As a one man job taking the bar off is a lot easier than putting it back on.

I usually tie a rope around the bar and swing it from the steel truss in the garage via a couple of pulleys so I can raise and lower it easily. With a highmount winch bolted to the bar it sure does take a lot of the strain out of the job and I see no reason for injuring myself if I dont need to.

I have also have found that the highlift jack can be handy for 'aligning' the bar when you put it back on.
