I have a 5 spd. 95 pathfinder SE v6. In first gear, I will begin to take off and start moving while I am releasing the clutch, and all of a sudden (from the rear end or rear middle) I hear and feel a pop. Don't notice it in any other gear, just when I take off from a dead stop. I do tow a boat and 4 wheeler quite frequently. It feels as if the lug nuts are loose and they are popping when I hit the gas (even though they are tight). It has been doing this for a long while. Also, when I turn, the drivers side rear wheel well has a squeeking rubber sound (sounds like a warped rubber disk, but only notice it when I turn). Not too familiar with these rear ends, is it a limited slip? As far as I know everything is still stock. I checked the rear end oil level, and it is full (the oil is dark blueish in color, but not burnt). If anyone has experienced anything like this and could help me out in pin pointing the problem, I would greatly appreciate it.
