U joints
- Thread starter BIGBlack87K5

Need more info. Bad u joints normally make a noise or vibration, not violent shaking.
U-joints are basic for the rear if you have a bench vice.
I prefer Spicer u-joints, but when I replaced mine over the weekend 4 wheel parts had given me the wrong type. I went to pep-boys and got those Neapco Brute Force u-joints instead as I've heard good things, and all is well.
My truck drives and feels like new right now. Better savor the flavor.

The best u-joints I found are Spicer Life series. Most auto parts stores do not carry them. Driveline shops should have them.

There was a thud if that helps
Get underneath the truck and grab some shaft. Shake it around a bit.
In particular, grab the driveshaft and the slip yolk, and see if there's any play between the two.
Really, U-joints in the rear are easy enough to replace just on good measure alone if you've never done them. It's funny, because even a slight walk in a u-joint will equal a number of weird conditions the truck may exhibit when it's under it's weight and driving down the road.

Thanks for all the help guys
CHOCK THE WHEELS!!!
If the truck is in gear, or park, and you remove the rear drive-shaft, its free to roll!
I had a guy who asked to borrow a prybar to get the shaft loose on his Cameo.
He said he had the clamps loose, but the bearing caps were stuck in the yoke.
I wandered over, found the car backed up a steep incline to get more clearance, in park, and his head was wedged in front of the rear tire as he tried to prise the bearing caps out of the rear end yoke.
Fortunately for him, there was so much load on the shaft he could not get it loose before I stopped him.
I mean, the rear end of the car was up at about a 45 degree angle. it would have rolled over his head without even slowing down!
Worst part was, I told him, the side of my car was just across the parking lot from the front end of his.
It would have crunched the whole door in........

replace all the u-joints in the shaft at the same time it's better that way also you might have a bigger joint near the trans if you do its either s44 or 1350 a k20 would have them in the computer most places

are these good u joints http://www.northernautoparts.com/ProductModelDetail.cfm?ProductModelId=16655
Those u-joints are badass. A good rule of thumb for u-joints is that Spicer's are generally the best.
Make sure you don't have a c-clip type ujoint. I bought the outside snapring type like you posted, but my '91 used the inside c clip style. Go look and see if there's a snapring on the outside of all the cups.
