STEERING WHEEL OF THE VEHICLE STARTED SHAKING BAD AROUND 500 MILES. IT IS A CONSTANT PULSATION LEFT/RIGHT. HAND/ARM PAINS AND ACHES WHILE TRYING TO HOLD THE STEERING WHEEL. THIS IS ALSO TERMED AS SHIMMY / STEERING WHEEL SHAKE PROBLEM AND SUBARU HAS 2 TSB IN EFFECT 05-50-10 AND 05-48-10. 05-50-10 (RFB) WAS PERFORMED. THAT DID NOT FIX THE ISSUE AND THE STEERING WHEEL STILL CONTINUES TO SHAKE. THEY HAVE NOT YET SCHEDULED 05-48-10 (BUNCH OF PARTS REPLACEMENT) FOR ME, BUT I HAVE A CASE OPENED WITH SOA (SUBARU OF AMERICA) - CASE # [XXX] IN ADDITION, DURING LONG MODERATE-SPEED TURNS LIKE HIGHWAY RAMPS, HIGHWAY ENTRANCES THE STEERING WHEEL PULSATES. IT FEELS LIKE THERE IS A "FREE-PLAY" GOING AROUND MID-TURN. ALSO, I WOULD HAVE TO HOLD THE STEERING WHEEL TIGHT OTHERWISE IT TENDS TO GO AWAY OR FLOAT. FROM WHAT I GET FROM OTHER OWNERS WHO GOT THIS TSB DONE, THE PROBLEM HAS NOT BEEN FIXED. SUBARU SEEMS TO BE MASKING THE PROBLEM RATHER THAN FIXING THE PROBLEM. [REFER LINK : HTTP://WWW.SUBARUOUTBACK.ORG/FORUMS/108-STEERING-WHEEL-SHAKE-ISSUES/] I AM YET TO GET THE MAJOR TSB DONE. SOA SAID PARTS WILL ARRIVE AT DEALER THIS WEEK. I WILL FOLLOWUP WITH MY DEALER ON THIS. I WANTED TO REPORT THIS AS A CRITICAL ISSUE SINCE I DO NOT BELIEVE THIS TSB WILL FIX MY PROBLEM (BASED UPON EXPERIENCE FROM OTHERS). PLEASE HELP TO ADDRESS THIS ISSUE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
