Question: How often should I change the differential fluid?

I bout my 2006 Montero used with 67K miles on it. It now has 82,600 on it. It was cherry when I bought it, no kidding- never driven off road, no tears in leather seats (there are now). II am off road in muddy or dusty conditions about once a month for a couple of days. The rest is city driving, stop/go, wait. have added a K&N filter, OME 2" lift via struts/springs front and rear, heavy duty. I have added 285R75/17 ProComp Extreme A/T tires x 5 on stock rims. This suspension/tire setup is awesome, very stable with plenty of bite and clearance for the trails I'll be using. I hope to add ARB AirLockers front and rear within the next year. I've also scratched the rear bumper a bit, now have BlackHorse? bumper guard. Also want to add 2nd battery, on board air compressor, of course, for the lockers and a oad of other goodies, like lights, LED accents, rack w/tent, fire extinguisher, full medical kit (I'm an NP), fridge, good seat covers and a few other odds and ends. Should I just wait until I hit about 90,000 miles and do lockers and fluid change then?

I would say every 90k. Or if you go into deep water it should be changed.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
