steering wheel vibration while car is parked

my 4-cylinder 2.0 16-valve manual shift maxima has good performance but sometimes there is abnormal vibration that can be most felt when touching the steering wheel . at times this vibration disappears or decreases in strength. I must add that this vibration occurs mostly when the car is parked. it has 80,000 km on it and it is a 1999 model.

hate to tell ya this...you dont own a maxima

the reply by wunfstmax is entirely satisfactory and interestingly revealing...Because my car is a maxima clone that was built in Korea and named Samsung SQ5. Now because a car named Samsung SQ5 is literally not heard of on the web and because it was a necessity that I post this frustrating problem I decided to deliver my message using Maxima. Normally I purchase spare parts from the nearby Nissan shop.

I can not help with your problem but maybe you can help me. I have a Samsung here in Panama and need to replace the CV Joint or the complete Axle Shaft. Here is not dealer in Panamà. Have you replaced your shaft with the Maxima ones? I want to order to U.S.A. the Nissan shafts but I am not sure if It will fit my Samsung.
