Last summer started getting vibration in the rear end of my 83 280ZX non turbo coupe when car under load. Local Nissan dealer replaced one u joint and it helped quite a bit, but not completely. (Didn't help my wallet by the time I paid labor plus diagnostic time). So, am going to put in four fresh ones. Any tips on best way to do this, for instance, when I put the car up on frame jacks do I need to support the rear wheels, etc? Mark

You don't want to support the rear wheels....you want them to be in full droop so you have better room to collapse the section and can rotate the half shafts. I'm sure its been done while supporting the wheels but when you have to rotate the half shafts for good access to the fasteners, your sunk! Other than that, its a typical U-joint replacement deal.

Much appreciated, have got a lot of stuff to get done on the car before the end of April and this is one of the more important things. Thanks, Mark

Couple of 3/8" extensions (about 12" each) help out quite a bit also...sure beats banging you head around in the wheelwell..

Thanks, I'll make sure I use the socket extension. Mark
