Hey all, I have a few questions concerning my 06 Rubicon's differentials. I just pulled off the front diff cover so I can start to replace the outer axle shaft seal(its leaking) and I noticed that the gear oil didn't look quite right. It is a greyish color. Is that normal? Here are some pics of the oil and front diff.
While I was moving the tires to watch it spin inside, I decided to see what gears I have in there.(I bought it from a dealership who didn't know) and I am supposing that I have the 4.10's. I spin the tire around once, but the front driveshaft only spins around twice. Is that right for 4.10's? I thought it was supposed to go around jut over 4 times. Please correct me if I am wrong. One last thing, I engaged the front locker and rotated the tires. The locker locks but when I turn one of the tires, it spins for a short time then the other one clunks in. Is it normal for there to be a lag there? And is it supposed to clunk at all? I apologize for all of the questions. I am also thinking of re-gearing since I have the front torn open. Any preference on the brand of gears I should look into? Im leaning towards 4.88's. Thanks for all of the help.
EDIT: I am running 33's
