I got a 84 300zx and there is a noise coming from the rear when I shift
into second gear. When I used to own my 70 240z, this problem was the
rear drive axle that goes from the rear end to the wheel. on my 240,
the problem was apparent because when I touched and moved the shaft, it
moved and I could tell its the u joints on the drive shaft coming from
the rear end to the wheel but on my 300, when I touch it, it does not
move or have any slack. I hate to spend 75 bucks each to replace them
if I dont have to. Have any idea what the problem is?

It's probably the rear subframe mounts where the rear subframe attaches to
the body, common problem on those cars

Actually that problem (excessive rear camber) is caused by the lower control
arms twisting with age. Another very common problem these have and the
easiest solution is to slot the rear subframe mounting points to allow
adjustment. The only other solution is to replace the lower arms. I see
people replacing shocks, springs, wheel bearings etc trying to fix this, it
doesn't..
