Changing Rear End Fluid ?!~??~!?
I was wondering how difficult it is to change the rear end fluid on my new 3.90's. ????
I have 500 miles on them and it needs to be changed.
My old man does own a lift and most tools. Im a 26 year old newbie who would like to get his hands dirty....
Thanks

Can you loosen and tighten two bolts?
If so you can do this job, get underneath the pump remove the drain and fill plug, let it drain, tighten the bottom plug. Using a pum, pump the fluid and Gm addittive to the diff. Fill till it comes out the hole, quickly put bolt in and tighten.

Hi UpToVT - 
I agree with stangkiller18 - this job is just that easy.
You need the pump - I bought mine at AutoZone for $8 I think.
that pump will come in handy when you do the trans (if it is a manual).
best regards -

Not trying to be a smartazz but I just read this in the tech section as I plan to do it myself. Great step by step!

Did mine last week, pretty straight forward. Put the Redline 75W90 back in. (already has additive) Took about 1.8 quarts. Make sure car is level. The jack and stands tend to get in the way somewhat.
