It was a long time ago, but I had a 700R4 in an 87 K5 go out while going through some hills. I limped in to a GM dealer to check it and they said they would have to put one in. $1400 and 2 weeks later it went out again. I took it back to my local GM dealer since the trans fell back under their warranty. After they checked it, they determined the last time it was replaced the D-Tent cable was left off. I was running a 4" lift and 35" GroungHawgs(loved those). Long story short, make sure the truck downshifts correctly and verify that cable is on. Funny part is about a week after my local GM dealer installed theirs and took care of the cable problem I got a call from the 1st GM dealer saying they under charged me by $400 dollars-20 years later, they are still waiting. I drove that Blazer hard for a long time after that and NEVER had another issue.

This small one-ton press worked great to install the new U-joints.
The factory used Loctite Red or something similar. I had to chase the threads on the five M10-1.50 threaded holes before I bolted up the right axle assembly.
The old seal on the left was egg-shaped from wear.
This is the right side axle with the gear and shim just resting on the top of the axle shaft. If you just pull the axle out without removing the axle tube this shim drops down in to the cavity shown here.
No shortcuts. You have to take it apart to get it back together properly. It's really not that bad. I took one day to take it apart and clean parts, and the next day to put it back together. I'm sure you're younger than me and could do this faster. I kind of have to pace myself at my age...;^)
