Have read WSM and still cannot figure this out.

Removed front end with spindle and swivel pin still on brake drum. See pic. I have wire wheels. I could remove the upper trunnion while swivel pin still on drum plate. Cannot turn the lower one as it hits the plate. Not sure how to remove the spindle.

When i start to loosen the four nuts on the swivel pin plate it seems that there are bolts inside that are coming loose. So, if I undo all the way, seems i will need to remove brake drum to reassemble. I don't want to do so until i know i can do this, and it may be easier to remove the plate once drum is off?

Suggestions?

Also, when putting everything back together what is recommended grease? Someone had mentioned impact grease (used in impact guns??) saying it does not drip as much and less messy.

Lastly, what oil to put in steering box, as I replaced boot and lost oil. Does it matter that i might be putting something different in than before? How much to put in?

Thanks in advance

The drum should be removed to allow access the the bolt heads. The backing plate needs to be removed in order to remove the lower swivel.

Any good chassis grease will work just fine for the swivel and bushings. 90 wgt gear oil for the steering rack.

Be sure you re-fit the backing plates on the correct sides, and facing the right way. It's easy to get them wrong.

You need a puller to remove the drum from the stub axle - do NOT use the 3-arm puller that hooks on the outside edge of the drum, as you will probably chip off the edge of the drum and disturb the balance of the drum. You need a puller that bolts under the wheel studs, which will quickly remove the drum. It may well leave the inner bearing on the stub, so you will need a different puller for that..

That will reveal the backing plate bolts, which you can remove easily.

Robert,
LaVerne has explained it above-remove the drum to obtain access to the bolt heads. I would not have removed the kingpin with everything attached.

He will probably have to replace the A-arm bushings with poly, so no harm. It's just a bit clumsier to do it off the car - how else do we learn if not by making mistakes?

This is the drum puller I use and when you consider the supported weights involved it is much easier to remove the drums and backplate with the kingpin still on the car. Be very careful witth your brakelines.

I've removed the drums lots of times from my wire wheeled TF with a block of wood and a mallet. Block of wood against the back of the rim and tap, rotate a quarter turn and tap, rotate again and tap, etc. Never fails and no damage. If you want to be extra cautious use a longer block of wood with a curve to match the drum circumference. Never hit the drum directly.

I found even with the heavy puller it took little effort to remove the drums so I would say Dave's method would have worked on mine too.
