I have not serviced the rear differential in my 1998 Ranger 4X4 with a manual transmission since 2008 and about 25,000 miles ago - current mileage of 122,000 and owned since new and not leaking or making any unusual noises. How often should you service the differential, especially since it has not been driven a lot in last 12 years and mostly in town driving? Also, which is best - a paper or rubber cover gasket and is synthetic gear oil best option for differential or is it more likely to leak with the high mileage on Ranger? The fluid in transmission was drained and refilled with Dextron V conventional fluid in 2/17 with 115,136 miles.
Also, check engine light PO420 (Catalyst Efficiency Below Threshold on Bank 1) has been coming on and going off 3-4 times in last year and last 2-3 years. Turned off code in 8/19 and came back on 4/20 and went back off 8 days later, came back on week later and just went back off on 9/15/20. I replaced 2 precat oxygen sensors in 1/19 with 118,000 miles after PO153 code kept coming on and off and that code has not reappeared again. Will I be able to pass inspection when code disappears and before it probably comes back on again? My mechanic thinks I need a new converter. I do not want to have to replace the catalytic converter at this time, especially since the aftermarket cats do not last very long.
