    Are you getting any weird noises from the rear?

    The wear doesn't look all that off to me, from where i can see the wear pattern on the metal area itself, not the orange stuff.

    front and its not installed, just picked it up and wanted to check it. the inside edges have some funny wear, the pattern is on the inside the teeth, its not bad but I just wanted to check it before I toss it under the truck

    I didn't have any marking compound so I used some hightemp grease /forums/images/graemlins/tongue.gif

    I'm thinkin it could probably use a few less shims on the pinion, but in all reality, i wouldn't worry about it too much being in the front, if it were in the rear and used on a constant basis, i would have it reset.

    Really depends on what kind of off road driving you will be doing with it i guess. Major, heavy duty use, or just the casual mud or hill climb?

    Casual use, don't worry about it, heavy duty,extreme type stuff, reset it.

    I noticed it has a spool installed, thats why i was asking if this was in a front or rear.

    Hey Jeremiah,
    Alot of racers set gears up in this manner, with the pattern on the toe end of the gear tooth because thinking is gear pressure will spread towards the heel of the tooth. Backlash will move that pattern too, so if you don't have .008-.012-.015max backlash I suggest setting that then seeing what you have.
    I have gear compound, bearing puller and indicator so if you wanted to bring it with you next Sat. go right ahead and we can check it out.
    Remember two things that always crosses me up.
    1. read the pattern as if it is in contact with the pinion not as rotated out. As rotated out, it looks as if you need to add shim to move the head out, but reallity as the ring is in contact with pinion, you would need to remove shim to move the head of the pinion in. (seems confusing but think about and you'll get it).
    2. The front is driven off the coast side of the tooth. Still set up using the drive side but it gets confusing which side should I set up on.

    I'd run it if back lash is set ok.

    without putting the gauge on it I would say the backlash is VERY tight. I will toss the axle in the pickup when I come down /forums/images/graemlins/waytogo.gif

    I'm hoping to have the plow truck running by the 24th (it may not have seats by then). BUT, I hurt my back yesterday so I'm going not going to be out the next fews days working on it /forums/images/graemlins/dunno.gif Figures it was crappy and looked like it was going to rain for the last week or so, now its going to be sunny and in the 60's today, lower 70's tomorrow and upper 70's friday with sun and I'm stuck inside /forums/images/graemlins/rolleyes.gif /forums/images/graemlins/angryfire.gif
