I have to change out my carrier bearing and I'm wondering if anyone knows if this spicer carrier bearing (part #210391-7X) is better than stock DC. I'm also wondering about these spicer part # 5-188X U-Joints. Are these better than the stock DC replacement parts. Any other suggestions, or comments would be much appreciated. I need to change these out soon. I would like the best parts available if they are not too outrageous in price.
