No, only impact damaged arms. People have been worried about the alumunum lower control arms thinking they can't be strong enough, but I remember hearing the same concerns when they started using aluminum wheels on trucks in the 1970's.

flanaganman Posted December 16, 2007 Author Share Posted December 16, 2007 heres some pic ive never worried about the arms before never gave it that much thought just a big change from all the trucks ive owned before. 69 71 94 ranger 96 f150 97f250 2001 f150 in the 2nd of the pic you can see its cracked in the casting seam you can see where it had been ground. on a mac you can drag the pic to the desk top and zoom in on it.

F250 Posted December 17, 2007 Share Posted December 17, 2007 I see your point. Are you running a lift with oversize tires or all original? Quote Link to comment Share on other sites More sharing options...
flanaganman Posted December 17, 2007 Author Share Posted December 17, 2007 (edited) no on the lift. truck came with 18s p275/65 changed to a 285/60 18 i cant help but think there's something wrong with the casting im taking it in on tuesday so ill get a better look at it and some better pic. im hoping the ex-warranty will cover it. the arm is $250 plus tax hope its just one thats bad. i still cant help but think im not the only one thats had this happen or maybe people should be taking a closer look at them.

Have heard on the 09 f-150 they have changed the lower a arm to stamped steel as I am sure it would be cheaper than alum.??? Quote Link to comment Share on other sites More sharing options...
