#57 of 172 Re: 2004 GMC Sierra chirping noise [mundyje] by davethecarnut Jun 06, 2007 (9:59 pm)
Replying to: mundyje (Jun 05, 2007 7:14 am) Is the chirp coming from the tires or the suspension components? If it's tires, maybe the tires are getting "air" and chirp when hitting the pavement over those bumps. I don't know. Just offering suggestions.   You have zirk fittings on the 1500 other than the steering linkage?
#58 of 172 2000 Silverado 4x4 front end by kbex Jul 05, 2007 (8:19 am)
I'm getting a clunking/popping sound from the front end while driving in reverse and straightening out the wheels. It happens when steering from right to left. I've checked underneath, there isn't anything loose or rubbing that I can see.

Replying to: kbex (Jul 05, 2007 8:19 am) Sounds like it could be a loose crossmember. They will usually bind when reversing for some reason. I had the same problem. Just loosen all the bolts and retighten according to spec. It's usually the one under the trans.

Replying to: obyone (Jul 05, 2007 8:41 am) I finally got around to looking for the problem, and re-tightened the crossmember bolts, but it still does the "popping" thing when going in reverse. I'll keep looking, thanks for the info! Replies to this message: obyone (Aug 12, 2007 5:06 pm) kbex (Sep 30, 2007 9:22 am)

Replying to: kbex (Aug 12, 2007 12:54 pm) When I had a friend's shop tighten the crossmember with an impact gun, I still had the popping. The correct procedure is to loosen all the crossmember bolts then tighten. Can't remember the torque settings. Replies to this message: kbex (Sep 30, 2007 9:22 am)
#62 of 172 Engine tapping 4.8L V8 by dougwalker Aug 14, 2007 (9:09 am)
My 2002 Sierra SLE with the 4.8L V8 has an engine noise that has been going on for a few years. Sounds like lifters to me. Was told by the dealership that it is normal and will not harm the engine. It only rattles for a moment when accelerating a little on the fast side. Does anyone have the same problem or know of a fix? Thanks

Replying to: gumpp08 (Apr 17, 2006 5:08 pm) Gumpp08. I have an 03 gmc 1500 crew cab with a 6.0 engine. It makes a noise like the lifter pecking really bad when you start it and you can still hear all day long when its under a load. I have had it to two shops and they say its normal. if it is I will not buy another one as its driving me up the wall. Does anyone know if it is normal for these engines to do that even after they are warm. I dont trust either shop as the dealer has connections with both of them. thanks Replies to this message: bjandpeggy (Oct 11, 2007 5:32 pm)
#64 of 172 Re: 2000 Silverado -VIOLENT SHAKING [cappy8] by bigbeca Sep 04, 2007 (11:26 am)
Replying to: cappy8 (May 22, 2007 8:19 pm) We have a 2000 Sierra 1500 that also "shakes violently", similar to the Silverado description. The shaking occurs immediatley upon driving over an overpass expansion joint or similar ridge on the road and results in a violent shake/bounce in the front-end and steering wheel. The shaking doesn't stop until we bring the truck to a complete stop on the side of the road (slowing down doesn't help once the violent shaking starts - a complete stop is required). We have taken the truck for "repair work" several times but nothing has fixed this problem - we have replaced shocks, wheel bearings, tire rods and rotated tires without any improvement. We no longer trust our truck on the highway and currently use it for short, side-road trips at low speeds only. Any suggestions?? Replies to this message: obyone (Sep 04, 2007 5:06 pm)

Replying to: bigbeca (Sep 04, 2007 11:26 am) Has it gotten worse or remained the same over the last 8 years?
#66 of 172 Driveline Vibration? by xbbuster Sep 21, 2007 (7:15 am)
I have an '07 Silverado Classic ext cab W/T. When the transmission shifts at 40-45 mph there is a brief vibration or shudder that can be felt in the steering wheel and gas pedal. When I took the truck in for it's first oil change I mentioned the problem to the dealer's greeter. When I picked the truck up I was told that the transmission was operating as designed. They did not road test the truck, just plugged it into a computer. Could this shudder be caused be the two piece drive shaft?
