OK guys I received my gears from Motive Gear part # C887391E. The pinion in this kit is "straight" with 10 splines. The pinion (1 3/4) I pulled out of my center section is "tapered" with 10 splines. Did I get the wrong ring and pinion?

thanks

 

Yes ! not interchangeable DO you have a 489 case ??

 

The only "489" case gears I could find on Motive's website had 29 splines? The 741/742 all are straight....

 

OK, guess I was wrong....Richmond sells a 1.875 10 spline tapered pinion and ring set. Im a jack ***!

 

No your not. You just visited the school of hard knocks.

 

I think any one who has has rebuilt a rear end has made a misunder stood buy or perchess. learning curves SUCK
