1 dust cap was missing from the original delivery. Revine sent a replacement with 2 days delivery and it was the version with bearings instead of bushings. I removed the dust cap from it to complete the jack kit. The wheel and tire seem fine, but after installation I noticed the Zerk was a bit loose so I tried tightening it before greasing. it turned out that he did not speak up, but was ripped off. Classic Chinese quality, I saved a dollar but will only have 1/10 of what a more expensive product would have.
