Stuff fails all the time, not a whole lot you can do about it. Things break sometimes. Just casue it could doesnt mean Im not going to use it any more or less. Like I said I have used mine for 4 winters straight and havent had a single issue.
Thats like saying "Hey if i do burn outs my tires will wear out faster but there gonna wear out anyways so im gonna keep doing burn outs" lol
I dont care what you do i was offering advice to the OP anyways
Like i said before its not a wear item that would show up after a couple years of use.. My tahoe has over 100k miles and still functions fine in 4wd but a buddies truck had 60k miles when the case had to be rebuilt...
