Miscellaneous Ramblings - Suzuki Canada's Golden Opportunity


Suzuki of America recently announced that it will no longer sell passenger vehicles, focusing instead on its more successful motorcycle, recreational vehicle, and outboard motor product lines.

Immediately afterwards, Suzuki Canada released a statement asserting that it would continue with business as usual in Canada. (See the Star's coverage of that news here.)

Given some of the relative crap that Suzuki sold in the States (see below) - which did not precisely mirror what was sold here - and Americans' general disdain for smaller vehicles in general, Suzuki USA's weak sales aren't really all that surprising.

Part of the blame lies with General Motors. GM used to have a good-sized stake in Suzuki, and numerous Suzuki products were sold in both the U.S. and Canada wearing various GM badges, particularly from the mid-eighties to the late nineties. The Chevy Sprint? A Suzuki Forsa. Geo Metro? Suzuki Swift. Chevy/GMC/Geo Tracker? Suzuki (Grand) Vitara.

GM's CAMI assembly plant in Ingersoll, Ontario was originally a joint-venture, building Metros and Trackers, eventually returning the favour with an expanded version of the Chevy Equinox being sold as the Suzuki XL7. Well, sold by the dozen, anyway.

The Suzuki/GM relationship soured somewhat when General Motors bought ailing Korean automaker Daewoo in 2001, giving the General ready access to a newly redesigned generation of compact and subcompact cars built in a relatively low labour-cost country. In the U.S., doubtless with GM's influence, Suzuki ended up shilling several Daewoo products as their own; versions of the Daewoo Lacetti, sold in Canada as the Chevy Optra and Optra5, became the Suzuki Forenza and Reno, while our Chevy Epica (actually Daewoo's flagship, the Leganza) was their Verona.

Worse yet - in an insult to everyone - the Chevy Aveo (sold in both countries; it was the four door version of the Daewoo Kalos) became Canada's Suzuki Swift+. I'm guessing the "+" was to differentiate it from the vastly superior "nonplussed" Swift sold in the rest of the world.

(From the "where did that come from?" department, Suzuki also briefly sold a version of the Tennessee-made Nissan Frontier as the Equator. Available on both sides of the 49th, it was a good truck, but not an obvious fit for Suzuki's product portfolio. Confused buyers stayed away in droves.)


European-spec Suzuki Swift Sport
GM's financial troubles eventually resulted in GM selling most of its stake in Suzuki, which has since gone on to form a co-operative agreement with Volkswagen. Maybe VW was flattered by the startling resemblance between Suzuki's Kizashi and the 2006 Jetta.

While the loss of car and truck sales in the U.S. may be detrimental to Suzuki on the whole (or maybe not, if it was losing money doing it, as this pull-out suggests), this could well prove to be a golden opportunity for Suzuki Canada. Previously, Suzuki's American operations would have had an overpowering influence on product-planning decisions. Now Suzuki Canada is effectively master of its own destiny, at least within the confines of what its Japanese parent allows. Rather than try and move upmarket, as they did with the coolly received (but actually quite respectable) Kizashi, they should play to their strengths.

The Canadian market is much more Euro-centric, particularly in Quebec. We like smaller cars than our southern cousins. Suzuki's specialty is building small cars profitably, to the point where they build or license small cars globally for brands as diverse as Fiat, Subaru, and Nissan. They make small, we like small - sounds like a good match.

European-spec Suzuki Swift (special edition model)

I'd suggest that Suzuki Canada's first move be to bring in the real Swift, and do it, well, swiftly. There's a four door version of the two door hatch seen in the above photos that's nearly as good-looking, and from all accounts that I've read, it's a really nice car to drive too.

So c'mon, Suzuki Canada, bring on the Swift. And don't forget to market it.

(You might want to try offering all-wheel drive in the sedan version of the SX4, instead of just in the hatch, while you're at it - and again, this time actually promote the feature, Subaru-style. I'm just saying, I think that would work...)

Jackass Award - Ford Edge/Lincoln MKX Rear Hubs

2007-ish Ford Edge

Lest anyone get the impression that I live to pick on GM, rest assured that it is a regular occurrence to find questionable design or engineering choices from virtually every automaker. If it hasn't happened for me with a particular brand yet, it's probably because I simply haven't had to work on many of that brand's products.

Today's example is a Ford Edge. I think this one is a 2007, but they're the same from 2006 on, as is the Edge's Lincoln MKX twin.

Wheel bearings, a.k.a "hubs" or "hub assemblies" are by nature wear items, though there are a great number of vehicles that reach the end of their service life never having had one replaced.

All the same, you've got to figure there's a decent chance that someone will need to replace them at some point, so why not make them relatively easy to replace? You'd think this would also make them easy to install during assembly, right?

Ford Edge rear axle as seen standing beneath the cargo area, facing right rear. Note the hidden Torx bolts.
Meet the Ford Edge. In a front-wheel drive Edge those Torx-head bolts seen above would be sitting in a wide open space. Not so with all-wheel drive Edges, since the rear CV shaft (axle) and its large ABS tone ring (the toothed piece, which is part of the ABS sensor) do a good job of blocking service access. Clearly, this suspension arm is assembled prior to there ever being a driveshaft in the way.

