As long as you get your pinion nut tight and use a proper driver to install it, it should be good. Make sure your seal surface is in good shape also so you don't have premature failure. Review: Fit 1985 F250 with 10.25" Rear Axle - I had my 1985 Ford F250 start leaking at the rear differential. This seal fit perfectly in the Ford 10.25, replacing the old seal. I have had no issues with leaks since then. ## Features - 1 Year Warranty - Precision Fitting - High Quality Seals ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0078UAG0Y | | Brand | Yukon Gear & Axle | | Brand Name | Yukon Gear & Axle | | Customer Reviews | 4.5 out of 5 stars 64 Reviews | | Global Trade Identification Number | 00883584300694 | | Item Dimensions | 25 x 25 x 25 Millimeters | | Item Weight | 0.15 Pounds | | Item dimensions L x W x H | 25 x 25 x 25 Millimeters | | Manufacturer | Yukon Gear | | Model Number | YMS4278 | | Number of Items | 1 | | Part Number | YMS4278 | | UPC | 883584300694 | ## Product Details - **Brand:** Yukon Gear & Axle - **Item Weight:** 2.4 ounces - **Item dimensions L x W x H:** 1 x 1 x 1 inches - **Material:** Plastic - **Outside Diameter:** 10.25 inches ## Images ![Yukon (YMS4278) Pinion Seal for Ford 10.25" Differential - Image 1](https://m.media-amazon.com/images/I/61mS7PRKWaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seals up well. *by C***N on 15 October 2021* It's a seal.
