Anyone know why my universal joint on my snowblower will blow out the clip and little cap with pin bearings.This has happened 4 times now and its starting to piss me off. I haven't changed the universal joint because the new one I have is too small but the caps and pin bearing are the same. I have installed new caps but after a couple of hours of blowing snow the same cap will blow out and everything will come apart.The last time it happened, I tack welded the cap in two places.Today it blew out again. Fixed it and tacked it in 4 places.