Detail view of rear hub assembly fasteners.

Because they're so close to the ABS tone ring (don't dare damage that - ABS issues can result), and because there's only a direct, straight-line access to one of the four bolts (due to interference from the rear springs, etc.), they're an awkward nuisance to work with. Almost makes the Volkswagen Tiguan's rear hubs seem user friendly.

As a bonus, it does give your friendly technician an opportunity to buy yet another expensive tool set that he/she will use infrequently at best - and even this specialized tool had to be partially disassembled (Torx bit removed from its socket to be turned by a wrench instead) just to remove and install one of the bolts.

Long-reach 1/2" drive Torx socket set.
It didn't have to be this way.

The spread of the bolt pattern could have been a few millimeters wider, or, better yet, the bolts could have been fastened from the other side through the hub flange. Conventional hex head bolts could have been used.

This Award may be shared in part with Mazda, as there's some shared engineering in the Edge. The Edge's origins, via a convoluted path, lie in the original Mazda6's platform, courtesy of the Ford Fusion - a common basic architecture known at Ford as CD3. (Perhaps I should have paid more attention the last time one of those cars came in.)

For making this part more difficult to service than is really necessary, Ford (and maybe Mazda), please allow me to present you with a Jackass Award.


Admit it - you were curious what this part looked like, right?

Jackass Award - The Lazy Blogger

ZZZZZ...

No, the Award's not for the cat. Shelby is just doing what cats do best - she's stalking a mouse. And sleeping. Which is what I've been doing recently with this blog.

For leaving this blog unattended and in dire need of an update, I'm going to have to give myself a Jackass Award.

See? No favouritism here at Loose Nut.

Jackass Award - GM's Theta-platform Front Hubs


2005 Chevrolet Equinox
This is a 2005 Chevy Equinox, one of a trio of first-generation Theta platform mid-size crossovers that General Motors sold in North America, the others being the Saturn Vue and Pontiac Torrent. The Spring Hill, Tennessee-made Vue came first, introduced as a 2002 model, with the Ingersoll, Ontario-made Equinox and Torrent following in 2004.

Seen below is the front hub assembly from the Equinox pictured above; a Torrent would be identical, a Vue similar. Incorporated into the hub is the front wheel bearing, which is a wear item, and a common failure part in many vehicles, though I can safely say that it's a particular weak spot in numerous GM vehicles. When the bearing portion of this part fails, it can result in excessive play, noise, or both. This one was noisy.

Front Hub Assembly - Before
So why is this worthy of a Jackass Award? Well, it's not for the failure rate, which, to be fair, may or may not be statistically significant - my sample area includes a higher than normal percentage of GM vehicles, after all. Not for using a hub design, which while more expensive to replace, is far, far easier to change than the press-fit wheel bearings frequently found in such applications.

No, the Jackass Award goes to the engineering team for this part, who obviously felt that it was not only a good idea to fit a steel hub into an aluminum steering knuckle (steel and aluminum don't play well together, especially in the presence of salt), but to do so with NASA-level tolerances that made this part a tight fit even before the swelling effects of corrosion became a factor. The bolts are what actually hold the hub in place, and there are several other vehicles where there is clearance or even cutouts around their hubs, so this one-step-short-of-press-fit design was unnecessary.

The end result is a hub that is remarkably reluctant to part ways with the knuckle. So reluctant, in fact, that it normally has to be beaten to a pulp to be removed. (The rear hubs on these vehicles don't exactly fall out either.)

Forget using a slide hammer here, as that will just pull the flange out of the bearing. The most effective extraction method, short of removing the knuckle/upright and putting it in a press (which no sane mechanic would want to do), is to baseball-style swing a Bloody Big Hammer at the flange until the hub and knuckle declare defeat, or the mechanic passes out. You can see what the hub looks like after 15 minutes of intermittent hammer swinging in the photo below.

I did mention the aluminum knuckle, right? Be careful not to hit that with the BBH - it's not really forgiving if you hit it in the wrong places. It's not unusual for the sheetmetal dust shield to suffer during this process, either. If it isn't rotten already. Don't worry, the dealer stocks it; you won't be the first to kill one.

Extracted Hub - After 15 minutes of on-and-off pounding, it's feeling a bit out of shape...

You'd think that a vehicle designed in North America and built in Canada would take corrosion into account. As you can see below, corrosion is definitely a factor here. (The machined face of the knuckle has already been cleaned in this photo.)

See the corrosion?
Oddly, the nearly identical component set in a similarly-sized Chevy Uplander minivan does not suffer from the same problem. Yes, it fails regularly, and it does use an aluminum knuckle with a steel bearing, but it normally comes apart with little fuss.

For designing a serviceable part in a manner that makes it far more difficult to actually service than it ever needed to be, while simultaneously failing to take into consideration the real-world environment that this product would face in its primary market, please accept a Jackass Award. A great example of Bonehead Engineering.

...and here's what the new unit looks like. I couldn't leave you hanging.
