Hello, looks like a good bunch of information here. I'm hoping to get a couple ideas on what issues to look for first on this new to me truck. I bought an 04 Titan SE with 84k. The truck runs really well and it feels like brand new power under the hood. There are a couple lights on the dash though. Service engine light. Brake light. Slip light. I'm having the codes pulled asap. My only real concern is the limited slip or whatever kind of rear end it is. I have no experience with any type of push button locker at all. If that's even what it is. Will the code reader explain that? I did notice the what seems to be common seal leak at the axle. On one side. Anyway. The slip setting remains at I think "slip off" when I press/depress the button. What's the cost/damage associated with that. Worst case scenario? Thanks for any help.
