    Noisy Diff

    Have a slight rake on my van and now have noise from the diff when there is no load on it, i.e de-acceleration.
    Now thinking its because the diff is not horizontal the angle now at the rear is causing the gears to 'rub.' Or ring and pinion gear misaligned because of the rake?
    Was thinking of a shim in there to create a space but not to misalign any gearing.
    Has anyone had this issue before whilst having a rake on their van?

    I ran a fairly radical rake on my '65 Hella Sunshine, lowered in front, 1" lift block in back with 325/50 rear tires, and did not cause any problems with the rear end.

    First off, such a nice van that! Thats good to know cos my rake isn't as much as yours, a couple of mates have said the same so it may be worn gears or time for a replacement diff.

    before spending a bunch on parts, open up your diff and visually inspect to see if you can find any unusual wear.. either on the gear teeth faces, or even on the carrier. Could give you a clue as to what you need to replace.

    Unless you want to change gears and upgrade to a posi. Now would be an excellent time to do either or both
