Replacing axle carrier bearing--need slotted socket
 

Today I dropped the driveshaft to replace the axle carrier bearing. '66 w110 230. I took the driveshaft apart at the intermediate U joint and found a slotted nut that I need to remove to get to the bearing. It's 39mm across with 6mm tabs 90 degree apart. I tried to turn it after removing the staking with a punch, but no go (I don't want to screw the pooch here). Does anyone know where I can find this tool?

Also, I was going to replace the pinion seal while I was in there. It, too, takes a slotted socket. I would appreciate anyone giving me information as to where I can get these tools. I googled the tool and couldn't find anything.

They are available here, look at the 'buy parts' tab at the top and then 'special tools' and click on it. you will need to search for your special tool.

Thanks, guys. I finally found the tool at ZDMAK but it's about $60. I'll give it another try with a ground and profiled drift punch (thanks Mr. Dalton) before I buy it.

I use a punch all the time to undo them ,mainly because i am going to replace the nut , but what you can do is check out a place that sells used tools,such as pawn broker. Buy a 1/2" or 3/4" drive 36-38 mm socket and use a disc grinder to shape the four tangs .Dress it up with a file and you have your tool.

I've done this a few times on 722.1 and 722.3 transmissions that also have 4 pronged on the end. In the case of these transmissions there are newer 12 point socket type nuts that replace the older 4 pronged socket type nuts. So in the case of the transmissions there's no need to buy the tool so long as you don't need to fit the older type nut.

Thanks, everyone. The ground punch worked and I was able to replace the intermediate bearing/bushing and return the nut to its indexing without damage to the nut.
