Vauxhall Corsa Steering Rack Bush

thingiverse

In the end of the Corsa (and others) steering rack is a bush, it's a wear item but the motor factors want to sell a steering rack and not a bush. This seems to be a very common wear point in the Corsa (and others that use the same rack). The symptom is a lateral movement (forwards/backwards) in the nearside steering rack arm. If you hold the inner tie rod where it screws onto the rack and move it forwards and backwards you can feel the significant play. To change the bush, you remove the tie rod and pull the bush out and pop a replacement in. You can buy them off Ebay and they're not stupidly expensive but if you have a spool of nylon sitting around and fancy printing one, here's a model! In the photo, I printed in ABS just as a quick test to make sure that it printed ok (and I had ABS loaded) but for use i'd use nylon, like the original. Safety note: Obviously you use this at your own risk although it's not a load bearing part in the sense that it holds wheels on, it's a supporting bush to guide the long travel of the nearside part of the rack - it just wears with the constant dragging of the rack against it.
