2003 Lexus LX 470 I have replaced upper and lower control arms driver side and all four sway link now the SUV acting up strange with the height control system its on low and not going on a normal setting i do not know the sensors locations of height sensors and how to adjust them and this is the first time i have worked on lexus truck and i do not have any online subs or manual for this SUV

check the ball joints

Upper and lower ball joints. Control arm bushings bad. or both.

What noise? And year and make of car?
A clicking noise on turns is a worn CV joint on the axle shafts. A grinding noise at one of the wheels could be a wheel bearing. Worn brake pads may cause squealing, screeching other high pitched noise.

General Description
The front suspension allows each wheel to compensate for changes in the road surface without affecting the opposite wheel. Each wheel independently connects to the frame with a steering knuckle, ball joint assemblies, and upper and lower control arms.
The control arms specifically allow the steering knuckles to move in a three-dimensional arc. Two tie rods connect to steering arms on the knuckles and an intermediate rod. These operate the front wheels.
The two-wheel drive vehicles have coil chassis springs. These springs are mounted between the spring housings on the frame and the lower control arms. Double, direct acting shock absorbers are inside the coil springs. The coil springs attach to the lower control arms and offer ride control.
The upper part of each shock absorber extends through the upper control arm frame bracket. This bracket has two grommets, two grommet retainers, and a nut.
A spring stabilizer shaft controls the side roll of the front suspension. This shaft is mounted in rubber bushings that are held by brackets to the frame side rails. The ends of the stabilizer shaft connect to the lower control arms with link bolts. Rubber grommets isolate these link bolts. Rubber bushings attach the upper control arm to a cross shaft. Frame brackets bolt the cross shaft.
A ball joint assembly is riveted to the outer end of the upper control arm. A rubber spring in the control arm assures that the ball seats properly in the socket. A castellated nut and a cotter pin join the steering knuckle to the upper ball joint.
The inner ends of the lower control arm have pressed-in bushings. The bolts pass through the bushings and join the arm to the frame. The lower ball joint assembly is a press fit in the lower control arm and attaches to the steering knuckle with a castellated nut and a cotter pin.
Ball socket assemblies have rubber grease seals. These seals prevent entry of moisture and dirt and damage to the bearing surfaces.
Four-wheel drive models have a front suspension that consists of the control arms, a stabilizer bar, a shock absorber, and right and left torsion bars. The torsion bars replace the conventional coil springs. The lower control arm attaches to the front end of the torsion bar. The rear end of the torsion bar mounts on an adjustable arm at the crossmember. This arm adjustment controls the vehicle trim height.
Two-wheel drive vehicles have tapered roller sheel bearings. These bearings are adjustible and need lubrication.
Four-wheel drive models and RWD Utilities have sealed front-wheel bearings. These bearings are pre-adjusted and need no lubrication.
Heat treatment may create darkened areas on the bearing assembly. This discoloration does not signal a need for replacement.
Hope this helps?

Issue with Logic Air Compressor Device... Check For Fuse Burn Under The Hood On Driver Side On the Fuse Box Panel..Check on the Cover for Fuse Instruction under Air Device ..or Compressor
good luck

Is the suspension fluid low. If it is, try first to add specific Suspension Fluid for LX470. It is part number 08886-01805 and any Lexus Dealer would be able to look up. Cost about $ 30 it comes in 2.5 Liters. If driving at higher speeds it is normal for it to drop just a bit and resume to balanced height when parked.

you have a failed height control sensor. there are two on your vehicle in the rear. they need to be removed and checked for being frozen and or corroded inside.
75% of the time it is the left rear(driver side). on an 03 it will only be covered if you have an extended warranty.

jack the truck up so tire are off the ground then get and 3 or 4 foot pry bar or strong pipe and put under tire lift up on bar if the tire moves up and down replace balljoints of not check for bad bushings on your shocks sway bars sway bar end links upper and lower control arm if equip.

is it a nosie your talking about ? if so check the sway bar links make sure they are tight and not cracked or worn in anyway, then check upper control arms as well as tie rod ends. I have seen so many people try to replace everything for a noise and it was the tie rod end! they are very sneaky and can sound like a control arm. same with the sway bar links.you can take a jack put it under the control arm jack it up to where the tire is barely off the ground take a pry bar or strong long bar put under the tire and lift up & down while someone looks under at suspension parts you can also buy a automotive stethoscope for like 10$ to listen to each as you do that. most part stores sell them.
