Ford F-150 - 1997-2003 :: Speedometer Is Not Completely Dead But Bounces Around
Apr 17, 2012
1997 F-150 XLT Extended cab. 4.6L VIN 6, 5 speed manual, 4x4. Replaced speed sensor on transfer case, speedometer is not completely dead but bounces around. Seems to be about 10 mph below actual speed. When I come to a stop say at a red light speedometer drops to zero at about 20 mph or so. Cruise also inop. It seems like whenever I let off the gas to stop or shift gears the speedometer drops down but then goes back up but not to the right speed. It has the mechanical odometer by the way. Everything else seems to be working fine. New speed sensor did not come with the plastic gear so I had to reuse the old one. Not sure if that gear was bad or not, but it was the pink one if that matters.

I reprogrammed my computer, to get rid of a bad tune with the Ford Program. After reprogramming, and entering in my tire size/gear size my speedometer and odometer no longer work. Also my overdrive light is flashing. Does this truck have a PSOM and could that be bad? What else could cause the problem, it definitely happened when it was flashed. Whats the cheapest way to fix it?

I thought my brakes were sticking........don't think thats the issue. My rear end bounces....you can see it, and its only certain times...mostly when its hot, or I've been driving for a while (an hour maybe)
I have been taking notes on the symptoms, and finally got some noise today. When the rear end starts to hop it sounds like you are riding on rims and it will actually slow the truck down if you let off the gas.
The brakes aren't hot beyond reason, and I've noticed that it occurs mostly after making a sharp turn???? Or a fast medium turn such as a quick merge.
I think something is either coming loose in the rear or ?????? Not sure Also, when I pull my camper I haven't had it happen yet.......may be a coincidence.....? Or the fact that I take turns slower when its attached.

1999 4.6 F150. So my truck is 2wd, and I have noticed that after about an hour of driving, and regular braking at turns and stop lights that between 25 and 55mph my rear end bounces like I am riding on speed humps. Not subtle at all. You can look in the rear view mirror and see the bed going up and down about 2". Feels like it has square tires if you know what I mean.
Anyway, I checked the rear brakes thinking maybe they are old and starting to stick. I have never smelled any brake burning, but I can only assume its the brakes because in that same hour the rear brakes develop an uneven feeling. I am sure you know what I'm talking about......when your brakes go bad you have that on/off brake feeling. Like surging I guess.
They are drums by the way. The shoes themselves don't look bad.....there is still meat on them. Maybe about an 1/8". No rivets showing or anything. The passenger rear shoe has one hairline crack at the top, but no other signs of damage.
Lastly, I checked the rear end and I wasn't sure what the margin of acceptable play is for in and out movement of the rear wheels. If I grab my tire I can push in and pull out with about an 1/8" of play......normal????

2003 f150 5.4, 4x4 ... Truck is shaking pretty bad, idle bounces between 500 and 750, and its throwing p0172 (rich on bank 1), P0174 (lean on bank 2), and it looks like a misfire on cylinder 8 judging by that power graphy thingy. I'm going to check for a vacuum leak tomorrow on the PCV.

I have an 04 5.4L SCREW Erratic Speedometer.
Most of the time it works, some of the time it bounces or doesn't read at all.

I think my E4OD in my 95 f150 is slipping in 4th gear. Just started the last couple of days, the engine rpms stay steady but the speedometer bounces around 3 to 5 mph. Thinking rebuild of the trans....

So I have an 03' Camry le 4 cyl. And it has been having a hard time starting for a while. Finally it completely died. I tried to jump it but accidentally hooked up the jumper cable on the other car backwards. The car then wouldn't even try to start, found and replaced the alt fuse in the engine compartment (what a pita), so I jumped it correctly and it started, but would not move when shifted Into drive or reverse. When in gear pushing the gas pedal does nothing, no rpms at all.

I have an 03 f150 5.4, it runs fine, shifts fine and will get up to speed. I can go over 40 but the speedo will only work until i get to 40 and then it just stays there. My rpm guage seems to be working fine. I thought it might be the speed sensor/output sensor on the trans but it shifts fine so I dunno anymore?

