Rear differential oil change guide - Rear differential oil change guide

Today I changed diff oil and snapped a few pictures along the way. This is pretty easy to do and there's no reason to pay someone else to do it! This is only intended as a guide blah blah blah consult your owners manual you know the drill!

What you'll need-
Rags or paper towels
Gear oil, I buy 1 liter
Funnel with a flexible hose on the end
Drain pan
10mm Socket with 3" extension
17mm socket
Ratchet for the above sockets

First I like to drive around a few miles to warm up the oil. If this...

Thanks. As I questioned with the other differential, any %age of Lucas help? Could it hurt?

Just curious does it have to be hypoid gear oil? My local store and syn royal purple 85w-140. I have in my shop redline 75w-90. In my vehicles I always use syn gear oil with the additive for lockers that should be fine right? This is my first sxs just in case this is a ridiculous question.

I'm just going to use Lucas engine oil adder and some 90w for the diffs. Neighbor did this and the rear diff is a lot quieter. Also going to jack it up on one side so it can have a proper amount of oil on the rear diff.

I'm sure it will be fine. I was hoping someone smarter than me would chime in here. I don't really know enough about the different kinds of oils or additives to give you guys great advice on that subject. My gut says you'll be ok for whatever that's worth!

Amsoil Synthetic ATV/UTV Transmission & Differential Fluid

I use Amsoil in every thing I own. Prior to my 700-4 I used the engine oil and diff case fluids in both my 01 Foreman and 01 Rancher. My Duramax, Lexus and my toy hauler's generator are filled with it.

Can't beat it in MHO.

Good write up . Thanks. I'm using a mixture of 75-140 Syn and 25% Lucas in both. I warmed mine and poured a few oz's of just pure 75-140 thru to flush it. In the olden days in England when the chaffeurs did all the car maintance, they'd put in a flushing oil , drive 4-5 miles and change the oil again with their preferred oil. I don't go that far, but with all my 4 cycle engines: lawnmowers, tractor, truck, car, airplane, I usually put some clean oil thru after its all drained out, let it drain, then fill. I do that with oil in my P700 and the diff's. Just a thought.

How often do you change the diff oil

How often do you change the diff oil

I changed it at the initial break in service and then maybe once a year after that, which is probably overkill!

I just changed mine over the Amsoil synthetic and I think Honda employees must be smoking something. The underside protective cover was install backwards. The drain hole was on the opposite side from the drain valve. It's a mirror item but come on!!

The skid plate on my 700 was also backwards. Same as yours. I made a dam with towels to direct the fluid to over to the hole on the other side. Messy but worked.
