FAQ

What Type Of Grease Should I Use For Polyurethane Bushings?

You should choose a grease specifically formulated to be compatible with urethane rather than a general-purpose petroleum grease. Look for silicone/PTFE blends or urethane-targeted prelubes that advertise non-damaging compatibility with plastics and rubbers, because those maintain the bushing material and prevent softening.

Also consider tackiness and washout resistance: a tacky, stay‑put formula is ideal for suspension bushings, while a silicone/PTFE all‑rounder can be a better choice if you need broader material compatibility or food‑safe registration.

How Do I Apply And Maintain Bushing Grease?

Start by cleaning contact surfaces and removing old contaminants, then apply a thin, even layer inside the bushing or on the mating surface so the lubricant forms a consistent film. Pack the grease into a small grease gun or use single‑use packets for neat doses, and avoid overfilling which can trap dirt.

During installation use wear gloves and a dedicated tool if possible to avoid transferring tacky grease to other parts. Check bushings after a few hundred miles and after heavy wet exposure; reapply as needed when you notice reduced lubrication or return of noise.

Will Grease Wash Off Or Damage My Bushings?

If you choose a urethane‑compatible, waterproof formula it will resist washout and hold up to puddles and pressure washing much better than standard greases. Proper bushing greases are designed not to attack polyurethane, but petroleum‑based products can degrade urethane over time, so do not use petroleum greases on poly bushings. Cleanup is often difficult with tacky formulas, so plan on solvent or specialized cleaners for hands and tools, and use gloves to avoid stubborn residue.

Customer Preference Trends

When choosing between Formula 5 Prelube, Prothane Packet, and Super Lube Silicone, you typically prioritize stay‑put tack and washout resistance, packaging and ease of application, and temperature and material compatibility. You’ll lean toward Formula 5 for its ultra‑tacky durability, Prothane for neat, single‑use convenience during targeted installs, and Super Lube when you need a high‑temp, broadly compatible grease that doubles as a multi‑purpose shop product.

Wrapping Up

If you want a single go-to product that balances tack, longevity, and application ease, choose the tub of Formula 5 Prelube. If your priority is small, pre-measured packets for installs and swaps, the Prothane packets deliver targeted convenience.

For broader workshop use and high-temperature resistance, Super Lube Silicone offers versatility and wide material compatibility. Pick the 3-pack of Formula 5 if you want the most economical small doses, choose Daystar Lubrathane when you need a product specifically formulated for urethane, and go with the Prothane 14 oz tube if you need bulk supply for multiple jobs. Match the product to how often you work on suspension parts and whether you prioritize convenience, temperature range, or raw staying power.
