i messed with my sensor height rods about 6 months ago and i'm sure they are not 100% even and correct. i would like to have the dealership put them back to factory spec so i called the dealership.

lex of annapolis told me to bring it in and let them look at it. the last time i did this i paid them like 180$ or $210 or something for them to tell me that there is nothing they could see wrong and no fix was done.

i don't want to pay them $180 for them to tell me that i need to replace my sensors for an additional $500 or $1000 for both. i could do without the additional $$.

i just wanted them to tell me if they CAN put these height sensor rods back to factory spec, and the service dude says bring it in for a diagnosis.

is this a job/ service that CAN be done??? thanks,

 

Of course they can be set back to the stock settings. These are specified for both front and back sensors in the service manual, including the exact measurements from the frame reference points.

 

great awesome, THANK YOU,, why is lex of annapolis only interested in replacing shiz and not fixing shiz... that shiz pisses me off right there... thank you to you senior vcheng.

 

dude are you serious?? this question was asked numerous times previously (thread count or something to this effect) and i never once saw an answer or response. how do you know this if you don't mind my asking?? wow that means i can most likely do it myself then. thanks for this kick *** response considering the info is correct you may have just saved me a boat load... thanks man,


one more for you then mr. smart guy

what about the headlights... is it safe to say that the factory spec for adjustment is just a straight line all the way across say when parked in front of a wall pretty close up?? or is there supposed to be one higher or lower than the other?? cuz i know the pattern or beam is slightly not straight on a stock vehicle.. something to the effect of -----------/___________ or __________/------------ i forget which one?

 

The left headlight on cars is usually aimed a bit below the horizon to keep glare out of the eyes of oncoming traffic.

 

don't waste your money by given it to the dealership....you can save $ by do it yourself.....there just gonna guess as much as you did....

 

Yeah I know this ^ ^ ^, and now that I know the thread specs there is nothing stopping me, and my lights were barely even doing it this evening so I am confident they r only slightly tweaked, but the dealership guy was talking like they need to replace all kinds of stuff,, yeah if it not my money ur talking about u can go right ahead.

I know every dealership is different, I just wish they would try to figure out what was wrong and how to fix it instead of wait to even discuss the possible problem until the stopwatch of labor charges has started then take ur sweet *** time and decide to replace it instead of fix it..

 

I doubt that the thread count listed in the above post will work for your car. The right way to set it back to factory is to get the service manual and follow the procedure which will involve some measurements of not ride height but suspension component-to-reference point measurement.

 

hmmm, well one way sounds free and one way not so much.. i will try the thread count one first and then go from there.

 

About a month ago, I got so sick of dealing with my driver side jacking up while I'm driving, uneven height for all corners so I brought my car in at local Lexus dealership.

turns out, when I had my car aligned by a local shop, they touch the height sensor rods and it was all over the spec.

Dealership has tested all sensors, found passenger rear sensor not throwing the correct spec. Replaced and put all height sensors back to the stock setting.

Now, I have no more issue of my car going up and down on its own. Car is dead level (visually).

Cost? Expensive but all taken care by the CPO warranty.

Note: I'm on datasystem as well.

 

yeah its that expensive part i'm worried about, cuz for me my sensors may not need replacing at all just readjusting and all they are going to say is well they are bad so you need replace them. i have a connect at a dealership i may try to talk to him and see what he says about it but its like an hour drive over to that specific lex so i don't just feel like driving for the hell of it you know... i'm going to try and adjust myself tomorrow back to the specs that someone posted above, if that doesn't work we will see what is next.

must feel good to have all that stuff done though i'm sure... ^ ^ ^

 

Hey Sojah: You may find the following information useful for your air suspension:

To check air suspension, change from Normal to High and from High to Normal should take between 20 to 40 seconds and change ride height by 30 mm. Automatic Ride Height should be checked by seating 4 people (2 in front and 2 in the back) each weighing 68 Kg, with time to target height being 40 to 60 seconds. When people get out, the vehicle should acheive target height in 10 to 30 seconds.

To check a height control sensor, remove assembly and connect three 1.5 volt batteries in series with positive connection to terminal 1 and negative connection to terminal 4. Stationary sensor reading should be 2.3 volts, and change between 1 to 4 volts at either end of travel.

Front:

Ride Height 115 mm between B and A, where A is defined as ground clearance of lower suspension arm No. 1 bushing set bolt center and B is defined as ground clearance of front wheel center.

Height Control Sensor Link Reference Length: 59.3 mm (2.335 inches) from top of one adjusting nut to the end of the other adjusting nut (i.e distance between the adjusting nuts plus their thicknesses at both ends).

Turning the adjusting bolt by one revolution changes ride height by 5 mm.


Rear:

Ride Height 109 mm between D and C, where C is defined as ground clearance of lower suspension arm No. 2 bushing set bolt center and D is defined as ground clearance of rear wheel center.

The sensor link length is not specified, but moving the installation position on the link on the lower arm by 1 mm changes ride height by 2 mm to acheive the reference height between D and C.

 

wow, this is some pretty high level stuff you gots there mr cheng ^ ^ ^. i am on my way out the door to set them at the visible thread count setting that someone posted up here above and if this doesnt work then i will be taking it to the dealership but i will def print out your previous post and show it to the dealership guys if i have to bring it in. i am not in a position to test the things your post says to test but hopefully the dealership will have the required stuff if need be. thanks for your very detailed and specific writeup. who knew these things were so complicated anyways

 

well i just eye balled it and put them back to the above aforementioned specs (factory), so we will see how that goes. i really should have had a magnifying glass or something cuz those threads are sure hard to count from like 1.5 feet away since i couldn't get my head inside of the wheel well
