Vibrations over 70 MPH

bss · 11-06-2011, 07:36 AM

I have a 2011 Danali HD 2500 with 18000 miles. When I bought my truck in January I had a vibration over 73 MPH. Not sure where it's coming from. I thought it was the shaft out of balance or wheel out of balance. The dealer told me this is normal but Im beginning to believe otherwise. It is perfect from 0-70. Anyone else having this problem?

I've had my truck up to 95 and never any type of vibration, its a 2008. That was before and after all I've done to it.

That's what I thought. He told me that all HD2500 had this problem. This vibration gets bad. Very annoying. Anyone else, or is it just me.

Fill out your Sig so we know exactly what's on the truck, and does the vibration go away, did you buy the truck new or used, has it been there since day one

did they say anything about "frame beaming"

Sounds like a bad tire or out of balance tire, have them all balance checked and rotate positions. My 3500 is smooth but don't usually go over 70 mph,speed limits are lower here due to the sharp corners(and lots of them)here.

Ive had the same problem and am now at 5000 miles and its super aggrivating on a long trip. It could just be an out of balance tire idk I havent taken it back. Those guys pissed me off right from the get go. There was an earlier thread having to do with a wheel problem as well. Might want to search for it.

I bought the truck new. It has had vibrations from the day I drove it off the lot. I'll drop it at the dealer since its under warranty. Rebalance then rotate and Ill go from there. Speed limit is 70 mph in Tennessee... I drive 80 miles a day at 75 mph so you can imagine how annoying this is.

Yeah man. I may take mine in this week to. It needs it. Let me know if that corrects it.

By the way guys, these trucks are notorious for having the back wheels "hop" at freeway speeds. If you find a rough highway you can sometimes watch the tailgate bounce because there isn't enough weight in the back. Not saying this is your problem but I threw a couple hundred pounds of sand in the bed and my problem fixed itself...
