Ford F-150 (2004-2008) :: Front Differential / Axle Vent Location?
Jan 1, 2017
Looking to change out my front differential cover tomorrow, cover is pitted, rusted, corroded, and leaking at the seals. While under there I want to inspect the vent for the axle and differential (and replace if it's clogged - which I believe is leading to the seal leaking). Looking for info about the vent tube location on the front axle? Thought I read somewhere it was on the cover itself, turns out that's a negative.

97 3.0 2WD, Where is the differential vent or does it even have one? I've got a rear axle seal leaking.

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.

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.

Working on a 2004 Ford F150 4.6L. No 4x4. Replaced both IWE front actuators. (Neither one would hold vacuum). Still no 4x4. I realize I have vacuum issues and may be excessive wear on gear teeth of the front wheel bearings. The issue that really bothers me is the front differential. Having placed the truck on jack stands and running in 4x4 should both front wheels be turning ? The right front wheel turns and the left front does not move. Is this normal or should I pull the front differential cover off ?

My front differential is leaking. Are there any special Ford tools required to replace the seal? Or is it simply bolt (and fluid) removal, seal replacement, fill with new fluid. Any tips or heads-up on this?

2006 F150, SuperCrew with 5.4
I just replaced the firewall actuator valve for the hubs, and went to try out the 4 wheel drive. The hubs engage and lock to the axle shaft, the transfer case engages and locks to the front driveline, but the front differential isn't doing anything. Is there an actuator for the front or did something break inside?

I am on the fence with getting rid of my 7.3. Here's why. Whenever I crawl underneath the truck or look under the hood I see all these different oil/fluid leaks. She has less than 200k miles and I use her to tow my boat to go fishing.
Right now I am trying to weigh if the truck is worth keeping or selling and then getting a new/newer truck.
Here are some leaks. One is obviously oil and coming from what I guess is the front main seal. I really don't know. The other leaks going onto the U-joint look like oil leaking down the axle from the front differential.
I'm growing a business and not sure if I have time to play mechanic. However, everyone I talk to always exclaims, "You got a 7.3?! You luck SOB!" and I am kinda getting the feeling letting her go would be a mistake. FWIW, she is paid off.
Other than a slight wobble in the steering wheel at speed, she runs like a hoss.

My 2013 f-250 with 6500mi. has peeling paint on the front differential and the axle.. I sprayed it with some fluid film for now.

Tried searching, but I couldn't find any good write-ups on how to replace a front CV axle. The boot on mine is ripped and spraying grease so I figure I should just replace the whole axle while I'm in there. In a previous post, I also found out that replacing the CV axle (joint?) is easier than replacing just the boot.

I have a 2004 F150, 5.4L V8. A few years back I was in an accident when someone slammed into the front of my truck. The right front wheel & tire took the brunt of the accident. I thought the repair shop had everything back to normal until recently I occasionally have a grinding sound coming from the right front side, seems to be related to the axle. It doesn't do it all the time just at random while I'm driving. The only solution I can find is to pull over or slow my speed to a crawl. Once I slow down enough or turn my wheel one way or the other its like something SLAMS back into place. I had it looked at by a local mechanic and they couldn't find anything wrong. Could it be something in my right front axle?

My 2008 Santa Fe has a problem where the heater & A/C work fine, the fan is blowing a lot of air but it will not switch between the defrost, heat & floor locations. Right now about 90% of the air is blowing out on the floor(freezing my feet with A/C) while about 5% comes out of the dash vents and 5% out of the windshield vents. No amount of adjusting will change these. I've changed the cabin air filter which didn't work and have ruled out the fan as it sounds great and pushing a lot of air out at the lower vent.

So back in mid May while driving the inlaws back from the airport in our newly aquired 2004 Mercury Mountaineer 4.6 AWD with 100K on the clock, I started to hear a high pitched whine. Stopped at the rest area and found gear oil coating the underside of the car. It was coming from the differential vent. Long story short, the axle came off where it was supposed to be in the differential and cratered it. Got it repaired through the extended service plan I had gotten with the vehicle. Fast forward to today. About 70 miles from home again at highway speeds I hear the same whine and see smoke, pull over, same oil. Get towed back to the same dealership from the previous time and its sitting in their lot til they can look at it on Monday or Tuesday. Fortunately the dealership does warantee their work and parts so it should be covered, its just frustrating.

I got a new to me truck. It's a 2004 F150 Lariat 4x4 with the 5.4L. It's got a whine that I believe is coming from the rear differential. I'm going to change the fluid. My axle code is 26 which I believe is 3.73 non-limited slip. My owners manual says to use 75w-90 but I've seen a lot of posts on here that say to use 75w-140. Which is right or better? Also, is my rear differential the 9.75"?

I have a 2007 ford f150 FX2 5.4 with 3.55 limited slip rear end. It has 68,000 miles and would like to change the rear differential oil. I have read and I know the oil it requires is 75w-140 plus the friction modifier. I would like to use mobile one. But was reading and the mobile one sites states that is already has friction modifiers. Is that ok to use on my truck? Using mobile one and not adding the extra modifiers?
Also some other brands say they have friction modifiers as well. Should I use mobile one and add extra friction modifier or just go with what it has already?
Mobil 1 Synthetic Gear Lube 75W-140 LS contains special friction modifiers designed for limited slip-type differentials. In most applications, the addition of special LS (limited slip) additives is not required. For axles requiring the highest level of limited-slip performance, OEM specific LS additives can be added to this fluid.

The rear axle in my dads 1998 ford ranger has been vibrating for quite a while so I pulled the cover today and found that the fluid was full of metal shavings, it was glittering. I also found this metal chunk in the differential so my mechanical experience tells me this is not a good thing. I am taking it apart tomorrow any tips or do's or don't? Also, what this metal chunk is and what that knurled up end is??
Door tag told me it was a 7.5 open 4:10 axle.

Alright so about a few weeks ago I started hearing what sounded like it was time for new brake pads. But the other day I turned the corner and my neighbor came up to me and said he heard my truck making a metal on metal type noise. So I said okay fml, took it to a local mechanic.
Called me today and said the brakes are fine but it's rear differential, he said they put the truck on the lift and used the stethoscope and heard a metal noise inside the rear differential and said that the fluid in there was very metallic.
I bought this truck about 7 months ago from the dealership. It has a total 90,000 miles on it. What does it look like this could cost me worst comes to worst?

how hard is it to replace the U-joint at the differential side of the shaft on an 04 FX4? Any special tools needed? At low speed (5-10mph) sounds like someone tapping on the rear end with a ball peen hammer, I guess it is the u-joints.

Finally finishing up my 2001 F250SD 4X4 project. Decided to pull down the front axle to replace the dust seals. I've got everything apart including the large knuckle seals. Tried to pull the passenger side axle out but it only moves about an inch to an inch and a half before it stops. Took off the differential cover to look for damage or something obvious but I don't see anything wrong. The axle is moving within the splines of the spider gear but that's it. Stumped and sitting on jacks!
