Default Different air bag pressure?

Why is it that one air bag needs 131 psi (left front)....and the other only needs 105 psi (right front) to get to the same height?

Does it mean my left front air bag is stretched and needs replacement soon?

Or is it my pressure sensors needing replacement?

also dont forget the driver side is usually heavier due to you sitting on there, steering column n what not..

are the air lines the same length? Could also be the air sensor or gauge not being as accurate.

It's is most likely weight load no car is evenly balanced on all four wheels, this was my issue w/ lowering springs all the springs are the same but lowered my car to a different height all the way around I hated if even though the factory springs did the same thing. I just didn t notice until my fitment and wheel gap became tighter. That's why I went with coilovers you can fine tweak everything!

yup its from the weight of the car and you also being on the same side.

i highly doubt its the air lines. if the air lines are different lenghts that would not have anything to do with why 1 bag requires more air than the other. only thing 2 different length lines mean, is that one bag will fill up quicker because it has less line to travel through.

if you feel that the air sensors are throwing something off u can always swap them around to see if the readings are the same way.. this is prolly the easiest way/cheapest way to start the diagnosis.

That's the same way with me, but I'm sure it's because of a blown shock for me.

get the car corner balanced .
26 lbs is a huge difference , to the point that corner should be hopping all over the place going over bumps .
Also get a quick calibration by airing up all 4 corners to max height equally . Then read if all 4 corners are the same as some sensors might have dirt on them and be blocking the correct readings.
