### ⭐⭐ 2.0 out of 5 stars







  
  
    Does not fit 2009 F150
  

*by W***N on Reviewed in the United States on October 15, 2023*

Amazon indicates this fits the Ford 8.8 on my 2009 F150 XLT. Outer bearing, seal and pinion nut fits but the inner bearing did not. The race should have 3.54" o.d. but it's only 3.25". Didn't realize that until after I removed it. Can't say how well they work yet since the diff is apart and I have to source the inner bearing elsewhere.
