Husband is very satisfied

My husband bought this for his Ford F150. He really wanted to use the Motorcraft brand but couldn't find it at a reasonable cost. This was the only one that he could find that was for hypoid limited slip differentials that wasn't motorcraft. He said it was very easy to use! Would recommend!

It's hard to find the correct weight for Toyota transfer case and rear diff. I'm glad I found this.
