Ford Brakes/Suspension :: 1989 F350 4WD - Steering Shimmy / Front End Bouncing
May 2, 2005
Truck is an 89 single cab, single rear wheel F350 4x4 with 7.3 non turbo diesel and a c6 trans. not lifted, stock size tires. If you hit just the right bump, regardless of speed, the front end just goes crazy.. tires and wheel shoot violently side to side and its very frightening/dangerous. you can just barely hold the wheel, front end is bouncing and whole truck shakes from such rapid camber change as the contact patch swaps from inside to outside of the tread.
Tie rod end, draglink, steering stabilizer (add on,) shock absorbers (rancho,) and a wheel bearing are all brand new. With each part replaced the shake felt worse (since more of it was transmitted to the steering wheel rather than lost in the sloppy parts) and i took it off the road immediately.
Brand new steering box, put it back on the road, did it again less than a mile away. It rained all day so i haven't jacked the truck up again and really, I am quite sick of this problem.

I've changed brakes on tons of front wheel drive cars, and two wheel drive trucks. But NEVER on a 4wheel drive Super Duty. My truck needs new front brakes now!!!! its a 2003 F350 4X4 -58,000 miles. I was just wondering from you all, how hard is it to change brakes on a 4x4 truck? Do I have to remove the Hub or lockouts?

Have read through alot of the threads and can't seem to find an answer. Bought a used 94 explorer xlt. It came with brand new Wrangler tires. The day we bought it we were driving home and it started shaking and wobbling at about 95kms and but seemed to improve after 115. So I took it to the tire shop next day and had all 4 tires rebalanced. The shop told me that all were out to lunch. The worst was 2 ounces out. Ok cool. Was certain that was the problem. Took off. Got on the highway and same damn thing. The steering seems very tight. No bangs. No knocks. Just the bloody shaking. Oh and also the abs light comes on just as it starts to shake.

2008 F-350 wheel will lock for no reason. I think the Hydroboost has a hair line crack it and when the temp and pressure reach a certain number then it sends brake fluid threw the crack to the caliper? I also heard it could be in the ABS because its locking just one wheel?

I have a 2002 ford f350 sd crew cab, i have changed the front and rear brakes, since then the steering has gotten sloppy. I was driving around 30-40mph and making a sweeping right turn and the front end was wobbly at a low speed it is fine and on a left turn it is fine. It feels like it is the drivers side tire that is the problem. I have to change the tie rod that is attached to the pitman arm. I don't want to bring it to a shop.

The brake line on the passengers side went bad. Called ford for replacement and they said ford is not supplying that line any more. Where I can get a replacement? Its hard line and connects to the rubber line.

Last week I broke my front right caliper. I replaced the caliper, rotor and pads. Now, when I apply the brakes I pull to the left. I took the truck into my repair shop and let them figure it out. They were unable to repair the truck. They replace the master cylinder, all brake lines, calipers on both sides, brake pads, bearings on both wheels, vehicle alignment, tire balancing and tire rotation. The tires are three months old. Prior to last week i did not have any problems braking or steering. Driving at 60kmh the truck goes straight until i gently brake, it will slightly pull left.

