Replying to: cappy8 (May 23, 2007 7:07 pm) But you said " nothing recurred" as in it hasn't happened since that incident? That was the "new" roadway. If it was your shocks, it would happen more often. Unless you really load down your truck or drive fast over speed bumps, shocks can last 90,000 miles or more. If the truck bounces up and down too many times or there is fluid leaking out of them, then you should replace your shocks. Just my experience.

#52 of 172 Frontend Binding/Clucking Noise by 97gmc4by4 Apr 10, 2007 (5:50 pm)
I have a 1997 GMC 4x4 Ext Cab p/u with a 4.3L. At speeds above 50mph I hear what sounds to me like something binding then releasing and then there is a clucking noise. I checked and everthing seems tight under the frontend. I also have put it in 4HI and 4LO thinking that maybe the 4 wheel drive didn't completely disengage. Any suggestions on what to check next?

Replying to: 97gmc4by4 (Apr 10, 2007 5:50 pm) There used to be a service bulletin regarding a clunk in the transfer case that said to flush the transfer case, but a new bulletin has been released to update it.   File In Section: 04 - Driveline Axle Bulletin No.: 99-04-21-004A Date: September, 2001 This bulletin is being issued to advise dealerships to no longer flush and replace the transfer case fluid when a customer comments about a "bump" feeling when the vehicle accelerates from a stop. When Corporate Bulletin Number 99-04-21-004 was issued, a new transfer case fluid had just been developed to correct this condition. Currently, a nickel-plated slip yoke is being developed that will correct this condition. A new bulletin will be issued as soon as parts are available.   I would start by replacing the transfer case fluid and checking to see if the transfer case chain is stretched. The new yoke for the driveline doesn't seem to be available yet, so I would remove the driveline and get some lube for the slip yoke from your GM dealer and lube it real good and re-install it. The clunk may be from the slip yoke hanging up on the splines.
#54 of 172 2004 GMC Sierra chirping noise by mundyje Jun 04, 2007 (7:32 pm)
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.

Replying to: mundyje (Jun 04, 2007 7:32 pm) When was the last time that the truck was greased? Replies to this message: mundyje (Jun 05, 2007 7:14 am) davethecarnut (Jun 06, 2007 9:59 pm)

Replying to: obyone (Jun 04, 2007 10:09 pm) 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. Replies to this message: 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.
