BMW E34 M5 WHEELS ON MY DAILYDRIFTER 525 + FIX ! Today I fix my new BMW E34 M5 wheels and put them on my car, I visit a friend of mine with BMW E46 320d. and we fixed out cars …

Below is a detailed guide on how to perform this task, with an emphasis on the tools you’ll need and the steps involved.

### Tools and Materials Needed

– **Jack and Jack Stands**:
– Use a hydraulic jack to lift the vehicle and jack stands to support it safely. Never work under a vehicle only supported by a jack.

– **Lug Wrench**:
– A cross-type or telescoping lug wrench to remove the wheel nuts.

– **Socket Set**:
– A metric socket set (including 10mm, 13mm, 17mm, and 19mm sockets) for various bolts and nuts. A ratchet and extension will make access easier.

– **Torque Wrench**:
– To ensure that all bolts are tightened to the manufacturer’s specifications.

– **Strut Spreader Tool (Optional)**:
– This tool helps to separate the strut from the steering knuckle. Some may use a hammer and a chisel, but a spreader tool is safer.

– **Pry Bar**:
– Useful for leveraging stubborn components apart without damaging them.

– **Spring Compressor**:
– Essential for safely compressing the coil spring on the strut assembly if you are replacing the strut assembly along with the mounts.

– **Wrenches**:
– Open-end and box-end wrenches, particularly in metric sizes, for nuts and bolts that are hard to reach with sockets.

– **Hammer**:
– For tapping components loose without causing damage.

– **Penetrating Oil**:
– such as WD-40 or PB Blaster, to help loosen rusted or stuck bolts.

– **New Strut Mounts**:
– Make sure you have the correct replacement mounts for the E34 model.

### Step-by-Step Procedure

– **Preparation**:
– Park on a flat surface and set the parking brake. Gather all tools and materials before starting.

– **Lift the Vehicle**:
– Loosen the lug nuts on the front wheels slightly while the car is on the ground. Use the jack to lift the front of the car and secure it with jack stands. remove the wheels.

– **Remove the Strut Assembly**:
– Locate the top strut mount bolts in the engine bay. These are usually located under a plastic cover.
– remove any covers and disconnect any electrical connectors or hoses if necessary.
– Use the appropriate socket to remove the strut mount bolts from the top.

– **Detach the Strut from the Steering Knuckle**:
– Locate the bolts securing the strut to the steering knuckle. Apply penetrating oil if they appear rusted.
– Using a socket and wrench, remove these bolts. If necessary, use a strut spreader tool or a hammer to separate the strut from the knuckle.

– **Remove the Strut Assembly**:
– Once the lower bolts are removed, carefully maneuver the strut assembly out of the wheel well. Be cautious as the coil spring is under tension.

– **Compress the Spring** (if replacing springs):
– If you are replacing the strut assembly, use the spring compressor to safely compress the coil spring. Follow the instructions carefully to avoid injury.

– **Replace the Strut Mounts**:
– With the strut assembly out, remove the old strut mounts from the top of the strut. These may be held on with nuts that require a socket or wrench to remove.
– Clean any dirt or debris from the area and inspect for any other signs of wear.

– **Install New Strut Mounts**:
– Place the new strut mount onto the strut. Make sure it is aligned properly. Use the torque wrench to tighten the nuts to the manufacturer’s specifications.

– **Reassemble the Strut**:
– If you used a spring compressor, carefully release the tension on the spring once everything is reassembled. Make sure the spring is properly seated in the strut.

– **Reinstall the Strut Assembly**:
– Position the strut back into the wheel well and line it up with the steering knuckle. Insert and tighten the bolts. Ensure everything is secured and torqued to specification.

– **Reconnect the Top Mount**:
– In the engine bay, reconnect the top strut mount bolts. Ensure they are tightened properly.

– **Reinstall the Wheels**:
– Put the wheels back on and hand-tighten the lug nuts. Lower the vehicle back to the ground and then tighten the lug nuts to the correct torque specification.

– **Final Checks**:
– Once the vehicle is on the ground, double-check all bolts and nuts to ensure they are tight. Inspect the area for any loose parts or tools left behind.

– **Test Drive**:
– Take the car for a short test drive to ensure everything is functioning correctly. Listen for any unusual noises.

### Safety Tips

– Always wear safety goggles and gloves when working on your vehicle.
– Ensure your working area is well-lit and free from any hazards.
– If you are unsure about any step, consult a professional mechanic or repair manual specific to the BMW 525i E34.

Following these steps will help ensure a successful strut mount replacement on your BMW 525i E34.
The exhaust donut gasket is a vital component in an automotive exhaust system, primarily designed to create a tight seal between exhaust pipes and components such as the catalytic converter, muffler, or exhaust manifold. Shaped like a toroidal or donut-like ring, this gasket is typically made from heat-resistant materials such as rubber, silicone, or metal composites that can withstand the extreme temperatures and pressures generated during engine operation.

One of the primary functions of the exhaust donut gasket is to prevent exhaust gases from leaking into the atmosphere. An effective seal is crucial not only for vehicle performance but also for environmental compliance, as exhaust leaks can lead to increased emissions of harmful pollutants. Furthermore, a compromised gasket can result in a decrease in engine efficiency, leading to a drop in power and fuel economy.

Over time, due to exposure to high temperatures, vibrations, and corrosive exhaust gases, exhaust donut gaskets can wear out, leading to deterioration. Symptoms of a failing gasket may include a noticeable increase in engine noise, a decrease in acceleration, or the smell of exhaust fumes within the vehicle cabin. Regular inspection and timely replacement of the exhaust donut gasket are essential for maintaining the overall health of the exhaust system and ensuring that the vehicle runs smoothly and efficiently. Proper installation is also critical, as an improperly fitted gasket can lead to leaks and further complications down the line.
