I have an 02' Ram 1500 5.9L and it has 130,000 miles on it. im not sure what the previous owners had done to it as far as maintenence. What kinda major servicing do i need to do? i figured that i should probably change the tranny fluid and filter, anything else important to look at? thanks

 

check your rear end oil and check to see if your hoses have been replaced and spark plug wires

 

for the rear end oil, can I replace it with synthetic if it wasnt already? and should i do the same to the front diff. (it is a4x4) haha
