Subaru STI: Rear Subframe Bushing Deterioration (GE/GH/GR/GV WRX and STI)
Rear Subframe Bushing Deterioration (GE/GH/GR/GV WRX and STI) is a common suspension fault on the Subaru STI on the 2007–2014 cars, and we rate it major. Putting it right costs $500 to $1,300 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 32 documented faults on the Subaru STI.

What goes wrong
The GE/GH/GR/GV generation WRX and STI uses rubber rear subframe bushings that degrade with age and aggressive use, allowing the subframe to shift position under cornering and braking loads. This produces progressive looseness in rear-end handling, abnormal tyre wear, and knocking noises over sharp bumps. Deterioration is accelerated by track use, sustained hard driving, and New Zealand road surface conditions. Subframe removal is typically required for bushing replacement. At the age range this generation now represents, deteriorated bushings are widely reported across both Australian and NZ WRX communities as a common pre-purchase finding.
What you would notice
- Knocking or clunking from the rear over sharp bumps or dips
- Vague or unpredictable rear-end response under cornering load
- Uneven or accelerated rear tyre wear
- Rear wheel alignment that cannot be set correctly or does not hold
How to check it
Where to look. Rear subframe mounting bushings, four corners of the rear subframe
Visually inspect the rubber bushing condition for cracking, splitting, or collapse around the subframe mounting points. Check rear tyre wear patterns for abnormality consistent with alignment shift. If a workshop inspection is possible: With the car on a hoist, grip the rear subframe and attempt to move it side to side and front to back — any perceptible movement indicates bushing wear.
What it costs to put right
$500 to $1,300 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the rear subframe or suspension been inspected or replaced recently?”
- “Has the car been used on a track or driven hard on rough or unsealed roads?”
- “When was the rear wheel alignment last checked?”

Subaru STI buyer questions
Is rear subframe bushing deterioration (ge/gh/gr/gv wrx and sti) serious on a Subaru STI?
We rate it major and common on the Subaru STI. The GE/GH/GR/GV generation WRX and STI uses rubber rear subframe bushings that degrade with age and aggressive use, allowing the subframe to shift position under cornering and braking loads. This produces progressive looseness in rear-end handling, abnormal tyre wear, and knocking noises over sharp bumps. Deterioration is accelerated by track use, sustained hard driving, and New Zealand road surface conditions. Subframe removal is typically required for bushing replacement. At the age range this generation now represents, deteriorated bushings are widely reported across both Australian and NZ WRX communities as a common pre-purchase finding.
How much does it cost to fix on a Subaru STI?
$500 to $1,300 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Subaru STI years are affected?
Our research records this fault on the 2007–2014 Subaru STI. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
How do I check for it before I buy?
Visually inspect the rubber bushing condition for cracking, splitting, or collapse around the subframe mounting points. Check rear tyre wear patterns for abnormality consistent with alignment shift. If a workshop inspection is possible: With the car on a hoist, grip the rear subframe and attempt to move it side to side and front to back — any perceptible movement indicates bushing wear.
