My Durango drivers seat has electric motor adjustment 8 ways. All works well except the front to back. Only problem with fron to back is that when you arrive at the position you want, there is slack. That is to say if you adjust it to half way, when you hit the brakes or accelerate the chair will slip 1/4 inch like it is loose. Only way to get the seat to remain locked is to run it either all the way forward or all the way to the back.

Please advise if anyone has seen this problem, and if so how did you fix it. ?

Thanks
