BMW Rear Differential Noise

The differential noise on your BMW is a typical whining noise, from the back of the car which is rather annoying on longer trips.

BMW E90 and BMW E83‘s Differentials

This is a relatively common occurrence on the BMW E90 and BMW E83 platforms. The issue at hand is the rear differentials are kind of a new design by deleting the tapered roller bearings to a multi row ball bearings to reduce frictional losses within the differential assembly.

This is a another angle to try to maximize the efficiency of the entire vehicle. Unfortunately the bearings randomly fail, due to metallic particles build up over time within the oil and having a “lifetime” oil doesn’t help.

There are no parts available to repair this noisy differentials in North America. Fortunately this is not the case in Europe, therefore we started refurbishing this noisy rear differentials by ordering the replacement parts, bearings from Europe.

Original Made in Germany Bearings for your BMW

Somehow the original bearings are not allowed to be sold in North America, BMW makes more money to sell a complete rear differential assembly, which is prohibitively expensive. We naturally do some modifications to ensure the replacement bearings will last much longer than the originals installed by the factory.

What will happen if you ignore your BMW’s differential noise?

The differential noise is the result of damaged bearings, it’s imperative to replace the damaged final drive bearings or they could cause permanent damage to the internal components.

Please note, a damaged differential may lock up inadvertently causing loss of control essentially. A locked up differential potentially a scary thing, which may cause additional damage to other components, possibly rendering the vehicle stationary unable to move anywhere.

The lost art of repair versus replacing worn components.

The complaint is on this fine 2008 X3 BMW the excessive differential noise. This is a relatively common occurrence unfortunately because the ball bearings develop a wear pattern from lack of maintenance (BMW lifetime fill). The fine metallic particles will get caught in the ball bearings and will make the bearings noisy.

Replacement Differential for BMW Cost Over $3,000

Please keep in mind, this proprietary bearings are not sold separately in North America but they’re available in Europe. A BMW replacement differential is cost over $3,000, therefore it’s more economical to repair the existing one if only requires new bearings and seals.

Used BMW differentials with low mileage are getting rare and a used differential could get noisy exhibiting the same symptom as the existing one.

BMW Differentials Repair

We fortunately found a supplier for BMW differentials replacement repair kit from the original manufacturer from Germany. This way we can reliably repair your existing rear differential assembly.

BMW Differential Assemblies

We recommend a standard service interval at 50,000 kilometers, actually it’s the same as for the BMW M model’s differentials which makes perfect sense for reliable lifelong service.

I like to point it out most of the BMW differential assemblies has no actual drain plug, ditto for the transfer case, therefore we have to use a suction machine to remove the tired old fluid.

BMW Automatic Transmission Service

We also recommend to service BMW’s transfer case and the automatic transmission at regular one hundred thousand kilometers to ensure component longevity.

The same applies to the front differential assembly, as well in the case of a four wheel drive vehicle.

Proper timely maintenance does pay back, for instance our 2006 BMW 325i has 467,000 kilometers in, under our care since 2009, it speaks volumes about proper timely maintenance.
