The B15 class of Nissan Sentras includes the 2005 production year. The 2005 Sentra features two engine options: a 1.8-liter or 2.5-liter four-cylinder engine. It also could come with one of three transmissions. These different models, however, all feature the same wheel bearings and the same process for changing them. The wheel bearings connect the wheel to the axle. They can overheat or leak grease; if so, they need to be replaced. Expect the process to take at least an hour.
Pull the cotter pin from the axle rod with your pliers. Pull off the washer. Loosen and remove the large, central nut on the axle rod with a 30 mm deep socket, 1/2-inch ratchet, and breaking bar. Remove this nut while the Sentra is on the ground to use the weight of the Sentra as leverage.
Loosen the lug nuts on the wheel with your lug nut wrench. Raise the Sentra with the car jack until the wheel is off the ground. Place a jack stand under the Sentra. Lower the Sentra so it rests on the jack stand for added stability. Remove the lug nuts. Pull off the wheel.
Remove the two 15 mm bolts from the brake caliper. Slide the caliper off the rotor. Strap the caliper to the suspension spring with wire.
Pull the rotor off the wheel bearing hub assembly with your hands.
Tap the axle shaft in with a chisel and mallet to dislodge it from the wheel bearing hub assembly. Remove the three 15 mm bolts securing the wheel bearing hub assembly to the knuckle.
Connect the wheel bearing hub puller wrench to the wheel bearing hub assembly with the three bolts you removed earlier. Turn the shaft of the puller wrench counter-clockwise to unseat the wheel bearing hub from the face plate.
Place the new wheel bearings on the face plate. Place a deep socket over the new wheel bearings. Tap the wheel bearings onto the plate with a mallet until the wheel bearing race is seated fully against the plate.
Grease the axle rod. Mount the new wheel bearing hub assembly to the knuckle with the three bolts you removed earlier. Replace the rotor. Remount the brake caliper. Replace the large central nut you removed earlier. Replace the washer and cotter pin to the axle rod. Replace the wheel. Lower the Sentra to the ground.
