The Complete Guide to 1992 Saab 900 Turbo Suspension Parts

The 1992 Saab 900 Turbo is a classic front-wheel-drive sports sedan known for its distinctive styling and robust turbocharged engine. To keep it handling as designed, the suspension system needs proper attention. Whether you are restoring a low-mileage example or maintaining a daily driver, understanding the correct suspension parts is essential. This guide covers the major components, common wear items, and replacement options.

Front Suspension Components

The front suspension of the 1992 Saab 900 Turbo uses MacPherson struts with coil springs mounted on the strut assembly. Key parts include:

Strut Assemblies and Inserts

Factory struts are Sachs or Boge units. Replacements are available as complete assemblies or as inserts (cartridges). For a stock ride, Sachs are a direct fit. Aftermarket options like Bilstein B6 or B8 offer improved damping for sportier handling without being harsh. When replacing struts, always replace the strut mounts and bearings—these are common failure points that cause clunking noises and misalignment.

Coil Springs

Front springs for the 1992 900 Turbo are progressive rate designed for a comfortable ride with good control. Over time, springs sag, reducing ride height and upsetting geometry. OEM replacement springs from Lesjöfors or Kilen are budget-friendly. For lowering, Eibach Pro-Kit or H&R springs drop about 1.2-1.5 inches while maintaining proper spring rates. Avoid overly stiff springs unless matched with performance shocks.

Control Arms and Bushings

The lower control arms have a ball joint and two rubber bushings. The rear bushing wears first, leading to vague steering and tire wear. Press-in polyurethane bushings from Powerflex or SuperPro restore precise feel but transmit more road noise. Complete control arms with pre-installed ball joints and bushings make replacement easier. OEM arms are from Moog or TRW.

Sway Bar and End Links

The front sway bar (18mm diameter on most 900 Turbos) connects to the struts via end links. Over time, the rubber bushings in the end links and bar mounts crack and cause clunks. Replace with OEM-style links or heavy-duty Moog units. Upgrading to a thicker sway bar (22mm from the 900 SPG) improves flat cornering without harshness.

Rear Suspension Components

The rear suspension is a beam axle with trailing arms, coil springs, and separate shock absorbers.

Shock Absorbers

Rear shocks are separate from springs. Factory are again Sachs. Replace with Sachs for stock comfort, or Bilstein B6 for better control. KYB Gas-A-Just shocks are a mid-price option and firm up the ride. Always replace rear shock mounts (bottom bushings) when doing shocks.

Coil Springs

Rear springs wear over time. OEM replacements from Lesjöfors or Kilen are affordable. For lowering, Eibach Pro-Kit or H&R springs are matched to front springs. A slight rear sag is common; measure ride height before ordering.

Trailing Arm Bushings

The rear beam axle is located by two trailing arms per side, each with a large rubber bushing at the chassis end. Worn bushings cause vague rear tracking and bump steer. Replace with polyurethane bushings for longevity, or OEM rubber for comfort.

Steering and Alignment Parts

Tie Rod Ends and Sway Bar Links

Inner and outer tie rods wear, causing steering play. Moog or TRW are good replacements. Always replace as a pair. The front sway bar end links also affect steering feel.

Alignment Specifications

After any suspension work, align the car. Factory specs: Front camber -0.5° to 0°, caster 2.5°-3.5°, toe 0 to 1/8" total toe-in. Rear alignment is not adjustable without shims or adjustable trailing arms; if the rear beam is bent, replacement is needed.

Parts Buying Guide

OEM vs Aftermarket

For a daily driver, OEM-quality parts (Sachs, TRW, Moog) offer good longevity and cost less than dealer parts. For performance, Bilstein shocks and Eibach springs are proven upgrades. Avoid cheap no-name parts that wear quickly or don't fit correctly.

Where to Buy

Specialty Saab parts suppliers like eeuroparts.com, SaabCentral, or OG Saab carry most items. RockAuto has a wide selection of brands at competitive prices. Local auto parts stores may stock Moog or KYB.

Common Mistakes

• Replacing only shocks without springs: worn springs reduce ride height and accelerate shock wear.
• Forgetting to replace strut mounts: noisy and causes misalignment.
• Over-tightening polyurethane bushings: they need lubrication and correct torque.
• Ignoring bump stops: worn stops can damage new struts.

Installation Tips

• Use a spring compressor for strut disassembly; never remove the strut nut without compressing the spring.
• Soak bolts in penetrating oil a day before.
• Mark camber bolts before removal to get close to original alignment.
• When installing new control arms, tighten bushings with the car on the ground to prevent preload.
• After installation, get an alignment. The 900 is sensitive to toe.

Final Recommendation

For a daily driven 1992 Saab 900 Turbo, the most cost-effective suspension refresh includes Sachs struts and shocks, OEM-grade springs from Lesjöfors, Moog control arms and tie rods, and Powerflex polyurethane bushings for the front control arm rear bushings and trailing arm bushings. This combination restores like-new handling and ride quality without breaking the bank. If you want more performance on a tight budget, upgrade only the shocks to Bilstein B6 and keep the stock springs. Avoid lowering springs unless you also upgrade shocks and are prepared for a firmer ride. Always inspect and replace worn mounts and bushings together with the main components to avoid repeat labor.
