Nissan 39241-5V125 Repair Kt Dust Boot, Outer

Complete rebuilt drive axles are available on an exchange basis, which eliminates much time and work. Remove the drive axle. For the inner CV joint disassembly, remove both CV Boot clamps and discard them. Slide the boot down the shaft and out of the way by prying up the retaining tabs on the boot clamps. Mark the relationship of the inner joint housing to the shaft, mount the drive axle shaft in a vise with padded jaws, then tap the inner joint housing to dislodge the cover on the end of the joint. Remove the snap-ring from the end of the shaft, then mark the relationship of the shaft and spider for reassembly. Using a hammer and a brass punch, drive the spider assembly off the shaft. Slide the housing and boot off the axle shaft. Clean the components with solvent to remove grease. Inspect for pitting, score marks, cracks, and wear. Shiny spots are normal. Check the splines on the shaft and spider for wear. If any undesirable conditions exist, replace the entire joint or drive axle assembly.For reassembly, wrap the axleshaft splines with tape to avoid damaging the boot. Slide the small boot clamp and boot onto the axleshaft, then remove the tape. Slide the large boot clamp over the boot. Slide the housing onto the shaft. Install the spider assembly, aligning the marks. Install a new snap-ring. Lubricate the spider assembly and housing with CV joint grease. Move the housing up onto the spider, aligning the marks. Apply a bead of RTV sealant to a new cover, then tap the cover into place. Fill the housing with approximately 3-1/2 ounces (100of CV joint grease. Adjust the CV joint to the desired length. Equalize the pressure in the boot and install the boot clamps.For the outer CV joint disassembly, on specific models, the outer boot may either be rubber or plastic. On models with a plastic boot, replace the entire drive axle assembly if damaged. On other models, remove the boot clamps and separate the boot from the outer CV joint. Clamp the axleshaft in a bench vise and drive off the outer CV joint with a brass hammer. Remove the retainer ring for the inner race and slide off the old boot. Wash the outer CV joint in clean solvent, then rinse it with brake system cleaner.Inspect the outer CV joint by rotating it to expose the bearings, inner race, and cage. Inspect the bearing surfaces for signs of wear. If worn, replace it. For reassembly, slide the new outer boot and small clamp onto the drive axle. Wrap vinyl tape around the shaft splines to prevent damage to the boot. Remove the tape. Install a new inner race retainer ring on the shaft. Pack the CV joint with approximately 5-ounces (140of CV joint grease. Force the grease into the joint with a wooden dowel. If the specified quantity of grease can't be packed into the joint, place the remainder in the CV joint boot. Tap the outer CV joint into place with a hammer and woodblock. Slide the boot into position, add the remaining grease to the CV joint boot, adjust the boot's length, equalize the pressure inside the boot, and install the new clamps. Install the drive axle.

You need to watch the steering linkage and suspension parts on Frontiers and Xterras. When they get worn or broken, your tires will wear faster, your ride won't be good, and your fuel costs will go up. To judge how well your shock absorbers or struts work, park your vehicle on a flat surface, shut off the engine, engage the parking brake, check the tires' pressure before starting. Press on one side of the vehicle and watch how it comes back down. If it keeps moving instead of stopping and bouncing back down, you may need new shock absorbers or struts. Use jackstands to lift your vehicle safely. Inspect the shock absorbers and struts while the car is on stands. Look for leaks into the fluid and make sure both parts are well-attached and working correctly. If you find any damage, replace the entire system as one unit. When checking the steering and suspension system, look closely for problems where control arms meet at the bushings and steering gear. There should be no liquid leaks around this area. Clean the area below the steering knuckle. Have a helper move the tire back and forth while you watch for movement at the balljoint. Changing the balljoint is needed if you see movement. Squeeze the outer edges of each front tire. Look for play in any moving parts of the steering system while checking for worn idler arm and tie-rod ends. Every 4WD model should get checked: look for breaks or tears in CV Boot, and replace them when you see loose attachments or signs of lubricant leak.

When inspecting the steering and suspension components, you should check for damage, distortion, and leaks. Pay attention to seals, boots, bushings, control arms, tie-rod ends, and ball joints.

The steering linkage and suspension components should be checked periodically because worn or damaged parts can lead to excessive tire wear, poor ride quality, handling issues, and reduced fuel economy.
