Your car alternator isnt charging the battery hence in first place as per proper diagnostic you should be changing the alternator not the battery. Sorry for waste of money for battery.

RTFM Read the fucking Manual mate I know we all hate it, but sometimes like this they are your best friend. Also read this google searched article for you http://www.clublexus.com/forums/gx-firs ... -to-c.html

Check the ball joints and also get the wheel balancing done again.

Not on flat surface, but on slope its better to back with main brake and then release it.
