Can you lube polyurethane bushings?
Polyurethane bushing manufacturers advise to never use a petroleum based grease for poly bushing lubrication. Polyurethane should only be lubricated with one specific type of grease to insure long bushing life, and squeak-free performance, Silicone based synthetic water-proof grease.
Should rubber bushings be lubricated?
Over time, control arm bushings and other rubber suspension components can deteriorate, crack and squeak. Lubricating the parts can eliminate the noise, but you must choose the lubricant wisely. Petroleum-based lubricants are NOT compatible with rubber. They will cause the rubber to swell and deteriorate quickly.
Are polyurethane bushings oil resistant?
Hardness: Polyurethane bushings are much harder than rubber ones. Lifespan: Because they’re harder, poly bushings cope a lot better with the demands of the suspension system. They’re also resistant to UV, oils, road chemicals, rust, and heat.
Do poly bushes need grease?
Silicone Based Lubricant This is the main reason many poly bushing manufacturers use a silicone base in their grease. A common additive to that base is PTFE (polytetrafluoroethylene) since it lowers friction and is completely waterproof, both things you want in a lubricant.
How do polyurethane bushings work?
Polyurethane bushings range from 75 to 95A depending on the manufacturer and position. This means poly will not deflect or bend as much as your original bushings which result in better alignment holding and stability for your suspension parts but also increase NVH (noise, vibration, harshness).
Which is better rubber or polyurethane?
In the case of tires, seals, and some belts, rubber is the best material. In the case of bushings, spacers, and high load components, polyurethane is the better choice. Polyurethane has higher abrasion, cut, and tear resistance.
Are polyurethane suspension bushings better?
Lifespan: Because they’re harder, poly bushings cope a lot better with the demands of the suspension system. They’re also resistant to UV, oils, road chemicals, rust, and heat. Often outlasting the vehicle they’re installed on, polyurethane bushings are usually covered by comprehensive warranties.
What does grease do you use for your poly bushings?
Prothane’s Super Grease is a silicone based grease with a PTFE additive which means it’s water-proof, reduces friction, and sticks to polyurethane bushings. Prothane’s Super Grease was designed specifically for their bushings, to prevent the polyurethane from squeaking. This stuff is sticky, and we mean sticky.
What do polyurethane bushings do?
Polyurethane bushings are used because polyurethane is superior to other materials such as plastic, rubber and steel. Polyurethane bushings offer high load and high compression abilities that function long after rubber and plastic bushings have failed. Client bushings are completely customized according to function.
