## Questions & Answers

**Q: Could this be used on the driver side differential on a 2010 f150?**
A: Thank you for the question.  National catalogs 710950 for the axle shaft seal, 4WD; Viton Type ; with 8.8 (in) Ring Gear ; Independent Front Suspension.

**Q: Is this for a automatic transmission**
A: This is just a seal it could be used for many applications you will need to look it up to verify fitment for your particular use, My application was as a rear tail shaft seal of the drive shaft yoke to the spline of the output shaft on an automatic transmission on a 2007 Ford E150 van with a 4R75E 4 speed Automatic in it. Hope this helps
