08' Crew Vibration

[1fastchevy]

1500

Anything over 100 Im getting a horrible vibration from the driveshaft.

anyone else ?

Common problem ?

Should I just try and have it rebalanced?

That's one reason why GM has a 99 or 101mph limiter on the trucks.
It's probably the driveshaft, since the truck is so new, unless you've modified the suspension.

I've felt this on a few trucks I've tuned.

danger bro,ide stay away from that till u get a built one,the denali is still untuned as of now so im not sure if it will vibrate.
is your lowered?

Is your's 4wd? mine did it at around 110 or so but smoothed out completely from 115-125 just a slight vibration buzz then went away.

its a 1peice aluminum one correct? its gonna do that bc its not high speed balanced. keep it up an you could cause it to break an destroy a lot of crap. i have an 08 CC an im swapping in a custom 2 peice driveshaft an have the u joints swapped to a 1350 an high speed balanced for 200mph

Thanks guys,

Works owning me right now.

Its one piece aluminum and I really dont hit those speeds much in this truck its no racetruck by any means, slowest truck I've ever owned by far.

Ill try and have it balanced and if that doesnt help I'll check into a 2 piece, I really want to keep this truck for a long time and I dont want the vibration moving into the tranny or tearing up the rearend.


Sorry, not 4x4 and its lowered 2 " but the angles are great its just the speed that its turning at 110 and up is to much with stock balancing, it is a big mofo driveshaft and long.
