What lube to use for rubber bushings, hangers and cv boots?

[ddicosmo]

I'm replacing all the fluids (ie, diff, transfer, etc.) and lubing the propeller shaft on my 2008 T4R. While I'm under there, I was wondering if I should go ahead and spray some silicone lubricant on all the rubber parts (ie. all suspension bushings, CV boots, rubber hangers for the muffler, etc.). I picked up a can of the WD40 brand Silicone spray. Is this good to use on those rubber parts? I'm hearing conflicting reports about silicone spray and whether to even spray the rubber parts. Does anyone know what Toyota recommends? Is lubing the rubber components even required? Thanks,

Dave.

I use whatever grease I have on hand when install rubber bushings, etc, but I don't lube them as maintenance.

Don't spray anything under there. It wont last long and WILL attract dirt and road grime. Imagine gravel stock to oiled or siliconed CV boot creases .

The only silicone spray that is ok to use on rubber is food grade silicone. The other silicone will look good but drys our rubber over time. I have this info becasue I'm into vintage rc cars and restoring old rubber rc car tires.

But you probally don't need to spray anything on the rubber to begin with but I can get a little OCD about my truck so who am I to judge.
