I'm finally getting my hands on a 14FF. It is out of an 80 3/4 ton work truck. I know it has 3.73's but I don't know the condition. I am planning on putting 5.13's in it and running 39.5" TSL's. I was wondering what else I need to replace to get it in top condition. I was thinking new bearings and races but what else. Thanks in advance!
