I have a rubbling noise that starts around 50 and somewhat goes away at 60? I guest that it was the SADS, because I can roll the shaft a little left and right easily. In reading some of the SADS problems, no one mentions the speed at which a noise/rubble starting at a set speed. I'm not a tech, but I can read and follow directions. I have already replaced both front shocks, KYB GR2 and the rears, Monroe Sensatrac. Added an Addoc rear sway bar, boy does that help on my rural gravel roads! Also replaced the front differental, via my Toyota Shop Manual, Da Bible!! Updated the Stereo with an Eclipse AVN 726E and added wrecked Lexus Speakers from a 460LS. Always have my Escort 9500IX on ALL THE TIME! Any ideas on the noise/rubbling?? Thanks
