So I finally got the brakes all redone. It still doesn't stop very well, but at least it doesn't lock up and leave me in the middle of an intersection. At any rate, the driveshaft is squeaking like CRAZY. I assume the squeaking means bad news and that it needs some help. I've never done a driveshaft repair, so I'm not really sure what that entails. Any recommendations from the group? Is there a step-by-step somewhere?
squeaky driveshaft!

Hi Mike.,
You're having too much fun...!!
I've not heard of a dr. shaft squeaking.... they can rumble/vibrate/growl, etc.
So., Let's be sure where it's (squeak) coming from. What exactly led you to the dr. shaft.?
I would be more suspicious of the T-case output shaft., the rear-end., or even an axle....(assume we're talking 'bout the rear dr. shaft)
You can put your rig on jack stands & run it to isolate the source BUT., DO NOT get under any rig running in gear on stands..!! (A shop lift would be much better)
You can remove the dr. shaft (4 bolts on ea. end) & see if the noise stays or goes.
HOWEVER., it's poss. a squeak could develop in the double u-jointed CV joint.
You can re-build these dr. shafts at home but it's a bit tricky...especially the CV joint.

Was the truck sitting for some time? I have encountered U-Joints squeeking when they became dry.
Do as Bully said, then check if the joints have zerk fittings for grease. If they do it could just be a shot of grease they need.
Good luck
PS: what was the cure for the brake lock up problem.

i will have to check to see exactly where the squeak is coming from. it is definitely NOT engine-related b/c it squeaks even when the engine's in neutral and the truck is gliding. the squeak gets slower when the truck goes slower as well, so it has some relation to the vehicle and/or rotational velocity. I had it on a rack and hit all the fittings with grease but that didn't do the trick. as an interesting aside, i drove it some ways (ie - 30mi or so) at 50-60 mph over the weekend and after driving at that speed for duration, the squeak goes away temporarily but seems to come back. it very well may be one of the CV joints or something, or could even be in the rear end.
the fix for the brakes was basically just replacing a bunch of stuff. needed new drums on the front, refinished the drums in the back, and new shoes all around. also, the hubs and front-end bearings were shot, so we replaced all those as well. it drives much nicer now but still pulls pretty hard to the left when you slam on the brakes. it takes a lot to stop the truck, i think discs are definitely in the future somewhere, but not a huge priority at this point. i was much more concerned about safety (ie - not ending up in the middle of intersections b/c the brakes locked up) than anything else.

hmmm... i was thinking... couldn't i also determine if the (rear) driveshaft is the culprit by taking it off and driving around the block in 4WD on the front driveshaft only? i don't imagine i'd do any damage just going around the block on the front driveshaft only, right?

That sounds like a logical idea.
Did the squeek come after doing the brakes? I have encountered the secondary grease seal. ( mud seal) rubbing on the hub and squeeling at low to moderate speeds. It seemed that at highway speeds it expanded a little with centrifical force, or maybe got a little lubrication from the grease and was quiet for awhile, then the squeek came back. I had to trim about 1/16 inch off the outer most shoulder of the seal.
Let us know what you find. It will help others in the future.

the squeak was there all along, so it's not from the brake job. it is also not a "constant" squeak, meaning it's on only one side of whatever is squeaking (ie - squeak, pause, squeak, pause, repeat). the amount of time between squeaks reduces as you go faster and vice versa when you go slower. it would seem logical that it could be one of the the CV joints, perhaps one of the four "joints" that stick out... hence the intermittent noise. i really thought maybe a longer trip would wear down whatever was squeaking, in that maybe it was off-shape or something. we'll see. i will keep you posted when i find out what it is...

Take a look/listen to the rear outer axle bearings.

i saw that, but i was thinking on a rack or jack stands or something. i'm not sure i can duplicate at that revolution speed. also, my jack-stands are pretty crappy so i'm not 100% sure they'll hold up under motion.
You asked about driving around a ways with just the front dr. shaft on.
On a "rack" or on the street won't hurt a thing.

well, the squeaky driveshaft is fixed. as i fix things, the squeaks go away and i find new ones... imagine that!
at any rate, replaced the u-joint and greased the shaft and seems to be running pretty smooth now. i'll post the next problem as a new post...
