Ford Super Duty (1999-2016) :: Suspension Is Too Stiff To Push Down / Shudder At Freeway Speeds
May 31, 2015
I have a 2006 F250 Lariat CC FX4. I bought the truck with 68,000 miles about 3 months ago. This is my first 4WD and I'm wondering if I need shocks.
I know how to check on a car but this suspension is too stiff to push down a corner so how do you test? Or do you just go by the age? At freeway speeds when I hit a bump I get a bit of a shudder that makes me wonder if the axle is hopping.
If I were to replace them are the Rancho shocks OK for a replacement? I will spend very little time off road and mostly use this truck for boat towing and hope to buy a travel trailer down the road.

My 01 f-250 4x4 diesel has some steering wander Ive been fighting for a while. It feels like the front end is stiff and not returning right. All four spindle ball joints were replaced in the last year and a half. The tie rod ends seem to spin easily enough with a wrench but are not loose. MY question is how hard should it be to rotate the spindles with no tires or tie rods on them, wondering if my newer ball joints are too stiff and causing the wander or if everything checks out it my alignment being a little off would cause poor return?

On a 2003 5.4 f-250 XLT 4 door, long bed
Running 285 tires, none lifted, factory lifted for snow plowing? Did have a plow mount when purchased used.
Had the truck over a year now & love it. My only real dislike is the stiff/ rough ride when empty, which is 80-90% of the time for me.
I know my truck & year have leaf springs with shock dampeners on the front, vs the coil spring and shock dampeners that came in the later years for a much improved ride. Also my struts are "Rough Country" which from what I understand are cheaper shocks. Had a 04 Tacoma I replaced with Bilstein 5100 shocks after leveling it & it was an amazing difference. So that's my only real comparison in shocks. I've read of guys replacing their entire front end for the coils & springs. Not interested in going that deep into it for a better ride. If that's my only option, all be happy with the ride as is.
What are my options if any? Better shocks/struts? Other than my rough country that are on the truck? Purchased used a year back & never felt the "stock struts".
I did find Bilstein 5160' s for my model truck. Link : [URL] .....

I've got a 2000 F250, 5.4L 4x4 with the ZF5 5-speed transmission. Three years ago I replaced the complete clutch assembly, pressure plate, throw-out bearing, etc, and had the flywheel re-machined. Put it back in and all has been well. Only has about 15k miles on it. Earlier this week I went to drive it and all of the sudden it started getting harder to shift and by the end of the trip the clutch will not disengage at all when I push the pedal in.
Furthermore the pedal is much harder to push than it always has been. Checked the reservoir and it's fine. After some searching it seems to most likely be an issue with the master and/or slave cylinder either needing to be bled or replaced. Further reading revealed that bleeding and recommends just replacing the whole system, so I've priced that out. Was it a master/slave issue? Anything else I should check in case it isn't?

I got a 2011 250 SD 6.2, I have what feels like a catch in the steering, on center, when you turn the wheel feels like it just gives and stay's there, either way you turn, Checked front end, ball joints tie rods etc., the hubs are unlocked, feels like when the u-joint on the steering shaft goes bad and you get that bind. But this truck doesn't have them anymore, just a rag joint at the box. It only binds at center, and wont return, took steering stabilizer off and road tested same thing, air in tires good all the way around, has about 58,000 miles on it.

My steering got real "heavy" almost as if I had no power steering so I replaced the power steering pump. The steering got a little easier but is still very stiff. It's extremely hard to turn at low speed just off idle...I have to rev the engine a bit to get it to turn.This is on my 1999 7.3 f350...I've ran 33" and 35" tires on it it's whole life and this is the first PS pump I've replaced since 1999...never replaced the steering box.

I have a 2001 F250 SD V10 and when at a dead stop and with the brakes applied, steering becomes very stiff and almost impossible to turn the wheels. If I let off of the brakes and move a little the steering is just fine. I hate like hell to spend the money on a new power steering pump if it isn't going to fix the problem. Simply put, deap stop, brakes on, wheels don't want to steer. How do I fix it?

I just replaced the ball joints on my 99 F250 SD 4x4. Driver side was a bit stiff to turn the knuckle. Passenger side is very hard to turn. The upper stud wanted to turn in the sleeve after torquing to spec. I had to lean on it to lock it into place. I have to check today to see if parts store is open to get a new set. The brand name is "Drive Works". I have installed ball joints in this vehicle previously, and in another Ford truck with the same style. I have the proper tools to do the job. I have to determine if both joints are tight or just the upper. I won't buy the same brand again.

