Why dont subes have free-wheeling hubs


Recommended Posts

I asked that question a long time ago. MOst older 4x4's had lockout hubs available, were RWD with the front drive train added as an option. There are some who argue that they really fon't buy you anything in terms of wear and tear savings, I don't know. I have experience with 72 Dodge, 73 Chevy, 85 Ford and my 83 and 97 Nissans, all with Manual hubs on the front. Of course the subarus are(were) FWD cars with the rear added as an option, like my long gone 80 wagon.

 

I am not an expert on Automatic hubs, have heard some negatives in terms of reliability and on some the drive cycle needed to lock and unlock them-to engage put in 4wd and drive straight forward 6 feet does you a lot of good when you drop in a hole and you need 4wd NOW to get out.

 

I will say if you have lockout hubs, make sure they are good ones (and keep them greased)-I have seen the plastic ones fall apart at the worst possible moments, the hubs on my 97 Nissan got so bad I replaced them with all metal Warn lifetime warrenty hubs.

i certinly enjoy the conveniance of push button shift on the fly 4wd. However I can understand the advantages of locking hubs.

 

In 94 I baught a 1970 FJ40 landcruiser for $500 . It had push button 4wd and fixed front hubs. Just for fun I decided to look at the front diffy oil,, it was a metalic slime . I can only assume that that oil had never been changed and those front diffy gears had been turning over 25 years.. First thing I did was change the oil and put warn locking hubs on it. the results were less noise and a very smooth sharp turning raidius in 2wd.

Oh and to show how much of a moron I am I sold it for 1500 :banghead:

 

At on time Mitsabishi had a SUV you had to back up 20 feet to disingage the hubs

Dad has a hilux that has freewheeling hubs that are recomended to be disenganged when driving in 2wd mode

 

Why dont subes need freewheeling hubs???

I think to answer your questions... We don't have free-wheeling hubs because getting out to lock and unlock your hubs and drive forward and backward and crap is a PITA. Subes don't need freewheeling hubs because we have a lever or button that engages or disengages our rear-driveline. Right? IMO this is a much better design and less likely to CRAP OUT like freewheeling hubs.

For sure, it is an easer setup, however,,,,even in 2wd the rear differincial gear and the pinon gear are still meshing and turning causing drag wear, not to mention the drive shaft UV joints and the carrier bearing are still turning. Even if you never used 4wd, rear differincial maintinance is still a must.

 

but as archemitis said, "it's a car" so convience is more of a priority than utility.

Don't get me wrong,,, I absolutly love the fact I can hit the button at 35mph and drop from 4wd to 2wd or vice-versa in my subee. That whole backing up to disingage the hubs in other vehichles, like the mitsabishi and some older Fords, is for the birds.

Yup. My dad had a 95 Kia Sportage that had the auto hubs die on him. I slid off the road because of those dead hubs. Subaru driveline is much better. Never have to lock/unlock any hubs and the maintenace is not bad at all.

Dealership gave me a KIA Sportage as a loaner while my Rio was getting some work done. I went down to this dirt parking lot that has a bunch of what look like mogels made out of dirt. Put it into 4Lo and locked the AT into 1st gear. I was impressed; had WAY more gear reduction than my Subaru!

Dad's sportage was a 5-speed. I think low range is about 1.9:1. Yup overall, Dad and I were very impressed with the sportage. In fact, Dad was debating going back to a sportage. Then he test drove a 97 outback wagon with 114k miles on it. He decided to go with the Outback since he already had a truck.

I've been toying going with a sportage. It does alot better off road than my Suby does, it gets the same mileage as my roo, and it's got a frame. However, the insurance would kill me: Too new of a car!:banghead:

I think the MAIN reason for having locking hubs is for economy. Take my 92 Dodge for example, driving back and forth to school I get 12.6MPG, but if I lock the hubs I get 11.7. Says in the manual to unlock the hubs when not in 4WD for better economy, but in bad weather leaving them locked is okay. I usually just leave them locked if the weather is going to be bad, since I'd rather just reach down and slap it into 4WD without having to get out in the blowing snow to lock the hubs.

