any suggestions on how to repair a torn rear CV boot. I am sure I caught it early enough to replace the boot it rather than replace the axle. suggestions would be appreciated

Find which one works for you.

if it's the outer joint, you can't do it. it has a crimped on metal band that needs a 700usd crimper to install. the inner is typical cv joint. good luck, chuck.

It is the inner one (closest to differential). I did not realize the band of the outer joint boot is different from the inner one. They look the same.
