Every now and then from a dead stop i hear a slight clunk like a CV Joint is dry or failing, but I have a two piece drive shaft with a Carrier Bearing in the middle. Is this bearing pressed on or if I drop it do the ends of the shaft slip out? Is this a DIY project, I have replaced drive shafts on 4x4s in the past but this is 2 wheel drive and I have no experience with two piece drive shafts.

Als is this someting that needs to be addressed right away?
