The first step is to remove the single large boot clamp that maintains the inner tripod joint sealing boot inside the tripod joint housing, then throw it away and finally remove the small clamp that keeps the boot attached to the interconnecting shaft. Take the sealing boot off the tripod housing and lower it down the interconnecting shaft while caring that the bearings do not come loose from the spider trunions. Following this, undo the snap ring located on the spider assembly connection to the interconnecting shaft, ensuring you do not hit the outer tripod bearings. You may need to tap the spider assembly with a brass drift if it will not come off the interconnecting shaft on its own. Look at the spider assembly, tripod joint housing and interconnecting shaft for excessive damage. Any parts with obvious wear should cause the
Drive Shaft assembly to be replaced, because there is no way to repair those components. To install, slide the inner tripod joint seal boot retaining clamp onto the shaft, follow with the replacement inner tripod joint boot, making sure the raised bump in the boot is positioned in the shaft's groove. Attach the spider assembly to the interconnecting shaft, making certain it is set back enough so that you can use a brass drift to put on the retaining snap ring. Put the snap ring into the groove at the end of the shaft and push it into place until it clicks. Take half the grease from the seal boot package and place it in the tripod housing and grease the rest into the sealing boot. Line up the tripod housing with the spider assembly and slider it onto the assembly and shaft that joins them. Clamp the tripod joint seal boot evenly on the sealing boot and then use Special Tool C-4975-A to clamp the sealing boot on the interconnecting shaft, so that the seal is not dented or stretched. Use a trim stick to vent the inner tripod opening slowly so as not to damage the sealing boot and always place the stick flat against the tripod housing. Set the shaft funcionnale on the tripod support, remove the part labeled "Trim Stick," and fit the trilobal boot with the tripod base by placing the lobes in the dents in the joint. The final step is to clamp the tripod joint sealing boot to the tripod joint, using one of these procedures: crimp type (C-4975-A Special Tool) for crimp models or latching type (Snap-On YA3050) for designs with latches.
