I need to replace the short yoke in the driveline on my '05 SX-M 1.66. The yoke I have now has GKN stamped into it. I the genuine volvo parts section if I want GKN I have to buy the entire driveline assembly. However I can buy jusy the yoke in the Rockwell setup. Can I replace the GKN yoke with a Rockwell yoke? In the aftermarket section it only lists one yolk that crosses to the Rockwell number. Below are the parts breakdowns for the Rockwell and the GKN.

Re: Rockwell and GKN Yokes Interchangeable?

In an effort to try and finalize this thread for future references, I can only speak of what Mercruiser did back in 2004. I'm not sure if Volvo followed suit or not, But maybe with the description between the two manufacturers below will help with this type of question.

The rockwell assembly is gray in color where the GKN assembly is black in color.

The rockwell assembly has the cross and bearing end caps retained with the clips at the bottom of the cap, inside of the yoke ear.

The GKN assembly has the cross and bearing end caps retained with the clips above the cap on the outside of the yoke ear for standered Bravo and Alpha.

The Rockwell U-joint assembly was a greasable assembly. The GKN is a permalube style, like the alpha U-joint assembly and cannot be greased.

The GKN Bravo X assembly is black in color and has the cross and bearing end caps retained with clips at the bottom of the cap, inside of the yoke ear, as did the Rockwell style (Bachman U-Joint assembly).

Also the GKN uses a special set of tools from Mercruiser part number 91-866107A01 (GKN U-joint tool set).
