2004 GMC Sierra chirping noise by mundyje

I have a 04 GMC Sierra Z71 with 75,000that has been having a chirping noise coming from both the front tires when I hit subtle bumps in the road. This has been going on for about 10 months but just have never got around to trying to fix it. About 5 months ago I had to replace the front left wheel bearing and thought this would take care of the problem,but it didn't. I replaced both the front shocks and still no luck. The problems only occurs when I'm riding on roads that have not been paved in a while or on gravel roads. It seems to only occur when the front tires are being "vibrated" by the road. I thought it might be an isolated problem with just my truck, but I heard a truck similar to mine driving down the road and it had the same exact "chirp". Any help would be great.

When was the last time that the truck was greased?

Actually, it was about a week ago because I thought it may be the joints needed greasing, but still there is that same "chirp" sound.

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?

2000 Silverado 4x4 front end by kbex

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.

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.

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!

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.

Engine tapping 4.8L V8 by dougwalker

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

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
