No reason to loosen the torsion bar adjuster. Support the car on the LCA and, as stated remove one bolt and a time, grease it, and put it back in. Nothing should get out of place that way as there really isn't any weight on the upper arm.
If you support the car on the LCA’s the suspension is loaded. That means there’s load on the UCA, and that means there’s load on those bolts.
Can you still pull one out at a time? Probably. But the suspension being loaded will just make the job harder. More likely to have a bind on the bolts, more likely for the UCA to pop out of place when the bolt is pulled, and stored energy in the loaded bars to bite you in the *** if something goes sideways.
No thanks. Takes a minute to unload the adjusters, minute to put them back. Count the turns on the way out and on the way back in and no problems.
