    My buddy's 14 bolt bearings are screwed. If we install new ones will we have to reset the backlash or not? Thanks for the help. /forums/images/graemlins/usaflag.gif /forums/images/graemlins/usaflag.gif /forums/images/graemlins/usaflag.gif

    Do a pattern check and check what the backlash is before you tear it apart.

    The answer to your question is no. All you have to do is mark properly where the adjusting screws (large with holes all around them) were before you start, and after replacing the bearings, move them back to their original position (exact number of turns). Then torque the bearing caps to spec and thats it.

    This article will help you: Detroit Locker Install It's very easy once youre doing it.

    Edit: I'm talking about the two bearings on the sides of the carrier only. If you need to replace the pinion bearings, then yes, you have to set everything from the beginning.

    <font color="green"> I think that it's a good idea to check the backlash when you replace the bearings. You never know what might happen, and it only takes a few minutes to check it. </font>

    Is that is what a dial indicator is for? Any trick to measuring it if you don't have a dial?

    The reason to check the backlash it so that you know what its at so when you put it back together you know where to run it.

    A dial indicator is almost worthless when dealing with a used set of gears. The factory specs. are of no use on used gears. If there is no side to side play in the carrier, you could measure it first, then set the same when you put it back. I always check pattern before disassembly and set backlash for the best pattern durring assembly.

    The backlash openes up a little bit when the gears get used. The backlash only changes the pattern verv minimal, the pinion depth is what changes the pattern.

    You would be amazed at how much backlash changes the pattern on a used set of gears.

    Well from my experioce it doesnt change the pattern very much, a few thou is nothing. I suppose it all depends on how much its changed.