I have a 2001 ford f150 with a 4.6 liter v8, my ac compressor is completely seized up, I can't afford to replace the ac right now. So I would like to just get a shorter serpentine belt to bypass the ac for now, need to get a measurement on the shorter belt for my engine? and the proper way to re route the belt without the ac?

My 1997 f150 when I put her in drive the speedometer goes up to aproxx 36 mph and stays there no matter what I do or how fast I drive and then slowly falls back to zero when I shut the truck down. Where can I start, I had someone look at it years ago and the said the cluster was bad. I use my GPS to tell me the speed I am going, everything else works in the cluster.

I have a 1999 F150 Supercab, 2wd. I just replaced the front rotors, calipers, and pads. Before I did this, the front right caliper was locking up completely. Now, after the new stuff is installed, the truck pulls very hard to the left when braking. The harder you brake, the harder it pulls left. What should I look at next?

2003 F150 4wd with auto climate control. My blower for heat and AC completely stopped working a few weeks ago. I have checked all fuses, i replaced the relay under the dash, i replaced the blower motor control module. I supplied power to the blower motor itself and it ran fine with no noises. I ran the self test on the controller in the dash under the radio and it passed. I am not sure what else to try.

So I had the same , "noise" in the rear of my truck that i see other people having, at first I thought it was my tires, since I ran buckshots, so I switched over to street tires, and low and behold it sounded like I had buckshots still on the truck. So this thursday I pulled the diff cover off, and guess what i found!
The abs ring on the ring gear, was completely off , and the bolt that holds the pin for the spider gears was broken with just about maybe 3/8 to 5/16 of an inch left in the pin, right now i am still working on how to get that out of there.
also found a 1999 ford f150 2wd truck, 4.6 auto , that someone pulled a 1997 4.6 engine out of and put it in this truck and now it won't charge, and i think it's cause of the pcm needing to be reflashed. tested the alt, battery, everything is good, i just don't know if the pcm controls the charging system.
Pics will come soon of the differential destruction.

My speedometer has not been working for months now and it really hasn't bothered me as I go by RPMs, but I am going to make a long trip in a few weeks and I wanted to try to get this fixed.
The speedometer flips over to 100 mph and rest on the opposite side as it should. When I accelerate it does not move until I get over about 35 mph where it will then flip to 86 mph. It will slowly move to 82 mph as I accelerate up until 75, where it will then no longer change. Every once in a while it will start working when I start the truck up, or when I am driving down the road. It has before, within a 30 minute time frame, started working and stopped working 6 times. Currently my ABS light is on, but it has been on long before this started occurring. Every other gauge on my dash works.
I drive a 5 speed manual V6 2003 Ford F150.

On my 01' the bottoms of the bump stops are completely gone. Rusted out to the point to where the rubber stop on the front lower control arm (if the truck bottomed-out) would go right thought it. The rubber stops are fine.
This pic was taken from below the control arm looking up. You see the rubber bumper and just above it is the stop (some what triangular shaped). the bottom is rotted away... Are these replaceable or repairable? They seem like they are welded to the frame.

I just got a 2001 f150 supercrew 4x4. Speedometer started cutting in and out. Just the speedo needle cuts in and is accurate for a long while then jumps up 10mph then goes back to accurate speed then cuts out and needle goes to zero for a bit then comes back on to accurate speed.
Just the speedo needle is the problem the trip meter and odometer and all other gauges on the cluster works just fine. Do I need a new cluster? Wouldn't be a speed sensor? Speed sensor would just cut off and would affect the odometer too wouldn't it?

I recently purchased a 2000 F150 Regular Cab Work Series with the 4.2 V6 4x4 and an automatic transmission. It has what seems to be an electrical issue where the speedometer and gauges come in and out seemingly at random. All of my fuses are good with the exception of Fuse 1 in the fuse box under the steering wheel, which will blow every time I put a new one in. It seems like there is a short in the wiring for the radio? However Fuse 1 is supposed to control only the audio, and I'm not sure why that would be an issue with the gauges.
When they come on, everything seems to work just fine. Also, even when they go out and I have the headlights on, both the gauges and the car stereo will be backlit with the green glow.
When I turn put the key in the run position, the gauges will come on and remain on for a random amount of time after I start the engine, then will go out and come on at random. When the gauges go out so will my check engine light (code P0460).
