    So I know HOW to adjust my panhard, it’s a f-cking hassle but that’s not my problem.. I noticed about a week ago that my axle seems to be off center, poking just a little further out on the passenger side, I had previously adjusted it and had it perfect but obviously something shifted. My question is what would/could cause the shift?

    It’s not a dramatic jump but noticeable if you compare both sides.. I thought I had shocks sagging or something in the rear at first but the geometry would make it poke the other way of it was that so what do I need to check out?

    Did you rock the body of the car several times left right before measurement? I think there are some millimeter flexibility in the bushings.

    I'm not sure, but for exact measurement you need perfectly level ground and the driver seat occupied for weight distribution?

    parked on level surface?
    sometimes I notice one wheel poking out a little then realize i'm on uneven ground

    I didn’t rock it side to side but the poke seems to be consistent every time I park it. I had not contemplated the driver being in the car however..

    I checked it on my driveway so it should be level but I may move it around to be sure.

    What brand of adjustable PHB did u use ? The BMR on car adjustable PHB is easy to tweak. It's made from DOM tubing. The adjustable portion is made from chromolly steel..and resides inboard several inches. Adjustable portion is on the pass side. I can just barely slide under..and tweak the lock nuts, while a helper tells me how far to tweak. Done on a level surface of course. Bounce the rear end of car up /down several times.

    Some adjustable PHB's are at the extreme ends of the PHB..and are a major pita to adjust.

    Hell, it’s been that long since I bought it I don’t even remember. It was on sale but it’s one with the jam nuts all the way at both ends so it’s a hassle for sure, hence why I was curious if I need to check anything else in particular while I’m under there.. I don’t want to have to do it again if I miss something!

    Was the car also lowered? If so, how much, and did you re-clock the bushings of any arms that retained the OE rubber bushings? How full was the fuel tank when you centered the axle the first time? More stuff in the trunk now that wasn't there before?

    It is geometrically possible for lowering past some point to start pulling the axle back toward the passenger side.

    I had to tweak mine twice after initial install/adjustment of adj. panhard. It has since remained centered even after several track days w/slicks.

    And yes, uneven surface can make it appear the rear end has moved.

    Car was lowered on Eibach Pro Kit springs a few years back, didn’t have any issue until about 6 months ago and even then it was just super minor but I couldn’t un-see it. Tweaked it in, was great until just recently so I’ll be tweaking it again. No dramatic changes to anything so really scratching my head on it!

    Maybe your springs settled a bit. Air pressure low in one or more tires. My driveway is pretty level but not perfect and I can tell a difference between my driveway and my garage.
