I just swapped in a HP30 axle that has 4.56 gears and a LockRight. I am currently running without a front driveshaft since the rear is still 3.55. When first driving the jeep, there is no noise. When I get up to highway speed and then slow down (like on the offramp) I have a very noticeable noise coming from the front diff. As I slow down, the noise starts somewhere between 30 - 40mph and from then on I hear the noise constanly when driving at that speed or less. I'm using Mobil 1 synthetic gear lube which is a 75-90 weight. The previous owner did not have these noises so I'm thinking maybe I did something to it when I removed the carrier to inspect the axle seals. But I am sure I put everything back in the way it came out.
I can live with the noise but I am worried that the diff might grenade on me sometime in the future. Is gear noise a sure sign of iminent failure?
I also was planning on doing a manual hub conversion later in the year or next winter. Ideally if I could do this now, the gear issue would not be an issue on the street and wheeling is at slow speeds, so would I still need to be concerned about this? (diff grenading on the trail, is just as bad ($$$) as if it grenades on the street...)
Any advice would be much appreciated.
