Piston Slap: What's so Hellabad About Hellaflush?

Hello Sajeev,

I had a coworker who had an older Acura NSX that was lowered. He complained about having to buy new tires because they were worn on the inside edge (down to the belts!). He had, what I thought to be, extreme negative camber due to an improper lowering. He said it was supposed to be like that. I have seen other cars running the negative camber and I’ve seen cars that were lowered without. So question, is there a reason to run extreme negative camber or is this just a bad lowering job?

Piston Slap: Spicy…or Spicier?

Wasup, Sajeev!

I have an 06 R/T Charger and I am contemplating getting a set of Eibach springs for it. What other costs might be associated aside from installation? What other products would I need to purchase, if any?

Thanks for any input,
John

Piston Slap: To What End Unibody Repair?

Matt writes:

Hi Sajeev, Long-time listener, first-time caller. I have a 2011 Volvo C30 that was recently rear-ended pretty good. As a result of the collision, the car has just had $8k+ of work done in a body shop. Included in the list of work done (among the obvious paint, bumper cover, tailgate, etc) is 4 hours of labor for a “unibody pull”. Like everyone else, I know people who have horror stories about cars that have never been the same again after accidents. I’ve only had the car back for a couple of days and everything feels ok so far, but I do fear lingering issues.

What are your thoughts on a repair like this making the car 100% again? Would you dump it immediately to avoid any potential issues or hold on to it and see?

Piston Slap: Better Steering Without the Better Car?

Sajeev,

In December of 2011, through an unfortunate chain of events, I became the not-so-proud owner of a 2007 Malibu. True to its origin as an ex-fleet car, it is saddled with the miserly 4-banger engine rather than the still-slow-but-adequate V6. The only positive attributes of this car are its cheap cost to own and excellent fuel economy for its size. It presently has about 80,000 miles on it – I expect to get another 40K out of it before the transmission implodes (domestic automatic – you get what you pay for).

Piston Slap: The Cupped Tire Quandary

Mark in Upper Kentucky writes:

Sajeev,

Here’s a tire question for you to chew on: I just bought a new Mustang V6 (w/ the performance package), so I’ll soon put my ’07 Focus ST on the block. The car is in good shape mechanically and cosmetically, but I’ve got a bit of a tire issue. The Goodyear Eagle GT on the left rear has about 30k miles on it and is making a racket.

  • Jalop1991 In a manner similar to PHEV being the correct answer, I declare RPVs to be the correct answer here.We're doing it with certain aircraft; why not with cars on the ground, using hardware and tools like Telsa's "FSD" or GM's "SuperCruise" as the base?Take the local Uber driver out of the car, and put him in a professional centralized environment from where he drives me around. The system and the individual car can have awareness as well as gates, but he's responsible for the driving.Put the tech into my car, and let me buy it as needed. I need someone else to drive me home; hit the button and voila, I've hired a driver for the moment. I don't want to drive 11 hours to my vacation spot; hire the remote pilot for that. When I get there, I have my car and he's still at his normal location, piloting cars for other people.The system would allow for driver rest period, like what's required for truckers, so I might end up with multiple people driving me to the coast. I don't care. And they don't have to be physically with me, therefore they can be way cheaper.Charge taxi-type per-mile rates. For long drives, offer per-trip rates. Offer subscriptions, including miles/hours. Whatever.(And for grins, dress the remote pilots all as Johnnie.)Start this out with big rigs. Take the trucker away from the long haul driving, and let him be there for emergencies and the short haul parts of the trip.And in a manner similar to PHEVs being discredited, I fully expect to be razzed for this brilliant idea (not unlike how Alan Kay wasn't recognized until many many years later for his Dynabook vision).
  • B-BodyBuick84 Not afraid of AV's as I highly doubt they will ever be %100 viable for our roads. Stop-and-go downtown city or rush hour highway traffic? I can see that, but otherwise there's simply too many variables. Bad weather conditions, faded road lines or markings, reflective surfaces with glare, etc. There's also the issue of cultural norms. About a decade ago there was actually an online test called 'The Morality Machine' one could do online where you were in control of an AV and choose what action to take when a crash was inevitable. I think something like 2.5 million people across the world participated? For example, do you hit and most likely kill the elderly couple strolling across the crosswalk or crash the vehicle into a cement barrier and almost certainly cause the death of the vehicle occupants? What if it's a parent and child? In N. America 98% of people choose to hit the elderly couple and save themselves while in Asia, the exact opposite happened where 98% choose to hit the parent and child. Why? Cultural differences. Asia puts a lot of emphasis on respecting their elderly while N. America has a culture of 'save/ protect the children'. Are these AV's going to respect that culture? Is a VW Jetta or Buick Envision AV going to have different programming depending on whether it's sold in Canada or Taiwan? how's that going to effect legislation and legal battles when a crash inevitibly does happen? These are the true barriers to mass AV adoption, and in the 10 years since that test came out, there has been zero answers or progress on this matter. So no, I'm not afraid of AV's simply because with the exception of a few specific situations, most avenues are going to prove to be a dead-end for automakers.
  • Mike Bradley Autonomous cars were developed in Silicon Valley. For new products there, the standard business plan is to put a barely-functioning product on the market right away and wait for the early-adopter customers to find the flaws. That's exactly what's happened. Detroit's plan is pretty much the opposite, but Detroit isn't developing this product. That's why dealers, for instance, haven't been trained in the cars.

  • FreedMike If Dodge were smart - and I don't think they are - they'd spend their money refreshing and reworking the Durango (which I think is entering model year 3,221), versus going down the same "stuff 'em full of motor and give 'em cool new paint options" path. That's the approach they used with the Charger and Challenger, and both those models are dead. The Durango is still a strong product in a strong market; why not keep it fresher?
