Re: Cars

Shocks that have different resistance on the same vehicle can cause cupping on certain tires because they'll bounce and lose contact with the road.
 
Re: Cars

Cupping and scalloping is as described and will occur with misalignment as noted...and failure to rotate at reasonable intervals. I've never heard of shocks causing that but misaligned struts or struts with worn mounts could I'm sure.
An Alignment is the first place to start. Maine roads beat the crap out of vehicles,I'll bet his has never had one done
 
Re: Cars

Yes...that would be an excessively worn shock or a shock incorrect for the application since the primary function is to absorb uneven pavement / bumps and keep the tire in contact with the road. I was assuming properly functioning shocks...my fault.
 
Re: Cars

Alignment should not affect a rear tire. MUCH more likely that shocks are the issue. Flat spotting that goes away is not. So I agree with alphablue. And I'm licking my chops for the release of the Focus ST.

Yeah right, they don't do 4 wheel alignment on must every car sold today

I'm waiting for the Fiesta ST. Which will be a year after the Focus ST. Initial reviews are, well, darned good for the ST.

Wanted for several years to get back into a Wrangler after driving one thru the mid / late 90s. Having some fun on recent dry, warm sunny days. Happy motoring...I just try to recall a fond memory during frequent refueling stops.

The 2012's have an updated engine and transmission which get a somewhat tolerable 17 city/21 highway.

Or you get hold of a Cummins 3.9 turbo diesel and drop that in. Enjoy your 28 MPG and 400 lb ft of torque.

According to my MPG instrument cluster readout...I'm not approaching those numbers. I don't know how accurate this indicator is. This is a 2012 with the Pentastar 3.6 and 5 speed auto. I'll have to do a more accurate assessment myself. I was never a fan of diesel...back in the day of the very noisy, stinky diesel but would seriously consider one now after driving a couple more current, quiet and cleaner diesel power plants. They do have swap kits for Chrysler Hemi engines for the Wrangler. With the swap kit and the Hemi installed you'd have a nearly $50.000.00 Wrangler...so probably not for me.

yes they do a thrust alignment on irs cars, however it is almost never out and is mostly a way to sell you on how good they are and get additional revenue. Plus the milage of 87k is the time that shocks typically wear out.

We've had our 2012 Focus SE sedan for a year now, in race red of course (taking a que from WI and Ferarri), and we just love it;41 mpg highway, 32 local, great handling, awesome looks. I really wanted the Titanium model, but that was way out of the price range. The ST is going to be more insane.
 
Re: Cars

Honestly, I think the 2liter turbo makes more sense in the new Fusion. W/o AWD, I'm not sure how much of that power the car can actually put down when starting from a stop. Once you get going though, I'm sure it'll be fun as h3ll. Sort of like a similar car that I have some experience with, made by one of Ford's former partner companies.

Re: Cars

The 4-door regular Focus, meh. Looks like a large-mouth bass.

The 2-door Focus RS, very yes.


As for the horsepower, does Ford offer a limited-slip transaxle? That seems to be the answer, if AWD isn't happening.

I would guess they would do limited slip electronically at this point. If the ECM senses slip, it kick over to a different fueling table, or applies a variable offset designed to keep the powertrain producing the maximum amount of power before the tires let loose. At least, that's how I'd do it. Tossing an extra table or control loop into a cal is cheaper than actual hardware.

I'm glad to see the Ford is making a car that gets all of you car drivers all wet between the legs, that's a good sign for the company, and Ford is company that I love to see do well. But I won't be buying one any time soon.

I've had my truck for 4 years...I'm thinking its about time to hook my laptop up to it and make a few tweaks...I'm thinking a reasonable goal without hardware changes is 4-digit lb-ft of torque.
 
Re: Cars

Bingo. Per Autoblog

Ford has included an electronic limited-slip differential, which relies on the traction control software to individually brake the front wheel experiencing deteriorating traction, diverting power to the wheel with purchase.

(regarding things like torque steer) Hau Thai-Tang, Ford's Vice President of Engineering, Global Product Development, tells Autoblog that the Blue Oval has actually intentionally left some of this sensation in – it could have curbed the condition even further through more aggressive tuning. Instead, engineers left in a hint of 10-yard fight as a subtle challenge to drivers – a reminder that they're at the wheel of a powerful, performance-minded machine.

Seems like they've set the nanny dial to low. Kudos, if that's true. Mazda's nanny is dialed up a bit much for me.

Makes sense that they'd individually brake, rather than selectively cut fuel, with the philosophy ABB mentioned above.

And once you do that, you can work on dropping that crate engine into your Jeep. :D

I do engine controls, so that's the way I'd do it, I have no interest in getting into full vehicle system controls. :p

Yeah, that project has been put on the back burner, all of my spare funds get poured into the house now. I need to find a new transmission before I do anything more. No way am I bolting that Peugeot piece of **** behind a 3.9 liter Cummins.

No crap. That BA-5/10 (I forget which) would have a very short, very exciting life behind the Cummins. :p On the other hand, once you finish the engine swap, you may as well drive it until one of the differentials or the TC breaks, since I suspect those are next up behind a diesel.

The ST reminds me of one of the fun cars of my misspent youth.
Not mine...I just always wanted one! :)
