Ford 7.3L Power Stroke (1999-2003) :: Boost Tops Out At 29 - 30 Psi And 1 - 3 Down The Interstate
I believe I am having spooling issues with my 2000 f250 7.3 automatic truck. I now am running a 67mm billet compressor wheel with a 1.00ar turbine housing and high flow outlet so basically a thrust bearing 38r . I'm running oem sticks and PHP tunes on my hydra. On the 140 tune egts top out at 1200* uphill. So egts are not a problem. Boost tops out at 29-30 psi and 1-3 down the interstate. I see a lot of trucks that can hit 20+ psi in second by just squashing the skinny petal and I could also do this with my oem turbo. Mine takes awhile to get psi up like I said it will hit 30 if I'm petal to the carpet for a few and get going but I feel like it's not spooling as quickly as it "should ".
I completely built this turbo with new parts nothing was reused down to the heat shield behind the turbine wheel inside the turbine housing. I used all American And Canadian built parts . 360 thrust and a banks 1.00 turbine housing. When I bought the turbine shaft and compressor wheel it stated that they where pre balanced and I could clearly see the balancing marks on both but the shaft and compressor wheel are from two different manufacturers so there was no way to be sure that everything would align and be balanced. Basically my question is do you think it would to be wise to have the assembly balanced? Could this be the reason the turbo doesn't spool as fast as my oem gtp38 did . I've been running the turbo for four months now .

Shortly after i bought the truck and started driving it home, it shut down on me while coming up a mountain on the interstate. I had probably drove it about 10-15 miles and about 20-30 minutes of running after being dead cold. The temp gauge was about in the middle and it would not start up again until about an hour and a half later, which I was able to drive it home another 20 miles away.
There are no codes, which a mechanic told me it is probably an intermittent problem then. He then told me it would either be the cps, ipr or fuel pump. I have changed the cps and since then have not been able to replicate the problem but I have also not been able to get the engine up to temp because of the recent weather being so cold. I want to test the truck and see if I can get it to stall again but what this could be or what I can do to test the truck?
The truck is a 2003 f250 7.3 4x4 automatic, short bed, crew cab, with 320k miles.
Ford 7.3L Power Stroke (1999-2003) :: No Brakes Or Power Steering
I've got an 01 7.3 lariat 4x4 with an 03 7.3 engine in it (long story behind that) but basically I noticed one day I had a hissing underneath my dash and my brake pedal was a little spongy but my truck stopped, well before I could get it to a shop and checked out it went bad. Coming up to a stop sign and as normal hit my brakes and right before it came to a complete stop the pedal shot to the floor and I lost power steering as well as brakes and went rolling out in the road and almost got hit. So it's been parked ever since and I have changed the hydroboost, the power steering pump twice, flushed everything and bled everything and still nothing, can't even find any leaks. What to even replace now or whether to just take it to a shop and spend another small fortune.

I've got an E99 powerstroke. Recently it's been getting hard to steer, if not impossible. When I'm parked i can't turn the wheel and it gets better if i Rev the engine up, driving is usually ok and going around corners. It's just low speed, low rpm that it won't.
Also every once in a while when braking it feels like i lose all power brakes. The pedal goes to the floor and the brakes let go, then i can feel the pedal pump back up and i get a good feeling brake pedal again that actually stops well. All this happens within about a seconds time. But the steering is by far the worst.
I just did the power steering flush with atf and it didn't work. I'm thinking i need a new power steering pump, but want to ask here first to make sure. The truck has 290,000 on it, and it never has been replaced to my knowledge. I bought the truck with 147,000 however so it may have been done before that.
Ford 7.3L Power Stroke (1999-2003) :: Lost Power Steering And Brakes / Pump Started Growling
Driving home from movies tonight, I lost power steering and power brakes and the pump started growling. Looked in the reservoir and it was all foamed up. Within the last 20k mi I have flushed the system and refilled with power steering fluid. No apparent leaks at this time. And happened like someone flipped a switch. Fine one turn, nothing the next. What are the chances this is a fluid issue and not a mechanical one? Start with flushing system and adding Mercon V? Or is it likely pump is damaged?

