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?

Hi Sajeev,

This is the second question I’ve asked on here, and while I didn’t even follow the advice I received last time and here I am again! Last time I was asking about a sporty car, and I ended up getting a 2007 Ford Ranger, 2.3L, 5 speed, with all of 35,000 miles on it. It is a regular cab with nothing extra on it, a real throw back, manual windows, no AC, a nice basic truck with nothing to go wrong right?

Wrong.

Piston Slap: Porsche Customer Service Doesn't Stink?

Hello, can you tell me what ever happened with the Porsche IMS concern? At 18K miles, an IMS bearing failure has caused a catastrophic engine failure in my Porsche 911. My Porsche dealer (who has done all of the Porsche recommended service on the car since new) just told me that there is nothing that they or Porsche can or will do, and that it is an isolated incident. I have since been doing research online, and I find out that an IMS bearing failure is not at all a rare occurrence.

I am not a litigious person and I am not out to tarnish the Porsche name. But with a repair cost of $19k, I cannot afford to get my car fixed. I am looking to get Porsche to step up and address what would appear to be a bearing design defect.
