I would like to change the front differential fluid on the 1997 S-10 4WD Blazer. Is this a difficult thing to do? Is there a drain plug? How do you drain the fluid? I see the fill plug in the manual.

Thanks.

 

when i changed mine i used a small hand pump (meant for putting oil in a differential) and pulled as much oil out as i could through the fill hole, then refilled with fresh oil. did the same with the rear. must have been low on oil, because afterwards i had a oil leak at the axleshaft seal on the left side. once that was took care of, its been fine for the last 10K miles. rear axle also had a oil leak so a couple of weeks ago i took the back cover off, did both axle seals and cleaned out the differential real good before refilling with oil. need to pull the drums off and see if i have any leakage, hopefully not, the axleshafts were scored up pretty good and i may end up swapping rear axle assy's with my parts blazer if im still oiling my brakes.
