#1012 of 1492 Re: 2004 Sierra Z71 clunking noise from rear [gmcbob] by joejo May 06, 2005 (3:45 pm)
Replying to: gmcbob (Jun 20, 2004 10:26 pm) i"m having the same problem but getting worst. it sometimes bang into gears in stop and go traffic. i hear the rear diff bang like thirs to much play in it. the trans seams to also slip a little. the dealer trys telling me thats normal. Ya O.K not  for a 35K truck. i only have 5k miles on it and they told me i would have to live with it until it brakes down so they find the problem.

Replying to: dantana (May 06, 2005 4:56 am) Just read your email about the vibration in the drivetrain. This 97 GMC has the same thing only when I let off on the gas between 52-68 MPH the whole truck vibrates...when I am pulling a load or going up hill it is much worse.   Tranny is three days old and did not cure anything. All differentials have been gone through...engine throws no codes.   Can't drive it comfortably and can't sell or trade it the way it is.   Norm Replies to this message: mekchalngd (May 10, 2005 8:40 am) dano7 (May 23, 2005 2:26 pm) mekchalngd (May 26, 2005 6:02 am)
#1015 of 1492 Re: Sheel Metal Noise... ROOF? [fishersc] by weels May 09, 2005 (6:19 pm)
Replying to: fishersc (Dec 17, 2004 12:25 pm) My truck does this when I go through the new brushless car washes. The only idea I can think up is to take the headliner out, and see if there is any access to the area between the panels (at least part of the roof is double) and squirt some builders foam (like Great Stuff) into the void to try to stiffen it up. If you have clearance lights you could pop them off and get to it there. I'm going to try it this summer. -Tim Replies to this message: baredogg (May 10, 2005 5:38 am) weels (May 10, 2005 6:40 pm)

Replying to: weels (May 09, 2005 6:19 pm) builders foam will hold moisture ie. condisation and will cause rust thru a better choice would be a flexable sealer (non alkaline) to somewhat attach and isolate the panels there should be a factory applied heat reactive sealer there now but it could be a missed robot path aplication. Hope this helps Replies to this message: weels (May 10, 2005 6:40 pm)

Replying to: nspidell (May 08, 2005 8:59 am) Have you checked the U-Joints? Apparently what you are experiencing may be caused by slack in the U-Joints, and the vibration gets worse while under a load. The factory installed joints are sealed and cannot be lubricated, the aftermarket ones can. Replacing these may rectify the problem for you.

Replying to: baredogg (May 10, 2005 5:38 am) Good point about the moisture. Thanks - Tim

#1021 of 1492 Front end popping by claw May 12, 2005 (6:41 pm)
I just purchased a 1998 GMC 2500 3/4 T Serria.73,000miles. It hasnt been maintained too well, but over all a good buy and pretty good shape. I had to replace the water pump, tires, brakes. What is driving me crazy is the popping in the front end as I turn. Nothing on inspection showed wear and needing to be replaced. A front end man told me there was aa recall on this front end. he claims that the way the dealer fixed the popping was by placing a certian kind of grease in the joints. I cant believe this, but it does not pop as bad after you grease the front end. After one week of driving the popping returns gradually and prossiveily louder......Comments welcome.
