I went to my local O'reillys today to get gear oil and RVT so i could inspect my rear end, found out that my differentials require synthetic gear oil. i have been using regular gear oil. Could that be the reason why it is humming? im assuming thats why im finding small metal shavings on the fill plug.
Yeah i am going to swap the fluid. I was surprised that it requires synthetic fluid. The recommended Royal Purple is 75w 140 gear oil and its $20 a quart and i need 5.5 pints. Thats hurtin my wallet haha
Yeah no ****. Its all my local Oreillys has. I think ive isolated the problem though. Im assuming its my pinion bearings that are wearing out due to lack of gear oil. so i guess i get to learn how to fix that.
