Hey All-
New to the YJ/Wrangler world- picked up a manual 1990 4.2, the 4x4 doesn't seem to be working, which I assume is the vac/CAD issue. Also the heater/fan has been re-wired to a electronic switch and nothing seems to change with the damper lever- which from reading some threads, I understand is (was?) also based on the vac system. I do intend to dig into this a little more- but it seems a good bet that some of the vac control system has been deleted.
So my first question is- assuming the spline isn't getting engaged- should I still be able to 'feel' it go into 4hi? Right now, both 2hi and 4low 'feel' like gears, 4hi just seems like it's kinda floating around over there.
Other question is, I mostly plan to use this for some light-duty snow plowing, winter driving (snow or just cold) and some 4x4. Maybe 2k miles a year max. In this scenario, would it even make sense to do a posi-lock (or replace vac), or just do the 180 fork hack?
Last question- she doesn't like to startup in the cold, which is probably 80% of my use/need. I'm going to throw some 5w-30 syn in (no idea what's in there now), but was also curious if anyone recommends a frost plug block heater or other type?
Thanks!
