I hooked my 2002 LX470 with 80K miles up to techstream yesterday to see what my neutral pressure readings were after replacing my globes. I was only getting like 6 graduations from the old globes and my front suspension felt like it was stuck in sport mode. After replacing the globes I have 14 plus graduations but the truck still feels like its in sport mode.
I hooked up the techstream , lowered the truck to L then back to N and checked my pressures. This is were it gets WEIRD. These were my pressure values.
Front 3.2
Rear 6.7
Accumulator 10.4
It seems like suspension is just using the torsion bars to hold the weight of the truck. I then make sure the truck is on level ground and then I proceed to get the front driver side and passenger side level. After getting the front level 19.75 hub to fender I crank counter clockwise 7 full turns then recheck my numbers. The front pressure jumps to 10.2....what???? So I go back clockwise 2 turns at a time until I got to about 8.3. If I turn each side a 1/4 of turn it will drop back to 3.2. I don't get it...… While the truck is going from L to N it will show Front 6.7 Rear 6.7 and it will stay that way for a few seconds then when the pump stops running the rear will stay but the front drops to 3.2.
If I leave the front at say 8.5 and drive the truck it rides pretty decent but once I try to get it in spec like anything below 8.0 it just drops to 3.2 and rides like crap again.
Does anyone have any ideas? These are the things I've done
Flushed a year ago and again when I installed the new Toyota globes.
Bled the system really good twice.
