How do you replace a CV axle on a 1992 dodge caravan?

For a job like this you should have a basic Haynes or Chilton book for your van.

A normal driveway mechanic should be able to do this in about 4 hours.

Set park brake. Be SAFE!!!!!!
Loosten lug nuts 1 turn on wheel to be removed.
Use breaker bar and remove axle nut.
Jack up car & support with 2 jackstands.
Remove wheel.
Remove brake caliper assy.
Use tool to remove lower ball joint mount.
Remove both sides of the sway bar retainer cap and rotate sway bar down.
Now you can swing hub assy away from end of shaft.
Remove old shaft.
Carefully support ends and slide in new shaft.
Install is reverse.
