Automatic VS manual hubs!

Re: Automatic VS manual hubs!

I long ago found out (the hard way) that a 4 wheel drive is an expensive option that will just get me another 50' before I get stuck. With auto dealers @ $110 per hour labor, I don't cherish having problems in front electric hubs, front drive shafts (CV's), front differentials, or especially $1,000 transfer cases.

I bought my diesel crew cab truck in two wheel drive, and I can pay for 75 wrecker tows and break even. There again, I live in the South where we seldom see snow more than 1x per year.

Now, back to hubs and tow vehicles: Most serious off roaders like the simplicity of manual hubs on vehicles like Jeep Wranglers and older off road, jacked up pickup trucks--with their crash box manual transfer cases. You cannot kill'em. The old Dana running gear was also used in the 70-80's Dodges and Ford 4x4's.

But, most modern 4x4 truck owners seldom use their vehicles in seriously demanding conditions. Newer 4x4 trucks are mostly very nice vehicles, and they're better off with electric front hubs and electrically operated transfer cases.

I've always shied away from full time AWD/4x4 found in older GM trucks/SUV's, Mercury Mountaineers and Jeep Wagoneers--too much fuel usage and mechanical wear and tear. Both front wheel and rear wheel power often has to go through a big, wide chain in the transfer case to get to the driveshafts. Remember, $110 per hour labor.

Modern AWD cars are increasingly popular in the far north, some of which are masquerading as SUV's. These are generally front wheel drive vehicles that transfer part of their power to the rear axles when the front wheels spin. Their running gear is very weak, as is their suspension. They're good in snow, but really shouldn't be used as serious tow vehicles.

There's just no replacement for a full size pickup truck as a vehicle to tow your boat--2wd or 4wd. The most recent changes are in the usage of 6 cylinder engines, instead of 8 cylinders. 6 cylinder non-turbo engines are pushing 300 horsepower, and should run great. Ford's turbo 6 cylinder is actually stronger through a wider power band than the Coyote V-8 also used in the Mustang GT.

In everyday driving, the turbo 6 really gets about the same fuel mileage as the V-8. On the open highway, it gets a little better fuel mileage--but it is a $1,000 option.

That's my experience after 24 years' working for a major U.S. auto manufacturer.

Re: Automatic VS manual hubs!

I have a 98 ram with the cad, I thought they got rid of the cad in the gen 3's?

As far as wear and tear on the front end with the autos, I got 200,000 out of mine before I had to get new bearings and u-joints so I'm not sure that's a good argument (maybe I got lucky). Although I've had no problems with the cad, and not having to crawl through mud to engage the hubs is nice, I am curious as to the effect on mileage is with manual hubs. I've heard that one argued both ways also.

I'm not knocking cad but rather pointing out that unless the O/P worded it wrong, the question was about automatic HUBS and that cad vehicles are not relevant

I long ago found out the hard way that buying a 2wd pickup was a huge mistake that constantly made me feel crippled back into a grassy field to turn around and either bury it or have to repair my ruts after needing full throttle to reach the tarmac again. spinning on ramps. Sinking into anything softer than bedrock..... Yep snow too but I use 4x4 year round.


Different strokes for different folks aye? :D Of course we are both hijacking the O/P's thread at this point:eek:

Re: Automatic VS manual hubs!

If I recall correctly?...?..?.....Back when 4wd was first offered by the big automakers, it was all solid front axle trucks and jeeps or utility vehicles w manual hubs or constantly locked front axles, and for offroad or snow/ice/sand use only. The ability to shift on the fly was'nt an option unless the front running gear was connected to the wheels and just waiting for the transfercase to send power to the front axle when shifted to 4wd? IMO Simple, RUGGED, reliable, manual hubs are better in rigs that encounter deep water and slick mud and are used offroad frequently. AWD is best for daily drivers on slippery maintained roads and not built for high traction tires and lots of applied torque. But I am no expert on the new stuff!

Feel free to knock the cad, most agree that there's better ways to go.

You had said that jda's 2010 dodge had a cad and I was curious because I thought dodge got rid of the cads in 2002, aside from a 2010 1500 having an independent front end.

apologies for the mini hi-jack :redface:

Re: Automatic VS manual hubs!

I dunno.... I'm not a dodge fan and the newest vehicle I've ever owned is 1999... either way, no hubs on it

Had plenty of old chevy trucks with auto hubs and can't say anything bad about em 'cept that when the hubs finally do fail around 200k miles, they are more expensive than manual ones... My ford has an auto/manual (vacuum/knob) hub that doesn't always work right but it has over 320k miles on it.

Re: Automatic VS manual hubs!

I prefer manual hubs. Far more reliable in my opinion. I've owned and worked on both for years. Far fewer problems with the manual hubs from my
experience.
