Just curious if someone can hep me out by describing the symptoms and diagnoses procedure of bad INNER tie rods. The symptoms of worn outers are documented well on the forums (clunking & the 9-3oclock wheel shake to test), but I haven't really read anything about the inners.
From what I've gathered from various youtube videos (of non LXs), a good inner tie rod will rotate smoothly (when disconnected from the knuckle of course) and freely but NOT loosely at the sleeve/joint. In other words it will move in all directions but not be all loosey goosey and will hold the position you leave it in. The last time I had a chance to check this out when I was upgrading my Brembos, I noticed that while mine moved freely, they dropped back down when I wasn't holding them. Is this good or bad?
The reason I ask is this: I have been having road wander (even when holding wheel dead still)/extreme crown sensitivity/horrible bump steer (now even when going straight!)/general loose/disconnected steering feel issues for almost a year now. I am running full SRT suspension w/a front Brembo setup. I recently had a 28pt Pedders inspection. The guys at the shop were EXTREMELY knowledgeable and let me get underneath the car; carefully explaining weakpoints of the LX suspension and showing me first-hand the parts that would be replaced and how it would help mitigate/alleviate each issue I was having. They showed me the new Pedders bits that would go in and demonstrated how soft stock bushings really were and how they compared to their urethane bushings. All-in-all, it was a great experience and quite a relief to finally have my suspension inspected by someone who knows to look for more than just a leaky strut and do the ol' tie-rod end wiggle test.
They recommended:
Radius Rod (aka tension strut) bushings
Lower control arm bushings
Upper control arm bushings
Bumpsteer kit
Their GSR struts/springs (front only) and lower strut mount bushingsWhile I have no doubt that the above upgrades would dramatically improve the ride and handling of my Charger, I have one issue that just keeps nagging me - While they were very helpful in pointing out potential weak points in the suspension & teaching me what could be causing my symptoms... they never actually found anything wrong underneath my car! Now let me say first hand that this is in no way meant to knock Pedders or their shops. The inspection was top notch and very informative and the guys there were great. It just bothers the hell out of me that they found NOTHING wrong. I'm just finding it hard to part with $1500+ bucks to replace a whole bunch of stuff when the actual problem hasn't been located. If they told me "hey, look at this here, this is torn/worn... this is leaking", then I'd feel better. But no torn/visible worn bushings found, nothing leaking, nothing wiggling or loose. Not a damn thing. I would really like to locate some kind of problem before spending so much money. If it was just small/cheap things then I'd have no problem going the trial & error route. But stuff ain't cheap (and deservedly so) and I want to pinpoint something before moving forward.
So... now that you have the background - Back to the original question: Inner tie rods: symptoms & how to diagnose? Please... no outer tie-rod symptoms and diagnoses; Again this has been discussed ad-nausem. Just to reiterate - my symptoms are "road wander/extreme crown sensitivity/bump steer (now even when going straight!)/general loose/disconnected steering feel". Also, I notice that from dead center, a quick 90* turn to the left yields more of a turn than a quick 90* turn to right. Oh, and I have the clunking too. Keep in mind that my 2 front wheels pass the 3-9 oclock wiggle test with flying colors - stiff as a rock. I am aware that SRT shocks do have a bit of clunk but mine sounds more like engine is about to drop on the highway and the front end is going to disintegrate.

EDIT: Oh, and they found the 2 front tires to be wearing on the inside so bad that steel belt was coming out of one of them on the inside. The rears were at about 50% but even. The fronts have been replaced since by Hankook Ventus ST 275/40/20s and an alignment was done yesterday. Everything is within spec. Still experiencing these issues.
