| I recently bought an 08 GMC Sierra. I have noticed that it has a vibration and roaring noise coming from the rear of the vehicle when I put it into gear before moving and also when I am accelerating or decelerating at varying speeds. I have read several other posts regarding similar issues, but am unsure as to what to try to explain to the dealer's repair shop when I take it in for this problem. Could someone please give me some real insight into this problem? | |

I seem to have a shimmy/vibration when reaching 50miles per hour. Just had the u-joint at the driveshaft replaced. Any suggestions on what this might be? Thanks in advance. |

When you accelerate or decelerate and the truck reaches about 1300-1500 RPM the rear end makes a grinding/vibrating sound (low pitched). It also seems to make when driving steady speeds on the highway. I took the truck in to the dealer's shop and they told me that it was the heat shield on the muffler. The fix was to install a strap over the heat shield to hold it down. They installed it. I drove out of the parking lot with the truck making the same noise, maybe even worse than before. I called them back to let them know that it was doing the same thing. The reply....just bring it in again. I am getting pretty tired of this on a $20,000 truck. Has anyone else had this type of problem? |

A while back I posted that I was getting a squealing/chirping noise on my '02 1500 4x4. I figured it was the brake pad squealer as I just bought the truck in December. Took all the wheels off today finally, and all the pads are worn evenly and still have about 3/8" left. So the pads aren't worn down. The chirping is speed dependent and never turns into a continous squeal up to about 45 mph, which is where I can't hear it anymore. If I'm going 25-30mph and it's chirping, if I put on the brakes lightly it seems to go away (although it's replaced by brake squeal). I tried shooting brake cleaner on all the pads/rotors today and this made no difference but to quiet the brake squeal down some. My Dad rodei n the back and hung over the rear wheels and said it sounded the same from both sides. The front wheels seemed tight, there was a little play in the rear wheels, but you had to really hoss on the wheel to feel it. Any suggestions onwhere to look next?

I have a 2000 GMC Sierra Z71, Ext cab, 4wd, 5.3, 174k with front end vibration from 45-65 mph. It feels like a broken belt in the tire. Tires have been rotated to all 4 corners with no change. There is some side to side play in the left front but none up and down. The lower ball joint has a little movement as well. The right side is tight, no problems. Could it be a wheel bearing? Any thoughts are greatly appreciated.
