I changed my rear diff today and was my first time doing this. I really didn't have the right tool's but I did it.


I push the car off the ramps and the diff dumped the rest of the oil $HIT!!!

this is where I knocked over the damn oil

 

haha...i hope you filled it when your car was on the ground.

 

Man I HATE ramps. I tried them twice and after my car went over the edge, I said never again. They are hard as hell to use my yourself and they don't look all that safe. Decided to buy a jack and jackstands and get it over with. Good investment. I'm not looking forward to doing this. Just got my car 2 weeks ago and it's at 27K miles, so I'll get to do this in the middle on winter Maybe I'll wait another month if there's a ton of snow.

 

well you got a nice mess there LOL

wondering if you have ever tried AMSOIL synthetics.


also dont forget to re-check the levels after you drive it for a couple miles

 

If your car is still on stock suspension, you can do the rear diff fluid change with the car on the ground. No need to use ramps, etc.

 

My car is lowered quite a bit (not slammed, but maybe 1" of space between fenders and tires) and I had no trouble getting under the rear diff.

 

sorry i know this is super newb question but i never had done rear diff fluid yet on any of my cars and i plan to do my evo's sometime in dec. is this known as transfer case fluid also, cause my friend told me that it is

 

it uses the same fluid as the transfer case but it is not the same thing. The transfercase is at the front of the car connected to the transmission.

 

i understand...well anyways like i said im changing my tranny fluid and my rear diff fluid too, should i change the transfer case then? lol thanks for putting up with my confusion. i have 33.5k miles on my car

 

Yes you should. An AWD transmission transfers power to a transfers case to get power to the rear wheels as well. A real diff is what will give power to the different wheels (so it's in the middle of the rear wheels). I don't know what an evo has but there's different types of differentials. Some clutch based and other are gear based. It's normally just gives different amount of torque to different wheels based on different driving conditions. Open diff = 1WD which is in most cards and limited slip = true 2WD.

 

also just to be sure, i am buying all my fluids from this online site an MT90. do i just buy a couple extra bottles of MT90 and pour a little more then half in rear diff and a little more then half in transfer case, basically?

 

love this site....learning more everyday

 

I wouldnt use MT90 in the T/C or Diff though, Id go with the stock diaqueen stuff, and amsoil for the tranny.

 

buy yourself some tools.

 

what other fluids are there?
Oil, transmission fluid, front diff, rear diff, transfer case, and?
I do oil and transmission fluid myself. How hard is it to change front diff, rear diff, and transfer case?
Getting so close to get home and I'm afraid to see my evo. Too much work to do.
Fluid change, full detail, parts install, rotation, alignment, etc......
