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?
View 2 RepliesWorking 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 ?

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?
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.
View 1 RepliesI 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.
I noticed the rear end of my F-150 starting to leak from the front of the rear end. What will I need to do to fix it and is there a quick way to fix this issue, as two kids unfortunately prevent me from having much time to fix the issue.
View 5 RepliesMy front diff appears to be leaking from the drive shaft output. it's not enough to leave drips but the skid plates are oily. Having the dealer look next week. 60k on a 2011 460.
View 3 RepliesSo 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 9 RepliesI 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"?
View 14 RepliesI 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.
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 a 2006 fx4. And I am about it change the rear differential fluid. i want to know if i have a a limited slip differential.
View 7 Replieshow 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.
View 2 RepliesI 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 RepliesI seem to have oil leaking from my front differential. The oil seem to be leaking from where the axle comes out of the differential.
View 2 RepliesAny likely culprits? 2002 F150 (with Triton V8 if that makes a difference).
View 4 RepliesThe rear differential is leaking on my 2000 f350, i am going to replace the gasket. When I take the cover off will all the gears pop out or are they held in? Also how much differential fluid does it take?
View 8 RepliesWe have an 01 Sport Trac as a backup vehicle and it has the 3 position rotary switch on the dash for 4wd.
The transfer case engages and disengages but the front wheels seem to stay engaged with the front differential.
There are no manual hubs and I really don't think it should ALWAYS be engaged like that.
What is the probable issue and ALSO can manual hubs be installed on this truck?
Someone mentioned vacuum engagement? but I didn't see any vacuum hoses near the spindles. Didn't see any wires either other than ABS...
I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axle options because of gearing, what axle I have as there wasn't a in owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it...
View 5 RepliesRight after i got this truck it developed an oil leak which i thought was the front main. Turns out after a lot if degreaser and watching its not and its actually leaking from a small tube running out of the passenger side of the engine. I think its an oil cooler line but not sure. Its where the cross member is located and i cant get in there very easily or figure out how to load up pics to the site on my phone. What this line may be?
