How often should a 4 wheel drive fluid flush be done on a rear differential?
Generally every 30000 miles unless you have synthetic fluid, and the transfer case as well.

First, check with any and all car manufacturers. You may be surprised that "flushing" is not recommended; or if it is, it will be at around 150,000 miles. And the so-called f…lushing has many detractors, many who say there is a good chance of engine destruction because of the flushing process. Consider that as long as the tran fluid is clear and pink, it doesn't need anything done to it. Flushing, in general, is asking for big time trouble.

Answer . Valvoline recomends 15,000-30,000 depending on how hard the vehicle is used...I do mine about every 30,000
Wheel alaignment frequency . If you are noticing any uneven wear on outer edges or center of tread even though you have been diligent in keeping air pressures correct and …have not hit a curb with any force or found a mega pothole. Also good idea before purchasing any new set of tires
Answer . Be more specific, Are you talking about the transfer case, transmission, or front differential?
What is the preload on the pinion bearing and the backlash on the crownwheel and pinion inside the rear differential of a 1997 ford explorer 4 wheel drive?
Preload for pinion bearing . The shim between the inner bearing and the pinion is critical and ifit's lost you need special tools to set the pinion depth. replace thebearin…gs and seal with an new crush sleeve thighten the pinion nutuntil the sleeve crushes and you can't move the pinion up and down.Then very slowly tighten the pinion nut checking the rotational torque.You will need an inch pound torque wrench, when the preload is correctit should take between 20-25 inch pounds of torque to rotate thepinion. If you get it too tight you need to replace the crush sleeveand start over. Proper bearing preload and gear mesh are critical.
When I did this at firestone the most common intervals were 30,60,90k, etc... Answer Your best best is to check out your owner manual for any type of service schedule, but …if you can't find it go to driverside.com and enter in your make/model/year. They have a service schedule that's pretty good, and you can also record what you do so you have a good history report for when you want to sell your car down the road.
At 18000 miles if towing
Alignments the manufacture suggests every 6 months. I work at a place that does alignments and I only do them if I see irregular tire wear (might be too late at this point), o…r if the truck pulls, but the alignment could be out and the vehicle goes straight down the road. So there is no Good answer. I would at least get an alignment done when new tires are installed and/or new front end parts are done. Hope this helps.
When refering to "service" I assume you mean fluid change and/or check. I check my fluid every oil change and change my fluid twice a year. Granted i use mine very hard offroa…d. I also prefer running synthetic fluid, but check with a dealership and make sure yours doesn't take a special lubricant.
Only off a cliff; if your differential siezes your rear end falls off a millisecond later.
once every 30 days, to keep seals and moving parts lubed

The differential is part of the transmission gear train. It does not have a separate motor.
Nissan Maintenance recommends every 60,000 miles or every 48 months.
In American Cars
The differential is the 3rd member of the power train: 1) Engine 2) Transmission 3) Rear end/ differential If you look under the rear (of a rear wheel drive) vehicle you wil…l see a large ball with tubes extending to the wheels. Looks like and refered to as the "bango" that is the differential. Inside are the gears and bearings that control the actions of transferring power from the transmission and driveshaft to the wheels

A few things to consider: . Each maker has a recommended service interval . Trucks that go through creeks and such may contaminate the fluid, it should be checked for contam…ination and changed as needed after each use. . Trucks that see sever duty, Off road, towing etc should be serviced much more often that recommended by the maker.
There is no concrete answer. Different vehicles have differentneeds. For instance, an off-road vehicle may need a differentialfluid change as often as every 30,000 miles. A ve…hicle used foreveryday travel may never need a differential fluid change. Somemanufactures consider the differential lubed for life and othersrecommend that it be changed at a set mileage like 100,000 miles.Refer to your owner's manual for when or if yours should bechanged.
