Product details
The EMPI 87-5870-0 is a low-profile end cap for 108mm O.D. Porsche 930-type C.V. joints that closes the open face of the joint and holds the grease in. It fits EMPI's 930 joints 87-9469-B, 87-9470-B, and 98-5094-B, plus the Lobro 98-5093-B that replaces Porsche 930 332 034 00. EMPI's drawing gives the cap a 109.75mm outside diameter. Sold individually.
A 930 joint is sealed on two sides. The boot and flange cover the shaft side, and this cap covers the face that bolts to the drive flange or stub axle, where the six joint bolts pass through it. A new or repacked joint should get a fresh cap. On the boot side, EMPI offers the short 86-2515-0 high-speed boot for prop shafts and taller off-road boots for long-travel axles. The 934 joint (128mm) uses its own cap, 87-5873, so match the cap to the joint size.

Common Questions
How many caps does a set of axles need?
One per joint. A pair of axles has four joints, so plan on four caps for a full rebuild.
Which bolts go through the cap?
EMPI's 930 C.V. bolt is 16-2413, a 3/8 inch-24 x 2 1/4 inch 12-point bolt sold in sets of six. Use a longer bolt if a grease flange or other spacer adds thickness under the head.
