I bent the main shaft on my np231. The replacement shaft I bought from a member has the syncro assembly and mine does not. looking at the parts list the syncro gear should work without ony problem but I have 2 questions,
What is the function of they syncro in the transfer case?
Is there any advantage / Disadvantage to using the gear with the syncro?
A little history The filter plugged on my transfer case and everything is a litle gunked up inside tolerences are still decent but the new gear with the syncro is smoother so I will use it if I can. I'm planning to run Royal Purple in it at least for a while to polish things out so It shouldent be a problem. Just to see if there is gear mesh imporvement with the royal purple I'll take wide spectrum vibration readings right after I button things up and again after 10 and 20 thosand miles.
