This behavior is by design, it is not a problem even though it may be annoying. |

This must be another 'better idea'. Oh, well. Other than that (and the other standard issues this series has had), this is one great truck: rides great, good fuel mileage, tows anything, goes anywhere. Thanks for the response! |

I've got a 99 Sierra with a couple of annoying problems the dealership has totally ignored. Has anyone had: 1) A creaking or growning sound in the front end when making sharp turns?? This problem didn't start until I hit bout 20k. Everytime I back out of the drivewy, the front end lets loose a "somethings binding" type groan. The classic dealership diagnosis was "dirty PS fluid". 2) Erratic Fuel Level Mesurement?? Once again, not something that started until several thousand miles were logged. I can put gas in and get one reading. When I get home, it can be reading an 1/8th of tank different. Depending on gas sloshing in the tank, I've seen the gage needle travel a 1/4 tank back and forth. A low fuel gas slosh has occasionally set the "Low Fuel" light blinking off and on. The dealer response: The tech sat in 2 new Sierra's and noticed different gas level readings each time he started them, so there is no problem. End of diagnosis.

| I've been reading all the Sierra info. and wondered if anyone has any firsthand experience with the new Sierra c-3? The 6.0 sounds great but would like to know if the all wheel drive feature is as good as it looks on paper. Any comments? | |

I have a 1997 GMC Sierra purchased New in 97. It is a Regular Cab, Short bed. V6, automatic. It was bought because I wanted something safe. This thing has had what I think are alot of problems in it's 3 year, 29,000 mile life. Here are some of the things replaced, most went bad before 20,000 miles:
Power Steering Pump
I took the truck thru arbitration, the arbitrator sided with GM, deciding it did not have "4 repairs on the same item"). The most irratating is a noise in the front end that started after I had the wheel bearings re-packed. A click noise everytime it goes in a driveway, or over a bump. Not as bad since the cold weather hit, but annoying just the same. It also has a problem with the rear brakes staying "adjusted" (I had the brakes checked last week, it still has over 60 percent of the front linnings left, and over 90 percent in the rear). Fuel Milage in town is about 13 in the summer, 18 on the highway (60 to 65 mph). In cooler weather it's about 15 city, 20 to 23 highway). I do not lead-foot it, and have "baby'd" it since new, which is why I worry about how it would preform if used normally. Am I expecting too much from a new vechile? My old 74 Pinto did not have half the problems of this truck (for that matter I don't recall having any vehicle with this many problems, except for a 78 Subru Brat with an un-fixable 4 speed).
Any info would be welcomed. You can e-mail direct at dkacy |

copy/pasted for jlflemmons: #19 of 19: Erratic Fuel Measurement (jlflemmons) Fri 15 Dec '00 (01:01 PM) I repaired a Suburban with the same problem. The baffle that is in the tank that keeps the fuel gauge from oscillating came loose. Unfortunately, in the Sub the baffle sloshed into the fuel pump pickup and broke it. The pump sucked up the debris and locked up. So, new pump and re-attach the baffle to the bottom of the tank. My 2k Sierra does a neat trick. When stopped long enough for the gas to quit sloshing, I can put the tranny in reverse and the gauge will drop a 1/4 tank. This isn't in the tank, but something in the gauge cluster. I will get it looked at when I put it in the shop for the typical ext cab rear door wind noise that showed up after 3k miles Jim |

Been thinking on your cold shift. True, it's a part of the transmission program. For me, it's not that noticable. Maybe I'm not paying too much attention. So, with that said, maybe it's too noticable for you. Have you taken the truck to a service center to have them update the transmission software? That might soften it up some what, make it less noticable. Just a thought. M. '00 GMC Sierra Ext cab 4dr Z71 w/ 5.3 |

I have a 99 z71 and when I use 4x4 or Auto I hear a grinding noise. Is you let off the gas it lets up a little but not that much. It is worse when you are pressing on the gas, I guess that puts more pressure on the gears. Also, if I am in 2 wheel drive and the back tires start spinning and the locking if kicks in, it slams in hard and you hear and feel a loud flunk. It shakes the truck. I am wondering is something will break sometime later on. |
