This problem is not unique to you. There is still a lot of stuff out there
of poor quality being reboxed in many different brands. One thing that helps
is proper installation and packing of the grease. A properly packed joint
will NOT have any grease in or on the boot. After install the boot needs to
be vented so that it is not under vacuum or pressure.

Subject: Cv boots cracking

I've only driven my Syncro for a year. It took over a year toget it ready
and I'm not sure at which point I rebuilt my rear half shafts. At best,
they're only two years and about 10,000 miles old but I'm finding that
several of the boots are already cracking significantly. These where Rhein
boot kits purchased from ken willford.
What could cause this aggressive decay and how can I prevent it?
