Review on 🏆 Spicer SPL55-4X U-Joint Kit: Superior Quality for Uncompromised Performance by Aries Boyce

The U-joints were ok and the delivery was on time. My only issue is the included Zerk fitting. It's pretty low quality steel, I had to order a replacement U-joint because 1st somehow felt it was the wrong thread pattern, the fitting broke when I tightened it. I couldn't extract it with an extractor because the material literally turned into a soft metal like brass. I ordered the 2nd and scored through my own fault, but the same thing happened with the 2nd, even when I installed it before mounting it on the axle. I got it out with a puller. But I have the uneasy feeling that metal shavings have gotten into the bearings. The threads definitely don't match and due to the poor quality of the Zerk fit it will just snap if you don't leave it with 2 or 3 threads. Went to the store to get a new fit and hope it works.
