Take it to a mechanic!
I agree with the last answer, an independent one. You replace the shaft, not the jont-not worth just doing the joint!
Changing the front CV joint on a 4-cylinder (1987) is easy. Napa sells the half-shaft with a new boot and cv joint for less than $70. It took longer to get the car jacked up, to read the manual, finding out you don't have to disconnect any of the steering parts (on the pax side) that they tell you too in the manual, and the general 1st time caution, than the actual job. If I had to change it again I think it can be done in less than a 1/2 hour.
The most difficult step is removing (not as difficult as replacing) and replacing the new shaft into the tranny. You will need to use a wooden block for the replacement (long 2X4) and large sledge. It (the replacement) will be a two man operation regardless of the tools of choice. You may find a special tool for this but to use it effectively you will need to dis-assemble more of the wheel assembly that is necessary if using the wood/sledge approach. Common sense should be applied during all stages of frustration. Good luck!
