[QUOTE="ShelbyGuy, post: 3989349, member: 10042"] This is a job that takes a few specialty tools, and there are a couple of nuances to the job too. 1) Remove knuckle from the car. This will be covered in a seperate write-up. 2) Remove dust shield. On a Cobra, these are 10mm hex head bolts. Ford recommends replacing them, but probably to give it fresh threadlocker. Life is too short for a car with shielding that rattles. 3) Press out the hub. To do this, we need a press (thank you captain obvious), step plates, and a way to support the knuckle. I use the Ford/Rotunda/OTC tool specific for this job. Day one of Auto Mechanics 101 - use the right tool for the job. BilletFLow supercharger pulley puller used for size comparisson. [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0002.jpg[/img] This is a step plate that fits perfectly in the hub [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0004.jpg[/img] Pressing out the hub (dont laugh - I know I need more press plates) [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0006.jpg[/img] And out it comes. [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0009.jpg[/img] 4) Take out the giant snap ring. Cheesy snap ring tools need not apply. Getting this guy in and out is the hardest part of the job, in my opinion. [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0013.jpg[/img] Here is what we have apart so far: [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0017.jpg[/img] 5) With another step plate (every press user needs a handful of these little buggers) of the right size, press out the bearing. I'm using the Ford/Rotunda/OTC tool specific to the job of supporting the knuckle. [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0020.jpg[/img] [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0022.jpg[/img] And out it comes. [img]http://nitro.vapornet.net:16080/my03cobra/RearWheelBearing/image/dsc_0025.jpg[/img] To replace the bearing and hub, its mostly a reverse of the removal process, but some of the step plates are different.
