Subaru Forester Maintenance: Keeping Your Boxer Engine and Suspension in Top Shape
If you drive a Subaru Forester in Kenya—whether it’s the classic SG5, the rugged SH5, or the modern SJ—you know it’s more than just a car. It’s a lifestyle. With its Symmetrical All-Wheel Drive and the iconic growl of the Boxer engine, the Forester is built to handle everything from Nairobi’s traffic to the sandy tracks of Magadi.
However, a Subaru is a precision-engineered machine. Unlike a basic utility car, it does not tolerate “Jua Kali” maintenance or poor-quality parts. At Taleon Spares Kenya, we specialize in the specific components that keep Foresters performing at their peak.
In this guide, we’ll cover the two pillars of Forester health: maintaining that unique Boxer engine and solving the common “sagging rear” suspension issues.
1. The Heart of the Beast: The Boxer Engine
The Forester’s engine is “horizontal,” meaning the pistons move side-to-side rather than up and down. This gives you a lower center of gravity and better handling, but it also means gravity works differently on your engine oil.
The Oil Consumption Rule
Because the cylinders are horizontal, oil can pool at the bottom. Subaru engines are known to “consume” a little oil between services.
- The Maintenance Tip: Check your oil dipstick every two weeks. If you notice a drop, top it up with high-quality 5W-30 or 0W-20 fully synthetic oil. Never let a Subaru run low on oil; it’s the quickest way to ruin the crankshaft bearings.
Cooling is Life
The Boxer engine is sensitive to heat. If your radiator is clogged or your fan fails, the head gaskets are the first to go.
- The Taleon Tip: Inspect your radiator for “sweating” at the plastic tanks. We stock Ex-Japan Radiators and high-pressure caps to ensure your cooling system can handle a climb up the Limuru escarpment without breaking a sweat.
2. Solving the “Saggy Rear” Suspension
If your Forester looks like it’s “sitting on its tail” even when empty, you aren’t alone. Many Foresters (especially the SH and SJ models) came from Japan with Self-Leveling Shocks (SLS). These are great when new, but once they fail, they are incredibly expensive to replace with the same “original” units.
The Conversion Solution
At Taleon Spares Kenya, we provide the most popular fix for Kenyan Subaru owners: The SLS Delete.
Instead of buying one expensive self-leveling shock, we provide a kit consisting of:
- Standard KYB Excel-G Shocks: Reliable and much more affordable.
- Heavy-Duty Coil Springs: To compensate for the loss of the self-leveling feature.
This setup restores your ride height permanently and ensures your car doesn’t “bottom out” when you’re loaded for a road trip to Nanyuki.
3. The “Subie Humming” (Wheel Bearings)
Foresters are notorious for eating wheel bearings, especially if you have upgraded to larger, heavier off-road tires.
- The Sound: A low-pitched drone that gets louder as you speed up.
- The Fix: We stock Genuine Ex-Japan Hub Assemblies and NSK/NTN Bearings. Always ensure your mechanic uses a proper press to install these; hammering them in will shorten their life to just a few weeks.
4. Transmission & AWD Care
The Symmetrical AWD system requires all four tires to be the same size and have similar tread wear. If you drive with one “donut” spare or mismatched tires for too long, you will damage the center differential.
- Maintenance: Change your Gearbox/Differential oil every 40,000km to keep the AWD transfer smooth.
Summary: The Forester “Must-Have” Spares List
| Component | Why it matters | Taleon Spares Recommendation |
| Air Filter | Boxer engines need high airflow. | Use Teson or Genuine Subaru filters. |
| Spark Plugs | Hard to reach; need long life. | NGK Iridium (replace every 60k-100k km). |
| Rear Shocks | Prevents the “sinking” look. | KYB + HD Coil Spring Conversion. |
| Stabilizer Bushings | Stops the “clunking” on rough roads. | High-density rubber bushings. |
Conclusion: Keep the Adventure Going
A well-maintained Subaru Forester is one of the most capable vehicles on Kenyan roads. By staying ahead of its unique needs—especially its suspension and oil levels—you ensure that your Subie remains a reliable partner for years to come.
