Hey guys, got an issue trying to rewrite the ride height on my truck. What I’m trying to do is level it from front to back so I don’t have to keep using my aftermarket front adjustable leaving links.
It’s a 2018 Limited 4x4 and before it started anything, my factory values with the stock links put back on were as follows:
The inch measurements is from the ground to the bottom of the upper wheel arcs with the wheel hub in the center.
FL Cal Height: 70 mm - 36
FR Cal Height: 75 mm - 37-3/8
RL Cal Height: 79 mm - 38
RR Cal Height: 77 mm - 39-1/8
My first attempt being that as you can see, it’s around two inches taller in the rear and from left to right, it’s pretty much a tad over an inch higher on the right.
I went in, made sure there were no codes stored in the ASCM and then went to the part where you re-write the values. I figured I’d start off by raising the whole left side so I went from 70mm to 73mm on the front-left and from 79mm to 82mm on the rear-left. I left the right alone. I followed the instructions and cleared the two codes like it instructed you to do so after recalibrating, I disconnected from the ASCM, shut the truck off, locked it and waited a few minutes before I turned the truck back on, used the buttons on the dash to raise the truck to OF2 mode and then brought ir back down to NRH. I took my measurements from the ground to the tops of the wheel arcs and my FL didn’t change as it’s still at 36 inches. My rear left however, went down from 38 inches to 37&3/8 inches even though I gave the command to go up to 82mm from 79mm.
I guess I could understand the left-front not going up if I just need to go up further in the MM number but I don’t get why the LR went down instead of up.
Also, does it mess the calibration up when after you leave the vehicle for a while, the pump will just kick on at random and re-level the truck. Is that messing me up too? Also, my drive way is level but it has a little downward slope from the house to the street. Is that messing with me too?
Please help.
