Both my front seats strugle to 'click' into position if slid forwards or backwards unless the person takes their weight off the seat for a moment. Looking under the seat, the rod which engages into the holes to hold it in set position is lying a little low(hence if the person sitting takes their weight off it clicks into place). Was wondering if this can be adjusted in any way or if its just sagging due to age, car is a 1996 1.8t sport. Don't know if this is anything to do with it but both seats are also a bit shaky and move from side to side when getting in or out. Thanks.
