in it. I can rotate the front drive line about 3/4" to an 1" while parked in the driveway. Changing u joints. I figured this would be a good starting point. 2005 XLT 4x4 5.4L F150.

I bought a '05 F-150 with a 5.4 with 112k miles on it a few months ago. It had been sold from an auction, looked really clean, and a good price. Not long afterward it started having issues with running rough at idle. That's when I found this forum and began reading. Tried different things but it only got worse and finally had a shop look at it. Cam phasers were not doing well. Not a cheap fix but more involved engine work than I had ever done so I had them do the work.
It ran fine for a few days and then the idle rumble came back slightly and the check engine light (CEL) came on. I read the code and it came back with a number that indicated air flow was an issue. Internet search said to clean the throttle body. Some threads on this site also said do the Mass Air Flow (MAF) sensor while I was at it. Much has changed since I used to work on cars as a kid. Everything has it own cleaner. I cleaned the MAF sensor with MAF cleaner. Cleaned the throttle body with throttle body cleaner (it was beyond filthy) and a toothbrush. Put it all back together (started late and it was dark by now) and took it for a quick run to see how it had improved. Instead of smooth, it started running even rougher, and within 100 yards went into fail safe mode. Now my mood is getting darker. Park it and go inside to watch the Aggies in their bowl game.
Good game but the truck is still running rough and I am losing confidence in my ability to do simpler things on it. I get up the next day and run codes on it. It had three codes all pertaining to air flow or the throttle position. I am thinking I screwed up the throttle setting somehow when cleaning or maybe only put the MAF sensor in upside down (that seemed unlikely since the screws only seemed to line up in one orientation). So I open the hood to check the MAF sensor just in case and find to my embarrassment that, in the dark, I failed to plug the MAF sensor back in. The problem was a loose screw holding the tools. I plug the sensor cable onto the sensor and take it for a ride. It runs great. Life is good. MPG is climbing higher on the onboard display. My confidence is returning even after humbling mistakes. After everything, I still love this truck.
So, now for the tune-up advice. The truck runs well but still rumbles slightly. Based upon everything, I believe it was well cleaned before it sold but maybe not fully serviced. Spark plugs were possibly never done. I intend to do a tune-up on it but do not know what has already been done so I'll assume almost nothing. The air filter looks brand new. The serpentine belt has nicks so that will be on the list. I am thinking of changing the following:
Spark plugs
Spark plug boots
fuel filter
serpentine belt
PCV valve
Oil was changed when the cam phaser work was done. So the advice really boils down to a question:
Is there anything else I should consider changing or doing or cleaning? I have not worked on cars much in the last 30 years but am beginning to enjoy it again.

Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.
It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.

I noticed a slightly rough ride around 70-80 mph sometimes on interstate a month back but thought it was my scalloped tires that need replacing and ignored it. Last weekend i had to go to MI from GA pulling a small enclosed tandem axle trailer (6x12). I started after work and made it to VA before stopping for the night with no problems not even at 70-80. Fueled up first thing in the morning (BP Fuel) and headed farther into the mountains when the truck started shaking when it should be downshifting (into overdrive I am guessing?)
No check engine light come on so i pulled off the road checked rear end and motor oil everything was fine, topped off tranny which was slightly low but was on dipstick .I let the truck cool for 20 min then got back going again. I continued driving with overdrive off, and not on the truck. Every time it had to downshift under hill climb it would start shaking but i would let out of the gas and it would stop. Once i got out of the mountains it was fine and couldnt tell it was running bad at low rpms, and also drove fine when i got off the interstate for fuel driving in towns.
I drove that whole day through ohio mich and back trough ohio when entering kentucky. It started to downshift and run at high rpms with no problem, and started acting up when i got back into the mountains.When the truck would go to downshift it started to shake uncontrollably again. then is when the check engine light come on and flashed. I babied in until tenn when i stopped at oriellys to hook up to scanner. scanner read misfire on 5 and ignition coil d primary secondary circuit malfunction. I checked the #5 plug (fine) and replaced the #4 coil, and didn't check the #4 plug.
t kept going and it never fixed the problem. stopped and jumped my coils around and check a few more plugs which all were fine but never that #4 (why idk), after being fed up, sat night, no mechanics around and wanting to get home i drove it the rest of the way. it never idled rough until i got almost home in Ga. When i got home the next day i pulled all plugs and all looked brand new still except the #4 which had the whole prong and tip completely burnt off. I replaced it and nothing changed, but my exhaust sounded restricted. Brought to a shop and it is now reading a misfire on 4 (with brand new plug) 5 7 and 8 and also saying it is running lean. They changed fuel filter and plugs but nothing still.

Problem #2 the anti lock lite stays on in the cluster, and just yesterday the service engine soon lite is now on, my truck is a 1999 F250 7.3 6speed manual with 77000 miles on it ...

When driving my 2006 F150 it drives real smooth until I hit 50, then it feels like I'm driving on a slightly bumpy road, once I hit 55, smooths out again. Only drives strange at 50 mph. Other speeds smooth as glass.

2006 F150 FX4 5.4L, 118k miles... At highway speeds (45-50) and (55-60) as I am slightly accelerating it feels like the transmission or maybe ignition system is skipping a beat. Kind of feels like a small bump. I replaced spark plugs with motocraft about 35K miles ago and recently all transmission fluid via cooler line. Had some concerns about system flush so I just drained and refilled entire system via cooler lines. I have read that it could be my COP's ...
