If you own a 1990 Nissan Pathfinder, you know that keeping the front suspension in top shape is essential for off-road capability and daily driving comfort. Over time, bushings wear, ball joints loosen, and shocks lose their dampening. A front suspension kit from Geek Parts offers a comprehensive solution, bundling everything needed to restore or upgrade your Pathfinder's front end. But with several kit options available, which one should you choose? This guide breaks down the key considerations, components, and installation insights to help you make the right call.
What Does a Geek Parts 1990 Pathfinder Front Suspension Kit Include?
Geek Parts designs its kits to replace worn or aged factory components with durable aftermarket parts. A typical front suspension kit for the 1990 Pathfinder includes:
- Upper and lower control arms – often with pre-installed ball joints and bushings to save time.
- Sway bar end links – for improved roll control.
- Coil springs or spring spacers – depending on whether the kit is for stock height or a lift (common for off-road builds).
- Shocks or struts – gas-charged or monotube designs for better damping.
- Stabilizer bar bushings – to tighten up the front end.
- Hardware – bolts, nuts, and washers for a complete install.
Some kits also include tie rod ends or pitman/idler arms, but those are typically sold separately. Always verify the specific contents before purchasing.
Key Factors to Consider When Choosing a Kit
Vehicle Intended Use
The first question is how you drive your Pathfinder. If it’s a daily driver on pavement, a standard-duty kit focused on restoring factory ride quality works perfectly. For off-road adventures or lifted setups, look for heavy-duty kits with reinforced ball joints, stiffer bushings (polyurethane instead of rubber), and longer travel shocks. Geek Parts offers both categories.
Ride Height and Lift Kits
Many owners of the 1990 Pathfinder want a slight lift for larger tires or better approach angles. Geek Parts provides kits that lift the front end by 2–3 inches. These include taller coil springs and extended shocks. Be aware that any lift changes your steering geometry; you may need an alignment and possibly a drop pitman arm or adjustable cam bolts to keep the alignment within spec. Check if the kit includes hardware for that.
Material and Build Quality
Look for powder-coated control arms to resist rust, greaseable ball joints for longevity, and polyurethane bushings that outlast rubber. Geek Parts typically uses heavy-gauge steel for arms and double-welded joints. Avoid kits that use thin metal or non-greaseable components if you plan to keep the truck for years.
Compatibility and Year-Specific Fitment
The 1990 Pathfinder (WD21 body style) shares some suspension parts with the 1987–1995 models, but there are differences in sway bar diameters and shock mounting. Geek Parts explicitly lists compatibility for 1990 Pathfinder 4WD and 2WD versions. Double-check that the kit matches your drivetrain and brake configuration (some kits need to clear ABS sensors). If in doubt, contact Geek Parts with your VIN.
Installing the Geek Parts Front Suspension Kit
Tools and Preparation
Before starting, gather basic tools: jack stands, floor jack, wrenches, sockets (metric and standard), ball joint press (if arms don’t come with pre-installed joints), torque wrench, and penetrating oil for rusted bolts. The job typically takes a full weekend for a DIY mechanic; professionals can do it in 4–6 hours.
Step-by-Step Overview
- Safety first – Lift the vehicle securely on jack stands, remove front wheels.
- Remove old components – Disconnect sway bar links, brake lines (do not open the hydraulic system), and unbolt the upper and lower control arms, shocks, and springs. A spring compressor is essential for coil spring removal.
- Install new lower control arm – Usually bolts to the frame and wheel spindle. Torque to factory spec (info provided in the kit manual).
- Install upper control arm – Similar process; ensure ball joint nut is torqued correctly.
- Mount shocks and springs – For lifted kits, use the provided extended shocks. Tighten shock bolts with the vehicle’s weight on the ground if possible.
- Reconnect sway bar and install new end links and bushings.
- Bleed brakes if you opened the lines; otherwise, just do a visual check.
- Get an alignment – Essential after any front suspension work. The shop will adjust camber, caster, and toe.
Common Pitfalls
- Rust – The 1990 Pathfinder’s frame and bolts are often corroded. Soak all fasteners with penetrating oil overnight. If bolts snap, you may need to drill and tap.
- Misalignment of new parts – Some aftermarket arms have different dimensions than OEM. You might need adjustable cam bolts to get the alignment within spec. Geek Parts often includes them, but confirm.
- Torque specs – Never guess. Use a torque wrench for all suspension bolts. Loose or over-tightened bolts can lead to failure.
How Does a Geek Parts Kit Compare to Other Brands?
Geek Parts is a solid mid-range option, but you may also encounter brands like Moog, Proforged, or Rough Country. Here’s how they stack up:
- Moog – Known for OEM-quality parts, but often sold individually rather than in complete kits. Their ball joints are greaseable and durable.
- Proforged – Offers highly engineered components with forged construction. Their kits are comprehensive but more expensive.
- Rough Country – Focused on lifted suspensions; their kits include more aggressive lifts but may use lower-grade shocks.
Geek Parts sits between budget and premium. Their kits are competitively priced, include most hardware, and use polyurethane bushings that outlast rubber. However, some users report that the shocks can be a bit stiff for daily driving. If you prefer a plush ride, consider pairing the Geek Parts control arms with better shocks like Bilstein or KYB.
Final Recommendation
For a 1990 Nissan Pathfinder owner looking for a reliable front suspension overhaul without breaking the bank, the Geek Parts front suspension kit is a strong choice. It delivers good value if you want polyurethane bushings, pre-assembled arms, and all necessary hardware in one box.
Choose a standard kit if you drive mostly on-road and want to restore original handling. Choose a lifted kit if you plan to run 31- or 32-inch tires and need more ground clearance. Either way, pair the installation with a professional alignment, and consider upgrading to greaseable ball joints if the kit doesn’t include them.
If you prioritize ultimate durability and don’t mind paying more, you might opt for Proforged or a custom mix of components. But for a balanced combination of price, ease of installation, and immediate improvement, the Geek Parts kit is a practical solution for your 1990 Pathfinder’s front suspension needs.
