    I am checking on this for a friend, he just installed one and he feels that there is to much slack in it. How much is normal.

    service manual states 10deg or more at the ring gear
    multiply that by the gear ratio and that is what the pinion will look like /forums/images/graemlins/shocked.gif

    you could tell him it is trashed and offer to trade him your open dif to 'help him out of that jam'

    I could try that but I think our friendship would end in an ugly way, bodyparts(like my arms and legs) and drivetrain parts all over the garage floor in a big ugly mess. Also he is the one that helps me install all my junk so I better behave. /forums/images/graemlins/grin.gif

    There was a big discussion on this some time ago, and the concensus was 1/8 to 1/4 turn was normal.

    agreed, mine turns back/forth quite a bit before stopping when i have a tire in the air and am taking the lug nuts off. Thought it was a lil wierd at first... but I guess its normal. /forums/images/graemlins/smile.gif

    If you'd like an entirely-too-detailed explanation of why it works that way, click on the link in my sig, then click on the "Technical" link at the left of the page. /forums/images/graemlins/thumb.gif

    I had grabbed that off the net 4 or 5 years ago, as it gives the best explantions of how various automatic lockers work that I've ever read. I'm glad I grabbed a copy when I did, as I've never seen it again since the authors web site went away. /forums/images/graemlins/shocked.gif I figured that a guy with that many patents on lockers probably knew what he was talking about! /forums/images/graemlins/thumb.gif

    I just had this discussion on another board about 2 months ago cuz I noticed I had a ton of slack in my rear driveline. It turns out that 1/3 of a rotation in my burb would be expected with 4.10's and a ff14b rear w/detroit.

    Seems crazy, doesn't it?

    Nope, not off the top of my head, but I'd bet a safe guess would be...uh...YOU? /forums/images/graemlins/grin.gif /forums/images/graemlins/thumb.gif

    I just installed mine tonight. Then I drove it home 30 miles. I knew there would be some, but I wasn't expecting so much. I get a much harder bang when shifting to drive or reverse. There is definately more lag time from coast to power, etc. It was however, quieter and smoother than I expected. /forums/images/graemlins/truck.gif

    I have a Lock-Right in my DD. There's quite a bit of slop in it, so I'd assume a quick-loc would be the same way.

    Every time I step on the clutch, I hear a clunk of it unlocking, and when I release it again, I hear a click of it locking back up. I can't even hardly hear it anymore I'm so used to it, but its definitely there.
