Wheels have some play (actually a lot ) so i am going to change the wheel bearings. How can i tell if the axles need to be replaced? Ive kept up with the fluids but not the suspension and i think it needs work. Also the shifter does not go into high gear and can be impossible to shift when the motor is running - any ideas on what is causing this? Any special tools help with the repairs needed? I have circlips and most normal tools

Thank you for the help !
