93 940 power seat tracks out of alignment

Post by e777 »

So, thanks to Robert DIY's YouTube vid https://www.youtube.com/watch?v=7sQB-xR1daE I managed to fix the driver's side power seat, which used to not slide forward and backward.

However, when I went to bolt the seat down, I could see that the seat tracks were out of whack: one sits more forward than the other, meaning that the bolt holes no longer align.

Any tips on how to realign the tracks? I fear this could be a painful job....

Thanks!

The two sides are out of alignment. Look at them again and align them. Use diagonal measurements to check for square when adjusting the two sides.

Thank you, sir. Any tips on *how* to do the realignment? I have no clue as to how to begin to do that. Thanks.

I am not directly familiar with the power seat drive, but I expect there is a drive shaft powering both seat rails. If you have had the drive apart for repair, you likely got one rail ahead of the other and out of alignment. Rework as needed.

Yeah, it's actually a pretty complicated affair. The tracks appear to not self-align when running the disconnected seat back and forth numerous times. To disassemble the tracks look like it would be a nightmare. I may just ditch this absurd power seat and replace with a headache-free manual one.
