I was afraid to get new tires because it could have made the vibrations I had a lot worse. Luckily it cured them instead, finally. But after FINALLY having no vibrations, I was afraid to do ANYTHING that might bring them back, such as rotating the tires. But it had to be done so I did it. Thankfully no problems.

one2doo I told the guys at the Hunter booth SEMA to train the dealerships about the smart balance. My dealership was afraid to rotate my tires when I had a oil change. Goof balls I did it myself and no vibration. Amazing

Keith67 Mine was the stock tires. Totally stock truck with 12,000 miles. Finally got new tires (Cooper ST MAXX 270/75R18) and had them installed and balanced at my local Discount Tire using their Hunter Road Force Elite balancer. I told them about the vibration and asked them to turn off the "smart weight" setting. Amazingly after the install I have ZERO vibrations at any speed. Truck is perfectly smooth at all speeds. What a relief.

Congratulations on finally getting the tires balanced correctly.

badunit Mine was the tires. Two different trucks (one gas, one diesel), three different sets of wheels (one 20", two 18"), four different sets of tires (two different brands, two sets of which were road force balanced) and I had vibrations the whole time, to varying degrees. Then the tires with the least vibrations finally wore out so I installed a new set of tires with road force balancing. I was worried it would get worse but it is now smooth as glass to at least 90 mph. Absolutely no vibrations. It is possible, of course, that one of the other sets of wheels was also part of the problem but the tires were definitely a problem.

Edit; forgot to add that I leveled it in the middle of all that, with no change in vibration. Only after changing the tires did it quit.

Ya, I guess I didn't word my question well...what I meant was, what does it mean that they weren't "calibrated" correctly? Spring rate not appropriate for the weight of the truck I assume?
Just curious because I've never heard of this issue before... and wondering how common this is?

kingdaddy In my view this ubiquitous problem (though root cause varies from truck to truck) has to do with a uber stiff-robust frame that can develop a sympathetic resonance from a variety of any one of other causes, such as tires, wheels, springs, torque converter, driveshaft, etc..In my case the DRW rear leafs were improperly calibrated (fixed out of pocket via a leaf spring re-arching) - the passenger seat back vibrated about like an out of balance wash machine. Quite naturally the factory (via Chrysler Care call center) unilaterally disavowed the FACT that a ‘vibration defect’ may exist...Buyer beware...


What exactly was wrong with your leaf springs? And how did that contribute to vibrations? Not doubting, just curious...

I've thought this as well ever since owning a new body style '99 GMC Sierra. My favourite riding trucks are probably half ton GMs from '88 to '98.

My truck suffers from some vibration and so I thought I might find the answer here. Of course I started with a basic rotation and rebalance (by "rotation" I mean a side to side swap on front and also did the duals on the rear.

On my truck, the vibration is at around 65- 75 but varies in intensity seemingly at random! Sometimes it is negligible, other times fairly annoying...although never truly severe in magnitude.

I'm going to get a GOOD road force rebalance done and have them check every parameter possible to either find the problem at this level, or at least eliminate the tires and wheels from the equation.

In my limited reading of the posts on this thread, it seems quite obvious that there is NOT one source or cause of the vibration and so consequently there is no single solution either. Makes it a bit more challenging for any single owner to find the answer for their own unique circumstance!

I know... some have adamantly stated that it IS NOT the tires and/or wheels. Yet, others found that either proper rotation and balancing (key word: "proper") solved the problem. I've seen gear swaps, spring re-arching, torque converters, etc. etc. also listed as solutions as well.

I love the truck for the most part. I could live with the vibration (although I don't like it of course) but I'm gonna start with the most obvious, simple solutions first in my trouble shooting endeavor and take it from there. Probably be doing a tire upgrade soon too, so I will see if that helps apart from balancing etc.

I haven't noticed a specific model correlation thus far...i.e. DRW vs. SRW, MegaCab vs. Crewcab, long bed vs. short bed., transmission type, model year, 4 vs. 2 wheel drive etc.

I will post my progress, and encourage others to continue to do the same...maybe with less personal attacks and unnecessary "stirring of the pot"?
FWIW, my vibration WAS a result of my wheels. I switched them up to a nice/more reputable brand wheel and it 100% solved my problem, thankfully!

There's a post or two buried in there with a rear end off the ground and in drive. You can see the wheel/rotor/caliper wobbling. Add that to your list to check.
