First off, turn off the all caps. Hard to read and I don't like being yelled at this early in the morning.
 
Secondly, does the sound change with increase or decrease with speed or is that clicking constant, regardless of speed? I'd check to see if you have anything wrapped around the driveshaft. Can you tell if it is coming from the front or back? Have you looked in the engine compartment to make sure the fan is all intact?

#25 of 28 Front Right Suspension Clanking Noise by 1233fire

2003 Z71 with 111,000 miles. While driving at 45 mph under slight acceleration on straight stretch of road, all of a sudden I hear an erratic clanking noise like a brake shoe came loose or a steering knuckle is separating (from my old jeep days). The clanking noise changed with the speed of the wheel as I applied the brake. There was no squealing or rubbing sound. Under the truck there was nothing showing abnormal. I was able to return home 2 miles under slow speed with occasional recurrence of the noise. It was significantly noisy like what you would expect if you had a pretty large piece of rubber hitting the body or undercarriage as the wheel turned. It was not constant as you would have with a separating tread. It really sounded like a large metal object. Any suggestions on what might be the problem? Thank you

Have a 2005 Chev Avalanche 350 V-8 with 95,000 miles.
 
Have slight vibration at idle and when reached 40 mph.
 
Had Tranny and Torque converter checked. They are fine.
 
Engine and transmission mounts were replaced.
 
Universal and CV joints replaced a while ago.
 
The mechanic is now saying that vibration could be internal to the engine.
 
Any suggestions.

I see that you’re already working with your mechanic to diagnose the vibration concern you described. If Customer Assistance can help you work with your dealer towards resolving this, please email Christina with your name, contact information, VIN, and dealer name.

hey everybody. I have a 02 avalanche with 146,000 miles on her. bought it back in July of 2011. All stock besides tail lights, strobes and dash lightbars. only put just under 3000 miles on it now since then. i noticed when going after being stopped at a light and then go at a normal slower speed instead of hammering it down that when it shifts i hear a noise. but if i give it a lil more gas after stopped it doesnt seem to do it. idk the owner before me has all records of everything done and i keep it well maintained to checking all fluids every week to even cleaning her 2+ times a week. but today was the most i noticed by far when i drove for about a hour. A few side streets and about 20-25 mins freeway But i only noticed it def. when it shifts from 1 to 2. My brother a mecanic so im going have him check it, but wanted to see if there was any other Av owners who had similar problems?
 
Thanks,
Glenn
