2003 Sierra 1500 grease fittings

I'm going to start changing my own oil on my truck and was wondering if someone could tell me exactly where all the grease fittings were located underneath.

Thanks.

Probally does not have any if the suspension parts are original.Check your transfercase and both differantals if it is a 4x4 also.Checking the fluids is a must during an oil change and most oil change places do not do this.I have seen this,a burned up transmission and a burned up rear end so far because the oil change place and one dealer did not do this.The transfer case uses special fluid if it is a 4x4,Auto Trak II and it is from the dealer only.

There are fitting, upper and lower ball joints (4), tie rods (2), pitman arm (1) with fitting facing up (pita the get to) and the ldler arm (1). I think I covered them all. No wait, I think there is one on the front drive shaft of 4x4's.
