Rear Spring plate rubber bushings

#1 Post by Brendan Head »

I’m replacing the worn out spring plate rubber bushings on my t5 356B and am left wondering if both sides of the new rubber should be greased or just one side installed and left dry? I imagine as it all gets clamped together the outer surface gets compressed allowing only the spring plate to move so only the inside surface should be greased?

Any advice on this is greatly appreciated

The inside of both bushings should be dusted with flaked graphite.

Thanks for the speedy reply Wes,
I’ve seen a few YouTube videos of them replacing the spring plate bushings on early 911s and they mostly all used silicone grease on the outside bushing surface, any opinions of graphite flakes over a silicone rubber grease?
Appreciate your reply.

Flaked graphite is what the factory recommended. I suppose graphite powder would also work. I don't have an opinion on any other lubricant, but it would certainly have to be compatible with rubber. I know the plastic bushings use a special grease, but I don't recommend them due to the harsh ride that results.

After cleaning the surfaces, I use Red Rubber grease. Won’t harm the bushings, does not dry out. A thin coating is enough, also helps keep water away from the steel parts. Castor bean oil based product,
