Popping noise on my 04 GMC Yukon after turning it off. Seems to be coming from under, near the rear wheels.
loud rattle noise from under the center of the car. when in drive. Seems to lessen when in park. Sounds like hell. Mine became loose from a weld - re-welded and good to go. LOVE MY TAHOE!
Intermittent rattling of the muffler. Took it to a service location numerous times only to have the noise disappear when they tried it. Finally, an adept technician warmed the vehicle and drove it around the block a few times and heard it. Seems that temperature and speed were a factor. They welded it once for me, but it didn't hold for long. Ended up replacing with a magna flow muffler system.
I My 2005 Tahoe's also rattles as I accelerate.I notice that while under the vehicle, the shield is very flimsy(prone to vibration right where the exhaust sensor is.I have thought about wedging some exhaust wrap between the body and shield.
