Hello, mostly this is just for everyones info.
I have an 2007, SC, 5.4, 3.73 LS, 4WD, 36,012 Miles.
AF1 3.5, Dyno tuned.

The front seal on the rear end is leaking, enough that i can see drops on the newly paved driveway.

I will be calling for appointment tommorow.

Is this a common problem?

Can i expect problems after the drive shaft is removed and re-installed?

could this leak be caused by hard starts off line?

Hope you all have great day.

 

My rear-end started leaking at 90,000...began roaring, and had to be replaced for $1,700.00 by the dealer.

 

that's a shot to the crotch!!

 

I doubt hard starts could do it, but if your wheels don't break free of the pavement and you torque the axle to create a big angle on the driveshaft, it's possible.
While you're at the dealer, have them check your rear wheel seals on the end of the axle shafts, they tend to fail early on some. Good luck.

 

One of my rear axle seals failed this summer, around 78,000 miles. It was seeping fluid, nothing major, but I went ahead and had them replaced.

F150online member Patman03sprCrw did them for me, I was the parts gopher.

 

Fortunetly my 3rd party extended warranty paid for it.....
they initially denied the claim and said my mileage was actually OVER 100,000 miles due to my 275/70-R17 which they called "over-size" tires.......

After a firm discussion about the ATTORNEY GENERALS OFFICE in Tallahassee, Florida, they paid the claim. A$$holes!

 

Both my rears are seeping @ 75K on my '05

 

Glad to hear you got it worked out... but their logic doesn't make sense... If the tires are bigger than stock, then the vehicle isn't turning as many parts to move 1 mile... I guess they were saying that the ground it covered was more than 100K miles... but your wear on the truck for 100K miles with "oversized" tires would be less than someone with "stock" tires, since your truck didnt have to turn the axles as many times... but still.... a mile on the truck is a mile on the truck, regardless of tire size as long as the truck's computer is tuned right

 

And this is why they don't hire smart people like you....you would make too much sense and cost them money.

 

HAHAHAHA..... That was my point........ I had the last laugh!
