Steering and Suspension Overhaul


The steering and suspension components on any car are one of the most critical parts, the condition of these items dictate literally everything about the car is going to handle, and more than that it's a safety issue if any of these parts are worn out. After every season you should always inspect each component to make sure its still in good shape.
Cusco A-arm & Tein coil-over
While tearing apart my car, I found a good portion of the suspension parts to be covered in dirt so bad that I couldn't even tell the condition really. After just one season the Cusco rear A-arms were looking rough, paint missing, rust, and very filthy. The Tein coil-overs were also quite dirty, but as far as I could tell, were still in otherwise great shape. No leaks, or knocks or squeaks, so these would need only a cleaning and greasing.

On to the front end, the Cusco tension rods were also looking a little sore, covered in dirt and grime. Pretty much everything up front though was in the same condition, still totally functional but very dirty. There was dirt in the threads, and on all the adjustment parts.
AMS upper table


The AMS upper tables were the same way, they held up really well compared to everything else, but still were going to need some attention.


The lower tables are still the standard OEM Nissan items, with a ball joint on either end, these bolted to the spindle, the chassis and were braced with the tension rods. Since everything else down there was going to be cleaned up, it's not going to hurt to clean these up at the same time.

So, I started by cleaning everything with soap and warm water, I find actually dish soap works best for removing dirt and grease, and isn't harsh on sensitive components. Just be careful not to allow any soap into the bearings, as the soap will break down the lubricants and cause bearings to seize over time.


Inspection...
With everything clean and dirt free, you can now inspect each component. Check rubber boots around ball joints and tie rod ends for wear, any cracks or tears will mean they need to be replaced, as they will eventually fall apart completely, the grease will leak out and make a big mess. If you drive with worn ball joints or tie rods, it's likely that the handling of the car will be greatly compromised, and worse than that is the risk of an accident as a result of a ball joint or tie rod letting go at any speed really. For parts that have bearings, you're looking to see if the bearing rotates freely, there should be no grinding noises, or roughness in rotation.
Ready for paint


With all the components in good order I lined it all up for paint. I would give everything a base coat of POR-15 black to prevent any further corrosion, and then a top coat of metal flake red, follow by a clear coat to protect the red paint from rocks and road debris.


In order to give my wheels a wider stance, which will help with stability at high speed, I'd ordered up a set of +20 mm spacers for the front and rears. Since these too are all part of steering and suspension, I tossed these in for paint as well.


Coil-overs and tables (cleaned)
For the coil-overs and the upper tables, rather than repaint them I decided to just leave them in their original finish, but to protect them I greased everything up, and covered all the threads in anti-seize, so that after the upcoming season they would still be in good shape and I wouldn't need to worry about them again.

Everything turned out really nice, below are pictures of each part finished.
