I installed my lift a week ago. Everything was fine until I notice a slight lean to the right maybe 1/2 inch. So I researched and ended up using Radflos instructions to level the truck. I loosen the valves and wiggled it side to side. Tighten up the 2 valves now the lean is worst. Whats wrong ? The truck does look pretty with this drastic lean. Thanks guys in advance for your feedback.:der:


left side


right side

I'm going to guess your driver side coilover needs to come down a bit. Strange to have driver side up any other way with your setup.

How level is the front?
 
the front is off also about 1 inch. The coil overs from Toytec came label Driver Side Passanger side. To their specs. Nothing was undone on the coils? I am clueless and bummed out on how to correct this.:eek::eek::eek::eek:
 
Valves? Are you talking KDSS? If yes, you probably screwed up. Do not touch the KDSS unless you really know what you are doing. If not KDSS, aren't the coilovers adjustable? Adjust it and be done.
 
The 4Runner normally has a driver side lean due to the gas tank and battery being on that side. Did you have a full tank when you installed the lift? Did you level it out when you installed the lift?

If yes to both questions, and if your tank is empty now after a week of driving, the truck will lean to the passenger side because you cranked the driver side coil too high.

Okki
 
Honestly, suspension adjustments are not uncommon during initial phases. I had to lower my driver side 3/4 of an inch after a week in Moab. It can be as simple as how things settle etc. You should have a spanner wrench to simply crank down the front CO. My guess is being 1 inch high is a lot of what we are seeing! Sometimes they get it wrong at the lift company on presets. Totally normal.
 
The 2014 trail actually leans to the passenger side about 1/2 inch from the factory. It sounds like Toytec took into account the traditional driver's side lean, when 14's with KDSS are the opposite. The result is an exaggerated right side lean due to increased preload on the driver's side that is already high. I would suggest readjusting your coilovers to achieve level. The only problem is you will likely need an alignment after the adjustment. Hope this helps.

adjusting the front coils will it level the rear also ? I have no problem re align it. I got lifetime alignment with Firestone.

This would explain it! 10-13 had driver side lean so they have it preset to fix that. They only make one lift version so you most defo need to crank it down quite a bit! That and crank up the passenger. Prop about opposite of what it was set at from factory. It is pretty easy to fix though. You will need an alignment. I've had so many. Really need to do the Firestone lifetime alignment deal...

so should I crank up the right side first ??? to level out with the left ??

You really should make sure that you don't go too high and make the cv angles so extreme. If you go up on the passenger you want to go half way to level and then drop the driver to level. You can lay a long level on the hood or carefully measure from center of hub to fender. [MENTION=55815]Okki[/MENTION] has directions and measurements in his build. He did all the hard work of documenting so you don't have to worry about that. Tried and true!

Yes, it will to some degree. Toytec offers a rear spacer (pretty sure it's made by OME) that worked pretty well for me to correct the right side lean on my stock '14 TE.

I will crank the right side up and bring the left down a little bit. If it is still way off I will look into the rear spacer from toytec.

Maybe I am not too smart but let me see if I understand:

1. You lifted the truck and it had a slight lean, just like almost every 4Runner lifted or not.

2. You screwed with the KDSS, something you know absolutely nothing about, to correct the lean that most everyone already has, just because it looked "simple" to do.

3. Now that you have screwed up the KDSS calibration and made the lean worse, you are going to fix it by adjusting your suspension up on one side?

Did I get this right? If I did, this is wrong on so many levels.
Dude, bite the bullet, take it to a Lexus or Toyota dealer and have them calibrate the KDSS for you. If it costs $500 then let that be the cost of a lesson learned to not go messing with stuff you don't understand and pay it gladly.

Notes:
1. Quick story: I have been known to put dummy valves with very prominent adjustments that are easy to find on our machines. The adjustments are not connected to anything but gives people who know more than me (you know, the "engineers" that did not finish high school nor take even a basic algebra class) a place to "adjust" the hell out of something and leave the real adjustments that could really screw it up alone. No, Toyota does not do this but they should.

2. Pretty sure your instructions identify a "shutter" valve but in reality it is a "shuttle" valve. If you opened the mis named valves too far it could have ruined your KDSS.

This is why I never buy a used vehicle.

Somehow I missed the fact that the KDSS was messed with in this lift install. If that is the case, the engineer is correct. Don't try and fix it on your own. I does sound like the CO will need to be adjusted but you need to have Toyota get the KDSS correct! I should have read it closer. Lesson learned. FWIW, I have made similar mistakes (lucky not with the runner), and it makes sense never to mess with factory calibrated parts in an attempt to correct other self-inflicted (aftermarket lifts, etc) unless you are wiling to pay to have it fixed or you really do have technical knowledge of what you are doing (I know I don't when it comes to this).

In other words, take the engineers suggestion seriously.

So every 4runner that has the KDSS system and has a lean to one side due to a aftermarket lift has to be taken the the dealer for the re calibrations of the system ?????

You don't need to go to the dealer to have your KDSS fixed. As long as you didn't open the valves too far, you're fine. How do you know if you opened it too far? The bolt shoots out and spits fluid from your KDSS system everywhere. You took the right steps and all you need to do is adjust your coil overs and get an alignment.

By the way, the use of a spacer on one side is the fix toyota is using for the Prados that have the same problem, all be it more of an exaggerated lean. In a perfect world the dealer would drain and refill and pressurize the KDSS system, but dealers will not do this unless there is greater than 3/4inch of lean. Some toyota dealers apparently aren't even able to do this and send you down the road to the lexus dealer.
