Sounds like you know people with some shitty luck. That rear end has been around forever and I've never heard of anybody breaking one.


10 bolt corporates suck.
Pinion bearings are notorious to fail. The front bearing lacks proper oiling, gets hot and seal starts leaking
I wouldn't doubt I've replaced a 100 of them. As clames said, the 8.8 and sterling are much better.

Ok. Nobody cares though. Again, people are not out there snapping 10 bolts. They are overheating 4.6's though. I guess Chevy > Ford

I've never experienced the 4.6 overheating problem while towing.

And Chevrolet is better than Ford lol

all of them were driven daily by employees with a moderate load of tools on them all the time....so there is absolutely no telling what kind of bullshite they were doing in those trucks....whatever it was I would bet that if those trucks were driven by the owner they would have been in better shape unless the owner was a moron....


True story. We used to have about 20 trucks, mostly Ford, F250 and E250 vans. Usually with a two axle trailer behind. Those sombitches would hit a triple railroad track at the speed of light and it sounded like the tools in back were about to launch into orbit. There was one particular set of railroad tracks in our industrial park that had like 6 and then another 6 50 yards up. The only way they didn't vaporize was to hit the first set at enough speed to hop the rest.

Man I am so glad I don't have to deal with that bullshite anymore.

I had an 01 4.6. I sold it with 235k miles on it and owned it for 3 years. The only problem I ever had was the coil packs. After buying one for $60 at orielly I bought a pack of 8 on eBay for $50. I swapped out two more and gave the remainder to the new owner when I sold it.

It had trouble towing a car on a trailer and a pop-up camper, but it did both, so it's not like it can't do it. It's not a tow pig at all though...

The earlier 2V engines spat out plugs, more often the 5.4L and 6.8L ones. After 2001 the heads were updated for fully-threaded sparkplugs. The issue was mostly due to improper torque on the plugs. The early 3V engines had a two-piece sparkplug design that had the opposite issue, they became seized in the head.
