Polybush L405 User manual

  • Hello! I'm a chat assistant and I've reviewed the provided fitting instructions for Polybush products 1DQ, 1DR, and 1DS, designed for Range Rover, Range Rover Sport, and Land Rover Discovery vehicles. This document details steps on how to fit wishbone bushes and arm inner bushes correctly, including information about washer placement, lubrication, and proper tightening procedures. Do you have any questions about the fitting process or the products?
  • What lubricant is recommended for installing Polybushes?
    Where should the steel washer be placed when fitting the upper wishbone bushes?
    When should the control arms be tightened after refitting?

1DQ/1DR/1DS – Additional Fitting Instructions
Range Rover & Sport (L405 & L494) + Land Rover Discovery V (L462)
1DQ (L405) / 1DR (L494 Sport/L462 Disco V) Front Upper Wishbone Bushes:
Note: Polybushes should be fitted to both upper suspension arms on both sides of the
vehicle.
• The control arms must be correctly supported and the new 1DQ (L405) or 1DR (L494
Sport L462 Disco V) Polybushes pressed into the arm housings with strict reference to the
diagram above (The steel washer MUST be on the outside of the eye section).
• The polyurethane bush should be inserted first followed by the metal tube.
• A lubricant that can dry up very quickly such as tyre soap or washing up liquid will be more
than sufficient in assisting with installing your new Polybushes.
• Refit the control arms to the vehicle taking special care to tightening the bolts back up with
the arms held at 90 degrees which will allow for maximum camber offset.
