Its not bad if you do it in sequence. First time i did it it took about 4 hrs, second time about 1.5 hrs.

Pull Wheels

Get Calipers and Pads off

Soak all bolts with penetration lube such as WD 40, I use PB

Pull Tie Rods

Then:

First thing you have to do is pull pps solenoid. it is located on rack,underneath the steering nuckle and only thing with 2 wires. I used vice grips and it came off fairly easy, unplug it

Next get a line wrench 17mm and disconect 2 big lines behind pps solenoid on rack, note there are 4 solid lines on rack 2 small on front of rack facing the back of the car(do not remove just a waiste of time) I found it easier to break line bolts with the 2 wrench cheater

be sure to have a drip pan ready fluid will pour out

Pull drivers seat all the way up and stick seatbelt through the steering wheel and connect it, then push seat back untill the seatbelt is taught and you cant turn steering wheel.THIS IS IMPORTANT for allignment plus you will not dammage youre air bag and clock spring Disconect steering nuckle,2 12mm bolts.once bolts are out use flat head screwdriver and tap knuckle up untill its off rack.

Remove steering dampining shock Remove the side that has 1 bolt,The other side is part of the mount and cannot be taken off at this point

There are 4 big bolts and nuts that hold rack to frame 2 on left 2 on right take those out dampining shock will be lose and hanging. save the shock and metal clamp

Last is remove the 4 outer transmission mount bolts and remove. Dont worry transmission wont fall. Jack up transmission about 3 to 4 inches. slide rack to the right or in the US left remove 2 rubber mounts then pull out. Removal is complete!

Reverse to install.

would recomend replacing outer tie rods since you are doing all this work.

On the Tie Rods make note of distance from where the threads start on the rack to where tie rod bolt is this will also make it easier to allign

Get a Allignment done

    • 10 years of Lexus design: from spindle grille to spindle body
      After 10 years as a defining style feature of every new Lexus model, the famous spindle grille is undergoing a transformation. In tune with a new era of electrified vehicles, the distinctive shape is evolving into a new “spindle body,” as seen on the upcoming new generation Lexus RX SUV and the all-electric RZ.

      The spindle grille has been an unmistakeable Lexus feature since it was first revealed on the LF-Gh concept model of 2011, the basis for the fourth generation GS executive saloon that was launched the following year. Since then, it has been constantly adapted to suit the character of each successive Lexus model, with different mesh patterns, dimensions and finishes.


      Speaking at the time of the grille’s debut, the then Head of Lexus Kiyotake Ise said: “You should be able to identify a car as a Lexus immediately… Instant visual recognition, for example, is the reason behind our spindle grille. It may look aggressive at first glance, that’s intentional, but it also conveys its boldness with sophistication and elegance.”


      It has progressed to become a hallmark expression of Lexus’s L-finesse design, adopted not only for road-going cars, but also incorporated in the futuristic Skyjet spacecraft created for the Lexus-supported movie Valerian and the City of a Thousand Planets and adopted as a design motif in the Loft, the award-winning Lexus and Brussels Airlines lounge at Brussels Airport.


      Today, the original grille concept is the starting point for a more radical application of the spindle shape in which it becomes an integral part of the vehicle’s overall design. This “spindle body” approach is part of the Lexus Next Chapter design for the all-new RX, where the grille is reinterpreted as a seamless unit that flows into the bodywork. The lower section retains a mesh pattern, while the upper section takes in the lower edge of the bonnet; the Lexus emblems sits at the centre of the spindle’s high pinch-point.


      The same concept has been applied to the RZ 450e. As a battery electric vehicle, this requires less cooling than a car with a conventional engine, so the grille has been dispensed with, giving the designers greater freedom. Nonetheless, the spindle shape remains prominent in a central front panel, finished in the car’s body colour. Its impact is heightened by the adjacent frontal areas being contrast-finished in black, the low bonnet line and more boldly shaped front wings.

      On both models, the spindle generates lines that flow back from the front of the car through the bonnet and headlamp units to create a strong and distinctive frontal appearance, reinforcing the brand-defining ambitions of the original concept.
