Just checked my LRDirect order for the nuts I ordered, the top is NY214047 and the lower NY216047. The shipping to France was more than the cost of the nuts! Doh!I have a pretty long breaker bar, 1/2" that I use with an extension tube as like you I am getting on and arm strength was never my thing! But it was OK for doing up the axle hub nuts on my rear axle so it ought to be OK. I would never use it with a ratchet, I broke my thumb the other day when a 1/2" ratchet "let go". Even more annoyed as I never start the nut with anything other than a breaker bar.
Still would love to know what size nuts I need to order with the ball joints but am going to check out the vehicle's history first before ordering the special tools.
More later when i have the time. Have yesterday had to position a ladder in a death defying manner, using ratchet straps, to measure up for, manufacture and fit bits of wood to our soffit's end to stop crows nesting in there. Lovely to wake up without the noise of blo ody birds scratting around about 2 metres away from our heads! So got up a bit too late! (Couldn't get to them from inside the loft!)
Don't envy you up that ladder - I don't do heights.
Cheers.
