Middle drive gear oil seal

Hey guys I have a oil leak at the oil seal behind the yolk that goes in the front of the tranny. I have already got the seal coming, my question is the manual shows this as being pretty cut and dry. Is the drive shaft universal joint easy to get apart? Is this seal a pretty common problem? The repair looks fairly simple disassemble drive shaft and move out of way, un bolt yolk and remove, replace seal and reassemble. Let me know if you have any tips that might help out. Thanks, Stan

I could swear you have to unbolt the front diff to get enough movement out of the shaft to clear. If I remember right it's about a 4 hour job. Dont forget to drain the oil.

ya

dont drain the oil,undo the long front bolt on the diff and the two shorter bolts on the side of the diff,all three have a 14mm head,slide the diff down and forward,shaft slides out of the ujoint,then u have to get the clips off the universal cups and tap it to one side and then slide out the joint,then use an impact to undo it from the through shaft and carefully pull out the seal and carefully push in the new one,grease the joints and spline on the driveshaft before u put it all back together...will take about an hour,done a few of them,its commom after some hours of useage...

Also, it is common for the nut that holds the yoke on to come loose. This is often the source of oil leakage in that area. Many people have mistakenly thought they needed a new seal when it was just a loose nut. Regardless, Camshaw's directions are good.
