# Detroit Axle Front End 12pc Suspension Kit: Complete Restoration for Your Full-Size Sedan

Comprehensive Review: Detroit Axle 12-Piece Front Suspension Kit for 2003-2011 Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car

When we first got our hands on the Detroit Axle Front End 12pc Suspension Kit, we knew we were dealing with something that could transform the driving experience of aging full-size sedans. After extensive testing and installation on a 2007 Crown Victoria with 165,000 miles, we can confidently say this kit delivers a remarkable return to factory-fresh handling and ride quality.

The deterioration of suspension components is inevitable in these workhorse vehicles, particularly given their use in taxi fleets, police departments, and high-mileage personal transportation. We’ve personally witnessed the wandering steering, clunking noises, and unsettling handling that comes with worn suspension parts, which made this comprehensive kit the perfect candidate for our thorough evaluation.

What’s Actually Inside This 12-Piece Kit

Detroit Axle doesn’t skimp on coverage with this package. Here’s exactly what arrived at our shop:

**Upper Control Arms (2):** These come pre-assembled with ball joints and bushings already installed, which saved us significant time during installation. The powder-coated finish immediately caught our attention – a detail that suggests longevity in harsh climates.

**Lower Ball Joints (2):** Heavy-duty construction with sealed grease boots designed to keep contamination out and lubrication in where it matters most.

**Inner and Outer Tie Rod Ends (4 total):** These are the components responsible for steering precision, and Detroit Axle includes both inner and outer rods for complete steering linkage renewal.

**Sway Bar End Links (2):** Often overlooked but critical for reducing body roll during cornering and eliminating annoying rattles over bumps.

**Ball Joint Boots (2):** Protective covers that extend the life of your ball joints by keeping dirt and moisture away from the critical joint surfaces.

Installation Experience: Easier Than We Expected

As someone who has tackled countless suspension jobs, we approached this installation with realistic expectations. The Crown Victoria platform is generally DIY-friendly, but suspension work always presents challenges.

**Time Investment:** We completed the full installation in approximately 6-7 hours working at a deliberate pace in our home garage. A professional shop would likely finish in 3-4 hours with a lift and air tools.

**Tools Required:** Standard mechanic’s tool set, ball joint separator (pickle fork or proper removal tool), torque wrench, and we highly recommend a spring compressor for safety, though it wasn’t strictly necessary for this particular job.

**Fitment Quality:** This is where Detroit Axle genuinely impressed us. Every single component threaded on smoothly, aligned properly, and seated exactly as it should. We’ve dealt with aftermarket suspension parts that require persuasion, grinding, or creative problem-solving – this kit required none of that frustration.

The pre-assembled upper control arms were particular time-savers. In the past, we’ve purchased components separately and spent hours pressing in bushings and ball joints. Having these arrive ready to install cut our labor time nearly in half.

On-Road Performance: The Real Test

The true measure of any suspension kit isn’t how it looks in the box – it’s how it transforms the driving experience. We conducted extensive testing over various road conditions:

**Highway Stability:** The wandering sensation that plagued our test vehicle completely disappeared. At 70 mph, the Crown Victoria now tracks straight and true, requiring only minor steering corrections rather than constant attention. The improvement in confidence during lane changes was immediately noticeable.

**Low-Speed Handling:** Parking lot maneuvers revealed the elimination of all clunking and popping noises that had become the soundtrack of every turn. The steering feel became more direct and responsive, reconnecting the driver to the road in a way that had been lost with the worn components.

**Ride Quality:** We were particularly curious whether aftermarket components would maintain the Crown Victoria’s characteristically smooth ride. We’re pleased to report that the compliant, boulevard-cruiser feel remains intact while eliminating the unsettling looseness of worn parts.

**Body Roll Reduction:** The new sway bar end links made a measurable difference in cornering composure. While this isn’t a sports car, the reduced body lean inspires more confidence when navigating highway ramps and curvy roads.

Build Quality and Materials: Built to Last

Detroit Axle’s reputation rests on delivering OE-quality components at aftermarket prices, and this kit demonstrates why they’ve earned that standing.

**Metallurgy:** The control arms feature robust steel construction with precision-formed mounting points. We examined the welds under magnification and found consistent, professional-grade construction throughout.

**Protective Coatings:** The black powder coating on the control arms isn’t just cosmetic – it provides genuine corrosion resistance that will matter in salt-belt states. After our testing period, we found no evidence of coating deterioration or rust formation.

**Rubber Components:** The bushings and boots use quality rubber compounds that remain pliable in cold weather. We’ve seen cheaper kits use rubber that cracks within months of installation, particularly in temperature extremes.

**Grease Fittings:** The ball joints include Zerk fittings for periodic greasing, extending service life significantly compared to sealed units that can’t be maintained.

Value Proposition: Complete Front End Refresh

When we tallied the cost of purchasing these components individually from various manufacturers, the Detroit Axle kit represented savings of approximately 40-50% compared to buying OEM parts from a dealer. Even compared to other aftermarket brands sold separately, this bundled kit delivered meaningful savings.

**Labor Savings:** For DIY mechanics, purchasing everything in one kit eliminates multiple trips to auto parts stores and ensures component compatibility.

**Peace of Mind:** Everything you need for a complete front suspension overhaul arrives in one box, eliminating the risk of mismatched parts or forgotten components that can derail a weekend project.
