2001 Freightliner Century Class

THE LF CORNER OF THE CAB IS OUT OF SQUARE ABOUT 3 INCHES. THE ALIGNMENT SHOP SAID THE FRAME IS STRAIGHT AND THE PROBLEM IS IN THE LEAF SPRINGS, WHICH ARE WORN OUT. THEY BLOCKED THE SPRING 1", AND WHILE THE CAB NOW SITS SQUARE (YES, THEY ALIGNED THE FRONT END TOO, OF COURSE), THE PROBLEM IS THE TRUCK FEELS FUNNY TO DRIVE.

SO I TOOK THE TRUCK BACK TO THEM AND THEY LOOKED UP THE RECORD AND THEN BEGAN A SONG AND DANCE ABOUT HOW IF IT HAD BEEN REPORTED INSIDE A YEAR", YADA, YADA. I WONDERED OUT LOUD IF PERHAPS THE WRONG SPRINGS HAD BEEN INSTALLED ON THE TRUCK (CHATTING WITH THE SHOP FOREMAN) THINKING THEY MIGHT INVESTIGATE AND RECONSIDER.
