My Edmunds Vans newsletter arrived this morning with this tidbit:
Chevy Express Updated for '03
Change comes slowly to the full-size van market, but for 2003 Chevrolet has updated the Express van with a new look, better access and better powertrains. For the first time, the Express comes with a 60/40 left-hand-side hinged door -- a big concession to the minivan crowd that allows pass-through access to the middle row of seats. The front end has been restyled and reinforced for better crash protection, and a new range of Vortec V8 engines bumps horsepower on most models; a 4.3-liter V-6 is the base motor. All-wheel drive remains an option.
#288 of 655 just a question about your experiences with the Express
Jan 14, 2003 (8:06 am)
I have a chance to purchase 1 0f 2 2001 leftover conversions at a really good deal. 29,000? The only problem with going through this is that I already have an Astro which I'm trading in. The problem with that is it really stinks in the snow. I'm wondering how the Express is in the snow I live in New England where this year has been terrible but I really like my van other than sometimes I feel a little timid about driving it in the snow.The dealer says it goes great(but anything to sell a car) My children play travel hockey and I just don't want to get stuck. Any help or experiences you can give me would be great.
#289 of 655 Why are Turbo Diesel Injected engines not offered by GMC or any other make
Jan 16, 2003 (12:27 pm)
I like my Savana van; I would like it more if it were a TDI engine (Turbo Diesel Injected). I drove 3 different passenger cars last March year in France. They were all quiet, fast and very powerful - and they got tremendeous milage. They don't smell.
Open your eyes out there!
The GMC Duramax engine offered in the 4X4 sucks: it is loud (it sounds like a rock crusher).
The preconceived notions of EVERYONE that I talk to about this subject boggle the mind. The auto industry here is behind the eight ball-as usual. Every SUV on the road here should have a diesel TDI option.
#290 of 655 Express in snow

I just bought an Extended Express 3500 so that
is bigger than the conversion you are considering, but I have to say that the snow traction is horrible. I got stuck in the middle of a snow covered road on a mild incline. The rear just spins and can't get traction. Extra weight helps, so now I have an extra 400 pounds of softener salt store behind the back seat and that helps.
I suspect a limited slip differential would help alot. I have considered adding one, it seems you can do it aftermarket for ~$400-500.
#291 of 655 That was your problem

No limited slip differential. I haven't had my 2500 Savana extended passenger van (with limited slip) in heavy deep snow, but it handled itself well on snowy roads. Two wheel drive gives twice the traction over one wheel drive.It's a lot of weight to push (3 tons) with only one wheel in snow or sand to do the work, traction has to give way.

The term you are looking for is a locking differential. You have a limited slip differential if only one tire spins. Locking differential spins both tires so if one slips the power don't go all to that side, the path of least resistance.
If you are running the factory tires that is another slip factor. What tires came on the van Tombstone Steeltex? I had those on my 2500 4WD Yukon XL, they really performed poorly even in 4 WD they slid all over the place.

Your right, locking differential is the correct term (confirmed it at the GM site). It makes a BIG difference in snow. The term limited slip was used in the article previous to mine, guess I got confused.

Open differential is the standard diff. If one rear tire loses traction, you're not going anywhere.
Limited slip an option on most trucks and vans. Limited slip will send SOME torque--like 1/4 to 1/3-- to the other tire when one tire slips. For some reason, GM calls its limited slip a "locking differential." It is not, but it sounds better I suppose. Your factory limited slip will wear out within 30-40,000 miles or so and will need to be rebuild (clutch packs). Also, make sure that any grease put in your rear axle has the limited slip additive.
Locked diffs are not available from the factory anymore (but they used to be available on serious 4wds-- landcruiser etc). They are available for most fullsize vans and trucks, from aftermarket sources, but make some noise when engaging and disengaging. The normal state of affairs is that both tires are spinning with equal torque while the vehicle is driving straight ahead. If the vehicle makes then the differential must unlock, making the noise I mentioned. Most modern ones aren't very noticeable.

Yep mrnimmo is correct, GM does label it wrong as far as "locking" term goes. What you are talking about is the famous Detroit locker, GM stopped putting that in because of noise complaints, then deemed the "posi-trac" a "locking" differential. The lockers are still available aftermarket through companies like DTS or Power Trax.
As far as mileage goes I have 47K on my YXL and still get both tires going on ice/snow/water, I guess it depends on how often you need the extra traction.

>What you are talking about is the famous Detroit locker, GM stopped putting that in because of noise complaints,
Funny, I've been in trucks with these and I never thought the sound was obtrusive or that the locking and unlocking was noticeable. Of course, maybe I'm just getting old.
