Here is everyones nitemare!

Got a 99 CC LB 7.3 4x4 in and what a sight it is. Not a bad looking truck, well taken care of and good looking rims and tires. But there was a small problem. The customer was driving down the road and the front drive shaft blew the front u joint ( why it was spinning I don't know) and guess what happend next! The drive shaft dug into the highway, blew the transfer case in half and tore it off the transmission. Cracked the transmission case in half and then proceeded to put a hole right through the floor. On it's way out it took all the fuel lines, electrical harnesses and everything else in the way. Thank god for insurane, because they said they were going to cover it. Sounds like fun. Thought you would enjoy this.

That make for a really bad day.

probably spinning cuz the dork had the hub's locked. and yes...

ive seen this before jon, and it wasnt the u joint or double cardigan joint on the driveline tht failed, the T case had a bearing lock up. Id put money on it that is what happened. Saw one that actualy broke the trans partially in front of the crossmember and wedged the trans case inbetween the crossmember, i didnt work on that one but it looked like a nightnmare....

Moral of this story is dont neglect your T case. I reccomend servicing every 30k, but at max service every 60k

since were on the subject of maintaining the T-case and some dont have their owner's manual's, how should you service the T-case and the diffrential's? oil?

10mm allen wrench or socket for the t case. It takes standard mercon....or mercon 5 will work as well. Standard mercon is being phased out since merc 5 has been proven to work for both applications. just pull both plugs with a drain pan under the t case, let it drain all the way out, put the lower plug back in, and fill it till it comes back out the upper hole

The diffs require cover removal and resealed but are the same fill procedure. 75-140 synthetic in the rear and 80-90 in the front

If you're not willing to do that, then get a shaft saver loop like the pullers have.....

I have seen some pics of those and wondered...what they are and what do they do?

[99Smokin73Stroker]

A common failure in pulling trucks is shafts and u-joints.....since they are turning huge RPM's they'd rather not have any of their shafts spinning and smacking whatever the heck it wants underneath......and now you know!
