Suspension needs resuscitated, input please

[SeanWN86]

So I'm looking to fix up my suspension, as I only have ~5/8" gap at my bump stops, and my front axles are pointed upwards(which now have two recently cracked boots). I have also started getting the lean in the rear(very mild), so would like to correct that if possible, but I'm not interested in lifting the rear/truck overall(at this time).

It is a 165k miles pavement-pounding/grocery-gettin/family-road-trips 4Runner, AWD V8. Lives in the Bay Area, where I DD unloaded. Road trips 4-5 annually to SLC, UT, plus any other trips, loaded with just wife and kid(2nd on the way, don't tell anybody yet though) and enough luggage for double that.

At this stage I want to do coil overs on the front so I can raise/lower to get the leveling how I want(and future proof it, for when I can lift it); I'm thinking TC UCA, w/King coil overs.

Question is on the rear; can I use my stock springs w/King shocks, and how would it pair with the front?
It looks like my only other option would be the OME rear coils, 895e(1” lift), is this accurate, any other options to consider? Will these correct/prevent future leaning? And if the only option, for as close to stock height, how will it pair with with the King coil overs?

For a couple months I had front/rear Icon 2.5 shocks with heavier 700 lb front coils with stock rear coils and then swapped to FJ rear coils which net .25-.5 inches (next to nothing but apparently stiffer, I can't say I noticed a difference between FJ and stock). With this setup I was able to 'level' the front of my truck.

Anyway, everyone will tell you to get matching rear springs but I thought it rode just fine, just be careful loading up the rear I guess.

In the back

I have an ICON stage one lift. 2.0 ICONs in back are paired with the dobinson 59-599/220# 1.0 - 1.25" lift rear coils. Like them paired with the 2.5 ICON coilovers up front set @ 2.0-2.15" of lift.

Theres's also the wheeler T12 1.5 to 2.0" and the T13 which is spec'd for the 5th gen but could yield about 1.0" of rear lift. Both share a 200# spring rate.

It sounds like you're on the right track. King suspension front and rear would be an awesome set up. They can custom valve the rear shocks to match whatever coil spring rate you go with. Its key to match the damping of the shocks with the spring rate/stiffness, or else it won't ride like an expensive set up should. Basically if you run softer springs than what the shocks are valved for, it will be over damped. This means there is too much compression damping so it will feel stiff, and too much rebound damping will make the suspension "pack up" on repetitive hits- also making the suspension feel stiff and harsh.

If you're planning on spending $3,000+ on a King set up you might as well get rear coil springs that match the rear shock valving. Give King a call or someone that sells a lot of King set ups- they'll steer you in the right direction.

I run an Old Man Emu set up which isn't as nice as King, but all of the components are designed to work together so it still rides great. You want to make sure that the front and rear suspension work together, ie not stiff up front and soft in the back.

I've already done the LCA from Rockauto, ACDelco, several weeks ago. Because I was going to have to wait 8-10 weeks for the king package, and felt like this was a big culprit to some of my weird symptoms.

I have waiting to be done; TC UCA, King coilovers and shocks, front cv axles/seals/fluid, outer tie rods, SS brake lines, and new 5th gen calipers/rotors/pads.
Waiting on rear springs.

But my steering has just been getting worse and worse. So I took some videos and would like the professional Internet's opinions.

It seems to me like the front LCA bushings are already shot?
That my steering rack is moving more than it should?
And maybe even the bushings that mount the front differential are giving up the ghost??
