    2003 Suburban Erratic Voltage Meter Readings

    Thank you for this important recommendation. I previously removed the instrument cluster last year to fix transmission display connection on the printed wiring board and ended up with the fuel the gauge and rpm needles incorrectly reinstalled. Now I can index the correct needle positions when I...

    2003 Suburban Erratic Voltage Meter Readings

    Thanks to everyone for the recommendations. The actual voltage output at the alternator has always been good. I will remove the instrument cluster, clean it with isopropyl alcohol and replace the stepper motors, which are listed on eBay.

    2003 Suburban Erratic Voltage Meter Readings

    My 120,000-mile 2003 Suburban voltage meter readings frequently indicate more than 18 volts and then the needle is pegged at maximum. Whenever this happens, which is frequently, the voltage meter needle never returns to zero when the engine is off. When the voltage meter doesn't return to...

    Intro-05 Denali Yukon shocks

    I just replaced the front and rear shocks on my 118,000-mile 2003 Suburban which had the costly ZW7 auto autoride shocks. I ordered the AC Delco rear shocks for about $41 each from Rock Auto.

    ‘07 Denali XL, should I invest?

    I would recommend installing new heater hoses and the plastic fittings at the firewall. Those can be a frequent failure on higher mileage vehicles. Our 07 Tahoe with 145K miles burst the hose at the firewall just as we were returning home, spewing coolant. If this would have happened in Dallas...

    New tahoe owner needs help please

    I recommend changing the heater hoses and plastic "T-Fittings. We have a 2007 Tahoe LTZ with 145,000 miles and the heater hose broke at the firewall plastic "T-fitting" and lost a lot of fluid as we arrived home from AML Leukemia Chemo treatment. Rock Auto has good prices for the hoses with...

    Anyone seen this electrical problem? 2003 Tahoe

    I experienced the exact issue with my 97,000 mile 2003 Suburban last fall. After checking the battery and alternator output I discovered that the alternator output was not getting to the battery. I disconnected and cleaned every electrical connection from the alternator positive post, thru the...

    07 Yukon .. vibration during light acceleration..

    When stopped, put your foot on the brake pedal, then shift from drive and back to reverse. Listen for a "clunking". If you hear a clunking then the driveshaft U-joints need replacing and causing the vibration. Hope this helps.

    I’m being told my engine is bad

    I had one of the bolts come loose that secures the torque converter to the flywheel on my 2001 Yukon several years ago. The bolt was being knocked around by the rotation of the flywheel/torque converter and it sounded exactly like your posted audio recording
