Does someone know how to remove the cup washers that are located around the threads on the front hubs of an 80 series

get a drift(something to place on the end of the stud that u can hit with a hammer that wont damage the thread, usually brass)

place the brass drift on the end of the stud, hit it hard with a big hammer, the shock will release the cone washer, u may need to pull it off with some pliers if they r real tight.

i have added a pic

Give them a squirt with some wd aswell , just to release them a bit then as above .

And if they have not been removed for some time, have some patience! Don't continutally belt the drift, seperate each hit with the hammer ensuring the drift is centered. For tougher washers spray with WD, hit a few (read: many) times and repeat. They can be a biatch sometimes.

I supplement the brass drift trick with the recommended procedure in the factory service manual to wedge a special tool in the opening of the washer. I made it out of a steel drift shaped such that side profile of the tip matches the cone washer opening.

Do you find this forces the washers out just by spreading the gap in the cone? I have tried this theory to no avail. What's your trick?

Also when putting it all back together grease the outside of the cone washers so they dont become corroded in place.

Yes, the trick is in the angle of the sides that touch the washer. It still does not work all the time so I use both the brass drift and this tool.

leave the nuts on a turn or so and smack the outer axle with a hammer next to the cone washer. Cause these are under pressure they tend to fly off atabout 20000 k's a second!!

Thats how I get the rears off for maintaining bearings...

I just give the hub a hit on the outside with a calibrated Knockonmeter (Hammer) right where the cone washers are. This shocks them loose real easy.

another method is to loosen the nuts a couple of turns (don't remove them) then go for a bit of a drive.

sometimes belting the stud will not work and will destroy the stud - sometimes it's better just to accept that you're going to fit new studs, and grab them with the vice grips and wind them out.

be careful if you use the hitting the drive flange perpendicular to the stud method - if you permanently deform the conical bores in the drive flange, the washers will not re-seat and you'll end up shearing the studs.

thanks for all suggestions. I ended up getting a copper ended hammer and hitting the hub next to the washers and after about 20 hits on each part of the hub they flew out one by one.
