    Replacing front bearings, anything else to do?

    @Doubeleive I thought about that. Do you just pop off the cap that covers the axle nut? Frankly, I need a bigger breaker bar. For now, I gave up on driver side and reassembled everthing. The driver sides actually seems pretty tight. I will keep an eye on it. I also needed the truck and thought...

    Replacing front bearings, anything else to do?

    By the way, When noise started happening from time to time. we brought it to the GMC dealer in Ohio. They took if for a drive, lifted it, checked it out. Then told us they could not replicate the noise and everything seemed fine. And since they could not find anything, they did not charge us...

    Replacing front bearings, anything else to do?

    I am in the process of replacing front bearings on my 2004 z71 tahoe with about 145,000 miles. I replaced one side that was so far gone that when I lifted front end, i could shake wheel. Very scary. Doing the other side now but having problems getting axle nut Off. Will work on that later...

    Changing coolant in a 2004 Tahoe z71 with rear heat

    I don't think there ever is a good time for a breakdown. I have been lucky and they have often been on nice days. The Tahoe has not yet broken down on us though...

    Changing coolant in a 2004 Tahoe z71 with rear heat

    my thought on this is that when hoses get old, they get hard. So under vacuum, they would most likely fail if under vacuum (since usually under pressure). If they fail, I would rather them fail while i am in the garage changing the coolant than on the open road.

    I am good there, too many actually. I have two oil compressors, one portable. 30 and 80 gallon more or less. Intent was to run them at same time if I needed the CFM, sand blasting or other. but usually only use the small one.

    Plus it is just another excuse to buy a cool tool.

    Yeah, What he said :) I had a VW once that I drained the fluid and had a hell of a time getting rid of the air. Figured this was the way to go. When you consider the cost of doing it at a garage, it paid for itself already. Plus you can use it to test radiators (off vehicle) etc.

    Correct. Hooks up to your compressor to make vacuum by creating a venturi effect. The device connects to the expansion tank (or radiator if you have older vehicle) and a screw expands the rubber gasket to make the seal. You would need a compressor.

    Changing coolant in a 2004 Tahoe z71 with rear heat

    Did it Saturday. It took forever to get the damn clamp off the lower radiator hose. It is a big one. Luckily I had bought a tool that keeps it open for duration of the operation. I did not know about water pump hoses. Keep that for next time. But the coolant was nice a clean coming out. I only...

    Changing coolant in a 2004 Tahoe z71 with rear heat

    I remember it is better to lift the rear of the truck to drain?

    Changing coolant in a 2004 Tahoe z71 with rear heat

    Ok. Thanks. I thought there may be some mechanical valves that would prevent the draining of the cores.

    Changing coolant in a 2004 Tahoe z71 with rear heat

    Hi have to change the coolant in a 2004 Tahoe z71 with rear heat. In order to properly drain the truck, do i need to do anything to open up valves for heater core (front and rear) prior or during draining? The FSM says to pull the lower radiator hose off radiator. I have also seen posts about a...

    Trouble shooting P0171 P0174 Bank 1 and 2 too lean

    The circled area is where I heard what sounded like a vacuum leak. Again the propane did not have a noticeable change in RPm. Is this normal? I saw someone use water to locate vacuum leaked. I may try this next.
