Hows it going everybody, and thanks for looking! I have A 98 Navigator/4wd with 49k on it and im trying to fix it so I can sell it. Heres a run down of the problems.

1. The front driver abs speed sensor. How hard to fix?

2. I just noticed a small quarter-sized stain under the truck. It looks like red fluid. Im guessing trans fluid. Is there problem areas for trans leaking?

3. The drivers door. The unlock/lock button doesnt work all the time. Is it just the switch?

4. There is a humming noise coming from this box thats next to the abs module on the driver side under the hood. It seems to have a cable that runs to the throttle body. It only hums when idling. What is this box thingy?



Thats it for now, other than these problems its perfect. I'd like to sell it in great shape if I can. Any help is greatly appreciated. God Bless
