To change a wheel, the lug nuts must be unscrewed, the vehicle has to be lifted and placed on jack stands before the wheel can be changed. Then, the tie-rod shall be detached from the steering knuckle together with removal of brake parts. Following that, remove the front axle axleshaft and unfasten the steering knuckle oil seal by using the oil seal retainer bolts. Turn to the upper Side to take of the steering knuckle arm retaining nuts ad cone washers, go down and take a hold of the lower steering arm assembly and pull down to detach it from the knuckle. Next, remove the upper bearing cap along with the shim, if installed, and then the steering knuckle, where one has to twist the upper bearing cap off. It is important not to mix the bearings hence label the bearings, and use solvent to wash out all the bearing grease from the bearings, axle tube yoke, and steering knuckle while ensuring that the bristles do not get lodged in between the roller bearings. The bearings should be in good condition and the bearing races attached to the inside of the axle tube yoke should also be checked for signs of wear; if they are worn one must drive out the worn race and install a new one with the bearing driver. Check and make sure the bearings are packed with high temperature wheel bearing grease and that there is grease film on each bearing race. Fit a new steering knuckle oil seal, then press the upper bearing into the axle tube yoke; position the lower bearing. Place the steering knuckle over the axle tube yoke and tighten the upper bearing cap, and spacer then put the upper bearing cap bolts. Refit the steering knuckle arm, cone washers and retainers and tighten the nuts by the required tightening torque. To check the bearing preload, use a spring tension gauge, tightening the nut further if the preload needs to be increased, and putting on the correct size shim if the preload needs to be reduced. Last of all, it is advisable to complete the installation by using the corresponding removal steps in the reverse order.
