NOISY VIBRATION

[am70043]

I've read most of the post on vibration noise and been to the dealer hearing the same old story (normal). On my 02 ECSB 2WD two piece driveshaft Silverado, I have a very audible vibration noise between 800 & 900 rpm's at start up. The vibration feel and noise is much louder when the weather is colder outside, so it has to be temparture related. On a hot summer day you can barely hear or feel it. Any info would help, thanks.

I have the "upgraded" 2 piece drive shaft in my truck. The problem I had was with a trailer on the truck the shaking and shudder was awful. I had to bring the truck and trailer to the dealer to get them to perform the TSB.

 

Prior to replacement of that drive shaft, I had what the 4 wheel drive guys would describe as a bad slip yoke, step on the gas, wait and then a slap and a bam, then you were moving.

 

You could have a bad u joint, or someting else, I have never had a vibration with out towing. However the replacement drive shift with the double carden u joint makes a "ringing" sound when the truck is cold, and it's cold outside (say below 30F) around 1000 rpms.

 

Check this site out, lots of 2 piece drive shaft info.

I vote for the u-joints.
