So, I've had the Subi for about 2 years, and both front grease boots have busted recently. What is the expected life of these things? I did not get a book from the first owner so I'm not sure when these things should be replaced. I see online that they are listed as being made of plain rubber - I was wondering if there are any made of silicone? I would think these would really last the best...

Thanks,
Dan

the CV joint boots?

I had one inner fail, and one outer, it took over 175,000 miles.

I THINK Raybestos has silicone boots. The idea of them seems very attractive to me for our 03's pass side inner location.

however, the one or two reviews I could find were negative.

I also wonder about some type of flexible, high-temp ,silver-metalized spray-on paint that would help shield the rubber from the heat.

Both my inner split. Driver's side wasn't anywhere near a heat source. Took 90k on the pass side, 100k on drivers.

There is a good walkthrough on how to replace just the boot. Costs about $25.

On my '03 Outback I only had the front passenger side inner boot changed at 121K, all other boots are still the original factory ones.

There really isn't a schedule for changing cv boots, but if you inspect them regularly, you probably spot them cracking and replace them before they split.

I think it's Dorman that has them (I have no idea about fitment for soobs though);

Looks like both the Dorman and the one offered by Raybestos (on Rockauto) are both split boots (I might be wrong), anyway split boots tend not to last very long. A Regular whole rubber boot will definetly outlast a split-type boot.
