Exceptional Quality GM OEM hardware., Bearing pre-pressed and lubed in hub, took less than 5 minutes to install. Cleaned spindle thoroughly and used lots of synthetic bearing grease on spindle before sliding new hub on. For 2009 / 09 Aveo ( Aveo5 ) - Spindle nut is 32mm for those who have asked. For job you need the Amazon Prime items below: (a 32mm axle nut socket and to get rear drum off (no need to take brakes apart), brake cleaner, Phillips impact driver, bearing grease (I personally use synthetic or lucas green). Bearings come pre-lubed, pressed, and ready to go. There is no need to take apart to lube. Remove old drum, (two phillips on drum remove w/ impact driver) clean w/ brake cleaner. Remove spindle nut w/ 32mm socket. (If you don't have an impact gun you can use a 1/2" breaker bar). Slide old hub off. Clean spindle and parts w/ brake clean. Generously lube spindle w/ bearing grease taking special care not to get lube on any brake parts. Quick spray new hub and let dry, with brake clean before sliding on. Tighten spindle nut to 140 ft lbs. Carefully push dust cap back on. Careful not to bend/crush. cap. (I lightly coat all threads of wheel studs and spindle with antiseize shown below as optional. Some tools below are homeowner grade for affordability. Always use hand and eye protection when working. Always support a vehicle with a static jack stand. Never support a vehicle with only a jack. Never trust homeowner grade jack and jack stand to support vehicle so you can work underneath it. Always use jack stands and jack ABOVE rating of total vehicle weight. (Example, SUV we use 8 Ton stands as GVW can be right at 4 Tons total for Trailblazer SUV) jack stands should support weight when working, not jack. Again, NEVER work under vehicle when using jack and jack stands. It can cause death.Wheel hub https://www.amazon.com/dp/B000EQS3CW/ref=cm_cr_ryp_prd_ttl_sol_0Impact Driver: https://www.amazon.com/Powerbuilt-648002-2-Inch-Impact-Driver/dp/B004QO9FK2/ref=sr_1_51?srs=3039007011&ie=UTF8&qid=1490901063&sr=8-5132mm Impact/Axle Socket: https://www.amazon.com/Powerbuilt-648470-2-Inch-Driver-Socket/dp/B002INUR14/ref=sr_1_4?ie=UTF8&qid=1490901288&sr=8-4&keywords=32mm+impact+socketBrake Cleaner: https://www.amazon.com/CRC-Brakleen-Brake-Parts-Cleaner/dp/B000LDR9HI/ref=sr_1_43?rps=1&ie=UTF8&qid=1490901525&sr=8-43&keywords=brake+cleaner&refinements=p_85%3A2470955011Bearing Grease: https://www.amazon.com/Valvoline-VV986-SynPower-Synthetic-European/dp/B000GAN3I0/ref=sr_1_2?ie=UTF8&qid=1490901662&sr=8-2&keywords=synthetic+bearing(Optional) Antiseize: https://www.amazon.com/Permatex-80078-Anti-Seize-Lubricant-Bottle/dp/B000FW7VGE/ref=sr_1_1?ie=UTF8&qid=1490902131&sr=8-1&keywords=antizeizeBreaker bar: https://www.amazon.com/TEKTON-15355-2-Inch-by15-Inch-Breaker/dp/B00MWVAUT6/ref=sr_1_7?ie=UTF8&qid=1490902291&sr=8-7&keywords=breaker%2B1%2F2%22&th=11/2" Torque Wrench: https://www.amazon.com/Locking-Extension-Sockets-contained-Bastex/dp/B01N0TKEAZ/ref=sr_1_cc_2?s=aps&ie=UTF8&qid=1490902499&sr=1-2-catcorr&keywords=1%2F2%22+torque+socket+wrench
