Re: how do you change u-joints
No . it is not normal to have to this as the Cross is bolted to the pinion flange with 2 small bolts for each side. The drive shaft will slide out of the rear of the gear box normally or if there is a flange there unbolt the 2 halves of the flange and remove it . Some diff pinions have the same arrangement depending on the make and capacity of the diff and torque requirements

check suspension rubbers and ball joints especially on the drive line end ( front drive --cv joints, ball joints , steering rod ends etc
rear end drive check for suspension movement that is allowing the drive line to change and causing problems with the "U" joints angles
firt you will need to remove the drive shaft by un bolting it from the rear end. U joints are held in with a small clip on some, others have a cover which is bolted on over the end of the u joint. once you remove the clips or cover drive out u joint with a hammer replace with new one insert clips or cover install driveshaft greese all fittings.
This happened to me. I had rear end replaced, springs, shocks and universal joints replaced and still same issue. I dropped drive shaft and greased the slip yolk going into transmission. Problem fixed. $4 grease cost me about $1500. Dave
You need to jack the back end up and place it on jack stands. then make a paint mark on the driveshaft and the rear end yoke, so when you put it back in, it will be "match marked" to the same spot. This is for proper balance. Then just unbolt the Ujoint from the rear yoke. Be sure to wrap something around the joint o the caps don't fall off the universal joint. Once it is loose from the rear end you can slide it out of the transmission. I would suggest covering the hole in the tranny also for transport. Some transmission fluid might come out of the rear when you remove the driveshaft.
Check rear-end fluid level and play in rear pinion gear.
Check universal joints for play. If play is in pinion gear change rear end fluid and add a full bottle of LUCAS oil stabilizer, will quiet rear end noise.
thats a good start. also dont forget to chk your u-joints. while its in the air have someone put it in gear and slowly accelerate. if noise or vibration have them apply the brakes and see if problem decreases. most of the time though i have found a bad u-joint to be the problem and the only way to really chk it is to drop the rear of the drive shaft and make sure that the u-joints move freely with no slop
Change the U-joints on the rear drive shaft. They don't have to move to be bad. The bearing in the joints are rusted. Be sure to mark the yolks on your drive shaft and rear diff pinion. They are ballanced are must go back in the same way you took them apart.
With that being said, did you drop the shaft an dnot put it back in the right way? that will cause a vibration. Also, have you checked to see if there is any play in your pinion shaft?
Is this a 9" inch rear end? if so unbolt the axles from from the out side behind the brakes and pull them out, then remove the drive shaft rear u joint saddles and drop the drive shaft down, remove all the bolts from the differential carrier on the drive shaft side and drop out the rear end unit, be careful it is very heavy and the ring gear teeth can really cut u up.
