I'm constantly having problems with those clamps.
Just found that the one I fixed last week came back off. And I bought the tools to get them tight, both the pull and bend kind and the crimp kind. I think the main problem is getting it all clean enough so the clamp wont slip off from the grease. (I thought I did)
Thought about a hose clamp but didn't think it would clear on the outside CV joint, which is where I have the most problems.
Are there "lower profile" clamps maybe....proly not...?
I was just gonna put two new axles in with factory tightened clamps.
Looks like I may have to look back into hose clamps. My subie never gets over 55 (most of it's life is spent in lo-range in the dirt) so I don't think balance will be too much of a problem. But the problem is all the dirt getting into my "CO" (constantly opening) joints.
