that flyer does not say "Toyota" recommends this. therefore,that...
we have all read horror stories of KDSS being bled by people who do not know better. A spacer sounds much cheaper and less detrimental than doing this to your ride...
i'm going to be doing both.. even when leveling by recalibrating the kdss it still may not sit level(by toyota standards), so the spacers will get it there i'm thinking

let us know how it goes. also do you know about some toyota documentation that supports this "recalibrate the system" flyer?

This is a follow-up in case anyone is curious. Mine had a good lean going towards the passenger side, I would say 3/4-1". I consider myself mechanically capable, so if you're not, I wouldn't do it just because of the risk involved. I followed the directions to a T. I didn't back the bolts out more than 3/8" since they said no more than 1/2". To my horror, it was almost level afterwards. Big drama. Anyway, glad I tried it, it looks a lot better now.

Yea I already bought the spacers to level it and I'm gonna do the recalibration. I just moved to NC and don't have my tools or a garage to do it anytime soon yet

For kicks I did this, its a 10min job. 4 bolts (2x 12mm for the KDSS "skid" and then 2 x 10mm for the bleed valves. It may have made a difference but it was small (1/16-1/8")......before and after measurements are not with me at the moment. If you have a lean I would say give this a try for the simple fact that its an easy thing to try

go for it. let us know how it goes. a positive KDSS calibration story would be a nice change from all the horror stories.

Can anyone provide more specific instructions for this procedure? With photos perhaps? Would appreciate it very much.

its pretty easy brudda...
-park at a flat parking spot
-take cover off kdss unit
-work equalizing bolts out by 5mm
-get in 4runner or climb on rock rail or driverside door... rock car back and forth
-get in passenger side... rock back and forth
-close equalizing bolts off
-put cover back on
-FINI !!!

After having done this procedure numerous times over the last year, my lean keeps coming back literally on the first test drive after. Also, you can just shake the car back and forth without pulling out the threads and it will have the same effect. :noidea:

Same thing here... I pretty much resigned to my faith on this one. I gave up because it comes back. Shoot it even I turn a right turn the lean shows up... make a left turn down the road. It goes away... There's no use
