So with 205,000 miles on my 03 suburban it may be time to retire her. it seems like with the cold and snow a lot of little things have started pop up. ABS lights on, front diff or transfer case is starting to growl, O2 sensor code came on, and the engine doesn't sound the same as it used to when I start it, that may be the A/C pulley. anyway, I love the suburban, its been a great vehicle and I want to get another 03 0r 04 with a lot less miles...but as I'm looking around I'm wondering if there are any differences between the suburban and the yukon XL (not the denali). anybody got any thoughts...are the the same drivetrain, brakes, wheelbearings etc?
