2-piece driveshaft question
I've got a 97 sc with a 2 part driveshaft. the bearing in the middle is mounted in rubber. the bearing itself doesn't seem to have any wear or slop that I can tell. the rubber bushing around it seems to have just a slight bit of play. if you grab it and shake hard you can barely see the play, also feel it. it's not causing any issues that I can tell. don't feel anything unusual when I'm driving it. is this normal? truck has 87k on it. thinking about taking it on a trip of about 10k and don't need any problems. thanks for any insight.

Since the bearing is mounted in kind of soft rubber it will have some amount of movement when you try to wiggle it around a bit. This is normal. Shouldn't give you any problems on your trip. From what I've heard/read/experienced, they rarely go bad unless it's a really bad off brand of bearing in there. First time I replaced the carrier bearing in one of mine was around 150k, when I was trying to eliminate sources of vibration. The bearing was still good but it was cheap enough to replace I thought I might as well. Turned out to be a problem with a u-joint. I wouldn't worry too much about it for a while. Just check it every 10k or so. I hope you have a good trip.

thanks for the reply rangerman. I was kind of leaning towards what you thought but I wasn't for sure since I've never checked another one. I know in some applications, for example, motor mounts or radius arm bushings that the rubber is sort of attached or bound to the metal and you don't want any movement. I didn't know if thats the case with the carrier bearing bushing or if slight movement is allowed. I guess as long as it's not setting up a vibration in the driveline it shouldn't cause any problems. just don't want any problems as I'm going to some fairly remote areas. I appreciate your imput.
