Nbs Highway Vibration

[Dontech]

I have a vibration between 60-70. I feel it in the wheel. I have replaced the tires, no better. I have had two Road force balances done and they come up good. The truck has been at the dealer ship for two days and they have no idea what is causing this problem. They have checked the drive shaft, wheel bearings, and are now going to try a vibration monitor on the stearing wheel. Has anyone else had this problem and had it fixed? Does anyone else have Vib's in their new trucks?

 

Any help would be great, the service manager seems open for any ideas. They are going to try to compare my truck to a truck on the lot today with the vibration monitor.

 

Thanks,

I feel my vib a little all the time but when I reach 60-70 it levels off and does not get any worst even if I go faster. Did your truck act that way?

i haven't felt any kind of vibe while driving mine sorry.

Vibration is one of the most annoying issues and difficult to solve at times. What replacement tires did they put on the truck? Same as original? You mentioned they did road force balancing - I assume on something like Hunter 9000 model balancer or equivalent? Did the new tire pass the road force test with a good margin? What were the force variations in pounds. typically, up to 20 lbs is considered acceptable for a passenger car tire. I have seen tires with as low as 2lbs.

 

Michelin LTX M/S has very low road force variations. That would be the best tire to try.

 

Other things that can cause vibration are unbalanced brake rotors and drums. Do you see a metal weight welded to the outside of drum on each rear wheel? Rotors are typically balanced when made by machining out some metal, usually on the inside in the ribber center near top.

 

Driveshafts can certainly cause vibration. have they taken out the driveshaft and checked it for balance? there are special machines that balance driveshafts. Also, the driveshaft could be bent, which could also cause vibration. Your truck probably does not have a center driveshaft support bearing, but a torn rubber bushing in the support bearing mount could cause unpleasant vibration - just like wheels out of balance. I had this happen on a compact Nissan pickup.

 

Also, have them check all suspension components meticulously - ball joints, tie rods, and anti sway bar bushings. Make sure everything is tight and no parts are missing. Sometimes even a damaged shock absorber can cause wheel hop and vibration )not likely in this case, but I have seen it happen).

 

Good luck solving this issue. I know it is frustrating. I have been there myself with some vehicles I had. fortunately, no issue like that with my '06 truck.

I had BF Goodrich AT/ko's installed which I know is not the smoothest tire but I had the exact same vibs even after they were installed, and the RDForce was about 10 psi on them both times. They told me they checked the drive shaft articulation (spelling ?). It fell with in spec. I know that they had the back of the truck up off the ground and running the tires because they threw the ABS code. I did ask about the brakes. The drums and rotors, I told them that they squeel, but from what I have been reading here it is common. But I will ask them again to check them out. Thanks for you help, I wish I had all the tools to do the work myself but I don't. This is very frustrating.

I was told that I have a bad torque converter. They are ordering me one to install. 19000 mi

I have the same problem..and they are too replacing my TQ converter today

I have been doing some research and this may be a common problem.

 

Can you let me know how it works for you.

No problems with my 2008 yet, but I have less than 2000 miles.

Hello, I own a 2007 Silverado Crewcab 4x4 1500. I am currently experiencing vibration from 35-70 mph. It's been to the dealer 3 times for the problem. They've balanced the tires and turn the rotors three times. They claim the vibration is the result of the Active Fuel Management, but the vibration is present regardless of which mode the truck is in. The truck has 5100 miles on it.

 

I got the truck back today and the vibration is still there. The dealer has pretty much washed their hands of the problem by referring me to the TSB regarding the vibration. TSB #06-06-05-001A-(3/20/2007)

 

Does this sound like what you all are experiencing? I'll be watching this topic to see if the torque converter is the fix. I'll mention it to my service manager the next time I speak with him.

 

Happy Holidays.

Now it is torque converters dying out?? C'mon...what's next with the NBS trucks???

 

Another poster, a few weeks ago, made a comment actually wondering how long the torque converters would last, considering the active fuel management system is locking and unlocking the converter constantly...

 

Seems they won't last long. Another weak link NBS topic, like oil leaks, etc...

It's funny you say that because i swear at times i have the same "rumble strip" feeling that has plagued the new tundra. And that has been sourced back to the TC.

[Dontech]

Can anyone explain how a TQ converter locks, and how the trans shifts into another gear. I understand some of the theory as far as the fluid circulation that I have seen in some sites that I have been looking at.

 

Are these common fail points? Are chevy's prone to this type of problem?
