Had all four tires balanced today by an actual tire shop this time. A little less vibration but still has the shake. The steering wheel vibration has decreased a bit too. Oh well. At least I had it done for free. Guy said the balance that the dealership had done was horrible.

Hey guys just a thought. Would it be possible to lift the truck up on a lift, all four wheels off the ground, bring the truck up to speed, get underneath the truck and try and see if anything sticks out as the source of vibration?

I will do that next. Thanks. If it was the axle flange, wouldn't I feel the shake all the time? Mine does it at 45mph exactly and between 72-85. Thanks

I had my driveshaft balanced by a professional shop and my truck still vibrates.

I did some heavy hauling/towing recently. My bed had at least 800 pounds in it, and I was hauling a trailer with cargo weighing around 5,000 pounds. My truck still shook. At certain speeds the center console shook like it always does. Many friends always told me that if I loaded the bed it would be fine. Nope. She was fully loaded and still shook.

How would I check that? My dad and I rotated both rear tires while on the truck and they were spinning true. We put a dial gauge on the edge of both tires and had zero readings on the gauge. They were spinning true. I would think if it was the axle flange then my tire wouldn't be spinning true and the dial indicator would show a reading.

I did exactly that. Driveshaft was slightly out of balance. They fixed it and still vibrates.

Pretty much. I'm giving up on this soon. Tired of worrying about it. Soon as I can I'll get a other truck and never look at a GM product again.

Fully loaded 6x12 trailer.

How do you remove the lower bumper?

The engineer was perplexed? I call BS. No way that after all these years they still don't know what's causing the problems.

Never said they did.

Yeah if I wasn't taking a gigantic hit, I'd buy a Tundra tomorrow.

It's cool. It'll be the last dime they'll ever take from me. Next truck will be a Toyota or Nissan.

Exactly. How is it that this started with the 2014s and the 2017s are also having the same vibration problems.
