Cross Pin Seizing w/ Wheel Spin?

[MunkeyTX]

I sirched, and didn't find nothing so here goes...

In the beginning of the year, the little bolt that holds the cross pin in my differential broke, letting the pin wiggle out & caused damage to the spiders and carrier. Chalked it up to wear, tear, and some heavy right footing. Shop replaced broken parts and I was on my way.

Well this last Saturday, right before heading out on the road for Memorial Day, I was turning into my driveway, the rear end starts to clank and buck like a bitch. Going straight, everything is fine, but any slight turn and she's clanking and bucking. I figured something in the install of the previous parts had failed, since it's only happening when turning (spiders, etc.). Parts have a warranty on them so I wasn't overly concerned about the repairs.

I had the truck towed to the shop yesterday morning, and got the callback yesterday afternoon. Shop said the cross pin had seized due to excessive tire spin. The tech said he even took pictures of the pin and shot them off to his gear vendor because he hadn't seen anything quite like that before. Gear vendor told him it was either a lack of lubrication (had plenty of fluid, I checked myself before having it towed), or excessive tire spin. The truck is my wifes daily driver, and we haven't used the truck in any capacity that would cause tire spin.

I've had other vehicles that I've spun the living shit out of the tires both on and off road, but never had a problem (besides a twisted shaft or two, or three, and some bald ass tires ).

Is the shop throwing me a line, or does this chit really happen?

Edit: Guess I should mention, '02 F-250, 10.5 Sterling/Visteon/Ford/Whateverthefuckyouwannacallit rear end

yes it does happen. when you spin the 1 wheel it flings all the oil away from the x-pin shaft lube area this will cause the pinion spiders to seize onto the shaft.

I don't doubt that its possible..but the excessive tire spin they are describing would be and incredible amount..and it should be readily noticeable because one of your rear tires should be worn bald.

Shop is putting in an Eaton Posi since they'll have everything apart...that'll teach the wife when she goes sliding into a ditch.

Got the truck back from the shop a few days ago, rear end is nice and tight. Even had an 'oh shit!' moment when I mashed the pedal whilst doing around 30mph and had the ass end slide out from me (rain slicked road).

I was looking at the invoice, and it lists the part number as DAN73109X, which according to Randy's is Ford's TracLoc.

Dang it. My truck was OEM with the TracLoc, and I wasn't too impressed with it's performance.

I was only tagged by the shop $400 for it, and the Eaton unit lists for a good $200 more than the TracLoc. SO, until I pull the cover off to change the fluid, I'm guessing I've got a TracLoc.
