Knock when turning left. Noise getting more frequent and happens now over speed bumps. I have some mileage on my car and assumed normal wear, but same problem.

Yep struts went my 2010 altima hybrid at 68K what a piece of junk. I also have a 97 altima and my mom have a 05 altima struts still running strong, but the have been plagued with problems with ball joints, upper and lower control arm issues. Brother in law has two maximas and the 06 transmission blew just under 90k miles.
when traveling 20-30mph, and moving wheel back and forth, when wheel is moved to the left thumping/clunking sound coming from right front corner of car
