Transforming a classic Bentley to a rack and pinion steering system demands precise assessment and tailored modifications. Initially, ensure the current recirculating ball system's compatibility with a rack and pinion setup by evaluating the chassis and steering parts. Equip yourself with a comprehensive toolkit and a suitable steering kit, complete with mounting brackets and tie rod ends. For removal, disconnect the battery to prevent electrical mishaps, then meticulously detach the steering column components. Securely install the new rack, aligning it precisely with the column's output shaft. Post-installation, alignment adjustment is crucial for optimal performance and safety. By investigating each step, further insights can be uncovered.Assess Your Vehicle's CompatibilityIf you're thinking about switching to rack and pinion steering in a classic Bentley, start by checking if your car can handle this modern system. Classic Bentleys often use a different type of steering called recirculating ball steering.To make the change, you need to look at your car's current steering setup carefully. Several things can affect compatibility, like the car's model year, chassis design, and the condition of the steering parts.The chassis of the Bentley must be able to fit the rack and pinion system, which is usually smaller than older systems. You'll need to check the alignment of the steering column and where it mounts to make sure the new system fits well with the car's framework.Also, look at the space in the engine bay, as you might need to make some custom changes for the rack and pinion to fit.For instance, a Bentley from the 1960s might have different design issues compared to a model from the 1980s. Each model might require different solutions, possibly needing custom brackets or steering shafts.Checking these parts helps make the upgrade work well and keeps the classic Bentley's style.Gather Necessary Tools and PartsBefore upgrading your Bentley's steering system, gather all tools and parts. This step needs careful planning. A good toolkit is key. Include both general car tools and those specific to your Bentley model. Precise tools help avoid problems.Rack and Pinion Kit: Choose a kit that fits your Bentley. Kits usually come with mounting brackets, bushings, and tie rod ends.Modification Tools: Some changes may be needed due to the unique design of classic Bentleys. Use tools like a torque wrench, ball joint separator, and hydraulic jack. A torque wrench helps tighten parts to the right level.Safety Gear: Safety is a must. Wear gloves and safety glasses. Use jack stands to keep the car stable when lifted.Remove the Existing Steering SystemStart by disconnecting the car battery to avoid any electrical issues.Inside the car, find the steering column. It's held in place by fasteners connected to the dashboard and floor. Remove these fasteners to detach the steering column.You'll see it's attached to the steering box with a universal joint; carefully disconnect this joint.Now, look under the hood for the steering box. It's bolted onto the chassis. Loosen and take out these bolts to free the box.Pay attention to the steering linkage and the pitman arm, which links the steering box to the wheels. Use a puller to remove the pitman arm safely.Move on to the tie rods. These connect the steering linkage to the wheels. Use a tie rod puller to take them off without damage.Label and store each part in case you need them later. Document everything as you go. This will help if you need to reinstall or replace parts later.Install the Rack and Pinion UnitTo install the rack and pinion unit on your classic Bentley, make sure you have the right model that fits your car. Using the wrong one can cause steering problems or damage.Once you have the correct unit, follow these steps:Place the Rack and Pinion: Use a lift or jack stands to safely raise the vehicle. Position the rack and pinion unit where the old one was. This keeps the steering working properly.Attach the Mounting Brackets: Use the brackets that come with the rack and pinion. Tighten them firmly with a wrench to about 45-60 ft-lbs so they stay in place.Connect to the Steering Column: Line up the input shaft of the rack and pinion with the steering column's output shaft. Make sure they fit together well to avoid wear or steering problems.Follow these steps for a smooth installation.Connect Steering LinkagesTo get your classic Bentley's new steering system working smoothly, start by checking if the tie rods fit with the new setup. Many older Bentleys might need custom tie rod ends to fit the new rack and pinion steering. These parts should be strong, usually made from tough steel or aluminum, to handle the car's needs.First, connect the inner tie rod ends to the rack's output shafts. Make sure they fit snugly to avoid any issues like uneven tire wear.Next, attach the outer tie rod ends to the steering knuckles. Tighten the castle nuts to about 35 to 45 foot-pounds so they stay in place when driving.When picking linkages, go for adjustable ones for easier steering adjustments. Also, look into aftermarket parts like better bushings for longer-lasting performance. Brands such as Moog and Delphi are known for their durable parts.Adjust Steering AlignmentBefore driving your classic Bentley with its new steering system, make sure the steering alignment is right. Proper alignment helps your car perform well and keeps you safe.Bad alignment can wear out your tires unevenly, make handling harder, and cause an uncomfortable ride. Here's how you can adjust your car's steering alignment:1. Camber Adjustment: This is the angle of the wheels when you look at the car from the front. It affects how well your car turns corners.Adjust the wheel tilt so the top edges lean slightly inward. This helps the car grip the road better.2. Toe Setting: This is about the direction your tires point in relation to each other. You might need them to point slightly inward (toe-in) or outward (toe-out).This helps your tires wear evenly and keeps your car stable. It's a good idea to get a specialist to help with this.3. Caster Angle: This angle affects how the steering wheel returns to the center after a turn.A positive caster angle helps the car go straight more easily. This is useful for a smooth drive in your Bentley.These steps help your Bentley perform well with its classic look and new steering features.Test the New SystemOnce you have the new steering system in your classic Bentley, check it out to make sure everything works well. First, look at all the parts like the steering rack, tie rods, and brackets to see if they're tight and secure. Make sure there aren't any leaks that might mean there's a problem with the hydraulic system.Take the car for a slow drive in an open space to see how the steering feels. Notice if the steering wheel lines up correctly and goes back to the center easily after turning. The steering should feel accurate and not loose, giving a clear connection between the wheel and the road.Try different moves such as sharp turns, changing lanes, and parking to see how the system handles different situations. Listen for any odd noises like whining or grinding, as they might mean parts aren't aligned right or weren't installed properly.Check how hard it is to steer; it should be steady and not too hard. Feel the steering feedback, making sure it makes driving enjoyable without extra resistance. If anything seems off, fix it right away to keep the system safe and working well.Maintain Your Upgraded SteeringTo keep your upgraded steering system in good shape, regular care is needed. This helps your classic Bentley drive smoothly and keeps the car in top condition.Follow these steps to maintain your steering system:Check Fluid: Look at the power steering fluid often. Make sure it's clean and at the right level. Use the type of fluid recommended by the maker of your upgrade kit if you need to add more.Look for Leaks: Check the steering parts, like the rack, pinion, hoses, and connections, to see if there are any leaks. Finding leaks early helps stop fluid loss, which is important for the system to work right.Check Alignment: Keep an eye on your wheel alignment. Proper alignment ensures good steering and reduces tire wear.People Also AskHow Much Does a Rack and Pinion Conversion Typically Cost for a Bentley?Changing the steering system to a rack and pinion on a Bentley usually costs between $2,000 and $5,000.
