Power seat front/back binding...

[ATmarine]

Well for a while both front power seats have been binding. It is not that they do not slide front and back, but the poor motor really struggles to move the seat. I thought I would just clean and lube the sliding track. I removed the seats, and disassembled the slider. There is a teflon (or similar) slider about 6” long, with a steel ball at both ends. It is this ball that is really binding things up. Without them the track slides very freely, and not really sloppy. It seems that the steel balls are the wrong size. Is this a possibility? Does anybody out there know if there was ever a service bulletin on this? The tracks and slider part wer relitavley clean, not filled with years of dog hair and crumbs as I had expected. I doubt the seats have ever been out of taked apart before, but you never know.
I struggled with this for a while, and it is definitely the ball that is causing the binding, and hard sliding. I reinstalled for know with only the teflon slider, and the seats work very nice and smooth as power seats should. Has anyone else ever encountered this before? Thanks!

My seat did that, but only for the reason that they had years of crap- I took them out and cleaned the track and that fixed the problem. You might be able to go and snatch up some rails from a junkyard for cheap and see if that works- If so, problem solved.
Not sure about the compatibility of the seat rails, but i'm going to take a guess that any 95-97 850 rail should work. Or if not, just take another apart and see if they have the same size balls?
