Sagging lift after 3 months with Toytec 5100 Bilstein kit

[tnine]

Hey all,
I had this kit installed by Les Schwab tires 3 months ago.

3" Lift W/ Bilstein 5100 Height Adj Coilovers FJ/4Runner

It's been performing great, until last week. I've been doing some slow off roading. I deflate my tires to 18PSI, and I'm moving at no more than 5mph through the national forest roads in the CO mountains, so I'm not beating the hell out of my rig. However, I do have some points where I have high articulation in the wheels.


After each drive, the drivers rear wheel well seems to be getting closer and closer to my tire. I measured it today, my drivers side is 2 1/2 " closer to my wheel fender than the passenger. I'm concerned I have a defective spring or shock, but Les Schwab says they're unable to find an issue. I've taken everything out of my 4runner to ensure it's not weight in the cabin, and I'm still experiencing the issue.

I'm not an expert, so any help/advice/guidance anyone can give me on what could be the cause, I would really appreciate it. I'm not sure how to proceed, I'm less than impressed with the way my new suspension is performing, and getting increasingly frustrated that they can't find the cause.

Thanks,
Todd

Kdss or no? Full tank of gas?

Blown shock wouldn't cause that. A bad spring would. Crawl under it and measure from bottom of spring to top on each side?

Take a look under it and make sure that one of the springs hasn't come unseated. If you've been flexing it like that, it's possible. Good news is that it's an easy fix. And check both sides. If the passenger side spring is being held up on something causing it to increase the lift on that side, it'll obviously change the height relative to the other side.
