i like to know can you adjust the height on Tein while the shocks/strut is in the vehicle?

i try to lower it but that huge arm is in the way

do you use both wrench or single wrench will do the job?

 

You have to use both wrenches. The below assumes you have Tein Basics or SS.

Most will tell you to put one wrench on each collar and push them in either direction. That sucked for me. I found it far more effective to put a wrench on either collar and PULL them in opposite directions. You can generate far more force, usually, by pulling. Once you break apart the two collars, you use one wrench to lower the lower collar to the desired height. You can then likely hand-spin the upper collar (which the spring sits on) down to touch the lower collar. Then, get your wrenches back out, and lock them together by spinning them towards each other. Make sure you get them good and tight but don't go nuts.

 

It sounds easy to lower it. but im not sure how tight should you pull the collar to lock safely.
is it the same process for highering the car?

 

those are really good instructions. i wish i saw those the first time I tried adjusting mine last yr. I didn't really figure it out myself until a few months ago.

to raise the car, you loosen the car with the above method, and then you just use the wrench and adjust the collar the oppositte way. you then move the locking collar up to the other collar and "push" on them at the same time a few times.

you might have to clean the threads out with a vaccum brush or some brush. i had sand and dirt on mine and it was nearly impossible to spin the collars with the wrenches.

 

i thought lower the setting is suppose to make the collar go up
i need to clarify this before i start. it sound like PITA
