How do you tighten the LCA shaft?

I’m with the other guys, a cheap *** HF grinder with a flap disk, two flats on the collar. And a cheap *** wrench from the thrift shop to customize for said job...

The greaseable LCA pens that Firm Feel sell have flats on the collar for a wrench.

I actually had a mechanic rebuild the front suspension. About 2 months later, he quit and the body shop told me my car was done. I put it on the lift at my house and notice the LS brake and spindle were on the RS, and vice versa. I am now checking the torque on everything the mech did.

While correcting that, I noticed the upper ball joints castle nuts did not have cotter pins - not torqued, either. Lower joints had cotter pins, but were not torqued. That’s when I saw the strut shaft and the LCA nuts were finger tight, no cotter pins. So, I grumbled, set the ride height, torqued the strut shafts, then tried to tighten the LCA shafts - no dice. I tried it loaded and unloaded. I’ve tried it with impact- nut stays and shaft spins.

So, tomorrow I will get smaller vise grips and try again. Next one, I will do - and those damn pins will be modified for a box end.

Last resort is to pull the LCA’s. Can I just pull the torsion bar and tap the shafts out from behind?
