Overview
The Dana Spicer 5-3147X is a forged, lubeable U-joint in the GM 3R series, with an inside snap ring and a 1.125in cup size. It is presented as an O.E.M. replacement within the GM 3R series, so the cup size and snap ring spacing are the measurements to check.
No vehicle or year is named for this joint. It is a universal fit by series joint, so the GM 3R yoke and the cup dimension decide whether it suits a driveline.
Key features
- Forged cross for the GM 3R series
- Lubeable design
- Inside snap ring retention
- Presented as an O.E.M. replacement
Choosing the right setup
Inside snap ring joints depend on the groove position inside the yoke ear, so the fit is decided before the cross ever moves. Look at the yoke ears from the inside face and confirm the grooves are clean and undamaged. A burred or bent groove can let the snap ring sit crooked, which holds the cup loosely and invites movement under load. Clean out old grease and debris before pressing in a new cross.
Lubeable crosses should be greased once assembled, and the grease fittings should be checked for flow before the shaft goes back on. Many drivers replace the cross together with the other joints in the same shaft so the set wears evenly. When removing an old joint, keep track of which cup came from which yoke so the shaft is returned in its original orientation.

Vehicle fitment
It is a universal fit joint for the GM 3R series, so the GM 3R yoke and the cup dimension decide whether it suits a driveline. Confirm fit for your vehicle’s year, model and trim before ordering.
Joints from other series are different parts and do not fall under the GM 3R designation. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the snap ring sits on the inside, confirm your yoke ears have matching grooves before pressing the joint in.
What’s included
The joint is a cross only. Check the package contents against your installation before starting.
