2013~2016 CX-5 Rear Diff and Transfer Case Fluid Change: Tools, Parts and Links

[madar]

I know the rear diff says level surface which I guess I could do by skipping the ramps, but for the front transfer case is there any issue with using front ramps only and filling to fill plug level? I don’t really feel like trying to roll up on both front and rear ramps by myself with no spotter, I can never really tell how it’s going and using 2 sets of ramps makes me weary.

I don't see how you can get a proper oil level like that, unless you rolled it back down to a level surface, crawled underneath and checked it, then put the plug back in.

Yeah I figured it out, I have a driveway that slopes pretty close to the ramp incline so rear tires in the garage ramps on the driveway slope, drive forward and front tires elevate to the level of the rear tires which remain in the garage, lots more room under the front too!

Looks like you have only one bottle of Mazda SG1 gear oil. And did you change the gear lube in the rear differential at the same time?

Yeah I had 2 bottles, did them both and still have 3/4 of a litre remaining

Great. Some trusted the capacity listed in owner’s manual and bought only one bottle of SG-1. It ended up they had to find an ride to got a second bottle at their local Mazda dealer for higher price.

Just a bump on doing this TSB if you have 13-16 AWD and cross in water or use underbody carwashes

Looks like an example here

CX-5 Rear differential whining

I see a lot of other people have the same issue at 50+ mph but my diff is a loud whirring/whining noise at around 10mph, is my diff shot or is it the viscous coupler, not sure and need my mazda experts here!!! Thank you!

Changed my rear diff fluid this morning. Last time was around 30k miles ago and in 2020.

Fluid was about halfway between new and dark. Only a very small amount of deposits on the magnet and no signs of other visible metals.

Instead of using a pump I just used some clear vinyl tubing I snaked through a hole in suspension arm and one of the Amsoil squeeze bottles to fill it up.

I forgot I had bought a whole bag of cheap crush washers years back.

Reminder to ensure your ‘13-‘16.5 has this retrofit vent for the rear differential on AWD models to avoid potential water intrusion into rear differential.

I would ask what the viscosity will tell you or what path of research you are headed down? Andnope, no one on the internet's most busy oil forum have not chimed in. https://www.bobistheoilguy.com/forums/threads/mazda-long-life-hypoid-gear-oil-sg1.291007/post-4784389 And I would caution of...

Not sure if everyone has read that TSB but the issue is

"The breather pipe grommet (A), located in the trunk, may be submerged in water that penetrated through the rear ABS wheel-speed sensor harness grommet (B) during a high pressure car wash. The water then enters the coupling unit (C) through the breather pipe (D). This creates rust inside the coupling unit, which causes internal wiring harness damage, setting the DTC and/or the coupling unit noise due to increased rotational resistance."
