Get quick struts. They're awesome.
Also, there is a rebate promotion until the end of April when you buy 4 shocks and/or struts. So if you're going to replace the front struts, replace the rear shocks too.
KYB has a $40 rebate
Monroe's rebate is $90 for 2 quick struts and 2 shocks
Gabriel's rebate is 20% (max rebate $125)
BUT since Gabriel doesn't make quick struts for your car, that leaves Monroe and KYB.
My recommendation would be KYB quick struts up front and Gas-a-Just in the rear.
When did you install the Sensens on the Maxima? Chinese shocks/struts are junk that rarely if ever last beyond 10k. And Sensen doesn't make quick struts for your van, either.
And like others said, stabilitrak has nothing to do with the suspension.
