Different Styles Center Links
Tie Rod placement and length is importantIt must be parellel and close to the same length in order for the toe in to stay constant during jounce and rebound
The MOST CRITICAL tire wearing angle
Tie Rod Spring loaded typePivot point for the linkage during turning and suspension bounce Some mechanics over sell by using a large angle headed pliers to test the tie rod end
Tie Rod Sleeve Function To adjust tie rod length
Tie Rod Sleeve
Excessive toe in or toe outInside edge Toe out wears the inside edge Toe in wears the outside edge
Excessive toe in or toe outScuffing wears off the edge of each tread rib.
