Ford 6.7L Power Stroke Diesel :: Leak Coming From Front Of Rear Diff
Oct 26, 2013
I have a pretty good leak coming from the front of the rear diff. is this a common problem on the 10.5 ? How hard are these to do without a lift? I still have warranty left but will have to swap out exhaust so its almost a toss up whether I do the seal myself. Also was considering a new posi unit because seems like the original is about toast, might be a good excuse to swap a new one in. 2009 with 95,000 on it. Bought it a year ago with 70,000 on it, the rear was dry till at least 90,000. I serviced the fluid at about 90,000 and didn't have a leak so now a couple thousand miles and its gushing???????

Any success story on converting 2003 or 2004 f350 with leaf spring front end to the 2005-2007 f350 coil front end is it possible?

I just purchased a used f250 6.0L a week after having it i noticed a small oil leak slowly got worse (looked as if it was coming from the too rear of the engine) then noticed about a half quart of oil under my truck. While driving it home the oil pressure gauge kept dropping then going back to normal then eventually dropping for good. The truck still ran so i drove it to take it to the mechanic but then the throttle began to become unresponsive and then gain power again then finally the truck shut off and wouldn't start again, blowing oil all over the inside of the hood and top of the engine. I checked it and noticed the pressure sensor pigtail were fraid so i replaced that along with the sensor and added oil but still wont start.

I have developed a leak coming from the top, driver side, rear of my engine and I could not figure out where it was coming from. I took it to a reputable shop for diagnosis and they tell me that the rear leak is coming from the transmission lines.
The weird thing is I never thought the leak looked like ATF. They also told me that it looks like the stock radiator/cooler has been bypassed so I have no cooler.
Should I assume that the stock internal cooler failed and that is why the PO bypassed it? Also is there a decent write up on deleting these lines and running soft transmission lines to a aftermarket cooler?

While servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.

I've experienced a fuel leak, I've checked all over, and the only thing I've came up with so far, was maybe its coming from the banjo bolt going into the front of the driver side head.. I cant really get to it good enough to tell though..

So I went to the car wash this morning and when I pulled into the stall I heard a somewhat loud rattle coming from my front drivers side wheel. It sounded like there were a couple stones in the cap that covers the lug nuts. That wasn't the case. It did it in reverse also. Before I take it to the dealer Monday morning. Its a 2011 F-350 6.7 Lariat 4x4 w. 32,000 miles. I also have have a little whine coming from the rear when I take off from a standstill.

I don't think it's possible but is there any way to stop this message from popping up in the info centre Every Single Time I exceed 30kmh while the locking diff is engaged? It's winter here on the Canadian prairies and roads are generally snow and ice covered where at live. Makes driving in town really annoying. On My '11 SD I only had to clear it once per drive cycle.

Well hear I am again fix one problem now I got another problem last time it was fuel now it's oil so what I got going on is a oil leak that looks like it's coming from on top the motor on the back I first discovered this nice surprise when I went into the store and came back out and seen two 8 inch round puddles of oil laying on both sides of the motor like I said at the back I thought rear main seal but upon further inspection it's coming from somewhere on top and rolling down both sides of the motor looks like near the turbo what could this be possibly a line or a check valve or seal or o ring on the turbo? Is there a common thing to go bad on these trucks to cause a leak in that area?

I have just acquired a 2011 F350, 6.7, SRW, 4X4, Long Bed, Super Cab with 125K on the clock.
It has an oil leak, not real serious but messy, that seems to be coming from an area above the starter. What is up there that could leak besides the valve cover?
I know that the later super duties have required the removal of the cab for any work much beyond an oil change. I certainly hope that this not the case here.

I seem to not be catching a whole lot of luck lately. The rear end on my F550 has a bunch of play. Going reverse to drive it clunks pretty bad but no ujoints are bad. I can rotate the yoke by hand and hear clunking so i am guessing the ring and pinion are bad, at 100,000 miles. Seems like the rear ends should be more stout than that, certainly look it.
Where to find a source for reman third members since this one had a drop out? Most axle places won't touch it

I am changing the rear Diff fluid in my 1999 F250 Super Duty with limited slip differential. I have read in the manual that 8 ounces of friction modifier is required, ford dealer said it only required 4 ounces. I bought 8.
Also I asked for a inspections plate gasket and ford said use silicone... When I removed inspection plate it had a gasket. So, silicone or gasket or both? Differential capacity is 6.9 pints 75w/140w synthetic.

