'87 560SL Loose Seat - Missing Guides/Bushes?

[gary560sl]

The passenger seat in my '87 560SL is loose in it's runners. i.e. it rocks slightly, whereas the drivers side is nice and firm. Could I be missing some bushes or guides which fit in the runners? If this is the case does anybody know where I can purchase new ones?

Sorry no one has answered this yet. There are nylon slide inserts that fit into the seat rails. It's been several years since I had my seats out, so I don't know if you could see them while they are in the car, but get a flashlight and maybe you will be able to see them in the driver side seat rails, which you say is solid. Not sure if these are available from a dealer. I couldn't find them aftermarket. Another possible is the bolts that hold the seat to the floor, which may be loose for some reason, likely a PO not securing them down, or a broken frame piece, which would be hidden inside the upholstery.

In addition to the nylon runners in the slides themselves, there is a black nylon (?) cover over the tab that fits in the plate that bolts to the car behind the seats and towards the rockers. One of mine was missing and it made the seat slightly loose. At the time, it was still available at the dealer and I replaced it.
