2002 Lexus IS Suspension Problems

I WOULD LIKE TO REPORT A PROBLEM WITH THE LEXUS IS300 MODELS 2001-2005. THERE IS SOME TYPE OF DEFECT IN THE FRAME OR FRONT ARM BUSHINGS THAT CAUSE EXCESSIVE WEAR ON THE FRONT INNER TIRES. DESPITE THE CAR BEING REGULARLY ALIGNED, UNEVEN AND EXCESSIVE TIRE WEAR CONTINUES TO OCCUR. TIRES WILL SOMETIMES LAST LESS THAN 8,000 MILES AND CAN WEAR DOWN TO THE STEEL IN THE INNER SIDES. THIS IS A COMMON OCCURRENCE AND COMPLAINT AMONG IS 300 OWNERS. AS FAR AS I KNOW, THERE HAS BEEN NO FIX FROM LEXUS AND CAN LEAD TO POTENTIAL BLOWOUTS ON THE FREEWAY DUE TO TIRE FAILURES. PLEASE ALSO SEE THIS MESSAGE THREAD DOCUMENTING SOME OF THE PROBLEMS: HTTP://MY.IS/FORUMS/F89/ALIGNMENT-WOES-STOCK-SUSPENSION-NEED-INPUT-390629/. *JB

PROBLEM STARTED WHEN CAR WAS IN FOR REPAIR OF WHEEL ALIGNMENT WHEELS GOT STOLEN FROM DEALER COLLISION CENTER LEXUS NOT CAR GOES OUT OF ALIGNMENT WHILE DRIVING ON A ROUGH ROAD WEARING OUT TIRES COMPLIANTLY ABOUT 3 SET OF TIRES REPLACED

TIRE WEAR AND ALIGNMENT PROBLEMS ON 2002 LEXUS IS300. *BF THE FRONT END MADE A LOUD SOUND OF ROLLING MARBLES. THE DEALER SUGGESTED THAT IT WAS A NORMAL SOUND AND THE FACT THAT THE BRAKES HAD SETTLED THE NOISE WOULD BE HEARD. *SC *JB

THE FRONT TIRES AFTER 19.500 MILES INSIDE EDGE OF TIRE DOWN TO STEEL BELT. OUTSIDE EDGE OF TIRE LOOKED BRAND NEW. CONTACTED DEALER AND THE THE DEALER INSPECTED THE CAR. THEY RECOMMENDED REPLACING THE TIRES AND ALIGNING THE FRONT END AT A WHOPPING FEE OF $732.00 AND TOLD ME THAT THIS WAS NORMAL TIRE WEAR FOR 19K MILES. I TOOK THE CAR TO TWO DIFFERENT TIRE SHOPS AND WAS ASSURED THAT THIS IS NOT NORMAL AND THAT A NEGATIVE CAMBER OF THE ALLIGNMENT WOULD CAUSE THIS TYPE OF WEAR PATTERN. I DO NOT DISPUTE A TIRE OF THIS CALIBER WILL WEAR QUICKLY. THE WEAR PATTERN IS WHAT I DISPUTE. THIS CAR HAS AN ALLIGNMENT PROBLEM!! I PURCHASED TWO NEW YOKOHAMA TIRES WITH THE SAME SPECKS AS THE ORIGINAL BRIDGESTONE TIRES AND HAD THE FRONT END ALLIGNED AND WILL MONITOR THE WEAR VERY CLOSELY AND REPORT BACK MY FINDINGS. *AK
