Forgot to mention beforhand. All the suspension components were checked again by myself and a reputable mechanic and everything looks fine.

I got a chance to pull the driver side coilover and it seems to look fine. Reinstalled it and set it at the same height as the passenger and the car does feel a bit better, but not quite 100%. Going to realign the car again this coming weekend and see where I stand.

IMO, it is entirely possible for a suspension component to be bent, but not be "visible".

Also, keep in mind that the S2k is very sensitive to differences in L and R side tires. Small differences will translate into weird handling quirks, especially tracking differences both on and off throttle.

Sure it is. However, at that point, I'd basically have to start arbitrarily replacing suspension components, which is a tad illogical. Aside from the difference in front camber, which I figure was more a product of the uneven ride height, nothing seems to indicate anything being bent to the point of causing my issues (then again, I'm no expert, just another front yard mechanic lol)

As I mentioned, I already adjusted the coilover on that side and there is a discernible improvement in steering feel. I'm still getting some tracking/tramlining occuring and the steering does still feel a little looser/more numb than it did before the accident, but it does feel a bit better than before adjusting it. I'm going to realign the car this weekend and assuming the caster adjusters aren't frozen, see if the tech can dial in a bit more caster to stiffen up the steering feel. Going to see where I stand after that and if I still have issues, I'll just re-open the claim and explain to the insurance that the car isn't driving correctly and have someone more qualified look over it again

Bumping this one. Drove it today for a bit to run some errands and it was virtually undriveable. Car literally feels as if it's wandering/swaying from side to side. The alignment settings from my above printout aren't perfect, but I can't imagine them being off enough to cause the issues I'm experiencing. Furthermore, I notice the wheel barely wants to self-center when in a turn. I can literally turn the wheel all the way one way or another and it will stay right there and effectively let me drive in a circle without me so much as touching the wheel. Also, I can be driving at any speed and nudge the wheel to the right or left and it pretty much track in that direction. It's literally scary to drive.

At this juncture, I'm sure something else is going on, but I can't seem to find out what the issue is. Going to reopen the claim and have them look over the car all over again :\.

Check the sub frame bolts, both front and rear sub frame. It can't hurt. I fought a "wandering" issue and found 1/4 turn on a few sub frame bolts in the rear. It was moving ever so slightly with very little dip/unevenness in the road, scary.

Maybe you have an EPS problem. Your caster settings are more than enough to self center the steering wheel.

Put the car on stands, and using the WHEELS (not the steering wheel) can you move the steering lock to lock with ease and no binding?

I got hit (more like a nudge) on the passenger front and after the collision shop repaired "everything", I noticed my car would do this exact same thing. I could turn full lock left and the steering wheel would stay there and I could do circles without the steering wheel centering itself. The car would act normally if I turned full lock right. I took it back to the collision shop and they took it to a honda dealer which diagnosed the problem as a bent rack in the steering system. The entire rack/pinion assembly was replaced (under warranty of the initial repair because they didn't repair "everything") and the problem was fixed. Honda said the rack/pinion assembly is not dealer-serviceable so it had to be replaced as a unit.

I'm not saying your system is bent, but is stands to reason that damage of that nature was not detected during one of the many visual inspections of your car. It could be tweaked enough to be causing problems. Also, like Billman said, you might have the EPS checked out. It may simply be an electronic sensor issue and not something mechanical.

Good Luck.

Sounds to me like you have a ball joint that is binding.You will need to disconnect and check them individually to find the one that is binding.I would start with the side that was hit.I have been a technician for 25 yrs. and have seen alot of strange things happen with suspensions. I do know that these cars are very sensitive to good tires. I bought mine with half worn Yoko Proxis tires and it was a handful to drive. When I replaced them with Bridgestone Pole Position S-01s it made a world of difference in how the car drives. Good luck.

Going to give this a shot tomorrow when this fever comes down lol.

I drove it around a bit this morning, and I also noticed that nudging the wheel a bit to the left or right will cause the car to veer in that direction indefinitely until I correct the wheel. At full lock, it'll go in a circle and very slowly and in bursts start to self center. I was able to go in about 3 circles in a big parking lot before it came close to self-centering.

I was going to reset the torque neutral position sensor to see if maybe that helps?

I've been leaning towards something being wrong with the rack as of late. I took it around the block to test it again, and noticed that it gets stuck at full lock when going slow in both directions, but will little burst by little burst try and self center if I speed up and eventually stop at roughly the 10 o'clock and 2 o'clock positions depending on what direction I turn the wheel. I could easily drive in a few circles before it corrects itself though. Also, I can nudge the wheel in either direction and the car won't return to center and will veer off in that direction indefinitely until I correct the wheel. I test drove 2 other local s2k's, and neither of them had that issue.

I already spoke with allstate and explained the situation to them. Going to bring it to a mechanic I trust to go over everything piece by piece.
