Allo people, in the quest to solve my suspension issues i'm replacing my passenger side drive shaft amongst other things. The motor spares shop ordered what we believed to be the correct item, but it appears different from the original. The first obvious thing is the width of the abs toothed ring, which is only 5mm on the new item, but at least double that on the original. Now i've had the drivers side shaft replaced 18months ago, and this one has the narrow teeth also, and hasn't given me any problems, the abs works fine, it appears the sensor can pick up the teeth okay. But my question lies in the picture below of the original shaft which has what appears to be a weight half way along the shaft, which the new one doesn't have. Is this actually needed on the car, or are replacements coming without it??
Many Thanks!
Many Thanks!
