b'Squaring Your SteeringLets taLk steering Box systems - continued Step 2. You will want to get a pitman arm (the arm that goes on the splines of the steering boxblue dotted oval) and the idler arm (the arm that bolts to the passenger side frame railgreen dotted oval) to have the same length arms. Sometimes they come that way from the factoryoften not. Its not uncommon to see the idler arm and inch or so shorter or longer than the pitman arm.See example of a 5 & 6 arc in the illustration to the left. The arc is very different, but those arms are only 1 different length .If the idler arm & pitman arm are different lengths, the ends of centerlink will be on those different arcs. It can not stay a true 90 to the chassis. Your car willif it doesnt alreadysteer differently & handle differently on left & right corners. Look again at the photo in the upper right to see the relation of the idler arm to the pitman arm.If the length of these two arms is differentyou have issues. If their location of their pivot axis (purple dotted line in the photo to the right) differs from each otheryour centerlink wont be a true 90 to the chassisand you have issues. If the angle of their pivot axis of the steering box & idler arm shaft are differentyou will have issues.OK. Lets fix it! Your new AXT-STAR Steering System comes with all the correct components to create amazing steering. But you have work to do.The Howe or Wenteq Roller Bearing Idler Arm & Howe or ProForged Pitman Arm thats included in your package are the same length. Both theXX Howe or Wenteq Roller Bearing Idler Arm are adjustable for height to make getting the centerlink level & bind-free easier.The AXT-STAR centerlink is almost magic. It allows you to relocate the inner tie rod pivots up or down, inward or outward & even forward or rearwardto achieve amazing steering. Step 3. What most folks dont think aboutis when they lowered their muscle car significantlythe steering linkage & inner tie rod pivots lowered as well. But your outer tie rod did not. To get your bump steer curve smooth again we cant just lower the outer tie rod point alone. Were below the proper axis & need to raise up the inner tie rod pivot point. We also need to move the inner tie rod pivot point outward as this helps the bump steer curve even more. RSRT provides you with baseline dimensions for your inner tie rod pivot points. You will need to do a final bumpsteer to get it perfect, as the OEM tolerances varied. 389'
