0.0625''? that seems like a mile. how did they check it? did it have ton of weight on it? I'd expect .015'' as normal.

It's in my first post...

My shaking issue has been fixed so I will tell you what fixed mine and I would almost guarantee this will fix them all. I was building up my 6l80 with some performance parts and sent my shaft out to

Well my symptoms where just that.... a SHAKE! It would shake between 50-60 the whole cab would shake. It felt like King Kong was trying to shake me out of the truck. I could even feel it in the steeri

You could check it yourself with it still in the truck. Just put a dial gauge on a good sturdy mount or base with the back wheels raised and watch the dial indicator as the driveshaft is rotated by ha

Well I hope it works out as you said it did for you. You should send the bill to your dealership to handle this. Lol

I thought of doing that, but I'm just glad the saga is over.

Years ago I had vibration in my 1995 Nissan pickup that felt just like tires badly out of balance. It turns out that the driveshaft center support bearing rubber bushing got torn and the driveshaft was free to vibrate. I found the problem myself just by inspecting the driveshaft and being able to physically move it up and down about 1/2 inch. $ 110 later for a new bearing assembly and some work, I fixed the problem. So yes, vibrating driveshaft can produce symptoms very similar to badly balanced wheels.

I work in a machine shop. What is the tolerance for runout, or how close did the shop get yours?

They shoot for .005 and less and mine was .0627 from factory. Glen also said AAM uses cheap tubing made in mexico on their driveshafts compared to Wansley Machine made in the U.S. tubing which is nice looking and very very straight to begin with and easier to hit the lower runout numbers.

I wonder if your driveshaft was also balanced wrong (or not balanced at all).

07Softail,

 

Do you mind sharing who and where in Mississippi fixed your drive shaft. I need to pay them a visit.

 

Thank you in advance.

I know this is a long shot but does anybody know a competent shop in the Tampa Bay area? I need to look into this.

Damn man... how many times do I have to say it was NOT OUT OF BALANCE....They trued it first and checked balance and it was fine. No other weight was added and I looked to see when i picked it up.

Before you had it trued, did you ever put your truck in neutral while it was shaking/vibrating?

Mine has the shake, and it still shakes while in neutral. The driveshaft is still spinning.

Good to know. Mine still shakes if I throw it in neutral going down the highway too. I was curious because my previous truck, a 2000 Silverado z71 with a dented up driveshaft & worn out u-joints, would stop shaking if I put it in neutral while driving. Whenever I get some time off, I'm going to drop my driveshaft off at a specialist

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
