    Gear question

    Going back to AZ Diff to have my gear oil changed on Saturday. I have noticed over the last month or so that the rear-end has started to whine on deceleration. Will changing the gear oil help this or will they need to make an adjustment to it?

    Also, they plan on using their own oil. Is there a better brand I can take with me as far as synthetic or just stay with theirs?

    Thanks!

    Thanks guys I will hit up Checker tomorrow. I will see what they say about the whine on Saturday. I may be replacing the 3.73's with 4.10's in the near future anyway.
