Driver wiper loosens

Hello all my name is: Mike
I have a 94 3000gt base and the driver wiper sometime comes loose and pushes to the far left and stick while the right works. I’ve realigned and tightened it but it after a while it happens again. I was wondering if it might be the nut itself or the spline possible starting to round off. Have any of you had this issue and is there a way I might resolve it.
Thanks for any help

This problem is known to occur on most cars if the wiper has been removed at some time and not re-fitted correctly. The center part is made from steel so it should be ok if you clean it but the arm is made from a softer metal and the splines are often damaged if you don’t line them up properly or if you twist it when removing. Just take a good look at the splines and if they are smoothed off, get a new arm.

Thanks Joe I will do that, is there a source for new arms?

Check your local mitsubishi dealer. They are fairly standard so you should be able to get one.
