Just want to thank you guys for replying. I'm new to forums in general so please excuse and mistakes. I'm a 21 year old from suburban NY. Before buying the Z I was actually searching for a s13 but came across a 240z and had to have it. Personally I haven't done anything to the car yet but the guy I bought it from claims he had a tune up done, a new clutch , and new brakes (I doubt he did anything). The car has a misfire and is not timed correctly but anyways back to the problem at hand. I do not know the vin # of hand but my car does not have the vents. Underneath everything is fairly rusted which is why I've been set on just replacing everything. A friend suggested maybe a cotter pin fell off while driving which is causing the left rear wheel to whobble. I've been away for the weekend so I haven't had a chance to get pics but will do so tomorrow after work. I will also get you guys the vin #. If I missed anything let me know and I'll try to cover that in my next reply which hopefully won't be so long . Thanks for the help!
