            FAQ - Answer 1 : No. The CV boot is housed on the axle and prevents grease from leaking out of the CV Joint. The bellows boot is housed on the steering rack and prevents dirt from getting into the steering rack and pinion system.
            FAQ - Answer 2 : No. The boot does not need to be removed, but the clamp securing the bellows to the inner tie rod shaft will need to be loosened to prevent the bellows boot from twisting when the tie rod shaft is turned to adjust the vehicle toe in or toe out specs.
            FAQ - Question 1 : Are a CV boot and Rack and Pinion Bellows the same part?
            FAQ - Question 2 : Does the bellows boot need to be removed in order to turn the inner tie rod during an alignment procedure?

            Good Maintenance Practices - Section 1 - Bullet 1 : Inspect or have your bellows inspected for signs of wear. Exposure to harsh conditions such as uneven terrain, severe weather, or large temperature changes can all take their toll on the integrity of your rack and pinion bellows, causing wear and even failure. As your bellows wear, your vehicle's steering system is exposed to water and other contaminants from the road, leading to water and dirt accumulation and degradation of the system.
            Good Maintenance Practices - Section 1 - Bullet 2 : Inspect your rack and pinion bellows to help detect wear before it becomes a major problem.
            Good Maintenance Practices - Section 1 - Bullet 3 : Installing new steering rack bellows can interfere with the alignment of your vehicle. Perform a full four-wheel vehicle alignment after any rack and pinion bellow replacement.

          Warranty Overview

          At Newparts, we stand behind the quality of the products we sell. Every part we offer is backed by a warranty designed to give you peace of mind and protect your investment.

          Standard Warranty – Most Parts

          • Coverage: 2 years or 24,000 miles (whichever comes first) from purchase date.

          • Protection: Defects in materials or workmanship under normal personal use.

          • Eligibility: Applies only to the original purchaser and the vehicle where the part was first installed.

          • Exclusions:

            • Wear-and-tear items (brake pads, filters, bulbs, wipers, etc.)

            • Commercial, fleet, rideshare, off-road, or racing use

            • Improper installation, misuse, accidents, or modifications

          • Not Covered: Labor, shipping, towing, or incidental costs.

          Bison Performance Warranty – Our House Brand

          • Coverage: Limited Lifetime Warranty for as long as you own your vehicle.

          • Applies To: All products sold under the Bison Performance label.

          • Premium Protection: Goes beyond our standard warranty — if it’s a Bison product, the 2-year/24k mile limit is replaced with lifetime coverage.

          • Exclusions: Same as the standard warranty (normal wear, commercial use, improper installation, etc.).

          • What’s Included: Replacement of the defective product (labor and shipping excluded).

          Warranty Claim Requirements

          To keep claims fast and fair, we require:

          • Proof of purchase (invoice or order confirmation).

          • Photos or videos showing the defective part, order number, date, VIN, and odometer reading.

          • Diagnostic reports or part returns for non-visible issues may be requested.

          • Claims must be truthful, properly documented, and reflect normal consumer use.

          Buy With Confidence: We back our products because we believe in their quality, with a transparent, customer-first warranty process you can trust. And with Bison Performance products, you’ll enjoy Limited Lifetime protection—an assurance few brands can match.

          For full details and exclusions, please see our complete Warranty Terms & Conditions.
