Hey guys recently did my diff oil in the front and i thought i would share with you guys how too.
Step 1
you need to get under your vehicle (either by stands, ramps, crawling under, or in my case on a lift we convinently have at the marina i work at!
Step 2
If you have a Z71 package you can remove the front skid plate, it will make it alot less messy and easier!
Step 3
Place a suitable drain container for approximately 3 quarts of gear oil
step4
Remove the lower plug it is removed with a 13mm wrench or socket, its a long thread bolt in the bottom of the pick and has a plastic sealing washer on it. Once removed, remove the upper fill bolt which is removed with a 18 mm socket or wrench.
Step 5
while oil is drainging i like to take a sample of oil to inspect and clean the metal shavings off magnetic bolt.
I noticed how dirty my oil was so i decided to flush my housing out with some fresh oil and letting that drain through (dont ask why im anal and i didnt like the color of oil!)
Step 6
After all oil is drained i then cleaned bottom drain plug surface inspected drain washer (mine was still good)
and reinstalled lower drain bolt after drain bolt is installed then you can get your gear oil of choice i used a hand pump that attached to the quart bottles to fill the the differential and filled it with 75w90 yamaha gear oil that we use in boats (its the same gear oil as used in cars if not better it has extra anti foaming agents and is more resitance to water breaking the oil down, its also much sitckier and designed to cling to bearings and gears better)
step 7
The differential will be full once the oil begins to flow out of the hole you are filling from. once oil is full clean o ring on top fill plug and make sure surface is clean and reinstall vent plug.
its a pretty easy thing to do that anyone can do
i hope this will help anyone that doesnt know
