Report suspension bushes in Suspension/Brakes/Wheels/Hubs/Steering/Geo Posted November 21, 2012 In the interest of safety. Those that fitted the PUK bushes to the front upper wishbone arms, check they're still secure. The PUK ones do not have a bonded outer component and that means the upper wishbone arms are free to slide back and forth. Mine were about 1/2 way to falling off and only held in place by a heavily buckled snubber washer - a strong deflection or braking could have ripped the arm free. Interestingly 2 MOTs and services failed to recognise this... Those parts were removed and binned, replaced by Lotus' own polybush which has a bonded inner and outer shroud and must be pressed into the upper wishbone arms with only slightly more force than just finger and thumb ! If I were doing the car again I would use Lotus only parts and know they have been correctly engineered and tested for the vehicle.
