I have a 76 280z, basically stock. It has some suspension issues, the rubber is getting old (cracked), the rear passenger shock has about 1-2 inches of not damping, and the aligment is pretty clearly off, it pulls to the left under normal driving and to the right under braking.
I was already planning to replace the rubber underneath, and the shocks and probably the springs (if I can afford it). Since my rear tires have worn down to the metal in less than a year, I'm suddenly motivated to get this all done before I go buy new tires and get an alignment.
My question is if my tires have worn so bad because of poor alignment, or if there is another possible culprit I should know of? I feel like I read something about u-joints or bearings wearing out and causing tire wear, but I couldn't find it through searching.
I attached pics of my rear tire compared to my front tire, the rears are half gone, and these were all bought less than a year ago.
I'm ordering parts tonight, and will be getting new tires and an alignment after everything is installed, so any warnings or tips regarding this issue will be greatly appreciated. Sorry if I'm long winded, I didn't want to leave anything out.