Nothing to be alarmed about, I'm just letting y'all know I have a coolant leak on the front of the motor. It leaks about 8oz. Of fluid/week.
I have been through the radiator issues, 5 in all on my '08 and 1 on my '11 at 52,000 miles. This one is different, I'm pretty sure it's the water pump.
I'll give the official word as soon as I can get it diagnosed. I guess it's because I tow all the time, nothing real heavy, just everyday use. Truck is hardly ever on its own.

I just replaced the oil/egr cooler, stand pipes and dummy plugs along with all suggested upgrades, just filled with oil hooked up batteries and while filing with coolant it started gushing out from under the intake in front. I think I see an o-ring pushed out.. I hope I can lift the intake without removing the turbo!!!

Was replacing my cracked and leaking charge air cooler pipe Friday evening and noticed oil all over the place at the lower front of the engine. It has been a few months since I've been under the truck. No drips on the ground so it must be a slow leak while driving. Oil level is fine so it hasn't been leaking for long.
Any ideas from this limited two picture view? Front main seal? I've been reading the vacuum pump leaks oil as well but I'm not sure where that is other than driven by the HPFP. I took additional pictures but those were useless, it's a bit cramped in this area.
In the past ten months I've had the turbo coolant inlet pipe leak repaired and then the DEF heater failed, which means replacing the entire pump of course. The wastegate solenoid air compressor noise started some time ago as well at shutdown but I haven't been concerned about that (it doesn't seem to cause an issue). 96,000 miles.

I have noticed a leak coming from the hydro boost piston that goes through the fire wall on the drivers side of my F250 King Ranch 6.0L... Here's the question, does the entire booster need to be replaced or is there an o-ring or a seal that can be replaced in the existing unit. I notice the fluid leaking on the piston just inside the firewall and it drips onto my floor mat.

I have an air leak sound coming from I believe the driver side. Sounds like an air line from a compressor leaking. Could see anything obvious last night or hear well over engine. When driving it's pushing more air. Nothing looked/felt loose. Didn't find any air blowing were I could stick my hand in a hot engine. Doesn't seem to have performance issue, maybe a little more turbo delay.

I noticed I was a bit low on coolant and started looking around. Found a drip on the serpentine belt and harmonic dampener. The T-stat is dry and was replaced 1.5 yrs ago with a full flush. Both hoses are fine and there is no coolant near the steering assembly.
I am figuring it is coming from the water pump. I am planning to put in that Bulletproof water pump and Mishimoto silicon hoses. Anything else I should consider before I dive in. I'll put a new T-stat on since the coolant is drained and it is cheap $20 insurance. BTW hoses and water pump are original (7/05 build date).
Additional information - no spots on driveway (from coolant anyway) and single drop on the dampener. No mess anywhere else and I am down about 1/2 gallon - degas is almost empty.

I have a 06 f250 that has a coolant leak in the front of the engine. It's was leaking about a month ago replaced the water pump it stopped. Then about 2 weeks later it started back up again. It only happens when the engine is cold. But once it warms up it starts leaking again. I am confused as all get out on this.

I just see a fluid by the front passenger tire leak when the diesel is running and ac is on.There was fluid up by both aluminum lines going into a plastic canister in the engine compartment on the passenger side.I couldn't find any cracks in the hoses or aluminum lines..The plastic canister I believe is (AC ACCUMULATOR ) did have a hiss of air when I shut the truck off. I can't see where the clear liquid is coming from. Just started to leak by the front passenger tire.

I started having an oil leak under my truck in the last week or so and when I went under the rig briefly (it is raining here) it looks like it may be either coming from the oil pan itself or the seam between the tranny and engine case.
I thought I'd try the easy solution by torquing the appropriate bolts. Looking for the torque specs for these two sets of bolts or have any other suggestion where the oil could be coming from?
I have ~130K on the truck.
