super piston slap nvh killing you with kindness

While Noise, Vibration, Harshness (NVH) control built into a modern machine is normally your friend, it often kills you with kindness. That’s when NVH hides things that should never be hidden. Shameful. Cowardly. Pathetic. And while I wasn’t expecting this level of deceit when merely replacing the shift knob on the otherwise stock transmission in my 2011 Ford Ranger…well it was thrust upon me. And it can happen to you, too.

There was a time when you could simply unscrew the factory shift knob on any basic machine (cough, 2011 Ford Ranger) and replace it with whatever the heck you liked. Something with a little more style than stock. Or something with more heft, giving a nicer quality feel in your hands. I had a solid 8-ball shifter remaining from the T-56 swap in my Fox Cougar, and I certainly thought it would look choice on the truck. So I began pulling the factory part off. Oh man, what a mistake THAT was…

So apparently the shift knob isn’t a normal “twist and spin-off the threads” type of deal. The forums mentioned a way to pull really, really hard to pop it off the threads, and I’ve seen that done elsewhere on other vehicles…so I gave it a shot.

While those scratches weren’t from my teeth, they sure felt like it. No dice.

I wound up ripping off the rubber knob skin with my Leatherman tool, then attacking the hard plastic covering with a ball-peen hammer. I was left with this metal hunk, and the remnants of the plastic covering wedged between the shift lever and the shift knob. How many vibration quelling layers are there to this thing?

Back to the top photo. I wised up and did what others suggested: remove the shifter assembly. Which is another multi-layer, sleeved, affair with NVH reducing content. But with one bolt, I made it all go away. But was I gonna try to remove the factory knob on my workbench? I already mangled the damn thing up pretty badly, and the scratches could be present when I install the 8-ball knob. So I punted on 4th down. I called in my kicker, eBay motors, and got what I really wanted instead. Sure it cost me a few too many dollars, but…well…

BAM SON! What you see here is the chrome lever from the Ranger FX4 Level II, the aforementioned 8-ball knob, and the faux-leather boot from a 1991 Mustang LX 5.0 Notchback. (Yes, I had to add the Notchback part, as that makes it cooler). All this stuff together makes for a far superior design, deserving to be standard issue on ALL Rangers of the U-shift-it variety. Aside from the slick chrome plating (mixed feelings with all this black plastic) and the unbelievably better ergonomics of the FX4 lever, this part has very little NVH interference. To wit:

  • Huge, thick, air tight(ish) noise quelling rubber boot? Gone.
  • Multi-layer Knob sporting chintzy plastic and rubber covers? Nope.
  • Sleeved shift lever with some rubbery stuff sandwiched between them? History.

Now remember I said that the stock stuff can kill you with kindness? That doesn’t mean you want to be physically abused: word has it that the Hurst replacement is a bit over the top for most folks, even if the price is nice. So the Ranger FX4 part has the right look and feel, and it’s a fantastic piece of OEM engineering. I can now shift without my elbow ever leaving the armrest. The notchy engagement is now faster, and you can feel the notches instead of just wondering WTF is wrong with the gearbox. Vibrations through the shift knob are minimal, but present. Hammer the throttle in first gear and the lever emits a gearbox whine that–with my modified air filter housing and 2010 Mustang GT muffler–gives the DOHC Duratec Ranger a Pre War British sports car’s demeanor.

You can’t help but smile a little as you twist up the little Duratec Ranger through redline in the first three gears. OR A LOT. This is just so frickin’ cool. And it’s so damn hard to find this anywhere in the world of new vehicles sold in North America.

My point? Just about any vehicle can be de-wronged, fixed to your liking. Don’t be killed by kindness, you need not be a victim any longer!

    I continue to be jealous of your sweet, sweet Ranger mods. I have considered the Hurst unit, but they're hard to come by without spending several hundred dollars, and most of the folks over at Ranger Power Sports who have them report leaks from the gasket after installing. Not that transmission fluid will ruin the rubber floor mat in the Banger Ranger, but still not something I want to have to worry about after installation of a week's pay-worth of shifter. The FX4LII shifters are getting kind of rare! Good find.

