    I've run into some difficutly (called my stupidity) in removing the u joints. I have the rear drive shaft off, and have swapped the rear u-joint no problem, but how do you get the front u joint (on the rear driveshaft) out? /forums/images/graemlins/k5.gif

    Look for snap rings on the inside instead of the outside. Good Luck.

    You really should get a u-joint tool. It looks like a beefy C-clamp that pushes the bearing retainers out. You can use a large C-clamp and a socket (slightly smaller socket than the retainers) and it will work, but it's a little frustrating to get everything lined up. Harbor Freight has a not-so-costly u-joint tool that works fine. Look at the article "packing for the trail" on this website for a picture of the u-joint tool.

    Be sure to spray it down with some penetrant and let it soak and that will also help. The tool also helps you install the new u-joints.

    I've always done it with a socket and a hammer. I can usually do it in like 15 minutes on my tailgate. Although I've never had to replace the style with the enternal c-clips. I can't imagine it would be much different though. Here's how I do it--Remove the clips. Place a socket on the end of the u-joint cap and pound the u-joint all the way till it won't go any further. Somethimes I get lucky and the opposite cap will fall out. If this doesnt happen, flip the driverline over and knock the u-joint back the other way by hammering on the body of the joint itself, or the part that slips inside the cap. (DONT do ths if you are reusing the u-joint). Eventually this will move the cap far enuff out of the yoke that you can get the u-joint out. When the joint itself comes out, the caps are easy enuf to remove. I don't know if that made any sense......Hopefully ya get the idea. /forums/images/graemlins/confused.gif /forums/images/graemlins/rotfl.gif
