    99 denali onstar phone

    So here's the phone photo. I guess it was a dealer installed option. Also has a stubby antenna for the phone on the passenger side cargo area window. Kind of makes me think of the maxwell smart shoe phone. Anyway I've decided not to mess with it. I was considering installing a double din unit...

    99 denali onstar phone

    My 99 denali has the old fashioned corded phone installed in the center console. I want to remove it since it's useless and takes up a lot of space. I've tugged on the cable where it goes into the side of the console but it doesn't want to come loose. Is that a connector that can be unplugged...

    Looking at a 2004 EXT

    Would like to hear from EXT owners about your experience regarding problems to look for. Specifically automatic rear suspension, transmission and general reliability. I had a 2002 avalanche 5.3 that was just okay I remember it was kind of squirrelly in a strong cross wind I think because of the...

    Turn signal & brake light problems

    Just to close the conversation, the problem turned out to be the bulb mounting plastic plate. Got a new one from Amazon, $7. Tip, use a magnetized screw driver to remove the screws that hold the taillight assembly to the body

    Horsepower gains?

    Yeah I know I had a 07 duramax but sold it when I sold my travel trailer. Thought the Yukon would be okay for towing the boat and didn't need a truck.

    Horsepower gains?

    3.73 posi gear. Yes it hunts gears. No pull below 3000 rpm on long grades. Shifts down to 2nd gear which winds rpms to around 4500 which makes me nervous. Non towing performance is ok for such a heavy vehicle. Engine seems to be good, no oil consumption. Transmission was rebuilt about 5k miles...

    tires question

    Just to close the loop on this thread, Today I went with a set of four P265-70-16's. Decided the softer ride was most important to me and wow what a difference, better than hoped for. I only tow my ski boat a few times a year and not for very long distances so I think these tires will do the...

    anyone flat tow a obs yukon 4wd ?

    I looked at the owners manual before posting the question. I just found the section covering it so obviously I didn't look closely enough. Anyway the answer is with the engine running, place the transfer case in neutral and then put key in the off position.

    tires question

    New here, just bought a '99 Yukon Denali that needs tires. Currently has LT245/75-16s on it, Tire shop shows P245/70-16 as the correct size. I don't plan on doing any off road driving. I do want to occasionally tow a 3500 lb. ski boat. Which is the better choice? It doesn't seem to me...
