Rear Diff - Detroit Play

[GrillMaster]

Have 1/4 turn of play in my pinion with a stock car/NASCAR detroit locker, new bearings and stock gears.

Thinking I need to tear it down to inspect it. Thoughts?

My dad has a grizzly locker in his. When it was new it had the same.

Just checked it again. It's only got 1/8 turn of play. Is this ok?

no problem. Half turn of the yoke on a Detroit is about right. With the clearance of the ratcheting teeth, multiplied by the gear ratio, with a sprinkling of added play with the backlash and axle shaft spline clearance. That is what you get.

Normal same on my soft locker.

Yeah like others said, normal. Just wait til you take off from a stop light after a turn and the teeth re-engage on accel.;D

I've only heard it pop super loud a few times. The ratchet sound is pretty noticable. It's fun scaring ppl in the Trader Joe's parking lot haha

added a poll, post your results

Where is the half turn of slop?

Where is the half turn of slop?

in the driveline. Comes mostly from the gears in the detroit I believe.

I ment in the poll.
I know where it is in the driveline and consider it completely normal for a low gear set and a detroit.
