Lx570 rear coil spring spacer install instructions (1 Viewer)

[highfructose]

I didn’t come across instructions clear enough that a novice could do this. I ended up tearing up a bushing as I figured it out. I’m not a mechanic type. It’s outside my wheelhouse.

The reason I wanted to add these spacers is that I’ve got a bunch of extra weight in the back of my lx570 and it’s kind of wallowy on the highway in comfort mode. Also it pogo’s a bit when going over a particularly rough dip near my home (note: this did seem to stiffen my suspension a bit, potentially allowing me to again use comfort mode at highway speeds).

I think most people consider this such a simple procedure that no clear instructions are needed…an outline is enough.

I wouldn’t recommend you use these instructions. I’m not a mechanic…and because you’re lifting a very heavy vehicle up in the air, it could fall and you could die. Pay someone competent to do it or have a friend who is competent do it.

All that said, if you’re going to do it, perhaps these instructions will reduce the chances you tear things up (like I did) or hurt yourself.

1. Jack the side of your car you are working on up and secure it with with multiple stands on the frame
2. Remove tire for the side you’re working. 22mm socket. Your lock for your lug nut is probably in the tool kit in the tailgate of your vehicle. I would recommend you remove the center cap cover on the tire. It’s brittle plastic and it gets chewed up by the socket as you remove the lug nuts…also place it somewhere out of the way…they’re like $50 a piece.
3. Put a Jack (I used 3 ton) under shock bracket but not touching shock bottom
4. Remove nut at bottom of shock and nut at top of sway bar link (image is of the location of the sway bar link but to remove. I would not recommend you remove the bottom one. It’s problematic if you do so).

1. Jack the axle up very high…ahc shock should slide off the bottom bolt by hand.
2. Now slowly lower the axle all the way to the ground…you’ve already removed the things that keep the axle from going down too far…the sway bar and the shock…I used two jacks here so I could get the main one off the bottom of the shock mount.
3. You may be able to get the coil out by hand now. Maybe not though
4. If not, you can press on the axle downwards and it’ll bounce a little bit and that’ll give you enough slack to pull the coil out and the plastic thing on top of it out.
5. Place your spacer wherever it’s supposed to go relative to the coil and replace the coil (I could find no clear instructions on this on this)…then place the entire coil/spacer/bump stop? Back where it started. the bottom of the coil orients a particular way.
6. Put your jack on the axle, proper, as though you’re going to change a tire…so it’s clear of the space your tire will be going once it’s lifted.
7. You only need to jack the axle maybe a foot off the ground before you can slip the shock over it’s bolt…press slowly and firmly on the shock and it will go up to sort of meet the bolt. Slide it over the bolt slightly. I then used a block of wood to tap the shock down its bolt.
8. I put the bottom shock bolt on at this point
9. Now you’re jacking the axle up and trying to align the sway bar link with the perch it bolts into on the frame

Once that’s tightened, put the tire back on.
I think the lug nuts should be at 97 lbs

Here is my thread in same topic for LC ( no AHC):

Rear coil spacer install procedure confirmation/questions

Planning on installing my 30 mm spacers I got from Trail Tailor on my OME BP-51 rear suspension. Looks straight forward enough but I wanted to get any advice and confirmation of what I believe the steps are: 1. With truck on level surface, back out the KDSS screws 3 turns to equalize pressure...

Another thread with some good info:

Realtime help needed: Reconnecting rear sway to KDSS

I'm installing air helper springs in the 200. Bags are in, springs are in, KDSS valves are out 3 turns each. The problem is the KDSS lever arm that connects to the rear sway bar driver side is fully extended down and takes a tremendous amount of force to lever up, impossible to do while trying...

In this on is a pic of how I disconnected the sway bar on passenger side. I did disconnect it from the top and used a bottle jack to raise and lower it.

Also I found it all much easier with both rear wheels removed but I am also very careful when working under 7000lbs of vehicle supported by stands. Suspension work is particularly dangerous. I put the wheels I have removed under the frame rails as a precaution. I also lay 2x8 on top of the wheels to get at close to them as possible. I have even laid a steel Ibeam across the wheels. I just like having something thicker than me under the truck.

I considered removing the opposite tire to make the suspension easier to see saw. Might have been more straight forward that way.
