Ford F-150 (2004-2008) :: 4x4 Not Working - Bad Front Differential?
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?

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.

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.

View 3 RepliesFord F-150 (2004-2008) :: Whine Coming From Rear Differential
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.

Ford F-150 (2004-2008) :: Metal Noise Inside The Rear Differential
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?

I have read through the folders and many websites on 4x4 problems. My problem has to deal with my four wheel drive not wanting to engage. It has nothing to do with the front end or solenoids. When I put it into 4x4, hi or low it will not send any power to my transfer case motor. It wont even illuminate any lights on the selector switch. I have checked all fuses and replaced any relays that have to do with the 4x4. Where I should go with this?

My '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.
View 3 RepliesFord F-150 (2004-2008) :: Rear Differential Leak - Torque Rating On Bolt?
I am getting a little frustrated with a leak on my rear differential. The leak is on the front of differential rear-end just behind the four bolts you take off to remove the driveshaft. When you take the driveshaft out, there is a single bolt and the seal behind that is leaking. Here is my dilemma, I called my local ford dealership to find out what the torque rating on that bolt is so when I replace the seal I don't over-tighten. He told me there is no torque rating on it because I have to tighten, measure, tighten, measure the bolt. I was lost, I didn't have a clue what he was talking about.
View 6 RepliesFord F-150 (2004-2008) :: 4wd Not Engaging Properly Only Light Works
I have an 06 f150 xlt 4wd 5.4. I bought the truck about two months ago and have come to realize that my 4wd is not working. The light works and you can hear the clunk but recently we got alot of rain and i was going down a georgia clay dirt road and almost got stuck in the middle of the road. i tried 4hi and 4lo but only the rear wheels would spin. I had my wife put it in 4wd while i looked under the truck and the half shafts do turn in 4wd. which doesn't make any sense to me. I also unplugged to vacuum line from the intake and capped it off to try and let the hubs engage that way but still nothing. why would the half shafts be turning but no power to the front wheels in 4wd? does that mean the iwe's are stuck engaged? Which would explain why they turn all the time. But if they are engaged, whether they are stuck or vacuum leak or whatever the reason, shouldn't the front wheels be getting power.
