a level ride.....the endless search

[Lamer]

after installing the YY/YB tundra coils and bilstein 5100 struts up front, and OME890 springs and bilstein 5100's in the rear I have had an unyielding lean to the drivers side.

my first attempt at fixing was to remove the rear springs and make sure they were on the correct side.....they were not and I thought this was the easiest fix in the world. I swapped the springs, (taller spring on driver side) hoping for a level ride. didnt happen. it corrected the lean by maybe 1/2"

this morning, I removed the panhard bar to see if there was any tension/compression that might skew the resting position of the 4runner...sadly there was none! I removed the bolt and the bar was under ZERO tension/compression, it was loose as a goose!. which is odd because the rear axle is offset towards the passenger side!! (see pics) (does that mean something is up with my control arms? the bushings all look good)
DRIVER SIDE, PASSENGER SIDE

,

,

current measurements from the ground (tires are all 38psi, and 1/3 of a tank of gas)
Driver-Front: 38 3/4" Pass-Front: 39 1/4"
Driver-Rear: 39" Pass-Rear: 39 3/4"

Tundra Yellow/Yellow is on the drivers side,
Tundra Yellow/Blue is on the passenger side.

im tempted to switch the fronts and see what happens...:wtf:

I purchased a panhard correction kit from [MENTION=28464]eimkeith[/MENTION], hopefully arrives this weekend. that should center my rear axle. but it wont solve my lean!

None of this makes sense and its driving me nuts!

Looking for a friend to point out something I am missing

A pretty important thing to do when you change ride heights is to reset all the bushings.

Loosen all 5 links (both ends) in the back, bounce the truck and see if you can get the axle to re-center itself at least somewhat. That will also increase the longevity of those bushings since they won't be loaded in their static position anymore.

You'll also want to check for bent lower links.

Measure from the center of your hub, to the bottom lip of fender.
More accurate.

You definitely should not be worrying about a 3/4" or 1/2" difference in height from left to right. The difference in weight on the driver side from a full tank of gas to an empty tank is over 150 lbs. To expect the truck to be perfectly level is not really a very reasonable request. If it bothers you that much, you could get some coil spring pads to put above the coils or invest in adjustable coilovers.

Are you sure you have the fronts on the right side?

That much lean with 1/3 a tank of gas would drive me nuts too. Mine site level on a full tank.

Maybe you need to bump the front drivers up one notch and get a trim packer for the rear, but I would think it's possible to get level on springs alone...

right! i have the YY spring on the drivers side, YB on the passenger side. which should equal a level ride. the lean is worse with a full tank.

I did a quick search for "tundra yellow/yellow coils" and a few hits show up. The first 3 I looked at seem to say that yours might be backward. Might be worth a look yourself...

interesting, until now, I havent come accross any that say YY is passenger side. ill have to give toyota/TRD a call but it might be worth it to switch mine up this week and see what happens.
