Is it your axle or you bed? A lot of people on here complain about misaligned beds.

Really........only 3/4" on a mass produced truck?

 

Forget how it looks, what is important is geometry. It's not the distance from fender to tire it is same measurement from the edge of the leaf spring or the shackle to each wheel hub that determines if the rear axle is centralized. And then the wheels on the rear axle must be aligned with the wheels on the front axle otherwise the vehicle will "crab" down the road.

 

Quick and dirty test is to drive straight ahead on a wet surface and observe the tracks left by the vehicle - they must be one tire wide, i.e. the rears exactly overlap the fronts. If wider the axles are not aligned, vehicle is crabbing and front and/or rear axle adjustment and front wheel alignment is required. If axles are aligned but it still "looks" off, you don't shift the axle, you shift the bed and split the difference 3/8" so it "looks" better and live with it......really 3/4" on a Chevy????

First things first: you need to use the same lug on the tire to get your measurements. Can’t measure on one that runs out the whole width of the tire against one that doesn’t. They need to be the same.

 

2nd: looks like it might be off by half an inch.

 

I don’t know why people look at these things. I haven’t looked at the bed or my rear axle because I don’t want to know if it’s off

The only proper way to measure this will be with the wheel off and using a level against the face of the axle shaft.  Or have the alignment checked as something could show up in the thrust angle measurements. 

 

Your tires are creating too much variance here.  Is the truck driving funny or anything?  I guess I'm not sure what the worry is.

I’m measuring of the frame not driving bad at all but that’s why I’m asking if this is same on other trucks don’t need tire wear or other problems down the road

You are clearly measuring it differently. There are two different lugs on the tire tread. They are staggered. You are measuring one in and one out...your not measuring the same outside lug. But as other have explained, you need to measure the axle not tires. I dont think you have any issue. An alignment shop will tell you immediately.

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      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.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
