Audi VW Mercedes Wheel Bearing Rear Outer - OEM Rein CRP-BEM0037P

Product Information

Wheel bearings support the vehicle's weight and reduce rotational friction, located within the wheel hub/spindle. European car manufacturers typically use three types of wheel bearings: unsealed, sealed press-in, and wheel bearing/hub assemblies.

Unsealed bearings, common in pre-1990 cars, require regular greasing, while sealed bearings, used from the 1990s onward, are maintenance-free and must be replaced when worn. The most modern approach integrates the wheel bearing into the hub assembly, simplifying replacement by bolting in a new unit.

Signs of failure include a grinding noise, which worsens over time. Diagnosing involves lifting the car to check for wheel play and noise. Replacement processes differ: unsealed bearings need cleaning and proper alignment, sealed bearings require pressing out, and hub assemblies are straightforward to unbolt and replace. Correct torque application is vital for all types to prevent premature failure.

• Grinding or growling: A bad wheel bearing will first reveal itself by making a growling or grinding noise when unloaded, IE if turning right, the right side will make noise. Eventually, as it gets worse, so will the sound until it’s replaced
• Play in the wheel: With the wheel off the ground, you will detect play from a worn wheel bearing. This is because the internal bearings have worn away and are no longer perfectly tight.
• Vibration or wobble: While much less frequent, if a wheel bearing is very bad or has an excessive amount of play in it, it will cause issues with the vehicle's handling, including vibration or wobble noticeably through the steering wheel.
• Uneven Tire Wear: A faulty Wheel Bearing can adversely affect tire wear and cause uneven wear across the tire contact patch.
• ABS warning light: If you are chasing an ABS issue and you have sorted out the sensors, it’s not impossible that damage has occurred to the ABS tone ring inside of the wheel bearing. If you have a single corner fault but the ABS sensor checks out, replace the wheel bearing and in turn the tone ring.

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
