Jerk and bang

Well the rear end looked like you threw a grenade in with it..... Buying a rebuilt one from japser.... I think I might start crying at any moment.

sorry to hear that. I thought the 08s were supposed to be the better year of the 04-08 f150s.
How did the gear oil look? Was it thick or still in good condition?
anything you might think led up to this?

My truck is an 05. 08 is when I graduated high school. 170k plus miles and big tires and towing add up to stress on gear teeth. Kinda weird I has a rear end go before a tranny.

Yeah, everyone likes to see a blowed up diff.

I didn't take any, just imagine spider gears missing a lot of teeth.

No, we need pics. Go tear it apart and take some pics for us.

Just curious, but have you ever serviced the rear diff to make sure the fluid was full and or ever changed it since you purchased it?

Sounds familiar......happened to my daughter's Expi.I found an entire used axle at a nearby wrecking yard and swapped it in.

Yes, it was changed once with amsoil from you, then I had to change axle bearings not long ago, so I changed it again. I did find a lot of shaving and chunks of metal last time.... Just kinda bolted it back up after cleaning it out. Guess the limited slip just decided to go. Ring and pinion looked ok for 170k plus miles.
