2011 dual cab, no lift, losing cv axles. Why .

Last Dec, I came here asking about CVA replacement. I bought NAPA parts and had them installed by our local mechanic, who had just finish installing new struts and shocks on the truck. I lost the left side the last of Feb. and the right side this summer. I have not done any heavy rock crawling, but do drive some greasy clay roads in 4 wheel drive on foothills of the Big Horn Mountains. I can only think of one time that the right front wheel was off the ground when I slid off the edge of the bypass of a bad water problem in the unmaintained County road and tried to drive around it, slid off the bank and got high centered with right front being off the ground while used by come along to extract my self . But surely that should not have caused the cva to pop out. If it did what do we have wrong, your thoughts please.
