I discovered the solution while researching noises on the Edmunds Fourm. A six-speed automatic and 6. The Sierra retains the previous model's selectable, full-time, four-wheel-drive system and a generous load capacity. I feel like I'm driving a new truck. I actually have to tell it its in Florida each time I use it. However on the front driver side when tuning or even going straight and hitting a bad bump i can hear a clunk or rattle.
Hey all, I have a 2004 gmc 2500. I was able to fix the rattle problem. Takes about 5 seconds to go into drive, although no slipping. Every year we have a few replaced. Acceleration is certainly acceptable with either the 4. Mine is completely rattle free, I love it. Highlights included updated styling, an improved interior with higher-quality materials and tighter build quality, a more rugged frame and redesigned steering and suspension components for better handling response and ride comfort.
Side curtain airbags and adjustable pedals are optional on most models. Dealer claimed he replaced the O2 sensor. Also the door locks can rattle at idle, easily fixable with some velcro behind the tabs. A stability control system with roll-mitigating technology is standard on crew cabs and optional on extended cabs. Original 4L60E tranny, never rebuilt. I tightened it all back down and no more rattles! I popped the bottom dash panel off and there was a screw in there that had come loose causing the rattle.
It has held its own, particularly inside. I use to have an 03 yukon and it had the same issue. Interior Design and Special Features Tight build quality, an attractive dash design and comfortable front seating combine with sound ergonomics to make the Sierra's interior enjoyable on long road trips. I have a 2005 Silverado and I have this rattle in the dash behind the steering wheel. I take it back tomorrow for the third try. Don't know, but it does, and it isn't just the repairs I did.
I had the exact same problem with my '08 Sierra. I went with the mechanic for a test drive and he heard the sound too. Topics in this area contain discussion of door panels and headliners or the dash and carpet, trim, and seats. I cant seem to figure out what it is without snatching my entire dash off. We were pulling a travel trailer on a camping trip.
Now the brake lines are rusted through and several other major parts, as well as the wheel supports. Wheel wells on the rear started to rust out after about 6 years, so I've replaced them. The sound is completely gone. Full synthetic oil changes every 3000-4000 miles, light hauling never beyond capacity, all maintenance kept up and serviced regularly never raced or beat on and I am the original owner. I discovered the solution while researching noises on the Edmunds Fourm. A good spot to look is on the rockers, inner rear fenders, underside of hood, front body framing under hood, and underside of the doors 4 of 4 people found this review helpful Amazing work truck with 4. It does go away but it keeps coming back after a few days.
Just bought brand new Michelin Ltx tires. My concern is if the passenger side airbag deploys, it could send fragments of plastic that is deteriorating flying through the air and strike anyone in the truck. I also found that the cover which mounts in the 2 rubber grommets on top of the engine was vibrating and rattling on a wire harness that was right beneath it. Pretty darn good for hard driving if you ask me. I'll definitely keep it in mind.
Here are some part numbers for you, if you can make it go away for a few days with what you have been using then paste should work for quite a while. Buyers have a choice of two-wheel drive, four-wheel drive or, in the case of the Denali, all-wheel drive. It is too expensive to ignore. I owe you a dancing girl. I just had the same problem your describing. Shocks, wheel bearings,etc have all been checked.
