No big deal. It turned out to be a 2 hour job for 3 boots. The fourth.... Well: I replaced one last march. All others were in fine condition (then). Only two month's later i find two others cracked and thorn completely. That's why i would advise to replace both boots when taking an axle apart! You don't need to unscrew the big wheel nut! The procedure is as follows: When working on the exhaust side... lower the exhaust a few inches by unscrewing the 13mm bolts. Don't remove the exhaust. Unscrew the allen bolts carefully. Lower the axle on the transmission side. I'ts possible to lower it so that you can access the cap on the first joint. Open the clamb's that hold the boot. Use a knife to remove the boot. Take off the Cap with a screw driver. (a new one is with the new boot) Take off the 'C' clip that holds the joint. (a new one is with the new boot) Take off the joint. Apply some force with a rubber hammer if needed. Take off the wheel (dont touch the nut) to get some space to work on the boot at the wheel side. Attach the transmissionside boot on the joint part and repack with the new grease that came with the boot. Clean out if required. Move the new wheelside-boot in the correct direction on the axle. An easy way to get the boots on the axle is to cut a piece of metal from a tin and wrap it as a cone. Insert in the boot. Move the cone with the boot over the axle, and then move it far enough. Hold the metal cone, and move the boot back until it's in position. Remove the metal cone. Easy... no more struggling. Next attach the new clambs around the boot and secure tightly. Then screw everything back together and : job done. Success.

Remove all the Allen bolts (be VERY careful not to strip them) and the axle will come out. There's a clip on the end of the axle to remove and the CV should slide off the axle. I did all 4 on my '78 in half a day (taking my time too), which included taking apart and repacking all 4 CV joints. Very messy, but not very difficult. If you disassemble the joint, make sure it is "flexible" when you put it back together. If it is put back together incorrectly, it will bind. You'll see what I mean. Some listers recommend putting the joints back on in different spots to even out the wear.

I am not finding any real precise info in the archives. One local shop told me he couldn't recall but he thought you had to something extreme to do this. Any thoughts on this would be great. >> Jim, I just completed this little job last week with lots of help and guidance from Cap'n Earl Gillstrom. The replacement of the boots is pretty straight forward and if you have 2 people, it goes pretty quickly. If you are under the car, the other person can operate the parking brake to keep the axles from rotating. The left rear is a little tricky due to lack of room and you may have to drop the exhaust. I have an RMB, which gives you more room, but I still removed the bolt on the bracket that holds the intermediate muffler. Be careful not to put too much pressure on the exhaust as you don't want to stress the headers and exhaust manifold bolts. Also, if you take the wheels off, that also helps. Remove the 6 bolts on the inside where the axle attaches to the differential. Then, if you have someone helping you, have them tap the axle out of the wheel. After the assembly is out, clean it thoroughly (Earl has a kerosene bath which made this very easy), then either press or tap the inner CV joint off of the axle. We used a hammer. One came off very easily, the other had to be persuaded with many hits. I cleaned all of the old grease out of the joints (the replacement boots come with new grease), but this was easy with the bath. BE CAREFUL WHEN HANDLING THE JOINTS AS THE MAY COME APART! There have been tales of people chasing bearings across the garage floor. Next, repack the joints with grease, put on new boots and clamps and bolt them back on. We switched sides as some people have recommended this extends the life of the joints from bearing race wear. BTW, I also repaced my rear drop links with the steroid kits developed by Louie Ott and my car corners much flatter in the turns now. Good luck.

I never bothered to take the wheel nuts off. The job can easily be done from the tranny side up to the wheel if you have enough space to work under the car. Only take the wheel off to reach/secure the upper boot. Just release all bolts on the tranny side and drop the axle. You need to lower the exhaust pipe as well, but can leave it hanging. It is not too much in your way. tip: Make a small cone to slide the last boot on the axle. You will have to slide it on in reverse direction, meaning the smaller opening first. Thats the hard part !! Save you half an hour hassle..... in the grease... make a cone. Theo
