Not really sure about that. I don't know if somehow that would put more stress on the weaker one or if that matters since they are independant being all wheel drive. I also have had the thought that the cv being tougher might transmit more forces on the diff. However it might also be able to withstand the forces better than the cv's. I have thought a lot about this. For now I just carry a couple of extra CV's
I have not had a problem with my CV's,,,,,yet so I'm still on the fence.
I guess it's like me having the BP tie rods made since that was definitely a weak link but most people just carry a stack of spare OEM. It seems people that have had an H3 for awhile have adjusted their driving habits since all the broken tie rod stories. It still happens but you don't hear about as many.
The boots would be a nice up grade though and that can of course be done as needed. I should probably have a set of those on hand.
To be honest I have removed my steering knuckles to replace them for the one I already had drilled out for the BP tie rods but I have not replaced a boot.
So I have been down to just before pulling one out but did not have to. Looking at an extra cv I'm wondering what is involved to do that. It appears you would have to take the ends off because of the smaller end being inboard on the shaft will not go over the outer end. I need to read up on that.
It' really fun! This is mine.
Here is a link to some gory pictures! I think I would just replace the whole thing then worry about replacing the boot on the one I took out, later.http://www.google.com/search?q=cv+shaft ... 80&bih=598
