What are your experiences with the ACCUAIR system?

[Gladiator_Tyler]

Soo I finally got around to installing my AccuAir system. It was fairly straight forward for the most part. I spent more time running air lines and wiring for the ride height sensors. tried everything I could to make it look as factory as possible. The control arm and air spring stuff went fast. I was surprised to see that the lower control arms for the front were not adjustable. They definitely add castor. I have put close to 100 miles on. What i have noticed is even though I didn't change toe or camber, It now pulls to the right. How is changing only the castor now cause it to pull the the right?

All actual mechanical things being equal before and after the install, my guess would be unequal corner weights. The system has height sensors all 4 corners and maintains pressure to maintain a base height yes?

Dumb question, Does the rig pull right or is the steering off? If the steering is off it is a drag link adjustment. if it is indeed a pull then could be a number of things. I found with the kit they sent me the bushing material was too soft. Also the rig needs to be at ride height before torquing down the control arm bolts. The soft bushing material caused drivability issues with mine rig (axle steer).

Also of note. I could not get my system to sit level at ride height. The minor adjustment allowed by the programming did not allow me to level at ride height. I found my supplied sensors are not to be very high quality. If the rig is not level then you will have a pull to one side.

To get my system ( Now removed) to work better I replaced all 8 control arms and used adjustable forged track bars. Something to check, are the axles centered at ride height? if not This could also be a issue with tracking.

Another thought is did you rotate tires? I have had this happen to me a number of times.

I hope you find out what is causing the issue. I had too many with mine and ended up removing it. waste of $7500.

It actually pulls to the right. The steering wheel was off only a little bit after the first drive. Like it was sitting at 12:30 at best on the first drive. There is a gradual corner on a highway near me that I could let go of the steering wheel and it followed that curve perfectly. I did torque at ride height. I am at 100 Miles on it and will do the retorque. May loosen and retorque and check again in another 100 miles. It sits more level now than what it did before I put the lift on. I did measure all 4 corners before the lift. right rear was 1/4" lower than the left. Front was the same on both sides. Measured tire straightness compared to the steering wheel before the lift. Also used a plumb bob to mark center for the axle so I could get everything back to where I started at ride height. I haven't rotated the tires yet. They are brand new and wouldn't have thought that i would need to do this. It is my first set of Mickey Thompsons. I've always been a diehard Super Swamper fan. I've run Swampers or BFG on all of my vehicles for the last 35 years without a steering pulling issues. Currently have 3 vehicles on Swampers, 1 on BFG and now 1 on MT. A local friend of mine that is in cahoots with Mickey Thompson has suggested that I try Mickey Thompsons several times. If it turns out to be a tire, this will be my only set. I doubt these will outlast my SSR's either. I'm just part of a brand loyalty generation. I talked with Steve at Accuair and he is more than willing to help to resolve the issue along with a friends JT with no lift that pulls to the left after a couple tries on an alignment rack. I just have to get an alignment printout for him. I will do that after a tire rotation that he too suggested I try. He was a wealth of information for the questions I had. FYI, he also reads this thread.

Yes the system has a sensor at all 4 corners. It can read a little different at each corner but I did try to significantly load one side more than the other. Not one side full up and other full down, but a 10-15% difference. Didn't really make any drivability difference.

Thanks Tyler! We'll do our best to get your issues resolved and that alignment spec sheet will definitely give us some insight as to how to correct this.

Some thoughts.
1) get a tape measure out and measure bolt to bolt center on ten left and right control arms. If there is a delta of more than 1/16 the bushing deformed.
2) Loosen the control arm bolts and bounce the corners ( jump on the bumper) then re torque to spec. re measure
3) if you get an alignment do a 4 wheel alignment. This will check to see if the axles are tracking straight. Thrust angle ( rear) if it is off this will drive a pull condition.
4) look at the APP and see if you can track the suspension height on each corner on a straight flat road. if you see a delta or a change on any corner driving straight and flat at constant speed there is an issue in the suspension.
5) Not sure what kind of roads you are on but all roads have a crown to them. find a road you can safely straddle the center line and see if the rig tracks straight. This will compensate for the crown.
