How do you take the measure on the tires? from the bottom on the ground to the top?

 

The tire size doesn't matter either 22.5 r 24.5 ,,,Any VNL volvo 64T SEREIES air ride height should be measured from the bottom of the frame to the center of the axle where you can see welding joint and it should not be less or more then 8 inches.

 

Hello good people. I was reading the whole thread about this ride height. My Volvo vnl 670, 2011 its vibrating for some reason i checked everything from driveshaft, u joints, yokes. New front springs, 10 new tires drives kelly’s and steer yokohama. New fuel pump on it. There is nothing that i can notice is loose. Like some of you guys said i went today on the lot to measure it and rear airbags from the welding to bottom of the frame 8 3/4 almost 9 and front airbags from welding to bottom was 8 1/2. What do you guys think maybe my ride is too high and cause this vibration coming under my truck and noise. Its noticeble in 6th gear and up it freaks me out everytime. I feel something will break anytime. I will also send a pic to show if my measurment is right. Thank you any andwer or opinion is welcome. Have a blessed day.
