Getting a gear install next week and want to be sure it's done right. It was reccommended to me that I get a carrier bearing to go along with my axle bearings and pinion bearings. I got one at advance and was wondering if it was the right one. I'm confused and the guy behind the counter wasn't exactly sure what I meant. He gave me what was normally called a carrier bearing, saying it had somehting to do with the back of the driveshaft or something. It's a Federal-Mogul bearing, and says A-5 on the box. Just wondering if this is what I need or if I need to go back. Thanks.
