I didnt know so i force it in, did scrap alittle mental off the phb end and chassis mount when i force it in. I should be okay. My thrust before was -.18 and i was told by american muscle to get a panhard bar to fix the rear axle offset which i did. I had to make about 1/4 of an inch adjustment on the panhard bar. If anything it should of help, i guess ill need to visit an alignment specialist.

Also i wanted to add that in instruction it says to "It is important to adjust both sides equally while maintaining the spacing difference (the long threaded end should be roughly
35mm longer than the short end)"

what do they mean by maintaining equal space difference?

I slide it in from above. Trying to go in or out from the bottom of the bracket is tight, if that makes sense.

You take it to an alignment shop, they wont know what to do! ..unless someone there is familiar with these cars and about an adjustable panhard...
there is NOTHING to align.
There is ADJUSTMENT, that as described above, can easily be done.

The car won't pull one way or another as a result of this; has nothing to do with steering.

I haven't read their installation instructions, but I think they're trying to ensure that you don't end up with not enough threads engaged anywhere.

Im a newbie when it comes to cars, theres still much to be learned. I find it weird when people says no alignment needed when installing these phb. Doesnt moving phb side to side change thrust point?accuracy going off by wheel well? wouldnt adjusting it on an alignment machine give you the closest 0 thrust.

Norm regarding to the installation instruction that was only part that threw me off. the longer end which is passenger side has same amount thread after adjsuting as driver side.

As long as you get it adjusted, just tighten the jam nuts and lock it all down!

I don't think it's common for people to have to tweak thrust angle when all they've done is swap in an aftermarket PHB and adjust it, but then again it could come down to how sensitive the individual is for a slightly off-centered steering wheel vs the desire to get the axle visually centered.

Do the bushings in your OE PHB look distorted in any way?

oe phb bushing looks fine, why? I work 11 hours a day and tomorrow is my day off, i can finally take it in for alignment. I just find it odd the new phb didnt make my -.18 thrust with oe better, rather worse now. Negative thrust means back wheels are slightly facing left, since i move my new phb more to the right wouldnt that make it better and not worse. bummer

Norm Peterson

I'm looking at bushing deterioration as a possible cause of thrust angle error you had before that might have gone away with the new PHB's bushings/sphericals. I also suspect this as a possible explanation for why people seem to find far more axle shift when they lower their cars than can be explained by triangle geometry alone.

The reference I found ( http://www.ttsroadsport.com/4_wheel_...t_glossary.asp ) differs on sign convention, and according to this a negative thrust angle would be consistent with the car trying to drift to the left (until you correct that by steering to the right).

Good news, thrust is not out of whack rather its now -.03 way better than before. It was previous toe setting that upset the steering.

UPDATE* I had to revist tire kingdom ealier due to steering wheel slightly sitting left while driving striaght down the road. He went under and adjusted the toe setting on both side but he didnt have the reflector on the wheels. He said it wasnt neccessary and sure it would not mess up my spec. Should i be worried? Hes a very knowledgeable alignment specilist from what i can tell and car drives striaght.

Bad news, rear tire slightly cupped, not by shock so they think its the car characteristic or lack of rotation in 10k miles since purchase lol
