  Q: How do I remove front Wheel Hub for Buick LaCrosse?

  A: To remove the front suspension on all models except 2010 and later models with RPO GNB, first loose the driveaxle/hub nut as well as the wheel lug nuts, afterwards lift up the car at its front until it is supported by jackstands. Remove the wheel and, if equipped, disconnect and detach ABS wheel-speed sensor electrical connector. Remove driveaxle/hub nut and brake caliper, caliper mounting bracket, and brake disc from hub. Next take off the hub/bearing assembly mounting bolts from behind Steering Knuckle throw them away. If necessary use a puller to draw hub and bearing assembly off in case driveaxle splines stick in hub. For installation see to it that both inner mount surface of steering knuckle and driveaxle splines are smooth without burrs or nicks here apply multi-purpose grease on driveshaft axles then push the bearing assembly down fully along into steering knuckle up to when you feel it seating properly after what tighten new set of these ones securing this assembly to steering knuckle by specified torque values. Connect wheel speed sensor harness connector where applicable fasten it at its bracket then insert but do not completely tighten drive shaft axle nut now add brake rotor caliper support bracket or even caliper making sure fasteners meet torque specifications provided herein above again bolt on wheel as well as lug nuts lower vehicle taking out jack stands finally make sure that you tighten properly rear end axle nut together with tire fastening bolts onto recommended torque values for 2010 and later models having RPO GNB front suspensions follow identical initial action items such as loosening drive shaft axle nut plus lug nuts supporting automobile using jackstands only lift these jack stands by jacking beam without resting your vehicle's beams onto them remove tyre before pulling out front suspension yoke itself coupled with steering knuckle from their places here unscrew ahead primarily used to keep wheels turning out further thus attaching those onto knuckle fasten with new ones tightening these by given torque specs hence insert steering yoke as well as front link into their actual position.

  Q: How do I remove rear Wheel Hub for Buick LaCrosse?

  A: To remove the hub and bearing assembly at the back of a model more than 2009, first of all slacken off the lug nuts at the rear wheel and block the front ones. Then raise vehicle rear-end and secure it with jackstands. Before doing so, take off both rear wheels and brake disc. After that, disconnect wire harness of wheel speed sensor if there is an ABS-equipped car. Lastly, unscrew for hub mounting bolts and detach from knuckle as well. For installation purposes, reverse what was removed, ensuring to correctly install the hub/bearing assembly in preparation for ABS wheel speed sensor if available. Finally tighten up new hub/bearing mounting bolts to specified torque values. Adjust parking brake; install tire using lug nuts; lower vehicle; then finally tighten lug nuts to specified torque values (if provided). However, it should be noted that for models made on or after 2010, it will be slightly different from this as stated hereunder: Loosen rear wheel lug nuts while drive axle/hub nut is left untightened on AWD models only. Jack up rear part of vehicle high enough above ground level before setting it down on jackstands so that you would no longer need tires anymore. Put blocks in front of the wheels to prevent rolling while removing a wheel on this side only (if applicable) because without which it might be dangerous since there could still have been some motion out from underneath each one them unless another precautionary measure such as those mentioned above were taken into account beforehand! On AWD models only if they are equipped with remove rear drive axle/hub nut too subsequently along removal also abs look like disc will fall over at last even though this depends upon whether somebody's own specifications/guidelines differ further about . If RPO GNC type of suspension is equipped by model then upper Control Arms have to come away accordingly." Incidentally ,Coil spring must be removed when this type of suspension does exist on it (advanced car thought without pointing out for example how complex that design has been made). Detach hub and bearing assembly from knuckle by taking out bolts. In case of AWD models, guide drive axle stub shaft from its splines within it's hub so that can be removed when stuck using rubber mallet hit into place with brass hammer or puller if necessary until release . The hub/bearing bolts are tightened as per the same torques in which they were loosened off while removing them earlier. On AWD models, tighten the drive axle/hub nut to specified torque values only; and lastly, mount caliper mounting bracket as well as caliper mounting bolts then wheel lug nuts must be fitted prior lowering down a vehicle whose lug nuts also will just get tightened at certain predetermined levels.
