Shock Arm 1935
Did a lube job and noticed this on the right front shock. The rear shock arms have a clamp bolt arrangement to retain them but this looks like it was swadged on. Is this repairable, or do I need a new shock?

Re: Shock Arm 1935
Probably a new one or at least a good replacement. That's an unusual failure.

David: Can't that be pinned? Or welded, Or both?

Yes, if the shock is otherwise good.

Re: Shock Arm 1935
Dennis - are you talking about welding the arm onto the shaft? How about using some form of Loctite on the splines? They make many different types.

Re: Shock Arm 1935
Steve,
Good idea. I hadn't thought of that. In the mean time, I noticed that it appears that the shaft had been staked with a punch to retain the arm. I put the arm back on and re-staked around the perimeter with a center punch. I couldn't get a very powerful swing with the hammer, but we shall see. I drove about 10 miles and crossed two RR tracks and it is still on, but I will watch it and use your suggestion if it comes off again.

Re: Shock Arm 1935
Yes, I noticed how someone had gone around it with a centre punch. Rather than welding the arm on, [which is a bit crude, particularly if you ever want to remove the arm for any reason, you could put a couple of 'scotch keys' in it. What is a scotch key you ask....if you utilise a couple of your dot punches, you could drill and tap say 1/2" deep and fit a couple of grub screws. Half of each thread is in the shaft, the other half is in the arm, That will ensure the arm stays in place, and in the future, should servicing ever need to occur, the grub screws can be removed to enable arm to come off. just a suggestion....
