I bought 3.5 se maxima 2004, 195 kw. There is one problem with my stearing wheel at 80 - 100.. Where is the problem? Tyre balance, warped plastic down the radiator or wheels alignment? And plus I want to ask how much oil (in litres) I need to buy for my maxima for engine and how much oil for transmision. Thank you!

 

Could need a tire balance, or you could have flat spots on one or more tires.

I actually broke a belt in one of my goodyear touring a/s tires and it definitely caused some shaking at higher speeds before a tech found a slight bulge in one of them. It was especially disappointing because it still had a good bit of tread left

Oil capacities

I'm not sure what transmission you have, but you should consult the owners manual if you have it.

 

Thanks a lot I will chek this. My transmission is cvt

 

Try a wheel alignment

 

You can rotate tires from front to rear and see if the vibration follows before rebalancing them but I would balance them anyway.
Is there more shimmy when braking from the HW speed? If yes, then your rotors warped.

 

Is that Slavic?

 

No, that's Lithuanian. Different people, different language group.
