I have a 2003 Taurus with the pushrod Vulcan. I am getting the "chirping" noise which indicates a worn camshaft synchronizer. I plan on ordering the Motorcraft part as well as the Dorman part (for the alignment tool). My question is how does that tool actually get the synchronizer aligned. I have seen in previous posts a diagram showing the alignment of the arrow on the top and then sweeping it 38 degrees once the teeth are meshed. I do not however understand how you measure that 38 degrees or if the tool only lets you turn it that far when you get to the correct point. I really would like this explained to me like I am 3 as I am confused by this step. I do have automotive repair and restoration experience, but this is baffling me for some reason, as the other posts indicate that this is a realatively straight forward repair. The mechanic in town is quoting $350 for the job with parts. Thanks.