Here's the deal:
* Drive the truck after it's been sitting a while (overnight, or at least a couple of hours), everything's fine. Good brake pedal feel.
* Drive 10-15 miles, stop-and-go at lights and stop signs, the brake pedal slowly goes from normal to firm, to very firm. Then, no play whatsoever and brakes are dragging bad. Yesterday, they were dragging so bad that I had it pulled into 1st gear with pedal on the floor just to get thru an intersection.
* Get out and check each wheel, all 4 brakes are dragging. I can tell from the heat pouring out of each wheel. And I've verified with infrared thermometer. Also, I've raised the vehicle when this is happening, and all 4 wheels will not turn. So it's definitely all 4 brakes.
At first, I assumed it was seized slide pins. But I've THOROUGHLY cleaned each and every one, and lubed with synthetic caliper grease. When the brakes are feeling normal, I've had my wife pump the brakes while I watched the calipers. Near as I can tell, they slide easily. Again, when my problem happens, it's all 4 wheels SIMULTANEOUSLY. So I've pretty much ruled out slide pins.
The brake pedal itself isn't getting bound by anything. It moves freely and I've lubed each of the pivot points. No problems there.
* When the brakes are dragging, I can crack the bleed screws and some fluid will come out at each wheel, which releases the brake at that wheel and I can then turn each wheel freely. So, there's residual pressure in the lines. I replaced the master cylinder (twice actually). No change in behavior.
BTW: I thoroughly bled the lines after each of the two master cylinder changes. I must've put 60+ ounces of fresh/clean/new fluid into the system so this isn't related to old fluid.
* Next, when the brakes are dragging, I can unscrew the master cylinder about 1/8-inch or so from the booster, and the brakes immediately release. Again, indicating residual pressure in the lines. So, I assume that something funky is going on with the brake booster. Also, when the brakes are dragging, I can pull the vacuum hose from the brake booster. And after a few seconds the brakes release. So I installed a new brake booster (re-manufactured one from NAPA -- they didn't offer a brand new one). No change in behavior.
After swapping the brake booster, I can still pull the vacuum tube when the brakes are dragging and it'll release in just a few seconds. So, it really seems like something is going on with the booster, but I can't figure out what it might be.
It is possible for the brake booster vacuum tube to have TOO MUCH vacuum, thereby causing the brakes to be unknowingly applied? Is there maybe a regulating valve of some kind in the line?

Feels like the front suspension is blown in the front of my car and i got an alignment not too long ago and the sides are feathering already. spoke to couple of my friends and we have confirmed that the front is blown and also when i drive i see the front bouncing when i go over bumps. I just want to ask the people who did remove their stock suspension and see what brand they are.

I have been "fighting" a front tire cupping problem on my L99 F350 Dually 2wd since I have owned it.
I got LOTS of paperwork with it, one of which was a service ticket from the dealer where it was bought new (with VERY low miles on it) saying several passing motorists had informed them that the front tires were bouncing down the road.
I have read this service complaint several times and I now feel that has something to do with it. I bought the truck with 70k on it some 8 years ago-the PO had installed EXPENSIVE Michelin XPS Rib steering tires on it and they were already destroyed by cupping.
I replaced all 4 shocks, and all 6 tires, begged the folks to FIND something wrong/loose/worn out on the front suspension/steering and they found nothing, they aligned it. THAT set of Cooper Discoverer HT tires did exactly the same thing, except I spent a lot of $$ having the tires rotated.
Now I have a set of Firestone TransForce tires on it and its been to a HD truck shop where I begged them to rip into the front end and FIND something wrong-THEY DIDN'T. THEY installed camber bolts and aligned it, yep, you guessed it STILL CUPPING!!
So, now I'm thinking is it possible that the wrong coil springs were installed at the factory causing this bouncing that the original owner reported to the dealer? I have now destroyed 2 more tires and getting tired of it.

Yesterday while driving, i lost all power steering and power brakes (you would automatically think Booster). I pulled over, popped the hood and fluid was spewing from behind the power steering pump somewhere. I limped the truck home about 20 miles. I checked brake fluid and it was full. checked power steering fluid and it appeared to be empty. Yet when i added fluid it took less than a half quart. I started the vehicle to pressurize the pump and find the leak. Yet the pump never pumped any fluid. (one would thing pump was out) I am baffled as to if the pump went out, why fluid loss? If the booster was out, why do i still have brakes just without power assist? Andif a hose is blown, why such small fluid loss? I dont want to just start replacing parts till it get the right one

I have a 2005 F250 & both front calipers are locking up. I have replaced the front pads, no change, my mechanic installed a new master cylinder. No lockup for about two weeks until today. Front calibers are locking up again.

My 97 f150 had been sitting for a while and after a few miles I could smell brakes and the left front rotor was hot. So I removed the caliper to see if I could free it up. When i push 1 piston in with a C clamp the other one comes out and visa-verse but I cannot push both in with 2 C clamps. When I push the brake pedal they both come out. Its like there is a check valve in the line. How should I go about trouble shooting this?

