Hi guys I have a 2005 4.0 frontier. I had a 2.7 Tacoma before and am loving the power of the 4.0 v6. I have done a few repairs including : fix the air bag light, change to mobil 1, changed the tranny fluid and filter, broke and fixed my tailgate, power steering fluid changed and few other things. I have a whine in the front of the motor and it makes sound when I crank the steering wheel. Over all I'm happy with the extra 125 hp and torque and its a fun truck. Hope to learn from this forum and learn how to fix my issues, and improve my truck.
