叉车万向传动装置主要用在两轴线不重合，且在叉车运行中，不断改变相对位置的轴之间的动力传递。用在负荷较大的叉车上，变速器与驱动桥之间的连接，以及叉车发动机与油泵之间的连接等。叉车万向传动装置是由万向节叉、十字轴总成等所组成,其作用是将变速器动力传递至主减速器。传动轴传递扭矩大，速度高，工作繁重。因此，虽然其结构并不复杂，但技术要求却很高。否则会出现抖震、发响，脱落和断轴现象。
叉车万向传动装置应该不紧不旷，螺栓齐全紧固，装配角度正确，润滑良好，行驶中不抖动，无异响。因此在叉车使用中，应认真做好传动轴的养护，发现问题必须及时处理。
叉车行驶中，传动轴要承受很大的扭矩和冲击载荷，同时作高速转动，伴随不断的振动，其润滑条件较差，因此容易产生磨损、变形和损坏，从而工作失常，还会出现异响和抖震等故障。叉车起步时，若车身发抖，伴有“格啦。格啦”的撞击声；行驶中还能听到底盘有一种周期性的响声，速度越快，声音越大。严重时，驾驶室振动，握住转向盘，手有麻木感。
其原因有：万向节十字轴及滚针磨损松旷或滚针断碎；各连接部分的固定螺丝松动。传动轴弯曲变形等。遇到上述故障时，可到车底查看各连接螺丝有无松动，并用手晃动传动轴，即可检测出磨损部位；将后轮架起、挂档转动，可观查传动轴震动及异响情况；也可就车用千分表检测传动轴变形量，查明原因之后，分别予以修复。
传动轴总成动平衡状态一旦破坏，会在工作中受离心力造成的附加动载荷作用，易产生弯曲变形，引起传动轴振动噪声，增大动载荷，传动效率下降，加速零件的损坏。使用中传动轴意外撞击，拆装时敲击变形，堆焊后零件的相互位置精度破坏等等，均将使传动轴总成的旋转质量中心偏离旋转轴线，破坏其平衡性能。
养护时，要对十字轴承加注润滑脂；检查十字轴承有无松旷时、将变速器挂空档，松开驻车制动器，双手紧握传动轴轴管，左右用力急剧转动，不应有明显的松旷量，必要时拆下分解修复。传动轴养护时还要检查紧固件是否固定牢靠，传动轴外表和弯曲度，必要时修复。
传动轴维修装配前，须将其各部件清洗干净，尤其是十字轴的油道、轴颈和滚针轴承等处，宜以洁净的煤油洗净并用压缩空气吹干。配合面上涂以润滑脂，对合标记后装复。万向节装复后，应转动灵活并无明显间隙，也不能有发卡现象。
叉车变速箱与驱动桥之间采用传动轴联接。该型叉车传动轴由突缘叉、万向节、十字轴及轴承等组成，十字轴上装有润滑油杯，可由此注入润滑油，润滑各轴承。当十字轴在滚针轴承中产生过大的间隙时，应拆开传动抽，根据磨损情况更换十字轴或滚针轴承(必须成对更换)。轴承润滑应选用锂基润滑脂。绝对禁止用较稠润滑脂(如钙基润滑脂)润滑，因为使用稠质油会加速轴承或十字轴的磨损。