    This is why there is a Nardi wheel, shift knob, and ebrake handle in my basement waiting for me to get back from the Stahn and put them in my 1st gen Miata. Not so much the NVH aspect, just don't like to feel like I am in an 80's GLC when I look at the wheel or grab the shifter.

  • Carsofchaos Bike lanes are in use what maybe 10 to 12 hours a day? The other periods of the day they aren't in use whatsoever. A bike can carry one person and a vehicle can carry multiple people. It's very simple math to figure out that a bike lane in no way shape or form will handle more people than cars will.The bigger issue is double parked delivery vehicles. They are often double parked and taking up lanes because there are cars parked on the curb. You combine that with a bike lane and pedestrians Crossing wherever they feel like it and it's a recipe for disaster. I think if we could just go back to two lanes of traffic things would flow much better. I started coming to the city in 2003 before a lot of these bike lanes were implemented and the traffic is definitely much worse now than it was back then. Sadly at this point I don't really think there is a solution but I can guarantee that congestion pricing will not fix this problem.
  • Charles When I lived in Los Angeles I saw a 9-5 a few times and instanly admired the sweeping low slug aerodynamic jet tech influenced lines and all that beautiful glass. The car was very different from what I expected from a Saab even though the 900 Turbo was nice. A casual lady friend had a Saab Sonnet, never drove or rode in it but nonetheless chilled my enthusiasm and I eventually forgot about Saabs. In the following years I have had seven Mercedes's, three or four Jaguars even two Daimlers both the 250 V-8 and the massive and powerful Majestic Major. Daily drivers of a brand new 300ZX 2+2 and Lincolns, plus a few diesel trucks. Having moved to my big farm in central New York, trucks and SUV's are the standard, even though I have a Mercedes S500 in one of my barns. Due to circumstances with my Ford Explorer and needing a second driver I found the 2006 9-5 locally. Very little surface rust, none undercarriage, original owner, garage kept, wife driver and all the original literature and a ton of paid receipts and history. The car just turned 200,000 miles and I love it. Feels new like I'm back in my Nissan 300ZX with a lot more European class and ready power with the awesome turbo. So fun to drive, the smooth power and torque is incredible! Great price paid to justify going through the car and giving her everything she needs, i.e., new tires, battery, all shocks, struts, control arms, timing chain and rust removable to come, plus more. The problem now is I want to restore it and likely put it in my concrete barn and only drive in good weather. As to the writer, Alex Dykes, I take great exception calling the 9-5 Saab "ugly," finding myself looking back at her beauty and uniqueness. Moreover, I get new looks from others not quite recognizing, like the days out west with my more expensive European cars. There are Saabs eclipsing 300K rourinely and one at a million miles and I believe one car with 500K on the original engine. So clearly, this is a keeper, in love already with my SportCombi. I want to be in that elite club.
  • Marky S. I own the same C.C. XSE Hybrid AWD as in this article, but in Barcelona Red with the black roof. I love my car for its size, packaging, and the fact that it offers both AWD and Hybrid technology together. Visibility is impressive, as is its small turning circle. I consider the C.C. more of a "station wagon" by proportion, rather than an “SUV.” It is fun to drive, with zippy response and perky pick-up. It is a pleasant car to drive and ride in. It is not trying to be a “Butch Off-Roader”, or a cosseting “Luxury Cruiser.” Those are not its goals or purpose. The Corolla Cross XSE Hybrid AWD is a wonderful All-Purpose Car (O.K. – “SUV” if you must hear me say it!) with a combination of all the features it has at a reasonable price.
  • Ernesto Perez There's a line in the movie Armageddon where Bruce Willis says " is this the best idea NASA came up with?". Don't quote me. I'm asking is this the best idea NY came up with? What's next? Charging pedestrians to walk in certain parts of the city? Every year the price for everything gets more expensive and most of the services we pay for gets worse. Obviously more money is not the solution. What we need are better ideas, strategies and inventions. You want to charge drivers in the city - then put tolls on the free bridges like the Brooklyn, Manhattan and Williamsburg bridges. There's always a better way or product. It's just the idiots on top think they know best.
  • Carsofchaos The bike lanes aren't even close to carrying "more than the car lanes replaced". You clearly don't drive in Midtown Manhattan on a daily like I do.
