Seat Track Guide Repair - Or How To Stop A Wobbly Seat.
Ah, yes, the thrifty MKIII line. Made up of choice left over MKII parts... Which was made up from left over MKI parts... designed in 1973... Like... the seat guide design. Sure, it looks great on paper, but in real life, 100,000 miles later, and 20 bazillion times of you and everyone else moving the seat... falling french fries, dimes, and so on.. it starts to wear out. And before you know it, its like a bad sicko twisted hobby horse ride of doom.
|So lets get started... shall we...

If your car is a 1999 or later car ( a MK 3.5) make sure your battery is disconnected before you remove the seats! Your seats have side impact thorax airbags in them.. They will set an airbag code if you unplug them with the battery hooked up! Make sure the seats are safely back in the car and plugged in before you reinstall the battery. If you are unable to disconnect the airbag wire from the seat, do not cut, alter or attempt to repair this wire! Personal damage or injury can result!
Step 1 - Open the door, and look at the front of the seat, push it all the way to the back of the car...
You'll see a thing that looks like this... this is the OBD1 style seat retainer. This style just gets squeezed to push it out of its little tang. OBDII cars use a 6mm Allen head bolt and a 10mm nut.
On the drivers side, reach under the seat and unhook the seatbelt warning wire. Feel free never to hook it up again....
Step 2 - Remove the rear seat track covers. These just pop off by hand. Wash them off with soapy water.. I am sure they are very nasty.
Step 3 - Place towels in back seat area behind seat track guides. This is to keep grease off the carpet. Its nasty.
Slide the seat to the rear of the car, lift up on the seat adjuster, and push the seat all the way back to the rear of the car.
On a Jetta or 4 door Golf this is best done from the back door. On a GTI its best done from the front seat. Two people might be helpful. If you have a Jetta Coupe, you are a moron. You made that car, and your reading this? WTF?!
You should have the seat out of the car, the tracks exposed, and the front guide exposed.
Damn, that's nasty. That seat guide, the nylon part just comes with a little pry from a screwdriver.
Step 4 - Vacuum out the crud. Wipe out the seat guide rails.
Now is a great time to really clean your carpet and center console too...
Step 5 - Walk the seat over to your sturdy work surface. Mine is an old door on two saw horses. Rock solid!
Step 6 - Match up ole' nasty with the new kid on the block.
Step 7 - Pop the old one off.
Not only is it nasty. Its also worn down quite a bit. I have seen these where they are worn all the way down to bear metal.
Do this for the other side... and don't mix them up! Install your new parts on the seat.
Step 8 - Clean up what's ever is down there..
See that red thing in the middle? That's the seat belt warning. Cabrio owners with airbags have a larger yellow plug down there.. Lube the center track a little, a thin film is all that is needed.
Step 9 - Put it back in the car, carefully.
Use your plastic safe silicone based grease to lube the tracks and guides. A small bit goes a long way.
Test out the seat sliders... should feel like a new car again! Enjoy!
