Ford F-150 - 1997-2003 :: 1998 4.6L - How To Remove EGR Tube
Aug 25, 2017
1998 F150 4.6L. Pretty sure EGR is bad. Clogged ports cleaned, DPFE changed, etc. Tried the suck test on EGR, no change. Still getting 401 code. Ports were really bad, so I figure EGR is clogged/bad also.
Here's the problem....I can't get the nut loose that holds the tube from the manifold onto the EGR. It is on the back side of the EGR facing the firewall. Not a whole lot of room to work with, but I can get a 1-1/16 wrench on it. I have tried soaking it in PB, heating the EGR body with propane, beating on it with everything I can find, and it still won't budge.
If I unbolt the EGR from the TB, I have no leverage on it.

Ok, I have a 98 F150 XLT, standard cab, 8 ft. bed, 2WD with limited slip - if any of that makes a difference.
The rear axle vent tube is literally blowing oil out the top, where it's loosely connected to the bed. It does this every few weeks. I pulled the hose and ran a rifle cleaning rod down it to make sure it wasn't plugged ... it wasn't.
It seems like it's building up pressure somewhere, then blowing all at once, but why?

I have a '98 F150 front 60/40 seat going into a '77 shortbox F100. I've searched and found a lot of info on repairing a lumbar support but nobody seems to mention how to get the stupid off. I don't want to break anything but I can't see any screws or clips. Does it just pull off with force?

So I've driven my 97 F-150 (4.6 L) around for several months now listening to that wretched left side exhaust leak caused by the nut on the EGR tube rotting off the nipple on the manifold. I tried plugging it, taping it with that exhaust "bandage" tape, etc. Nothing obviously ever lasted. And I sure didn't want to try replacing the manifold and then dealing with the potential broken studs, etc.
Then I finally got around to getting the gas tank straps replaced with that recall. So I took it to the dealership this past Friday. I mentioned the EGR tube leak kind of in passing. The service manager said they could fix it for about 80 bucks. He said they had successfully removed quite a few of those nipples without replacing the manifold. I kind of thought to myself "yeah right" (considering I live in the rust belt with all the road salt, etc.) and told them to go for it.
Not surprisingly, they called me back later in the day and said they couldn't get it out, and he wants to replace the manifold, etc. I just told him to plug it instead. When I picked up the truck, I learned the mechanic decided to WELD it instead of plugging it. I was pretty surprised that he tackled it, and he actually did a pretty decent job in sealing it except for one small pin hole on the back side between the welds. I mixed up some JB Weld and filled the pinhole. The welds may fail or the JB Weld blows out tomorrow, but, in the meantime, I don't have to listen to that wretched exhaust leak constantly. At least I'll have a few days peace if not longer

Rusted dipstick tube I thought was going to be an easy enough fix. Broke off clean at the block. Tried for hours, easy out, prying, vise grips anything I could think of. Well I tried to pry the side of the tube over to make room for my needle nose vise grips, and boom. Down in the oil pan it goes.
Do you think theres any way possible I can fish it out through the drain plug. I really dont want to pull the darn motor.

I need a front axle tube for a 1999 F-150 4x4, I have tried local parts houses and dealership with no luck. Any information where I might locate one.

I got a 97 F250 4x4 w/ 4.6 lt. motor & auto trans. The engine is leaking oil. It looks to be coming from a set of hoses that are on the adaptor that is between the oil filter & the engine block. Also what are the oil lines called? It is leaking motor oil not transmission oil.
Also just pulled my oil dip stick & the whole thing (dip stick & the tube) came off the truck. Seems the tube has rotted away at the oil pan. Is this also a job I can do?

I have a minor leak at the base of the trans dipstick tube. I assume that the tube is press in ? has an o-ring ? I put some silicone around the area and that worked about a week, the fluid is probably eating through that type sealant. The trans is a 4r70. Seems to me that the actual tube should be ok and having never dealt with replacing one I want a little advice before yanking it out.

