How to Replace the Rear Wheel Bearing on an E39 BMW 528i
Replacing Your E39 Rear Wheel Bearing Without Special Tools
Skip the dealership fees and the expensive specialty tools. Replacing the rear wheel bearing on your E39 BMW does not require a master technician's toolbox if you know the right workarounds.
The Short Answer (TL;DR)
Replacing the rear wheel bearing on a 1998 BMW 528i (E39) typically takes 3 to 5 hours per side. Instead of buying expensive BMW pullers, you can remove the entire hub carrier and use a standard hydraulic press or slide hammer. While the suspension is disassembled, upgrading your trailing arm bushings or suspension components is highly recommended.
The DIY Process Overview
Factory service manuals make this job seem impossible without proprietary BMW pullers to get the hub off the axle splines. The reality is much simpler. First, safely lift and support the rear of the vehicle, then remove the wheel, brake caliper, and rotor. Make sure to hang the caliper securely using a bungee cord to prevent brake line damage.
Next, detach the axle nut. This usually requires a heavy-duty impact wrench or a long breaker bar since it is heavily torqued from the factory. Instead of fighting the hub on the car, many driveway mechanics find it easier to unbolt the control arms and remove the entire wheel carrier assembly. Once the carrier is off the car, you can take it to a workbench and use a standard hydraulic shop press to push out the old hub and bearing.
When pressing in the new bearing, ensure you only apply pressure to the outer race to avoid destroying the new internal rollers. After the new bearing and hub are seated, reinstall the carrier assembly, torque all suspension bolts to factory specifications under load, and stake the new axle nut securely.
Why You Should Upgrade While You're In There
Since you are already pulling the rear brakes, axle nut, and potentially the hub carrier, you have full access to the rear suspension and drivetrain. This is the exact moment to address aging factory parts that are prone to failure. Upgrading your suspension components or adding a performance tune will drastically tighten up the handling and power delivery of your E39.
Recommended Upgrade: Performance ECU Tune and upgraded polyurethane suspension bushings to eliminate rear-end slop and improve throttle response under hard acceleration.
Frequently Asked Questions
How difficult is it to remove the hub from the axle splines?
If the splines are rusted, it can be extremely stubborn. Using a heavy-duty penetrating fluid a day before the job and utilizing a standard 3-jaw puller or a slide hammer will usually break it free without needing the specific BMW specialty tool.
Will a bad wheel bearing cause secondary damage?
Yes. If left unchecked, the excess heat and vibration from a failing rear bearing can score the hub, damage the CV axle splines, and ruin the wheel speed sensor. Replace it as soon as you hear the telltale rotational roaring or grinding noise.
