Sooo I bought my FX35 a few months ago w 45k miles, have noticed the wheel shaking around 60mph since day 1. Replaced all pads and rotors (they needed to be done anyways) and had a Road Force balance (20" OEM wheels). Three out of four tires were able to be "road balanced," the fourth still couldn't be fully balanced. Shaking improved, but then I added 25mm spacers all around....
Shaking returned with a vengeance. Not only that, but a loud grinding noise immediately started coming from one of the right side spacers. The noise only occurs when I take a hard right turn, but only at low speeds. It sounds exactly like what you would think it sounds like if the hub centric ring was rubbing. Whatever it is is definitely due to rotation of tire as I can hear variation in the sound as the tire turns.
So this morning I took off the wheels and re-torqued the spacers and wheels (they had not worked themselves off at all - were still torqued at 80lbft). I sanded down some of the rust on the hub and inside of the wheel just to make sure everything was sitting flush - still makes the grinding noise. While taking off all the wheels, I also tightened the rack bolt according to the big writeup on this forum - after three successive adjustments, it made the shaking stop!! However, the wheel doesn't automatically return to center, maybe 90% on its own. So my questions are;
1. What the hell is the grinding being caused be the spacer?? Any ideas?
2. For those that have done the bolt tightening for shaking, once it was done, did the overall steering feel 100% normal minus the shaking? Or did it feel tighter? Right now, I have no shaking, but the steering wheel doesn't return to center automatically even though it gets most of the way by itself. Should I be worried? In other words, if the steering feel is not dramatically altered and wheel returns to center ALMOST all by itself, am I okay?? I can back the bolt out a bit to see if I can hit the sweet spot, but want to know what to expect in terms of long-term steering feel...
