How to Assess Timing Chain Wear on 2005 Jeep Grand Cherokee?

You should remove the timing chain cover before measuring wear. Turn the engine clockwise as far as possible until the tensioner piston is fully extended. The distance between the secondary timing chain tensioner housing and the step ledge on the piston should be less than 15mm (0.5906 inches). A second chain should be replaced once the measurement goes higher than the specification.
