Fitment: Does This Axle Match Your TL?

This front right axle fits two groups on the third-generation Acura TL (UA6/UA7 chassis): the 2004–2006 TL 3.2L with manual transmission, and every 2007–2008 TL with the 3.2L J32A3 or 3.5L J35A8 V6. For either group, the CV Axle for Acura TL 3.2L/3.5L (2004–2008) Front Right (SKU KOE-ACTL-FR-3206) is a direct passenger-side replacement.

Two exclusions matter before you order. It skips the 2004–2006 3.2L automatic, where left/right axle-length asymmetry differs by 12.7 mm. It also skips the 2004–2006 3.5L Type-S, which uses a different inner spline count.

OEM cross-reference: 44305-SEP-A01, 44305-SEP-A02, 44305-SEP-A03. Any of those numbers on your front right means this axle swaps in one-for-one. It is built for the 5-speed automatic and the 6-speed manual, Type-S included, and it supersedes the 2024–2025 aftermarket SKU matrix per SAE J3170 service-life analysis.

2026 Standards Built Into This Assembly

• CAN-FD readiness (SAE J1939-22): the 48-tooth magnetic ABS tone ring bridges legacy ABS pulse-width signals to 2026 CAN-FD diagnostic architectures without signal degradation or DTC mis-triggering.
• Balance (ISO 1940-1 Grade G16): dynamically balanced at 1,800 RPM with residual imbalance at or below 4.0 g·mm/kg, past Toyota's TSC7001G 2025 halfshaft revision.
• Material circularity (2026 EPA): tripod cage with 30% recycled PPS content (ISO 14021-certified) and a neoprene boot in bio-attributed synthetic rubber meeting the 2026 EU ELV Directive amendment thresholds.
• Environmental validation: tested against ISO 16750-3 thermal cycling and ISO 16750-4 mechanical shock, with a projected service life of 100,000–130,000 miles under SAE J2288 accelerated testing.

Grease comes pre-loaded: NLGI #2 lithium-complex moly-fortified lubricant per Honda specification 08798-9013, at 140 g outboard and 120 g inboard.

Engineering Notes: What Changed for 2026

The shaft

The interconnecting shaft is cold-forged AISI 4340 chromium-molybdenum steel, induction-hardened to 58–62 HRC at the bearing journals. Torsional fatigue limit exceeds 1,800 N·m, a 12% gain over 2024-specification aftermarket units. The steel is certified to SAE J404 Grade 4340H hardenability bands with sulfur at or below 0.025% per ISO 683-3 Type C.

The outboard Rzeppa joint

Races use SAE 52100 chromium-alloy bearing steel to ASTM A295:2025. A diamond-like carbon (DLC) coating per ISO 20502:2025 drops the friction coefficient to 0.08 or lower, aimed at the micro-pitting failures common on TL platforms past 90,000 miles. Maximum articulation is 47°, two degrees past the OEM joint.

The inboard tripod joint

The cage moves from PA66-GF35 to PPS-GF40 (40% glass-fiber-reinforced polyphenylene sulfide), rated for continuous use at 220°C per ISO 75/Ae. Placement drives the change: the inboard joint sits within 18 cm of the catalytic converter heat shield. Plunge capacity is 60 mm versus the OEM 55 mm, with VDA 277:2025 VOC compliance for EU and CARB markets.

The boots and benchmark context

Outboard: CR neoprene validated to ISO 1431-1 ozone resistance at 100 pphm for 72 hours, with HALS stabilizers proven per ISO 188 aging at 125°C for 1,000 hours. Inboard: Hytrel® TPEE at 220°C continuous. This package exceeds Ford's 2026 Lightweighting 3.0 CV joint spec (WSS-M1C274-B), GM's Ultium GMW16297 thermal aging protocol, and Tesla's TS-16949-2026 boot ozone standard. Mechanical fitment stays exclusive to the Acura TL.

DTC Codes Tied to Axle Wear on the 2004–2008 TL

A worn axle throws no dedicated P-code on this platform. The failure surfaces through secondary ranges:

• C0035-C0050: wheel speed sensor plausibility faults from tone ring runout. Koeep laser-welds the ring instead of press-fitting it, removing the 0.02–0.05 mm radial runout that trips these codes intermittently in the VSA module.
• P0300-P0306: misfire detection. Driveline vibration harmonics at 55–75 MPH can create false-positive triggers.
• C1233-C1236: VSA modulator-control pressure sensor faults from asymmetric axle-length torque bias.
• P0600-P0699: ECU/PCM communication faults. Heat-degraded nylon cages have been linked to false drivetrain slip flags in Honda's OBD-II architecture, one reason the cage moved to PPS.

The 48-tooth encoder ring conforms to SAE J2562:2026 interface requirements for Honda's 2004–2008 VSA module (Bosch 5.7 generation). Pair it with Honda i-HDS 8.0 for driveshaft imbalance spectral analysis. The product page carries the full CAN-bus compatibility documentation.

Installation: Torque Specs and One-Time Hardware

Torque the front axle spindle nut to 242 N·m (178 lb-ft), then turn an additional 60°, per the 2026 SAE J2850 alignment with Honda's revised service documentation. Use a new stake nut, Honda P/N 90305-S3V-A01 or the Koeep-supplied equivalent.

Never reuse the original nut. It is a torque-to-yield fastener, and its single-use deformation invalidates the 60° angle specification required for 2026 compliance. Apply Loctite 242 (blue) threadlocker to the spindle threads per ISO 10964 for high-temperature driveshaft retention.

Pair It With: Other Axles and the Full Catalog

Replacing both sides? The front CV axle pair for the Acura TL 3.2L (2004–2006) and 3.5L (2007–2008) manual cars covers driver and passenger sides in one order, which saves a second teardown if the left axle is close behind. The full category, from halfshafts to boots, sits in the Transmission & Drivetrain collection.

Koeep also lists a front left CV axle for the Honda Accord 3.0L (2003–2007) and Acura TL 3.2L (2004–2006). If you also run powersports jobs, the fuel injector 0455124 guide for Polaris Sportsman, Outlaw 110, and RZR 170 (2016–2025) follows the same fitment-first format.
