    c-3 U-joint (hey what the @#$@?

    At this time the new U-joint project has stumbled to a stop. The book says, remove carrier front bolt, nut, large washer, and cushions. Now remove forward through bolt and loosen aft through bolt. Now that went real easy. The next step is to push carrier bracket down and away. This is where easy takes a hike. First the carrier bracket can't be pushed down, cause it hits on the carrier housing. So try to remove bracket completely, but wait the aft through bolt hits the floor molding. As if that wasn't enough, measure to area between the frame cross member and the carrier yoke. Now you see that even could you get the bracket off, you can't slide the propellor shaft out that way. If you haven't given up, just go ahead and remove the suspension spring assembly, and remove the carrier. Of course don't forget to remove the axle shafts and U-joints too. Ant of you out there with manuals were written by people who actually do the work. Thanks for listening.

    Are you taking the drive shaft out?

        I just replaced the u-joints on my C2 with a C3 ['74] frame. My car had been assembled with a pass car front yoke. Corvette front yokes have removable straps on the front yoke [like the rear] so you can remove the driveshaft. I had to cut my front yoke with a zip wheel [or remove the rear end]. I did not have to remove the front diff support, the rear u-joint bolts are a bit tight to get at, the shaft slid right out and right in.

            That's what happens when they hire technical writers with English degrees instead of with technical experience.

            This is why you used to find so many Corvettes with the tunnels cut and holes into the storage compartments.

            I just checked my '63 and surprise, the storage compartment has a hole in the side of it. I checked the '79 and the bolts are below the bottom of the storage compartments.

            You can remove the clamps for the rear u-joint without removing the bracket, although it isn't easy. Then you disconnect at the front like others have said, pull the driveshaft out the front, and replace the u-joints.

            If you have a passenger yoke in the front (never could understand how so many got those), you have a problem. You might be able to drop the rear end by removing the two crossmember bolts and prying it off and then you can take the driveshaft out the back. You only need to drop the rear a few inches, not take it completely out, so you can disconnect the spring ends at the trailing arms and leave the spring on the rear and everything else connected. Then slide the rear end back into place.

            Then buy a CORVETTE transmission yoke and reinstall the driveshaft.

                Assuming that you have the Corvette type front yoke, it is relatively easy to remove the driveshaft. Just use a slim 1/2 inch box in wrench to remove the U-bolt nuts. Slide the front yoke forward and slide the shaft out forward. You do not have to remove any rear end parts. Put the box end on and use the wheel for some leverage on the nuts.

                    Now this is why I'm a member. Thank you all for the time and trouble to bring light to the subject. I have had nothing but trouble when going by the book, but you people always think like technicians. Thanks again and may God bless you and yours.
