TL4 Gearbox Input Shaft Bearing | Renault Clio 3 RS

The critical damage caused by a worn TL4 gearbox bearing: what your Clio 3 RS loses

The high-revving, naturally aspirated F4R engine of your Renault Sport hot hatch demands lightning-fast shifts and subjects the manual TL4 6-speed gearbox to massive rotational stress. Keeping a worn, high-mileage, or fatigued shaft support instead of installing the premium roulement arbre primaire côté 6ème boite TL4 Clio 3 RS directly compromises your entire geartrain. Under hard acceleration and high-rpm gear engagements, a failing bearing creates harmful axial movement. You lose the millimeter-perfect alignment between the teeth of the input shaft and the output shaft. This leads to difficult engagement of 5th and 6th gears, heavy metal shaving accumulation in your gear oil, and a loud mechanical howling noise. Ignoring this warning sound eventually causes the bearing cage to disintegrate, locking up the gears instantly and cracking the transaxle casing on your performance car.

This genuine-spec replacement bearing features advanced heat treatment to handle extreme radial loads and continuous high-temperature friction over long track sessions, matching the exact factory preload tolerances.

High-precision internal engineering to optimize manual transaxle endurance

Unlike standard low-cost industrial bearings that fail under competitive track conditions, this uprated automotive bearing is built to withstand high centrifugal forces. Its heavy-duty construction maintains strict shaft stability, which minimizes harmonic vibrations and guarantees crisp gear shifts. It represents an absolute necessity for the high-end maintenance of your transmission links or when hardening the mechanical parameters of your track-day sports chassis.

Drivetrain application and vehicle model compatibility guide

This genuine-spec input shaft end bearing is engineered specifically for the 6-speed manual TL4 transmission mounted on the following platform:

• Renault Clio 3 RS 2.0 16V (197bhp / 200bhp) – Fits all Phase 1 and Phase 2 models, including F1 Team R27, Cup, Luxe, and Gordini editions utilizing the F4R830 or F4R832 engine variants (Years 2006 to 2012).

Frequently Asked Questions regarding TL4 input shaft bearings (FAQ)

What are the main symptoms of a failing input shaft bearing?
The most common symptom is a noticeable whining or whirring noise that increases with engine speed while the clutch is engaged (pedal up). The noise typically disappears or significantly decreases when you press the clutch pedal down, indicating the bearing is losing its structural rolling integrity.

Does the installation of this bearing require a full transmission teardown?
Yes. Replacing the 6th gear side input shaft bearing requires removing the TL4 gearbox from the vehicle and splitting the transmission cases. This allows the shaft assemblies to be removed safely on a clean bench to press off the old bearing and set up the proper casing shims.

Restore your gearbox alignment and eliminate drivetrain vibration

A loose or damaged shaft bearing alters the mechanical gear mesh, risking catastrophic metal contamination across your entire transmission. Do not let an unusual noise lead to a cracked carter and a complete gearbox replacement costing thousands. Trust the premium geartrain hardware curated by the Optimiz Access team to protect your drivetrain, and finalize your order for the Input Shaft Bearing Clio 3 RS TL4 today.
