will WD40 messed up poly urethane bushings?


Recommended Posts

i have the energy suspension bushings on the whole car, but the instructions says to grease it twice a year?? thats insane, im not goin to take off all the suspension parts 2x a year to lube em, can i just squirt em with wd40 or will that somehow deteriorate the polyurethane? tia

In a word "No" it wont hurt, but WD40 isn't a long term lube:frown: so just lube really well with Molly Grease, and you should be ok for a few years, + depending if this is your daily driver or not (how many miles per year).

I just used to spray on "Motorcycle Chain Lube" that has molly grease in it, this will penetrate into the bush, its great stuff.

I did mine over 10 years ago and just pulled the car of the road for a complete rebuild and they were still greasy!!! And was driven about 5k per year.

 

Also regular spraying WD40 would probably "wash out" the grease!:burnout:

 

The spray on Motorcycle Chain Lube works a bit like WD40, and the molly grease is carried in a solvent which allows the grease to get into the chain (bush) than the solvent evaporates leaving just the grease, its used by Moto-Crossers to keep the chains well lubed in all the dirt and mud etc

We talked about another solution to that problem on this thread here:

It involved drilling the control arm and busthing to accept zerg fittings, which would allow you to grease the bushings with a grease gun the same way you would do your ball joints or any other suspension point. It's got pics as well.

I did moto thing, enduro-offroad. After the days events after power washing and cleaning used WD to wash out the water, then chain lube, allow to dry and you are re good to go.

Interesting idea using molly chain lube on poly bushings. It makes complete sence.
