How to Replace a Corvette Half-Shaft U-Joint - Page 3

For safety's sake, a new trunion was obtained from Zip Products, shown here prior to giving it a coat of Rust Oleum Satin Black.

Place a new u-joint with the bearing cups removed in the differential-side flange of the half shaft. Be careful when you remove the bearing cups, as they are lined with needle bearings which can fall out fairly easily.

Place a bearing cup on one of the u-joint splines and tap it down with a mallet, then flip it over and repeat the procedure on the other side.

You can use a 7/8 inch socket or the Zip tool to sink the bearing cup down just slightly below the groove that holds the snap retainer clip.

Use needle-nosed pliers to install a snap retainer clip over the bearing cup so that it seats in the groove of the flange.

Use a screwdriver and mallet to tap the snap retainer clip all the way into groove; this is very important, since this clip can and will spring out if it isn't solidly seated in the groove.
