We had a left rear tire blow out on the way home from Fl. this spring on our B.H.. While packing our bearings, my mechanic found the outside bearing was bent and damaged to where some rollers were ready to fall out. I am real happy that he found this before it did some serious damage to my rig or to someone on the highway behind me. This is another good reason to pack the wheel bearings by hand and maybe check the outside bearing after a blow out. Thanks! Tom and Mary
