So far I hadn't had any major problems with the vehicle. This is good since my initial warranty has expired and I've yet to purchase another extended on.
However, I did have a check 4WD notification due to a faulty switch. Once the switch was replaced, I've never had any other check 4WD notices.
I've also had leaking front differentials. It happened prior to my warranty expiring, so that was easily fixed.
I've been quite alert and up to date on preventative maintenance. I do all of my own basic mechanical maintenance.
Lately I've replaced my tranny fluid even though it wasn't due to a change out for another 10K miles. I change my engine oil and filter every 3K-5K miles, or when notified to do so by the computer, whichever comes first. I've added fluids to my differentials, and replaced my air-filter twice. My next preventative maintenance is changing out a fuel filter.
When it comes to engine oil, I use nothing, but synthetic oil. I also use Chevron Techron fuel injector cleaner every four gas tank fill-ups.
Vehicle runs great, and with my copy of Chilton's, I intend to keep it that way.
My 2001 Silverado 1500 2wd has a slight vibration when taking off between 15- 20 mph then it stops. Could this be low differential oil?
