Hi All

I installed the TRD TTUE suspension kit in my FJ this past weekend. The front shocks come pre-set on different "notches" supposedly to correct the driver's side lean. I also installed new rear springs that aren't part of the kit.

When I measured the clearance between the fenders and tires, the front left and front right were pretty much equal. However, my driver's side rear is sitting a whole inch higher than the passenger rear. I've heard of driver's side lean but anybody else experience passenger side lean?

I'm wondering since these are new springs if I just have to wait for them to settle a bit. Just as with the OE springs, I believe the driver and passenger side are the same.

Or have I messed something up at the rear? The rear coils are properly seated at the bottom, but it's hard to get a good look at the top (where the spring seat insulator touches the body). When I do glance up there, I see a "less dusty" patch of body towards the front of the spring making me think it needs to be pushed forward slightly. But from what I can tell, the passenger side looks the same.

Any thoughts (or reassurances!) would be much appreciated

Thanks!

Tank full or empty?

I'd say around 3/4 full...
I never noticed any lean before but then again this is the first time I put a tape measure to it

what rear springs did you use. i recently changed my rear to Toy Tec super flex HD due to the fact that with my RTT on top and loaded for camping i needed the heaver springs. when i first did it the passenger side was 1" higher but after i put some miles on it and they settled they are within 3/8" now.

And this helps how?



I recall that there were a few spring retailers who had separate springs for the drivers side and passenger side (off set drivers side lean), knowing the brand you purchased could help determine that.

Did you check that the rear springs are seated correctly. The bottom end of the spring should sit in the pocket/indent that is toward the front of the axle.

Hi Guys

I got Eibach Pro Truck springs. I contacted them a while back asking about application and spring rates (they don't publish any info on these online) but never got a response back. The instructions (or useless sheet of paper, rather) that came with them didn't mention anything about a side designation (driver vs passenger). And the two springs looked identical side by side. Even if the springs are different and I mixed them up, I'd expect it to cause the driver's side to sit lower. But mine is the exact opposite. I know I asked for a lift but I meant on all four corners!

I can confirm the rear springs are properly seated on the axle housing mounts; I did rotate them to fit up against those pockets on the mounts. What I have a harder time seeing is if they're properly seated at the top. The spring seat insulators sit in shallow depressions under the body, and if I miss those then it would cause the spring to sit higher than intended. But from what I can tell both driver and passenger sides look the same. And that depression looks to be under an inch so I wouldn't expect to get a whole inch of difference even if it were slightly misaligned.

I'm planning on getting the alignment done this weekend so maybe I'll just ask the guys at the dealership to nudge the tops of the springs as needed

I guess it helps to know I have at least one friend:wink

Just to clarify, my rear driver's side is sitting HIGHER than passenger...

And apologies if my sarcasm from before didn't get through. One of the downsides of using just text I guess

I did search through a lot of threads (well before installing the shocks and springs) but they all seem to discuss how the driver's (heavier) side sits lower. And I can well understand the reasons for this. I'm at a full tank now, pretty sure I have a battery installed, it's been four days since installation, and that one side is still sitting an inch taller.

On the plus side, I drove the FJ 40 miles to work today and made it safely! I had the occasional steering wheel wobble on the highway, but that was there before. Handling felt good and I couldn't sense any abnormalities over bumps or around corners. Actually I didn't feel the bumps at all. I'm thinking I'll just throw the old shocks and springs into the passenger side cargo area to see if that will help them settle a bit.
