I'm about to replace the driver's rear hub on a 91 Legacy turbo AWD w/ ABS. I need some help. Anyone have step by step instructions, including the tools I will need and other relevant info such torque specifications, common problems, etc. Thanks.

Lots of WD40 or other good penatrating oil. Let it soak for a few weeks ahead of time.

 

17 and 19 mm 6 point 1/2 dirve sockets.

 

Socket for the axle nut

 

Large breaker bars.

 

Rust will fight you all the way. The bottom strut attach bolt that goes to the arm may be rusted tight at any place along the length of the bolt.

 

Use a punch to drive out the axle nut locking punch mark

With the car on the ground and brakes set, break the nut loose.

Remove the tire

Loosen the bottom bolt that holds the knuckle to the arms.

Remove the brake caplier and disk

Remove the 2 bolts holding the knuckle to the strut

Drive the axle out of the hub

 

Replace any bad parts and re-install

Thank you. I'm starting at 6:30 AM tomorrow. Also replacing rotors and pads all the way around.

Here in the rust belt, wd-40 is useless. PB Blast or Sea Foam Deep Creap are the only things I've found that will touch the rust welds the belts get here.

 

Plan on replacing at least the long bolt on the bottom.

Almost done putting it back together. Hardest part was putting the damn e-brake back together. Job went smoothly all in all.

Just took a test drive. Very quiet but ABS light came on. Restarted and it seemed ok.
