Well I'v decided to get outside and work on my blazer today seening its good weather and all. I'm working on my back brake cylinder, I gota replace it on my driver side. Anyways I was thinking, When I replaced my cv axle months back I drove around with out one in place on the driver side. When I went to put the new one in it I noticed that the seal for my bearings poped off the back, I checked the bearings and snugged it back into place. Long story short is it bad that the seal poped off the back and should I maybe replace it?

 

If you already have it apart, now's the time to replace it. Check your front diff oil also.
