Since your differential/gear oil can go bad over time and needs to be replaced, you should be aware of the symptoms that indicate the oil needs to be changed. Stock I take it a torsen differential the TRD is a limited slip. What is the difference berween a limited slip rear end and a posi? Or are they one and the same? If they are different, were they both available in 1st gen birds? How do you tell the difference.