 

I think that since our soobs are so light, that having locking hubs, even automatic ones, wouldn't save much in fuel mileage so they decided not to do it.. But look at like older Cherokees, most of those didn't have hubs either...

That and what's cheaper - a locking hub or just a splined axle with no hub at all.

sry i just really hate kia

Reasons for locking hubs:

increases gas milage. The lack of half the drivetrains rolling resistance helps

Reduces cost of drivetrain. The parts between the transfer case and the hub don't have to be rugged, because they are only used intermitantly.

 

Drawbacks.

They break. always at the wrong time.

They get stuck. ANyone ulse used hot water and a hairdryer to get the hubs to lock in winter?

Autolocking hubs are notorious for shattering or stripping.

 

How many rear axels and differentials do you hear of going out on a subie?

The rear end is built for full time drive duty, as used in datsuns, so it has no problem doing part time drive duty and just spinning the rest of the time.

 

I personally find locking hubs a PITA, but they are so common that people get in the mindset that manual lockers are the best because they are better than autolockers, ignoring the fact that you don't need a disengagement option anyways.

That's your opinion becuase not everyone hates KIA. I love my KIA Rio. It's a 2002 and much better than the 2001 and 2000 models. I have yet to have any major work done to it, there is a 10yr/100,000 power train warrenty (5yr/60,000mi bumper to bumper), it gets 30mpg with my lead foot driving, and goes 90mph on a regular basis; maxing out a 110mph. My car payments are $162/mo and insurance is $99/mo for it; that's cheap as hell for a 'new' car. It's a very economical solution to my requirments for a daily driver.

 

I think you exceeded the vehciles limited capabilities. The Rio barely fits 4 ppl; let alone 5 ppl. I tried to push my Subaru with my Rio when the Subaru was dead. Couldn't move the Subaru; just slipped the clutch in the Rio. Did I blame KIA? No.... I blamed myself for exceeding the capabilities of my vehicle; the clutch in it isn't rated to tow/push another vehicle.

All a lock out hub does is idsconnects the wheels from the rest of the drive train. In a subaru, the rear drivetrain spins weather in 4wd or not. New jeeps don't have locking hubs, the front drivetrain just spins all the time.

 

And yes, auto locking hubs suck. I would much rather just have everything spinning or jump out and lock in my hubs that always wondering if the auto locking hubs are working or not.

Ok. But how do you feel about punctuation and complete sentences?;)

 

I had a brand new Kia for 5 years. put about 125k on it. Never had any trouble. Sold it to my best friend. It died at 190k due to a redneck in a lifted ford f-250 and his apparent lack of familiarity with the meaning of a red light.

 

Destroyed the Kia. But my friend walked away unharmed. Not too shabby for a $10k car with 190k on it.

K.I.S.S

Thats what its all about.

 

Why dont we have them??? Cause we dont need them. Its one less part to fail and Subaru knew it would be beating around the bush to try to develop one. Our 4WD is nothing like that of a conventional truck with locking hubs. Our transfer case is completly different and our drivetrain is completly different.

 

However, i thought of adapting locking hubs for the rear to run a locked rear end without having to remove axles when on the street. Idea never made it far.

Because its way easier to just unhook an axle than it is to retrofit and adapt some lockout hubs.

 

 

 

Also note what Calebz said; and that was an older KIA. The newer ones are so much better than the older ones. I test drove a 2000 Rio and said NO WAY. Two years later I test drove the 2002 and could tell it was SO much better; financed $8,000 and had me a brand new car :drunk:

The biggest thing I have heard around here were I am at with the auto lockers is the electric drive motor that ingages the transfer case. Usually strips the gears out and from a few mechs that I know., its mostly from lack of use that does it.

 

I dont know how my AWD really works but I love it. I have drove around trucks stuck in the snow. All I do is let the front spin slightly untill the rear kicks in and away I go.
