Converting A D60 Pinion Yoke To U Bolt - The 1947 - Present Chevrolet & GMC Truck Message Board Network

OLDCHEV4X4 · 04-03-2008, 06:40 PM

My 1977 Chevy motor home has the strap style pinion yoke on the D60. It is loose after tightening the straps. So i got a new strap kit and its still loose. What do i need to do to convert it to the ubolt style. Anybody ever done this? Is there a kit with a new yoke? Can i just drill out the old one?
My motor home is not a 4x4, but D60 are common in 4x4's, so thats why i asked here.

I think you will have to change yokes. Here are a few links that I found on this issue of converting from straps to u-bolts.

This one looks like doesnt need new yoke if you have 29 spline yoke:

I'm pretty sure people have done it by milling a flat on the rear of the yoke around each hole, so the nuts can seat flush.

Yea, Thats what i was thinking. Remove the slinger, clamp it in the vice, and put 4 flats on the back.

Thanks for the links Yukon, I think im gonna buy just the bolts.

I know that some of those yokes are too thin to drill through and make the u-bolts fit.

Edit for clarity: It's where bolt used to thread in... makes the walls a bit thin to handle the torque, on some of them.
