  Q: How to replace the inner CV Joint Boot on a driveshaft on Volvo S40?

  A:

  To start, the Driveshaft should be removed and the clips on the metal should be cut to slip the gaiter from the inner CV joint. Clean out some of the grease from the joint, and make some alignment marks between the housing and the shaft to help in reassembling. Carefully disconnect the housing from the tripod, twisting the housing to force the tripod rollers out one at a time, if needed using a soft faced hammer or mallet. Clean the tripod and housing of the grease and remove the circlip and carefully drive the tripod from the end of the shaft, removing the circlip and getting ready to fit a new one from the repair kit. Now, remove the gaiter if it is still on the shaft, then push the new gaiter onto the shaft along with the smaller clip. Refit the tripod with bevelled edge towards the driveshaft forcing it all the way in until the new circlip can be fitted. Lubricate the tripod rollers with some of the grease from the gaiter kit and fill the housing and gaiter with the rest. Refit the housing to the tripod, tapping it gently into position if necessary and slide the new gaiter into position, making sure that the smaller diameter locates over the grooves in the shaft. Fit new retaining clips and refit the driveshaft, equalising the air pressure and then tighten the gaiter clip. It is suggested to lubricate gaiter from the outside after refitting the driveshaft with a little spray wax.

  Q: How to remove and service the outer CV Joint Boot on the driveshaft on Volvo S40?

  A:

  Remove the Driveshaft. For automatic models with a vibration damper, after removing the inner CV joint, measure and note the distance from the end of the shaft to the edge of the damper. Press the damper from the shaft, renew the outer joint boot, and then press the damper back into its original position using the noted dimensions. If a hydraulic press is unavailable, most engineering workshops can perform this task for a modest fee. For all models, cut off the gaiter retaining clips and slide the gaiter down the shaft to expose the outer constant velocity joint, taking care not to disassemble it. Scoop out as much grease as possible from the joint and inspect the ball tracks on the inner and outer members for wear. If the joints appear worn, complete renewal may be necessary. If the joint is satisfactory, obtain a repair kit from a Volvo dealer, including a new gaiter, retaining clips, driveshaft screw, circlip, and grease. Pack the joint with half of the supplied grease, working it into the ball tracks and the driveshaft opening in the inner member. Slide the rubber gaiter onto the shaft, apply the remaining grease to the joint and the inside of the gaiter, and locate the outer lip of the gaiter in the groove on the joint outer member before fitting the retaining clip. Remove any slack in the clips by carefully compressing the raised section with special pincers. Ensure no grease is on the surfaces between the gaiter and the joint housing. Use a small screwdriver to lift the inner lip of the gaiter to equalize the air pressure, then fit the inner clip. Fit the new circlip to the end of the shaft and, where applicable, press the damper into its original position, using soapy water to facilitate sliding. Check that the constant velocity joint moves freely in all directions, then refit the driveshaft. It is recommended to lubricate the gaiter once the driveshaft is refitted by applying a small amount of spray wax to the outside of the gaiter.
