Hi,
A bit of a ramle - sorry
I know changing seat bushes is covered a lot and sorry if it has particular question has been mentioned else where.
Just been undertaking this task of changing these on my car - driver’s seat done, passenger seat to follow.
Looking on the likes of e-Bay I could find plenty of people offering replacement bushes. I purchased some of a UK company, who also had a helpful video on how to do the job.
The bushes supplied are made from solid plastic (Delrin I think) and the video stated that you sand these down until the threaded block will just fit in to the carrier and press it in the rest of the way with a vice. This means the threaded block is help rigidly in the carrier between the platic bushes.
Put everything back together and tried to move the seat and ..... nothing! The motor wanted to move but the system was jammed.
Looking at the old bushes (what was left of them anyway) these are not a solid material like Delrin and look like they are made from a synthetic rubber - probably SBR. With this I would expect that the threaded block would not be held rigidly, but would have a degree of movement. I am sure the threaded rods while generally straight, may not be 100% true and some movement of the blocks would overcome this.
Based on this I stripped down the runners again, removed the bushes and sanded them further so the threaded block fitted snugly, but was free to move. Put everything back together and hey presto, the seat moved fine.
Taking a look on e-bay again it would seem that some of the bushes available are made of hard plastic, but others are made from material that has a bit of flexibility, such as thermoplastic polyurethane which will allow the threaded block to move.
What has other people’s experiences out there? Have you used rigid plastic bushes with no issues, or feel bushes made of a softer material are the way to go? From my experiences, I would say the latter!
Regards,
Nick
