Question about GMC Cars & Trucks
Original intermediate shaft had no lock ring. Used same shaft and it seemed to go into the replacement diff further. Do not know what replacement unit came out of.

SOURCE: four wheel won't engage
Theres a vacume dash pot under the battery box. It pulls a cable that engages the front diff. Put the vacume line and you'll have lights and four wheel drive. (it happened to my blazzer)

I am assuming this is an all wheel drive. That being the case you probably have an axle CV joint going out. If you hear noise when making a sharp left or right turn and accelerating that would more than likely be the problem. And, yes this is a serviceable part. Easy to replace if you have the proper tools to accomplish the task. Good luck.

I had the same thing happen. The automatic locking hubs are faulty, causing one or both hubs to try to engage or disengage onto the front driveshaft. This makes the clicking noise and loud clunking that you hear. You may notice your steering pulling to one side of the road,because one hub is locked in. Replace the automatic hubs with new ones, do not try to fix the old ones. I liked the
convience of automatic hubs but replaced mine with manual hubs, there just way more reliable.

SOURCE: how to replace front cv shafts ?
remove inner cv boot, just on inside edge is circlip which holds inner bearing joint into outer housing remove circlip and separate joint outer housing does not come out of front diff unless you drop or remove whole front diff assembly
will have to remove whole stub axle hub assembly to remove drive shaft from outer wheel stub axle (hub) assembly
