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?

Piston Slap: Weather The Storm, Trooper!

Hi Sajeev,

I have recently come into possession of a 1994 Isuzu Trooper (pictured above). 158k, One owner, with good service history until 100k. After that the (affluent) previous owner basically used it as a Home Depot Hauler for 7+ years so besides oil changes and tires, not much was done. That’s fine by me as the truck cost $1600 and it is pretty great running shape.

  • James Hendricks The depreciation on the Turbo S is going to be epic!
  • VoGhost Key phrase: "The EV market has grown." Yup, EV sales are up yet again, contrary to what nearly every article on the topic has been claiming. It's almost as if the press gets 30% of ad revenues from oil companies and legacy ICE OEMs.
  • Leonard Ostrander Daniel J, you are making the assertion. It's up to you to produce the evidence.
  • VoGhost I remember all those years when the brilliant TTAC commenters told me over and over how easy it was for legacy automakers to switch to making EVs, and that Tesla was due to be crushed by them in just a few months.
  • D "smaller vehicles" - sorry, that's way too much common sense! Americans won't go along because clever marketing convinced us our egos need big@ss trucks, which give auto manufacturers the profit margin they want, and everybody feels vulnerable now unless they too have a huge vehicle. Lower speed limits could help, but no politician wants to push that losing policy. We'll just go on building more lanes and driving faster and faster behind our vehicle's tinted privacy glass.
