I happen to be working on a 2005 jeep wrangler rubicon. The front cv is getting sloppy and is audible. Went to napa and asked for spicer replacement u joints and ball. They said that they no longer carry spicer and I wound up with their napa brand Proformer. I have never heard of them before and when looking at the box it said made in china. I found this to be rather shocking! Im now thinking of returning them and finding spicer parts. My question is has anyone used this brand before? are they any good? Thanks for your time and any information will be greatly appreciated.
