Ford F-150 - 1997-2003 :: 1998 2WD - Rear Axle Vent Tube Blowing Oil
Nov 27, 2009
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 own a 2004 F-150 FX4 5.7L V8, I notice this morning that I had gear oil coming out of my rear Axle Vent Tube. What would cause this issue? I'm kinda at a loss as to what would cause it.

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???

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.

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.

1998 F-250LD 4X4 ... The outer boot is cracked, so I got a new one. Took the axle off, but cannot understand how to remove the boot. Where do I take the joint apart?

I have a 98 F250LD, its a Lariat, so everything electric/auto. Shift on the Fly 4x4, 5.4, 188K, Factory rear air suspension. Typical Minnesota rust. Anyway, I just noticed in the last 75 miles or so, a drive-line vibration. There is nothing until 39 MPH. Then from 39-41 MPH there is a decent vibration. Stops until 50, then from 50 MPH up it is a steady vibration. I have already changed the u-joints in the rear shaft. I have pulled/wiggled on everything else I can think of with no luck of finding of anything loose.
One thing I did notice, is that the front axle is locked in all the time. How long it has been like this: years for all I know... I can flip the switch from 2wd to 4H and 4L. It all seems to work fine, I hear clicking, the 4x4 engages, the proper lights come on/off. The front axle will pull when supposed to. The transfer case seems to be working fine, but the front axle won't disengage. I am hoping this can be fixed cheaply/easily (DIYer), and also hoping this explains my low fuel mileage.
Front axle? Where to look or what to try and fix for the vibration?

I had a loud whine from the rear axle of my 04 SCREW and had the bearings replaced at the dealership. It has been about a year/12k miles since it was done and I just noticed that the vent hose is missing. I'm not sure if they left it off or if it fell off on its own. Anyway, my question is, do I need to replace the fluid once I put a new hose on? I'm not sure how much if any dirt or water might have gotten in there. Also, where does the hose go up to? I figure it must clip to the frame somewhere.

98 F150 2wd 5.4 -even though VIN says its "W" 4.6; it has a 5.4 with 4.6 timing setup-found. But that's a whole other story...
So, Replaced heater core. did the blend door too.
A week later it overheated and blew a heater hose off the core at the firewall (several times). Temp was up and down, forced me into cylinder head protect mode, so i called my mechanic.
Mechanic used a sniffer (blue liquid turns yellow) in my overflow tank and there was exhaust gas in it... so we replaced head gaskets, intake, timing, water pump, radiator and the rotted out rad support.
Got it done and back on the road, but a few weeks later and the heater hose quick disconnect blew off again, spewing coolant all over (again). This was what we thought was part of the original problem- head gasket allowing cylinder compression into the coolant passages. the little rubber hose that comes from the back of the intake and goes up into the heater core builds enough pressure to pop the disconnect right off and I dont know why. Like I said- I thought it was the head gasket blowing pressure into it but that's all been replaced. Why the pressure would be so high at that point, and how do I correct this?
This is my daily driver, so for now I've bypassed the heater core, but I'm afraid that pressure is gonna burst a hose and/or fitting again.

I have a 1998 F-250 LD 4x4 with 462,000 km. I have been hearing for some time quite a drone coming from the rear axle. I am guessing the wheel bearings are due, as both front ones have been replaced, but never the rear. More about the noise, I hear it come to life as I gain speed. The faster, the louder. If I decelerate the noise is still present, but volume significantly decreases. Should I change the oil and friction modifier and see if there's an improvement or go ahead and change both bearings too?

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.

1998 F150 XLT 4.6l automatic,,,
Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?

I got a 2002 f150, right now it has a 9.75 with disc brakes. But it exploded. I can only find a 9.75 with drums in the wrecking yard. Can I just swap my disc brakes on to the axle with drums?

What the exact part number is for the seal for the rear axle in a 2003 F150 4x4 ?? Mine decided to leak yesterday and so I looked up Ford for the part but there's two .. one is thick and one is not. I don't want to take the seal out first to look because I got no other vehicle to get it and putting it back in and out would be silly.

Looking for a video, pictures, or steps that are in depth on how to replace my rear seals and bearings? They are leaking very badly and would like to see some other ways to get it done.

I have a constant whine going down the road with foot on the gas. Back off and it quiets up. At 2-3 MPH i think i can here a " tick- tick". Took the drive shaft off, wheels off ground, cover off and oil out. Spin wheel and i can hear a tick - tick, I think around the pinion bearing. No play up and down or in and out, but it appears to have 2-3 times the backlash i would expect. I used the screw driver- stethoscope--- still think its the bearing. This is a 9.75 axle. What kind of luck would I have pulling the yoke off and going in from the front without removing axles halves and ring gear? I thought I had read that here before. Never done one that way .

Truck is a '99 2WD with drum rear brakes. 81K miles. I rebuilt the rear brakes due to a leaking wheel cylinder. The old shoes were not completely gone, but were worn evenly - everything looked normal.
Not a professional wrench, but I've been re-doing my own drum brakes since the '60's, so it is not rocket science to me. Still, as a precaution, I did them one side at a time so as to have reference point, and also snapped a few cellphone pics just to be safe.
Replaced both wheel cylinders, all hardware, and of course the shoes. Gravity bled the cylinders first, followed by the old tried-and-true, wife in the driver's seat, "down-and-hold, now up" routine. Adjusted shoes to just contact drums lightly, and buttoned it up.
The problem is that I'm getting a violent chattering from the rear axle with either light or normal braking. The chattering is worse as the brakes warm up - shakes the whole truck. At first I thought I had a bad rear ABS sensor, but then I did a couple of stops just using the parking brake, and got the same chattering.
Now I've pulled the drums off to re-check. There is nothing loose, nothing out of place, nothing leaking, but there was a heck of a lot of brake dust in there and the lead shoes on both sides were noticeably more worn than the trailing shoes - and I've driven maybe 100 miles since the rebuild.
You can't reverse these shoes, since the trailing shoe has a peg to hold the automatic adjuster, so that is not the issue. The drums were turned less than 1000 miles ago, so I did not have them re-done at this point.
I had my "assistant" partly depress the brake pedal while I had the drums off to confirm that the cylinders were expanding both shoes, and they are.

so while replacing the rear brake lines in my 2001 F-250. / 5.4, the flex line that drops from the frame bolts to the axle through the axle breather threaded vent line. The friggin thing crumbled on me and now I can't find a replacement for it. Where I can get it or what it's actual name / part number is so I can call the Ford dealer and hope it's not obsoleted?
