What is a u joint and a yoke?
heres my best crack at explaning it for you:
u joint is a universal joint - its a 4 way union/connector with rotating caps on bearings on all 4 posts between rotating driveline components , typically one at the front of the driveshaft and one at the rear of the driveshaft.
The yoke is what the universal joint attaches to at both ends
flow chart front of vehicle to rear:
transmission>yoke>u joint>driveshaft>u joint>yoke>rear end
