Re: DIY homemade air suspension links. Install with pics!

Thanks for sharing your alignment results. That's what I was worried about. I assume that the alignment was done at normal ride height.

That's quite a bit of negative camber. A normal passenger car/suv should be in the -0.5degree area. Performance cars (daily drivers not track cars) should be in the -1.0 to -1.5 degree area.

Being at -2.5 will lead to a lot of inside tire wear. Tires for these trucks are expensive...and you would certainly see bad inner tire wear on the fronts. Less so on the rears, but it will happen back there too.

I'm not too concerned about the caster. The toe should be easily adjusted back into the green zone.

So where did you end up after the alignment?!

Re: DIY homemade air suspension links. Install with pics!

I told the write up guy - went to my local Goodyear dealer - that the vehicle has an alignment mode and that I had installed lowering links. He knew about the alignment mode but what if the actual person doing the alignment didn't know? Or does their system give them step by step procedures? They did not supply the 'after' results. Might take it back later today and just double check. As far as tire wear, I did not notice any and I would think that with that much -camber and -toe that I would see some.

Re: DIY homemade air suspension links. Install with pics!

That's strange that they didn't supply after results. Usually you get two printouts with the before and afters.

Otherwise how do you know they did anything?!

Please report back what you find!

Re: DIY homemade air suspension links. Install with pics!

Well took it back in this morning and I just gotta say WOW!!!! Nobody at this tire shop knew about the 'alignment mode' on these vehicles. How long has the Quadralift been around 4-5 years? I am sure they have had Summits or Overlands in their shop for alignments. Not to mention all the other vehicles out there with air suspension. Are all those vehicles driving around with incorrect settings? Wouldn't you think that with todays technology that the alignment guy would scan the VIN of the vehicle and the alignment machine would give him step by step procedures for that vehicle on how to do the alignment. And I don't know how much truth is in this statement from the alignment guy 'it doesn't matter what the camber and caster readings are as long as they are almost the same left to right'. I guess when they initially put the vehicle on the rack Saturday those readings were at exit/entry height which is why they were so far off.

So I waited almost 45 minutes for them to realign it and here are the readings now. Much more green.

Is this new alignment post your old alignment settings? Meaning when you took it in for alignment and the report read all red, they performed your first alignment. Now this second alignment is to fix the first alignment? If this is true then you wouldn't know how bad your initial (with recent links install) alignment was....

Re: DIY homemade air suspension links. Install with pics!

Alignment shop techs are idiots. They never get training on new vehicles so they just keep doing "what they were taught traditionally." Brought my old 2015 Sierra in to Firestone and they had no idea what a steering center recalibration procedure was for the electric power steering.

Literally all they have to do is go in settings on the touch screen and set it to alignment mode which puts it in sport mode height. Guarantee it was either in normal driving or park mode the first time, which is why you had all the red. I'm not even worried about alignment after lowering it because it sits about what sport mode was with it in normal driving mode.. and I don't have the erratic sport shift pattern. Win win.

Correct. I have no idea what my before settings were and really can't do anything about it.

Re: DIY homemade air suspension links. Install with pics!

Thanks for sharing your results. I also hate alignment techs...they do the bare minimum to adjust the car until it's just barely in spec and that's it!

They don't care if one rear tire has negative toe angle and the other is positive. They don't care if they are just inside the spec tolerance or dead on the nominal spec. Sometimes they just wiggle or reposition the sensors on the wheels until it passes. What a joke!

Anyways...it looks like you are just about at -1.5 camber all the way around. What we don't know is how alignment mode is different from normal ride height or aero mode.

I'm guessing you are running a little more negative camber than you would be at stock ride height. You may still see some increased inside tire wear. But that's the price we pay for a proper ride height!

Thanks for sharing. I'm still going to build some lowering links...parts are on their way.

I think when the vehicle is in alignment mode it is in aero - at least that is what the display reads. I think it is that way because most driving - at least for me - is highway.

Re: DIY homemade air suspension links. Install with pics!

Thanks for trying anyway blk14altitude! leave it to some shop to do things wrong. Not surprised really. If they checked the alignment in entry-exit height then yeah all the readings will be messed up just as they were. Glad to see it looks like they figured things out...atleast I hope they did. Its reasons like this that I am always hesitant on letting someone else touch my vehicle. People literally have no clue, nor do they really care if something is done right.

Re: DIY homemade air suspension links. Install with pics!

Well, I received my link ends and threaded rod today. Tomorrow, after work, I'm going to build the links according to the dimensions that JTS provided. I'm really looking for a 1" drop front and rear.

JTS - i have a question about the dimensions you provided for the rod itself. If the rear rod length is 1.75"...does that make the rod bottom out inside the end sockets to achieve the overall center to center length of 3.25?

I know I can always trim more off the threaded rod for the rears (to lower further)...so I guess it's not really a big deal.

With the fronts...I will be able to thread the end sockets out to lower the car and further...so the fronts wont be an issue.

Did you use any thread locker on the jam nuts? I know there's not a lot of stress/force on these links...but they will see a lot of vibration!?

Thanks again for all the help!

Re: DIY homemade air suspension links. Install with pics!

nPickel12, I suggest caution about the idea of lowering further than the approximately 1" that JTS's dimensions provide. You could start to impact both ride comfort as well as other factors. We've talked a little about that further back in the thread.