On braking my front brakes locks up and there's a screeching of tires. Once I release the pedal all seems fine...or is it?
I dissassembled the front brake calipers and cleaned out the cylinder bores and blew out any contaminants from the line. Reassembled and bled the system only to find the pads doesn't move as freely from the rotors as they should. C-clamped the cylinder as far back in the caliper as it will go, pumped the brakes and still the rotor doesn't move freely from the pads, when the pedal is released...which accounts for the radical "loss of power", as the front brakes are holding on.
Bare in mind the vehicle hasn't seen the long road for almost 5 years and has been under the grinder/ welder/ primer/ sanding for most of that period and only moves out in the driveway when it's a good day to work outside.
New flex hoses? Flush the brake fluid from the whole system and start fresh? New caliper rubber seals? Blow the lines out with compressed air to rid of goop? New proportioning valve?

First it was the RH now after replacing the rotors, calipers and new shoes. The LH is now doing it. It doesn't stop the truck just gets hot, the wheel, and u can smell it. The truck is a 97 f150 ext cab 2wd short box, had since new and has over 200,000 miles and going strange until now. I want to get 300000.0 before I let her go. Had to replace a rear axle brake line years ago, and do not think the lines were bleed right, the brakes never work just right.

Initially when I start driving, the brakes work just find. But it seems as I use the brakes, the front brakes build up pressure and slowly start to lock up. They don't lock up completely, but they do cause a significant amount of drag. The rotor, calipers, rubber hoses and master cylinder are all very new. I'm thinking maybe the issue is with the master cylinder and am considering going to get one along with a brake booster(since it doesn't have one currently).

Drove a few miles and both front brakes got hot. The driving was mild failry flat road under 30 mph and the steel rims were hot to the touch around the lugs on both sides pretty evenly.
The van is new to me and I've driven maybe 20 miles so far. The pads are about new, the rotors look fine. Already I've changed all the COPS and plugs, changed the trans oil and filter and installed a drain plug, chaned the engine oil and filter, changed the air filter, and rear drums are on order. So it would be nice to be done soon!

I have a 2007 Sante Fe Limited that has 93k on it. Within the last year I have noticed the steering wheel will shimmy when you apply the brakes at high speeds, it's slowly came to the point now that anything above 40mph will cause the steering wheel to shake while applying the brakes. I am guessing I have warped or unevenly worn front rotors. The car supposedly had a break job done at 74k and this started happening at about the 90k mark.
I was looking at these : Front Performance Brake Rotors Posi Quiet Ceramic Pads for Santa FE 07 09
Second question, any tool list or required sockets sizes to complete a front rotor and pad replacement? I have a floor jack, jack stands, a set of 3/8 deep metric sockets. I also have a breaker bar. This is my only car so I want to make sure I have everything I need before I start taking stuff apart.

I recently bought a 1998 f-250, regular cab, long bed, 4x4, 5.4l triton, automatic. The truck was involved in a wreck by the previous owner and I am trying to repair the damage. He hit some ice, slid off the road, and collided with a log cabin.
The visible damage was done to the driver side front. The bumper, grill/surround, header panel, headlight, turn signal, fender, and hood all need to be replaced. When you drive the truck there is a shimmy coming from the front that can be felt in the steering wheel. When going straight and releasing the steering wheel it pulls to the passenger side. The driver side front rim might be bent? Which might prove interesting if I have to replace it (7x150mm).
This is my first Ford truck. I was willing to take the gamble on fixing it up. I hope that it works out and I am able to do so. What years/models can I source these parts from?

Recently picked up a 2007 Escape with 108,000 miles. The vehicle is in great condition with a full service history. Recently I've noticed a bit of shimmy in the steering wheel and noise from the front drivers side wheel accompanying the shimmy.
At speeds of 50mph+ the shimmy will start. When going straight there is not much of an issue but when a gradual right hand turn on the highway the shimmy starts. Back to straight and it goes away. Not really noticeable on left hand curves.
Steering issue?
Tie Rods?
Bearings?
I'm going to dig into it to get it fixed.
