How can you tell whether you have a hub bearing assembly or a press in bearing style? You can check your local parts store, website or Subaru parts catalog. Most 08+ Subaru vehicles moved to bolt in style bearings and a few before that. You will find front bolt in bearings on a 2005 STi but the rears are still press in. A 2005 Impreza, Wrx and Forester will all have press in bearings on both ends but a Legacy/Outback will have bolt in front and rear bearings, so just check your specific model and get the right parts!

Time

Installation time will be around an hour for those with quick hands, the proper tools and a bit of luck. For many others this can be a hour plus job, how well the bolts and parts will separate or stay seized together which can take many hours with the combination of luck and rust.

Tools

Grey Pneumatic 3/8th socket set: These will start off the list. You will need your 12, 14, 17 and 19mm sockets will help get this job going.