Ford F-150, 1999, 4WD. My dipstick tube has rusted off right at the point where it attaches to the engine block. I purchased a new one but I'm not sure if that's a job I can do on my own. What installing a new tube will entail?

My 98 mountaineer keeps throwing rear end oil out the vent tube.. Why does it keep doing this?? its been doing this for a while and had to change an axle seal, I think because of this. It stopped doing this for a little while after I changed the seals and put in new oil.. Its not over full.. When it stopped I figured it was because the oil was old and was foaming or something.. But now its back to doing it again... The tube is not plugged.. Why does it keep doing this???

When I turn off the ignition and try to rotate the ignition switch/key to the steering column lock position it will not go all the way. It stops just before locking the steering column and I cannot remove the key. This is an automatic with a gearshift on the column. I have to reach up with my left hand to pull the gearshift lever up as if to pass the PARK position. While holding the gearshift like that the ignition switch can be rotated to lock and key removed.
I had the dealership attempt to fix this twice while under warranty with no success. After 10 years I am sick of it and would like to fix it. 2002 Ford F150 4x4 5.4L automatic on column.

How does it come off. I wasn't able to turn the axle vent without turning the block on axle for the brake lines.
I would like to remove the brake system from my current axle without breaking any lines open, then putting a new axle in and put the brake system on the truck to the new rear axle.

My 1999 Ford F-150 failed inspection for frayed driver-side seatbelt (a common problem according several parts sellers). I have obtained a used shoulder harness assembly from a salvage yard but I have two questions:
What is size of the Torx bolts? (the star shaped ones) Looks like T55 but I don't have any to compare. I'll need to buy the socket and I assume a generic version will fit my ratchet.
The top part of the harness looks simple enough to remove but do you need a ratchet extension to remove the bottom bolt?

I have an 02 f150 2WD with a "leveling" kit. It was on the truck when I bought it. However, the front sets noticeably higher than the rear. The rear has lifting blocks, while the front has the lifted spindles as well as the coil spring spacers. At least I think they are spacers. I had to replace lower control arm bushings a while back, and there were black plastic rings on top of the springs. Can I remove the spacers? If I can, I plan on doing that and replacing the rear blocks with whatever I need to get the stance back. I like the height of the truck now, just hate the front being higher than the rear. I do pull my boat with it.

I am having a problem with my 1998 F150 4x4. The 4WD is not engaging. It is a manual shift. I have checked the transfer case by turning the drive shaft in 2WD it is free. When I shift into 4WD it is does not spin freely. So I believe that is OK. I have checked the vaccum diaphram. It will move the piston when I attach a hose and pull vacuum on the inboard hose barb. So I believe the diaphram it self is OK. I am not sure if the hoses and selenoids are OK. They look fine. However there is a constant vacuum on the inboard hose line (red/pink color) wether I am in 4WD or not. Is this OK? How can I check the selenoids. If all this is OK, the next thing I believ it could be is the shift fork in the differential. Is that a difficult job? Do you need to pull the whole axle out to replace it?

Just bough a '98 F150, 4.6L; drove it home and it ran great, lots of impressive power etc... Parked it my shop and getting it ready for safety check so I can register it. All I did was change the oil, oil filter and air filter.
Couple weeks have gone by, I went to start it and it does start & idles beautiful but it will not rev. I give it gas and it's like it's choking / wants to die. The signal lights are flashing super fast which I don't recall doing before. Battery wasn't holding charge so I installed a new one tonight; no difference. Alternator is good.
I have not checked the plugs yet because I don't think that would be the cause of an overnight change from running excellent to what it is now but I will check them.

I have a 1998 F150 4.6 that has a misfire with no CEL. I have already tried the following: checked fuel pressure, change cam shaft sensors, changed coil, checked MAf seems ok, spark plugs and wires. On my scan tool it wont show any misfires when obviously its misfiring. When driving it will run good for about 10 seconds and then misses for about 10 seconds and it just keep going in this loop.
