Porsche 911 Carrera 3.2 overhauled ZF steering gear
For the Porsche 911 Carrera 3.2 (1984–1989), the “original” steering gear is a manual (mechanical) rack manufactured by ZF. Unlike the 964, the 3.2 Carrera did not come with power steering, making these units simpler but highly prized for their direct road feel.
Here are the specific details regarding part numbers, overhauling, and current market options for 2026.
1. Key Part Numbers
The 3.2 Carrera uses a manual rack that is largely interchangeable with most “G-Model” 911s (1974–1989), but there are specific codes to look for:
-
Original Porsche Part #:
914.347.010.06 -
Superseded/Exchange #:
914.347.010.FX(The “X” suffix indicates a factory-remanufactured exchange part). -
ZF Manufacturer #: Often identified by the “ZF” logo cast into the center housing and serial numbers starting with
7820.
2. The Overhaul Process
Because the 3.2 rack is mechanical, an overhaul (remanufacture) focuses on precision and friction reduction rather than hydraulic seals. A professional overhaul typically includes:
-
Disassembly & Degreasing: Removing decades of old, hardened grease.
-
Internal Bushing Replacement: Replacing the plastic/nylon end bushings (a common failure point that causes “clunking”).
-
Rack Bar Polishing: Inspecting and polishing the gear teeth and the rack shaft to ensure smooth travel.
-
Thrust Piece Adjustment: Replacing or adjusting the “pressure puck” that holds the rack against the pinion to eliminate play.
-
Re-Greasing: Using high-quality lithium-based or specialized moly grease.
3. Comparison of Options (2026)
| Option | Estimated Cost | Pros/Cons |
| Professional Rebuild Service | $450 – $1,200 | Uses your original ZF housing; keeps the car “period correct.” (e.g., Elephant Racing, 914Rubber). |
| Remanufactured Exchange | $600 – $900 | Faster turnaround. Requires a “core” return of your old rack. |
| New Aftermarket (JP Dansk) | $500 – $750 | Brand new unit, no core required. Good for cars where the original rack is missing or damaged. |
| New Old Stock (NOS) ZF | $3,000+ | Extremely rare; usually only for high-end concours restorations. |
4. While You’re In There (The “Turbo Tie Rod” Upgrade)
Almost every 3.2 Carrera owner performing a steering overhaul chooses to install Turbo Tie Rods (930.347.020.00).
-
Why: Original 3.2 tie rods have a rubber isolated joint; Turbo rods use a solid metal ball joint.
-
Result: Significantly sharper steering response and better durability.
Important Installation Tip
When installing an overhauled rack, centering is critical. You must ensure the rack is perfectly centered (equal distance of the shaft protruding on both sides) before connecting the steering column U-joint. If it’s off by even one spline, your turn signals may not cancel correctly and your alignment will be difficult to set.
