Just noticed this thread. I too have very stiff seat runners. Has anyone made any photos of what neeeds to be done?
Sorry Peter, no photos and the last one I did was someone elses car. Simple to do, first question is do you have any kind of wooded packing piece under the lowest part of the seats metal frame and runners? If you do you need to check if the bolts that hold the frame to the strip of steel (flat black bar) used to bolt the whole shooting match to the car have a clearance hole in the wood. Many are misaligned, if there is no wood lift the seats and look for marks where the bolt has been hitting the carpet under the seat in line with the mounting holes (so the fix cant be seen when done as its covered by the runners). If there is a mark then pressure is being put on the runners that will slightly bow them and cause the tightness so using a flat wood drill relieve the floor to give a pocket or hole for the bolt/nut. Don't worry if you break through there is a massive hole a few inches away where the front shackle pin is anyway, one more will not hurt (plus read on), this will take the bow load off the runners, grease the mechanism and work a few times over full travel to spread the grease and refit the seats. If you have gone all the way through (I always do) you can if you wish pop under the car and fill the hole with instant gasket, silicon or even a dab of underseal, it will make no difference to the car but I know some owners like to seal everything up.....I was raised on Allegros in the workshop where holes in the floor to let water out were seen as highly desirable
