Piston Slap: New CV Boots? A Split Decision!

Long time no talk (I sound like a native American an Indian). (Yeah, not so much. – SM)

I have an 09 Outback with ~65k miles. I had noticed a bit of a burning smell after running it for a while and it was pretty strong after a recent trip. I thought it smelled like a belt slipping but when I popped the hood the two belts looked fine. After looking around for a minute I realized that the passenger side CV boot had torn and was dripping grease on to the cat. Checking the other side revealed that the driver’s side boot was also torn. Apparently this is a pretty common failure for scoobies. The Internet says I should be concerned if I hear a “popping” sound or the clunk associated with failing bearings. Luckily I am hearing neither. The dealer had a set price of $370 per boot for replacing the boots that the service manager somewhat disconcertingly blurted out almost before I finished describing the problem. The independent shop thought they could do both for less than $500 if the axles weren’t bad, but if they were bad then it would be another $450 per.

My question is this: Can I just get split boots from JC Whitney and pack them with grease or do I really need to have the pros fix it?

  • Dave Holzman My '08 Civic (stick, 159k on the clock) is my favorite car that I've ever owned. If I had to choose between the current Civic and Corolla, I'd test drive 'em (with stick), and see how they felt. But I'd be approaching this choice partial to the Civic. I would not want any sort of automatic transmission, or the turbo engine.
  • Merc190 I would say Civic Si all the way if it still revved to 8300 rpm with no turbo. But nowadays I would pick the Corolla because I think they have a more clear idea on their respective models identity and mission. I also believe Toyota has a higher standard for quality.
  • Dave Holzman I think we're mixing up a few things here. I won't swear to it, but I'd be damned surprised if they were putting fire retardant in the seats of any cars from the '50s, or even the '60s. I can't quite conjure up the new car smell of the '57 Chevy my parents bought on October 17th of that year... but I could do so--vividly--until the last five years or so. I loved that scent, and when I smelled it, I could see the snow on Hollis Street in Cambridge Mass, as one or the other parent got ready to drive me to nursery school, and I could remember staring up at the sky on Christmas Eve, 1957, wondering if I might see Santa Claus flying overhead in his sleigh. No, I don't think the fire retardant on the foam in the seats of 21st (and maybe late 20th) century cars has anything to do with new car smell. (That doesn't mean new car small lacked toxicity--it probably had some.)
  • ToolGuy Is this a website or a podcast with homework? You want me to answer the QOTD before I listen to the podcast? Last time I worked on one of our vehicles (2010 RAV4 2.5L L4) was this past week -- replaced the right front passenger window regulator (only problem turned out to be two loose screws, but went ahead and installed the new part), replaced a bulb in the dash, finally ordered new upper dash finishers (non-OEM) because I cracked one of them ~2 years ago.Looked at the mileage (157K) and scratched my head and proactively ordered plugs, coils, PCV valve, air filter and a spare oil filter, plus a new oil filter housing (for the weirdo cartridge-type filter). Those might go in tomorrow. Is this interesting to you? It ain't that interesting to me. 😉The more intriguing part to me, is I have noticed some 'blowby' (but is it) when the oil filler cap is removed which I don't think was there before. But of course I'm old and forgetful. Is it worth doing a compression test? Leakdown test? Perhaps if a guy were already replacing the plugs...
