How to service and repair the axle shaft assembly on Mercury Mariner?

You should start axle shaft assembly servicing by first placing the vehicle in neutral mode while hoisting it into place. First, remove the tire and wheel from the vehicle before you discard the wheel hub nut. Begin service by taking out the bolt which secures a speed sensor part and set the sensor unit to the side. Lower down the ball joint bolt and nut before throwing them into waste disposal. Maintain the ball joint stud away from contacting the CV joint boot when you disconnect the lower arm from the front wheel knuckle. The front hub remover should be used to disconnect the axle shaft from its position on the wheel hub. The axle shaft remover and slide hammer should be used to pull the left axle shaft out from the differential area. A brass drift will help strike the right axle shaft at the designated location to extract it. The left axle shaft installation requires alignment of its splines with differential side gear splines followed by pushing it into position until the bearing retainer circlip snaps into place. The installation procedure involves inserting the right axle shaft into the intermediate shaft splines then feeding it until the circlip creates a firm connection between the shafts while applying specified grease on the splines. Position the front wheel hub into the axle shaft installer before inserting the axle shaft followed by fitting in the lower arm to the front wheel knuckle. Fasten the new lower ball joint bolt with its nut by applying 63 Nm (46 lb-ft) torque. Fasten the ABS wheel speed sensor by torquing its bolt to 9 Nm (80 lb-in). Statements show it is vital to avoid nut tightening on the front wheel hub when the vehicle rests on the ground since this action damages wheel bearings; users should first place new front wheel hub nuts before applying brakes to stop axle shaft rotation during tightening to 300 Nm (222 lb-ft). The last step involves installation of front tires and wheels followed by checking and filling the transaxle fluid when needed.

The Axle Shaft of Mercury Mariner vehicles is a critical drive component that transmits power and torque from the vehicle's differential towards the driving wheels enabling independent rotation for improved tractions. There are many types of steel shafts for the car; the solid axles for the trucks and previous RWD vehicles and half-shafts for the cars which are utilized with the independent suspension systems. Differentials and axle shafts are located in solid axles and half-shafts connect the transaxle to the wheels. The axle shafts decrease their durability due to rubbing against different obstructions, and some of the problems may include noise and vibration; the seals being worn cause leakage of the lubricants and contamination of the brake. In general, the Axle Shaft has major functions such as to bear the load of the vehicle, convey the torque and enable the wheels of Mercury Mariner to stay in the correct position.

Q: How to service and repair the axle shaft assembly on Mercury Mariner?
A:
You should start axle shaft assembly servicing by first placing the vehicle in neutral mode while hoisting it into place. First, remove the tire and wheel from the vehicle before you discard the wheel hub nut. Begin service by taking out the bolt which secures a speed sensor part and set the sensor unit to the side. Lower down the ball joint bolt and nut before throwing them into waste disposal. Maintain the ball joint stud away from contacting the CV joint boot when you disconnect the lower arm from the front wheel knuckle. The front hub remover should be used to disconnect the axle shaft from its position on the wheel hub. The axle shaft remover and slide hammer should be used to pull the left axle shaft out from the differential area. A brass drift will help strike the right axle shaft at the designated location to extract it. The left axle shaft installation requires alignment of its splines with differential side gear splines followed by pushing it into position until the bearing retainer circlip snaps into place. The installation procedure involves inserting the right axle shaft into the intermediate shaft splines then feeding it until the circlip creates a firm connection between the shafts while applying specified grease on the splines. Position the front wheel hub into the axle shaft installer before inserting the axle shaft followed by fitting in the lower arm to the front wheel knuckle. Fasten the new lower ball joint bolt with its nut by applying 63 Nm (46 lb-ft) torque. Fasten the ABS wheel speed sensor by torquing its bolt to 9 Nm (80 lb-in). Statements show it is vital to avoid nut tightening on the front wheel hub when the vehicle rests on the ground since this action damages wheel bearings; users should first place new front wheel hub nuts before applying brakes to stop axle shaft rotation during tightening to 300 Nm (222 lb-ft). The last step involves installation of front tires and wheels followed by checking and filling the transaxle fluid when needed.
