I have this humming noise that is constant and appears to come from the front. I immediately thought wheel bearings or pinion bearing. I couldn't really tell if there was any play in the yoke, how do you check the wheel bearings ?? Jack the vehicle up, place hands at 12 and 6 position, rock tire back and forth. If it moves AT ALL you have bad wheel bearings. Didn't notice any movement on either sides |

You can have flat spots in the bearings and they will feel tight, but still make noise.

The noise will be worse when the weight is on it and better when you take the weight off. Feathered tires will make this noise as well, so look at them. |

Ok I'll try that I know it's a constant noise from 5mph to 65 mph Kinda makes a noise when slowing turning too |

A lot of times you can also feel the roughness in the bearings by turning the tire or hub by hand when it's jacked up.

Didn't really feel any roughness It spun and just made the sound that came from the rotor scraping the brakes. Feathered tires.... The tires are nexen mud tires, sound only comes from Front and is constant. Doesn't go away with high speeds or if I put it in neutral and coast |

Rotating the tires took care of the noise. The tires are pretty crappy
On a side note
I'm still losing coolant and it's not in the oil. I can't seem to figure it out

You probably have a small leak in one of your hoses. It may take a hot minute to find where but that would be my guess.

I'd just sell it and start with something new. If you've had this many issues with it already you'll probably continue to have issues with it.

That's a terrible idea bob! He's come so far with it and learned so much, why stop the lesson. I mean it is a jeep and will "just empty every pocket."
I'd say start it up, let it get to temp and check things over. There are only so many places it could be coming from, start narrowing it down. Do the easy ones like MJL said, hoses. Make sure everything is tight.

Pressure test the cooLing system. Or maybe sell it and buy a jeep bicycle.

Hunter's truck kept loosing coolant and we searched and searched for it and couldn't find it for two months. It wouldn't leak on the ground, and we couldn't smell coolant. Finally I was under the hood hooking up the amp he bought from Weezie and I saw a drip out of the corner of my eye and found it. The plastic heater hose quick connector was cracked and was dripping on the exhaust turning into steam. We even pressure tested it and it wouldn't show when cold.
Is it loosing more or less than it was before you swapped the head?

Is it loosing more or less than it was before you swapped the head? Well about the same if not a little less. The oil looks new and the coolant is green. I am not noticing any spots on the ground either. Yesterday was the first day that I've had to put water in it since the head swap and it was an inch below the full line on the reservoir. |
