Leon Posted November 1, 2011 Share Posted November 1, 2011 In my opinion.... The control arm failed in bending due to the vertical force applied to the LCA by the sway bar. The plate was notched for the tube to be inserted and welded, and right at the end of the notch the section goes from very large to very small, near the middle of the arm, with a force applied near the minimal section. Bad design. If the TC rod doesn't transmit most of the braking force to the chassis, I don't know what else possibly could. The strut resists the caliper torque, but this force is applied to the chassis in a forward direction. The method of attaching the TC rod to the LCA is fine, and didn't contribute to the failure. jt Bingo! We have a winner! Quote Link to comment Share on other sites More sharing options...
camerashy Posted November 1, 2011 Share Posted November 1, 2011 (edited) Any thoughts on these 'ebay jobbies'? They are machined like the arizonaz car ones but no word as to what grade alu 6061 grade, and looking at the arm itself, it appears it just threads straight into the aluminium. But puzzled as to what looks like a weld on the 'U' plate here..

rossman Posted November 1, 2011 Share Posted November 1, 2011 Any thoughts on these 'ebay jobbies'? It looks like it was designed by someone who doesn't understand the loads passing thru the components. The TC components look exceptionally weak.

rossman Posted November 1, 2011 Share Posted November 1, 2011 The control arm failed in bending due to the vertical force applied to the LCA by the sway bar. Agreed, but I would add that the the sway bar loading combined with compression in the LCA caused it to fail. Quote Link to comment Share on other sites More sharing options...
zero Posted November 1, 2011 Share Posted November 1, 2011 But puzzled as to what looks like a weld on the 'U' plate here.. Looks like they welded a nut on the back end of he U for the rod to thread into. Quote Link to comment Share on other sites More sharing options...
