Tripod joints are used at the inboard end of car driveshafts. The joints were developed by Michel Orain, of Glaenzer Spicer of [[Poissy]], [[France]]. This joint has a three-pointed yoke attached to the shaft, which has barrel-shaped roller bearings on the ends. These fit into a cup with three matching grooves, attached to the [[Differential (mechanics)|differential]]. Since there is only significant movement in one axis, this simple arrangement works well. These also allow an axial 'plunge' movement of the shaft, so that engine rocking and other effects do not preload the bearings. A typical Tripod joint has up to 50&nbsp;mm of plunge travel, and 26 degrees of angular articulation.<ref>[http://www.gkndriveline.com/drivelinecms/export/sites/driveline/downloads/brochures/driveshafts_english.pdf GKN Driveline Driveshafts] {{Webarchive|url=https://web.archive.org/web/20120723010219/http://www.gkndriveline.com/drivelinecms/export/sites/driveline/downloads/brochures/driveshafts_english.pdf |date=2012-07-23 }}, [http://www.gkndriveline.com gkndriveline.com] {{Webarchive|url=https://web.archive.org/web/20190703124825/http://www.gkndriveline.com/ |date=2019-07-03 }}.</ref> The tripod joint does not have as much angular range as many of the other joint types, but tends to be lower in cost and more efficient. Due to this it is typically used in rear-wheel drive vehicle configurations or on the inboard side of front-wheel drive vehicles where the required range of motion is lower.