2006 F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trans sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop diagnostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

I have a 14 F250 Superduty with 6k miles, it has started a shudder around 40-45. It only does it briefly if I let off the gas and then accelerate it goes away.

2002 Ford F-250 5.4l ... What is the difference in sound between a lifter tick and an exhaust leak? I have a ticking noise, almost sounds more like a puff of air noise, it only makes the noise when I push the accelerator and is coming from the right side. Noise is most noticeable if I put my head under the passenger side front fender. I am guessing I have an exhaust leak somewhere between the heads at cat but just wondering about the difference in sound. I'd think if it were the lifters they would tick at idle, right? The truck sounds great at idle (after doing a tune up) I just want to get rid of this annoying tick when I accelerate.

I have a 2010 F250 extend cab 4x4. While traveling about 70 down the freeway I get a whistling noise. It is usually worse when the wind is blowing hard or behind a semi. Wind makes the noise louder so I assume the noise is coming from the air hitting something. Slow down to 50 and noise goes away. Do not think it is mechanical because when a gust hits the truck it is worse. Checked all the windows, windshield and rubber parts. Where I should look.

I just broke my 2000 F350 7.3L 4X4. I never had any shift problems in the 3+ years I've had this truck. 3 days ago, I stood on it to enter the freeway, it dropped into passing gear, then a loud THUNK, a shudder, and no gears whatsoever. I coasted to a stop, checked to make sure the transfer case hadn't jumped to neutral, ran the tranny through all gears, and nothing, truck wouldn't move.
I took the tranny pan off this morning and its clean, just a little fuzzy on the magnet but nothing more than normal for 3 years and 200k miles without service. At this point, I'm thinking its the torque converter let go and won't pump fluid. Tranny Shops only want to sell you the whole assembly, not fix the problem.

My truck seems to shudder between 40 and 60 mph when it's in OD. If I turn off OD it seems to go away with the increased rpm's. Although I can't be sure if it genuinely disappears or if I just don't notice since I'm at 2100 rpms instead of 1500. Trans fluid is clean. Is this a common problem in these trucks? Just filled up from flat E the same day air temps about 4 deg. Truck was fully warmed up. Does this sound ignition related, tranny or fuel related?

Driving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.

My question is this...when my foot makes contact with the brake pedal there is about a quarter or half inch of "space" where I can push the pedal forward before you can feel whatever the pedal pushes against make contact and begin applying braking.
This dead space area will always activate the brake lighting but until you reach that next part under the dash somewhere no braking occurs.
I am quite used to driving my 2010 and this doesn't occur....can not remember if the 99 has always done that and i just realized it or if this is a new issue.
Brakes and stops great with and without load. No issues otherwise. Pedal pops out quickly and normally when taking your foot off.

My stock 2009 ford f250xl 4x4 with a 5.4 and 6 speed has been giving me a weird sound lately started about a month ago and only happens on a cold start situation meaning if it sits over night it will do the sound. the sound goes away after 3-5 min of warm up in my driveway, the sound happens when i push the clutch pedal to the floor. it has no pronounced abnormal sounds through out the rest of the day when its hot which perplexes me, check out the vid on my u tube site for a sound of it.

I have a 1990 F250 with a 7.5 liter and an E4OD. It starting acting up a couple months ago. Tranny would seemingly go into neutral while on freeway. I figured trans was going out... After reading several threads I've decided to try changing the mlps first, got a new one at the dealer!!!. It is the updated one with the connector on the top. I'm currently waiting on a new pigtail from autozone (the original is in bad shape, wires frayed, insulation missing. Also I think when it started having issues we were having some serious rains, which may have caused this connect to get wet.
I believe a previous owner may have had the trans rebuilt at some point. The connect has 6 wires going in it and when I trace those wires back, two are spliced into one farther up the harness a bit. Looks like one is tied into a wire that goes to the solenoid harness. I'm hoping I can cut and splice the 6 wires into the new pigtail and be good.
For now, while I was under there I decided to pull the solenoid plug as instructed to make access to mlps plug easier... the lock is on the backside almost impossible to get to, I messed the plug up all the way around, but not fubarred. When I pulled the plug out, it was soaked in transmission fluid... Is that normal?

So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?
