Hi - if you are driving an old Subaru with 4 WD; and need to replace the Rear Wheel Bearings - you will find that a Special Lock Nut Ring exists on the ‘inside’ of each hub - which MUST be removed to drive out and replace the bearings. This Ring Nut is installed with a torque of 127(min) to 163(max) foot pounds… Subaru calls out a ‘special’ tool to help remove the Ring Nut - p/n (WRENCH 925550000) The Repair manual doesn’t mention it - but this Ring Nut Wrench also has p/n of: SU-022

This tool is discontinued and is VERY hard to come by… HOWEVER - Performance Tool makes a similar tool which WILL work - after a simple modification… the W1271 (by PT) and available from various outlets such as O’Reilly’s or AutoZone and others for around $20 - works quite well - IF you CUT OFF two of the protruding ‘nubs’. 180 degrees apart. This leaves two nubs still on the tool - and it will NOW FIT the Subaru drive axle… and you can unscrew the Ring nut. The tool is not rated for ‘impact’ - but I found that worked quite well; and quickly got it unscrewed. I also weld - so I welded the two ‘nubs’ which I cut off - back onto the tool at the correct spot for the Subaru tool - to help it fit. Although that wasn’t really necessary. And If you just cut off two opposing nubs and don’t weld them back on - it actually would still probably work for the applications for which it is designed and sold… Just a heads up… the PT W1271 can be substituted for a Subaru 925550000 or SU-022 if you cut off two opposing nubs… When replacing older Subaru rear wheel bearings. :smile2:

It's known on USMB:

Spindle Nut Socket for rear wheel bearing on 80's Subaru's - Old Gen.: 80's GL/DL/XT/Loyales... - Ultimate Subaru Message Board

After years of fighting these with a straight punch I finally bought the correct Subaru axle pin tool. This REALLY helps a lot. If you don't have one I recommend getting it. If you can just get one joint apart on each side then you can pull the whole trailing arm and work it on the bench if you have to. You are also going to need a socket to get the rear bearing nut off. I couldn't find the correct 4 pin one so I found one that was close and ground 2 pins off.
Loyale rear wheel bearings won't budge and CV pin won't come out.? - Old Gen.: 80's GL/DL/XT/Loyales... - Ultimate Subaru Message Board

You can also weld "pins" to the side of an appropriate sized socket that slides into the ID of the retaining ring.
