Nissan 39241-8J126 Repair Kit-Dust Boot,Outer

When the time comes to overhaul CV joints, start by thinking of other alternatives before you can proceed, as complete rebuilt driveaxles are available on an exchange basis and this will facilitate the process. This is because some auto parts stores sell boots, which can be installed without taking out the driveaxle from the vehicle; nevertheless, removing the driveaxle and disassembling of the CV joint is better since one ensures that any contaminants like moisture or dirt that could cause wear are absent. First remove driveaxle from vehicle and clamp it in a vise cushioning vise jaws with wood or rags to protect driveaxle. To begin with for inner cv joint open boot clamps by prying loose their locking tabs then remove them and discard them. Slide boot back onto axleshaft; next take wire ring ball retainer out of outer race to remove outer race from inner bearing assembly. Wipe off excess grease from the inner bearing then remove snap-ring at axleshaft end and slide off inner bearing assembly tapping it off if necessary with hammer and brass punch against inner race. First mark inner race/cage for correct reassembly orientation - shows how to do this. One can pop balls out with a screwdriver or piece of wood without damaging the inner race, balls or cage. Rotate inner race 90 degrees so that it aligns cage windows with its lands then rotate it out of cage. The inspection involves cleaning components in solvent to remove all grease residues and checking cage/races for wear, damage, pitting, score marks or cracks where shiny polished spots are normal/harmless. Insert inner race into cage making sure matchmarks align then press balls into cage windows during reassembly. Next use tape to protect axleshaft splines while sliding small boot clamp and boot onto axleshaft, removing tape afterwards. Once this is done position inner race/cage assembly on axleshaft with larger diameter side of cage facing axleshaft end. Proceed to install a snap-ring and then fill boot with CV joint grease before packing grease manually into inner race/cage assembly. Slide outer race onto inner race; install wire ring retainer. After wiping away excess grease from axle boot groove on outer race, seat small boot diameter in recessed area on axleshaft and fasten this clamp. Adjust CV joint to the correct length equalize boot pressure with a screwdriver, and do not damage boot when installing the clamps. Put back driveaxle assembly. For outer cv joint remove boot clamps then followed by driveaxle itself.

The suspension and steering components need to be checked from time to time. Abnormal tire wear or excess worn suspension and steering linkage components generally lead to poor ride quality, excessive and abnormal tire wear, reduced fuel economy and poor vehicle handling. Check the shock absorbers by parking the car on a flat surface, turning off the engine, putting on the brake. Push it down at one corner of the vehicle then release, noting how far it bounces up and down. It should stop moving after one or two bounces and come to rest levelly in a flat position. If it continues movements up-and-down or fails to return to its resting position, then a worn out or weak shock absorber may be involved. Repeat this test on all the remaining three corners of the vehicle. Raise and hold the car with jack stands for evidence of leakage from the shock absorbers. Also check that they are well fixed plus in good condition. It is also important that you visually inspect all your steering and suspension parts for any damage such as leaks, distortion seals boots and bushings. Examine control arm bushings where they attach to chassis, look over tie rod ends and ball joints, inspect steering gear boots for cracks or fluid leakage. Clean the bottom part of the knuckle joint while an assistant turns the wheel inwards against it; this is done as a test for movement at this joint which is between these two suspensions parts if any movement is detected as such then either one will have failed hence must be replaced. Hold each front wheel at both front edges like gripping a steering wheel, and push in front and pull backwards, then feel any looseness in steering system parts. In case play occurs in those linkages, the idler arm and outer tie rod ends should be inspected before examining anything else concerning them. Check CV boots for tears, cuts, loose clamps since they prevent dirt, water, and foreign materials from destroying constant velocity (CV) joints. If lubricating oil is leaking or broken, replace boots.
