Differentail leak 3yrs later...

[bigdog93lx]

Well i just pulled the Cobra out of storage for the winter pepper but after i pulled it out i noticed a small 3inch puddle of differential fluid after sitting for 5 months. Now i have the BF diff brace,but would i have any luck getting it fixed at a dealer for free because of the service bulletin or am i screwed because i no longer have any warranty? Has anyone had any luck getting this fixed this late in the game?

I'm in the same boat. What can you do except for fix it yourself??

there is always JB weld.

You can reseal it with the diff in the car.

ASHLEY aka ~ LargeOrangeFont,

Ever find out where our drivetrain clunk is coming from. Rear end gears or transmission... ? Just curious if you found the culprit yet. ;-)

The JB weld is what I did for the last 1 1/2 year. Now it's time to fix it right.

Getting the diff changed this month probably.. I'll let you know if it goes away after the backlash is reset.

What service bulletin is there?

I've had this problem for the past 3 or 4 years.
A puddle under the car when I go to take it out in the Spring and each Spring the dealership "fixes" it under warranty.

I wasn't aware of a TSB. Can someone provide me with the #?

Did you guys reseal the diff when the brace was installed? This solves the leak issue for most people but it's not unheard of for it to come back sometimes. If you install the brace but don't reseal, it's likely the gasket seal has already been compromised/broken from all of the force being placed on the cover even though it may not actually be leaking at the time.

there is no TSB for leaking differential case/cover

.

I got my car back tonight... and the dealership said it was the plug that caused the leak, not the seal around the cover.

You might want to keep an eye on it. A quick spray with brake cleaner and everyone is happy, for now. Do you have an extended warranty?

Yah, I've already put down new cardboard under the car to see if anything starts leaking again.

Yes, I have extended warranty. Used it a few times.

The dealer goes by the book so once they see that the book says 5hrs they will charge you from 80-120 a hr along with there 75-120 dollar diagnoses. I have a warranty when I bought my car and they wanted to charge my warranty 800+, I ended up do n it myself that way I know it will be done right the first time.

I seriously doubt that... they're jerking you around.

 

[JB]

^^^^ I concur

consider the obvious fact that the plug is above the fill level (unless overfilled somehow)

that means it's only getting splashed with lube, so I doubt it was leaking there

how bad was the leak?

Pretty bad actually.
The cardboard was saturated and it started leaking down... I think even past the rear tire. Enough that it was noticeable.

I'll bet they did not want to or know how to fix it right and whacked the aftermarket warranty company for repair when all they did was clean it.

One of my guys would get fired for that crap!

If it was a Ford ESP warranty it still counts against the Ford warranty group average. So they will try to put off billing Ford for expensive repairs if they just did some recent claims in that category that put them high in group.

Seriously, I'll bet they tightened the cover bolts and cleaned it with brake clean.:nonono:

 

[bigdog93lx]

I'm just going to try and fix it myself. Not even going to waste my time with ford. They will just give me some crap about the diff. brace and my 315 street tires and tell me to screw anyways.

Yup :nonono:

This is why I hate most dealers.
