Metric? Figures... now I have to go out and buy another tool!
LOL... Anyways...
For re-assembly using an adjustable wrench, is the proper torque setting of the nut not very important?
If memory serves me correctly, the torque setting (big nut at the control arm) is 130lbs. However, I just use my 12" adjustable wrench and my foot. Its recommended to use some Locktite on the threads with that fastener. If you look closely, you can see residue from the original thread lock.
For the 2 nuts at the frame, I just use german torque specs... goot-un-tite
If you want to get it close to the previous caster setting, count the number of visible threads before you remove the nuts and reinstall with the same count visible.
OK, just for review. The big cap nut at the control arm is about 30mm.. Use a big adjustable wrench, locktite, and foot torque. The 2 nuts at the frame are about 18-20mm.. Use a not so big adjustable wrench, count the threads, and tighten sufficiently.
One other thing, which may not have been mentioned, when you go to take these fasteners off, or to apply final torque, you will need something to keep the rod from spinning. I use an adjustable wrench to grab onto the rod and wedge it behind the swaybar. Be sure to keep it away from the bend in the middle of the rod. 2 inchs or so away from the "V" center should work.
