How much time am I looking at? 30 mins? 1 hour?

 

30 minutes if you have an air impact gun. Make sure you get the fill hole plug off before you get the drain hole plug off. That way if by some strange reason you can not get the fill hole plug off, you will have not just drained your differential.

 

Yea, deff dont have an impact gun. Thanks for the tip tho.

 

Very easy, I flushed mine so it took like 45 minutes. What i did was empty out the fluid, put a conventional 5 dollar gear fluid in there, drove it around to get whatever crap was there then filled it with my redline fluid. Just be sure you do the double wrench method when doing it, I had an impact gun but the knuckle on it wouldn't work right to take it off so i had to use a wrench. And its full when its about flush with the fill hole.

What is this double wrench method you speak of?

 

Get two combination wrenches - one the size of the bolt and one a step bigger. Put the box end on the bolt and hook the bigger one into the open end of the one on the bolt. You can apply more pressure and break the bolt free this way.

 

Yep, if you need a pic, i'll snap one of the double wrench method. I'm waiting for my jb weld to settle so i have time.

I kinda see it, and I think I know what you mean, but not sure. A pic would help.

 

Or use a breaker bar with the proper socket (24mm iirc). I'd advise against the use of an impact, just ebcasue you're dealing with aluminum here. Anyway it really shouldnt be really tight, and keep that in mind when you torque the bolts back on.

 

The reason I suggested an impact is in practice when you go to change the fluid on these cars it is usually the first time ever it has been changed. Those fill and drain hole plugs are frozen solid. I cranked and cranked on one with a regular breaker bar and I could never get it off. If you are careful an impact should have no ill effects and save you wasting an hour trying to get the dumb things loose.

 

Hopefully there isnt 16 year old fluid in the diff, I would cry.

 

Sorry man my battery is dead on my digi cam, i'll get you a pic tommorow hopefully. And if you don't do the double wrench method, get your ratchet, put the pole from your jack and viola theres your breaker bar.

 

we call it a cheater bar. just take another wrench and put the boxed end at the end of the wrench,ratchet youre using and push at the end of the wrench,(hence the name) cheater bar.

 

Its cool man, Im pretty sure I know what you are talking about.

 

so how much fluid does it take to fill it up? Also is redline mt90 ok for this job as I still have one quart left of this stuff. I guess I could search but hey since we are on the subject

 

FSM says 1.5qt, Ill be using Redlie super lightweight shockproof 75w90.

 

It should be somewhat flush with the hole you fill the fluid into. Redline MT90 is really meant for the trans, i have heard of it being used but your better off using the redline 75 90 NS which is meant for clutch pack limited slip differentials, or it might be the normal 75 90, it says on the back, i think its 1.6 qts to refill iirc.

 

ok thanks for the info guys! Off to order some of that stuff. THanks again!

 

I'm not sure if shockproof is for viscous only but it might be so choose according to your diff.

-Andrew

 

Well, if I read Redline's website correctly, they make an LSD version of it. We'll see what happens.

 

Yeah, i know that but i was just wondering if its like the 75-90 ns thats meant for clutch type lsd's, mebbe the shockproof is for viscous? I dunno, heh.

HAHA if its never been changed like mine was ..... you may be waiting a while for it come out.... my gear lube had the consistancy of .... basically wet concrete, including pebble sized globs. I sat there for half and hour with an air nozzle and my air compressor blasting trying to get all the crap out.

 

^how many miles? guess im changing mine next weekend lol
