How to properly replace the Rack and Pinion Boot on the BMW Z4?

Take off the tie-rod end and the screws, then you will have to remove the engine splash shield. Observe the correct installation position of the boot on the tie-rod, when it is possible to release the retaining clip(s) and slide the boot off the rack and pinion and tie-rod end. Thoroughly remove rust, rough, sharp surfaces on the tie-rod and rack and pinion housing surfaces where the new boot's sealing lips will have to fit on by polishing these with the fine abrasive paper. All grease must be removed from the old boot but the same boot should then be applied to the tie-rod inner ball joint with fresh grease if any doubt prevails over its contamination. Carefully place on the tie-rod end the new boot and place it on the rack and pinion housing in the position noted above with the outer edge of the boot. Check that the boot is not twisted and then use a flat blade to raise up the outer sealing lip so that air pressure in the boot is even and then snap the new retaining clip into place. Lastly, replace the tie-rod ball joint that was previously removed to allow the tapping process to be done.

BMW Z4 Rack and Pinion Boot

The BMW Z4 Rack and Pinion Boot protects the steering rack from road grit and moisture and keeps the sports car's steering smooth and responsive. Fitted at each end of the rack tube, the Rack and Pinion Boot seals the inside of the tie-rod joints and blocks out debris that could grind away the gears or ruin the fluid seals that contain high-pressure power steering oil. In early versions of the Z4 with hydraulic assist, this Rack and Pinion Boot prevents contamination that could get to the area of the piston where pressurized fluid pushes the rack to the left or right. Later Z4 models adopting electric assist still use the same protective Rack and Pinion Boot, despite the fact that an electric motor is applied to replace the pump and hoses, as dirt inside the gears would still cause slack or wandering. While the basic rubber bellows style stays the same, there are slight differences in length and clamp design of boots to fit different steering assemblies applied in the BMW range and specific Z4 years. Replacing a torn Rack and Pinion Boot promptly prevents expensive damage to the rack, seals, and tie-rods to ensure that the precise BMW steering feel required by true BMW enthusiasts is maintained.
