Unbalance in universal joint
When a universal joint spider is changed in any of the drives listed above, it is important that the components are reassembled so that the sub-components assume the same positions as before the universal joint was disassembled. Mark the universal joint before disassembly, as in the figure below, to ensure that the correct position is assumed on re-assembly.
If the components are not assembled as below, or if a new fork/center section from a different universal joint is installed, the result could be un-balance in the universal joint. Each complete universal joint is balanced at the factory. In the future, to ensure that customers do not have problems with unbalance, Volvo Penta will only sell loose spiders or complete universal joints as spare parts.
