Pictures of the Carnage
 

on the way to college yesterday I blew my rear end up.

here's the info

I pulled the diff cover off right after the symptoms started and I didn't see anything suspicious, (I was just changing the fluid and checking the gears, I thought the noises it was making were coming from somewhere else)

That sucks.

Re: Pictures of the Carnage
 

damn!!!! that left a mark...

Re: Pictures of the Carnage
 

yeah, there were nasty marks on the diff cover from it coming apart!!!

anybody want to give a guess on what happened to it?????? too many one-wheeled burnouts????

Re: Pictures of the Carnage
 

if it helps your the second one Ive seen in 3 months the other one looks the same way ..the spring pin that holds the spider gear shaft broke then it was just a matter of time before it falls HALFWAY out tears up the rear cover for a second before the shaft hits the cast case ussually locking the wheels for a second until it breaks the pin off or you STOP...fast....
we reused the case and just dropped a cunk into it with a locker ..just be sure to check your backlash

I saw a truck break one when I was a kid in the late 70's or early 80's. He was going past the house, probably running 60. Sure was a heck of a skid, he ended up sideways in the road, we had to drag him into the yard with our Massey Fergason. I remember it had quite a pucker factor on that guy!

I guess I'm lucky that mine just broke, instead of locking up.

I was accelerating (rather slowly) from a stoplight and only going about 30mph when it happened. but I'm glad it broke so I could push it off the middle of the street.

Re: Pictures of the Carnage
 

I'd just put another set of used spider gears and center pin in and keep on trucking.

Re: Pictures of the Carnage
 

Agreed. If nothing made it's way into the ring and pinion gear set, put another set of spiders and center pin in, keep driving for a while until you have time/money to put in another rear end.

Re: Pictures of the Carnage
 

I've got another diff exactly the same off the '69 parts truck

but then I'll still have a weak 3.08 open diff:whine::whine:

x2 Been there, done dat.

Re: Pictures of the Carnage
 

if my truck has factory 3.07 gears, do I have 30 spline axles????

Re: Pictures of the Carnage
 

It's a 30 splines. Looks like water mixed with gear oil to me. Was that rear submerge in water?

It could have been at one time, I live out in the country
