I just got a prairie 400 4x4. It runs pretty good, when I was checking the fluids I noticed they were all low. What type I gear oil does the rear end take? Do you fill it till it runs out the plug? What kind of engine oil and front diff gear oil? Can you use car fluids? Where do you purchase parts for these? It needs a shifter handle and a tune up. I'm new to four wheelers but I'm a car mechanic so I'll be doing the work myself. Thanks for the help, Tyler.
