Lexus Is300 Drive Shaft Center Supports

Lexus Is300 Drive shaft center supports

Drive shaft center support bearings for your Lexus Is300 start at $24.95. We stock 4 options from Westar and Timken. This pressed bearing and rubber mount holds the two-piece driveshaft at its midpoint, allowing smooth rotation under load. When the rubber deteriorates or the bearing seizes, vibration and driveline noise follow — and left unchecked, the driveshaft itself can fail.

Signs your Lexus Is300 needs a new drive shaft center support bearing

  • A rhythmic thudding or clunking felt through the floor that increases with vehicle speed, not engine RPM
  • Noticeable vibration in the cabin — especially between 30 and 55 mph — that smooths out at higher or lower speeds
  • A squealing or squeaking noise from underneath the vehicle during acceleration or deceleration
  • Visible sagging, cracking, or complete collapse of the rubber isolator around the bearing when inspected from underneath
  • Grease splattered inside the driveshaft tunnel or on surrounding components, indicating a failed bearing seal
  • Driveline shudder or shaking on initial takeoff that lessens once the vehicle reaches cruising speed

Which drive shaft center support bearing should you buy for your Lexus Is300?

The main decision is whether you need the complete assembly — bearing, rubber isolator, and bracket — or just the bearing itself. Position matters too: some Is300 applications use a single center support, while others use front and rear supports on a three-piece driveshaft. Match the part to your driveshaft configuration before ordering.

OEM-equivalent complete assembly
Best for
Drivers who want a direct bolt-on replacement with no press work
What you get
Pre-assembled bearing, rubber isolator, and stamped steel bracket — installs exactly like the original
Bearing-only replacement
Best for
Shops or experienced DIYers with a hydraulic press who want to save cost
What you get
Just the sealed ball bearing; requires pressing out the old bearing and pressing in the new one
Heavy-duty / polyurethane isolator upgrade
Best for
Towing, hauling, or performance applications where the stock rubber wears quickly
What you get
Stiffer isolator material reduces deflection under load; may transmit slightly more NVH to the cabin
Front center support (forward position)
Best for
Vehicles with a three-piece driveshaft where the front joint is the failure point
What you get
Sized and bracketed for the forward driveshaft segment — not interchangeable with the rear position

Replacing a drive shaft center support bearing on a Lexus Is300

Moderate⏱ 1–2 hoursFloor jack and jack standsSocket set and combination wrenchesPry bar or driveshaft alignment toolTorque wrenchMarker or paint pen for driveshaft phasing marks

Before unbolting anything, mark the driveshaft at each flange with a paint pen so it goes back in the same rotational phase — reversing it causes vibration. With the driveshaft lowered, unbolt the center support bracket from the body or crossmember, swap the assembly, and reinstall with the driveshaft phasing marks aligned. Torque all fasteners to specification and road-test for vibration before considering the job complete.

Frequently asked questions

How much does it cost to replace drive shaft center support bearings on a Lexus Is300?
Parts start at $24.95 for a Lexus Is300 center support bearing assembly. A shop will typically add one to two hours of labor on top of that. Total out-of-pocket cost varies by region and whether the surrounding U-joints are replaced at the same time, which is commonly recommended.
Can I drive my Lexus Is300 with a bad drive shaft center support bearing?
Short distances are possible, but it is not advisable. A failing center support bearing allows the driveshaft to flex out of alignment, accelerating wear on U-joints and the driveshaft itself. In severe cases the driveshaft can drop completely, creating a serious road hazard. Address it promptly once symptoms appear.
How long does a drive shaft center support bearing last on a Lexus Is300?
Service life varies widely — typically anywhere from 60,000 to over 150,000 miles — depending on road conditions, towing frequency, and whether the bearing is properly shielded from water and debris. Off-road use or frequent trailer towing will shorten the lifespan considerably compared to normal highway driving.
Is replacing a drive shaft center support bearing on a Lexus Is300 a DIY job?
A complete assembly replacement is a moderate DIY job — the driveshaft must be unbolted, the center bearing bracket unbolted from the body or crossmember, and the assembly swapped. A bearing-only swap requires a hydraulic or arbor press and is better suited to a shop. Allow one to two hours for the full job.
Do I need to replace the U-joints at the same time as the center support bearing on my Lexus Is300?
It is strongly recommended. With the driveshaft already removed, U-joint replacement adds minimal extra labor. A worn center support bearing often accelerates U-joint wear due to misalignment, so inspecting and replacing them together prevents a repeat job in the near future and ensures the entire driveline is restored to proper condition.
How do I know if my Lexus Is300 has one or two drive shaft center support bearings?
Count the driveshaft segments from underneath the vehicle. A two-piece driveshaft uses one center support bearing; a three-piece driveshaft uses two — one forward and one rear. Your Lexus Is300 parts listing will specify the position. Ordering the wrong position results in a bracket that does not align with the body mount points.
