On the 2004-2006 Lexus RX, second-generation RX330 models commonly develop a clunk or knock felt through the steering column, especially at low speed over small bumps or during quick steering inputs. Lexus issued service information for intermediate steering shaft noise, and owners often describe the sensation as a loose front end despite no obvious play in major suspension joints. The condition is usually caused by wear or lash in the intermediate shaft splines or joints rather than a catastrophic steering rack failure.
Road test over small road imperfections to reproduce the column knock, then isolate the sound from the shaft, rack mounts, and front suspension links. Replacement of the intermediate steering shaft is the usual fix; some vehicles also need inspection of rack bushings and front stabilizer links if multiple noises are present. An alignment is not always required but front-end inspection should accompany the repair.

On the 2004-2006 Lexus RX 3.3L 3MZ-FE V6, rX330 owners frequently report persistent engine oil leaks that are often diagnosed at the rear main seal, timing cover area, or other lower engine sealing surfaces. The leak may start as minor seepage but can progress to oil spots on the driveway, burning oil odor, and contamination of the lower engine and subframe. Because access is labor-intensive, especially if the rear main seal is involved, repair costs can become substantial even when the leak itself is not immediately catastrophic.
Clean the engine thoroughly and use dye or UV tracing to identify the true source, since valve cover, timing cover, and rear main leaks can be misidentified. Repair involves replacing the failed seal or resealing the timing cover, often while addressing nearby components with overlapping labor. If the leak is minor, some owners monitor oil level until the leak worsens enough to justify the labor.

On the 2000-2006 Lexus RX, both RX300 and RX330 generations commonly develop power steering fluid leaks, especially from the high-pressure hose and related line connections. Owners report red fluid on the driveway, groaning or whining while turning, and heavier steering effort as fluid level drops. If ignored, the pump can run dry and fail, increasing repair cost significantly.
Inspect the pressure hose, return lines, reservoir, and pump area for wetness, then confirm whether the leak is from the crimped hose section or a fitting. Replace the leaking hose or line assembly, refill with the correct fluid, and bleed the system fully; if the pump has been noisy for long, inspect for internal damage. Cleaning the subframe and alternator area is important because leaked fluid can spread widely.

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2005-2006 AVALON, MODEL YEAR 2004-2006 HIGHLANDER, MODEL YEAR 2004-2006 LEXUS RX, AND MODEL YEAR 2006 LEXUS GS AND IS VEHICLES. BRAKE FLUID CONTAINING POLYMERS IS USED THAT ACTS AS LUBRICANTS FOR CERTAIN BRAKE SYSTEM COMPONENTS. IF REPLACEMENT BRAKE FLUID IS USED THAT DOES NOT CONTAIN SUCH POLYMERS, OR THAT CONTAINS ONLY SMALL AMOUNTS, A PART OF THE RUBBER SEAL LOCATED AT THE REAR OF THE BRAKE MASTER CYLINDER MAY BECOME DRY, AND THE SEAL MAY CURL DURING MOVEMENT OF THE PISTON. IF THIS OCCURS, A SMALL AMOUNT OF BRAKE FLUID COULD SLOWLY LEAK FROM THE SEAL INTO THE BRAKE BOOSTER.
