67 230sl rear axle

Trying to replace rubber seals on trailing arms, I've managed to remove one of the nuts, but the other 3 aren't cooperating, wondering if there is a special wrench for this process? It's a 36mm but a regular wrench doesn't get enough bearing and wants to slide off rolling the edge of the nut. Got lucky on one, not so much on the rest.

I used a wrench as shown and in addition ground on side down a bit, removing the chamfer, to get the most surface contact. I also heated the nut after soaking in WD-40 for a while. After that, a couple of blows with the hammer and they came loose.

Yea, on my way to the harbor freight to get a socket to grind the chamfer down.

Better picture. I also attached a C-clamp to keep the wrench in place.