View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: Brakes Sometimes Soft Other Times Firm
So the other day I had someone change lanes and slam on the binders right in front of me which caused me to slam on mine. Luckily no one got hit. Now my brakes feel different. Sometimes the pedal feels nice a firm other times it pushes in 2-3" before starting to brake. The fluid level has not changed in the resevoir and the hydroboost appears to be working fine. The power steering is still operating as before. I have checked the calipers and none are leaking.
My suspect is the master cylinder but was wondering if the symptoms are common with the master cylinder failing? I'm thinking internal o-ring has failed due to the near accident event. I'm going to do power steering flush just because I never have. Is there anything that would display these symptoms that I could check before buying the master cylinder?
Ford 7.3L Power Stroke (1999-2003) :: Brakes Overheating - Front Right Rotor And Hub Very Hot
I was driving on a short business trip and I noticed what I thought at first was clutch smell, and then I realized I had a brake overheating. I pulled over and the front right rotor and hub were very hot. The caliber not so much. I let it cool while I was at the meeting. About 1 1/2 hours later I jacked the truck up to see if the bearings felt bad. Seemed fine so I drove home trying not to use the brakes and the heat did not return. I replace the caliber with one from Ford, but the only lines I could find were from CARQUEST and they are made by Raybestos. I am assuming that these lines are made in China.
I have been looking for some braided SS lines, but can't find any for a 2 wheel drive dually with 4 wheel ABS. Where I can order some better lines???
I hated my old 1994 F-350 that had those Metal/rubber pins, they would mess up and overheat also, I thought that my 2000 would not have this problem, I was wrong.
FYI, about a month ago I replaced the rear pads, and changed all the brake fluid with Valvoline synthetic DOT 3. I installed Akebono pads on the rear and just today Akebono on the problem front side. Will change out line and pads on driver side later this week. I hope I got if fixed.
Ford 7.3L Power Stroke (1999-2003) :: F250 - Brakes Shudder While Stopping
I just bought my first truck and it is a 1999 (Made in late 1998) F250 7.3 Super Duty it is 2WD with rear ABS and has 290k miles on it.
It has what seems to be the common brake shudder while stopping. I know the only solution is to replace the rotors and I have been looking all over the forums and internet and just don't know what to go with.
I'll be using the truck to do light farm work, pickup lumber, get a bed load of dirt and maybe pull a normal car trailer every now and then.
I'm wanting to get something that will prove to be trouble free long term and be good enough for what I need with out over paying for something that I will never fully utilize. I have looked at

Frozen Rotor
EBC - which doesn't have 2wd front rotors
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - Truck Jumps When First Step On Brakes
Tires have less than 10,000 miles on them, and air pressure is within 2 lbs left to right side.
New calipers.
New soft lines.
New hard lines.
New pads.
New rotors.
New ball joints.
New tie rod ends and center link.
New front axle universals.
Brake fluid and all other parts are less than 6 months old. I can let go of the wheel and the truck tracks straight, 10mph to 100 mph. Whether I am going 10 mph, or 100 mph, when i first step on the brakes the truck jumps right. Needless to say, the faster i am going, the worse it jumps.
After first brake application, truck tracks straight. Let go of the wheel and it tracks straight from 100mph to a dead stop with brakes applied after the initial jump. Whether I am hard on the brakes or gentle, it does not pull at all. Only on the initial step on the brakes.I am at a loss as to what the heck is wrong with it.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smoking Brakes / Puff Of Smoke At The Front
Picked up my 5th wheel this afternoon from being raised 3". Dropped over the 10 percent grade down the hill to normal driving. Had the trailer brake controller to boost #2 (Prodigy controller). Had to brake pretty continuously, (tried to stay off it a bit, but is is about 10 grade for about 3/4 mile. Put the auto trans in D2 to get brakes come to the red light at the bottom. Noticed a puff of smoke at the front. Driver side, didn't notice passenger side.
New pads and new slotted rotors new maybe 1,500 miles ago. Not liking that action, but need thoughts. Want to put a thousand or 2 miles towing this summer and accompanying mountainous terrain and back.

Ford 7.3L Power Stroke (1999-2003) :: Brakes Lose Pressure Entirely And Pedal Goes To The Floor When Hit Bumps
The problem occurs when you hit bumps while braking, or if you get on the brakes to hard. It seems like the brakes lose pressure entirely and the pedal goes to the floor. It kicks back in when the ground smooths out, or if you are braking hard it slowly grabs again. At first i thought it was sliding, but it definitely is not. The truck appeared to be equipped with abs but the previous owner seems to have cut the abs wire/sensor at the hub. Another thought i had is maybe the brakes need to be bled and have fresh fluid put in them, I have not tried this yet (Plan to this weekend along with a dozen other things). Its rather scary when it happens. but i didnt think much of it until i nearly rear ended someone..with my younger brother in the car. Now i need to fix this asap.

I've dealt with this issue many times before but this time I am at the last straw. I cannot deal with squealing brakes!! I have tried OEM, napa brand, auto zone and everything is fine for about a month into it and than they start to squeal. I always use the high temp ceramic brake lube on all brake parts. I have cut rotors, changed rotors, changed pads, prayed to the brake gods but nothing has worked. I was curious to see what everyone is using out there and maybe there is one brand that everyone is choosing over the others out there and having great result.

I have a 1999 ford f250 lariat 4x4 with 236,000 miles. Recently I have noticed when I am applying the brakes it sounds relatively normal until about 30 mph then it sounds almost like I have a flat tire or I'm running over a rumble strip, It's almost like a popping sound but a deeper sound.. I'm not sure how to describe it. The truck also vibrates violently when I reach speeds above 65-70 mph. Until about a week ago I could go 100 mph with no vibration whatsoever.

While I'm cursing at highway speed everything is fine. But when u punch it it pass someone it's like I actually slow down, same from a red light. I've got a livewire programmer in it and this problem is somewhat new. It just seems to keep getting worse, I was going up a hill on the interstate this morning and at 2800 rpms I was actually slowing down. I'm not sure if the fuel pump is going out or if the transmission is slipping or what.

I have a 2012 F350 I keep the hubs in auto all the time. In the winter I just flip the switch to 4 high when I hit snow conditions. I know to shift in or out I need to be below 55mph. How fast can I safely drive in 4 high on the interstate? I drive hundreds of miles at a time in the winter. Some times if the roads clear I will cruise at 70-80mph. This is a question of mechanical safety on truck components not driving safety.
