2nd Gen Non-Engine/Transmission rears

How often does everyone out there change their front and rears fluid. Most have told me not to worry about it unless it leaks. And if so, what fluid should i use.

Every 50,000 miles. I use the mopar recommended stuff 85-140 synthetic I believe is what it is.

Definitely change the rear and 50,000 miles is a good interval. I would change it more often if you do a lot of towing. The rear end has a lot of valuable moving parts that require lubrication and like all lubricants, they need to be changed.



I used the stuff from the Dodge dealer (Boy, are they proud of their stuff).



I don't change the front as often as the rear because I don't use my 4WD that much.

Every 20,000 miles. The first 2 times I used Valvoline Dura-Blend 80w-90 & I am currently running Royal Purple 75W-140 gear oil.



I like the RP, the truck seems to take off better.
