Replacing worn-out bushings in your car’s suspension is crucial for maintaining handling and stability. While specialized press tools are recommended, this guide demonstrates how to replace rear suspension bushings on a BMW E90 using readily available tools and some ingenuity. This process can be applied to other car models with slight modifications.
Adapting Common Tools for Bushing Removal
The BavAuto/ECS Tuning bushing tool set, while not specifically designed for the E90, provided a foundation for this DIY project. Combined with components from Home Depot and Autozone, a functional press setup was created. It’s important to note that the ECS Tuning fitment guide incorrectly lists compatibility with all 3-series models, and should be updated.
Inner and Outer Trailing Arm Bushings
For both inner and outer trailing arm bushings, a 1.5” PVC pipe served as the receiving tube. A Duralast 1-5/16” socket, after some grinding to fit the bushing opening, was used to push out the old bushings. Grade 8 washers provided additional support during the process. Accessing the inner bushings proved challenging, requiring removal of the exhaust mid-section and front subframe bracket. The fuel tank’s proximity necessitates extreme caution when pressing out this bushing.
Wheel Carrier Ball Joint
The same PVC and socket combination effectively removed the outer wheel carrier ball joint. With 130,000 miles on the vehicle, significant play in the ball joint warranted replacement. Refreshing this bushing is highly recommended for maintaining rear-end stability, especially under load.
Lower Control Arm Bushing (Inner)
The lower control arm bushing required a larger 2” PVC receiving tube and a Duralast 1-7/16” socket (no modification needed). Several washers aided in the removal process. This bushing presented the most difficulty due to the lack of a solid anchoring point for the receiving tube. The process was noisy and slow, requiring patience.
Results and Future Updates
After replacing the bushings and ball joint with Whiteline performance components, the rear suspension felt significantly more solid and stable. Even before a wheel alignment, a noticeable improvement in handling was evident, surpassing the positive effects of previously installed Whiteline subframe bushings. A follow-up report will be provided after alignment and new tire installation.
This DIY approach demonstrates that with resourcefulness, common tools can be adapted for Press Tools Bushing Car repair projects. However, always prioritize safety and exercise caution when working on your vehicle’s suspension. While this guide provides general guidance, consulting a repair manual specific to your car model is recommended.
