Front end noise #1038964 12/07/11 06:59 PM

I have a grinding type of noise coming from the front end of the vehicle. I mostly hear it when I let off the gas pedal, the truck seems to drag a bit. I know I am going to be changing my front hubs out very soon because they are always locked in.
When I take the hub off the tires spins freely but when I put the hub on I cant hardly get the tire to turn. When I change to warn hubs, hopefully this will stop that problem.

If anyone has a clue as to what the front end noise may be, please respond. I am going to go out and check out my wheel bearings again to see if something happened again.

ok, let me get this straight, I went out and checked my wheel bearings, they seemed a bit loose so I tightened them up until the tires didnt wiggle anymore, then spun the tire, it spun freely but when I put the hub back on it didnt spin much at all. I believe that my air hubs are locked in the out position which actuates the front axle.
Is it supposed to be that way? I dont think the front axle is supposed to spin when in 2wd.

Hey guys, can I just gut the front hubs and replace the empty caps on until I get new ones?

if you're going to gut them, may as well take 'em apart and clean them out. probably just rusted together. but it should be fine to gut 'em and put 'em back on.

So, i bought an 01 Kia Sportage. before i even drove it, i nick-named it The Goat.. it has been just like a goat.. stubbern at every corner...

I recall some postings about reversing the innards of the stock hubs to get them to be engaged at all times. I think this was done to Canadian models because of failure issues with the hubs. Maybe this was done to yours?

01 Convertible; Electric Fan; 3" Up Your Kia lift spacers; Tj 104's; 31x10.5x15's on Centerlines; Rear LSD.
GONE, all I have left are a few spare parts and the wheels.

after pulling apart my hubs i can very that yeah, that could be done. you just have to flip the position of the spring..

Pet peeve of mine. I have to bring this up. When I took my factory hubs off to clean and grease them while greasing my bearings a few years ago, I read on the inside of the hubs "Warn". Our factory hubs ARE warn! They are not crap hubs! However the system that holds the vacuum TO the hubs are a different story I must admit. If there's a vacuum leak ANYWHERE in the 4wd system, both your hubs will not engage. Sometimes a small leak will create intermittent engage/disengage issues on one or both hubs. Also, the 4wd hubs' vacuum will be lost if you are excessively holding the throttle at or near wide open throttle (WOT). The WOT condition means the engine cannot create vacuum in the intake cause the throttle body is completely open. As soon as you let off the gas the hubs re engange. Most the time you don't notice a disengage though because most the time your in WOT in 4wd, the drivetrain holds the hubs in 4wd with tension. 4wd disengages best when coasting or lightly tapping the gas..
Now that doesn't answer why your 4wd would automatically engage itself even in 2wd.. Here's the likely answer, Either you have an internal hub failure or your 4wd solenoid is not closing off completely. See, when going back to 2wd, that's when the solenoid is put to work, it has to keep the vacuum from pulling air past it, but when it's in 4wd it opens and allows the air from the hubs to pass the solenoid and enter the engine.. 4wheeling is a dusty pleasure so those hubs are prone to sucking in dust which in turn passes up the vacuum lines to the solenoid and partially blocks the seal inside that is supposed to seal off the 4wd system while in 2wd. This partial vacuum can be enough to pull the hubs in and out of engagement.. this is detrimental to the hubs since the transfer case isn't spinning the front drive train. So the hubs try to engage spinning wheels onto front axles that are not spinning at all.. It can make a random squeeling noise (splines rubbing but not engaging) or a loud clunk (sudden engagement). Anyway, for my story it was a happy and I have had working OE (warn) hubs since I've bought it nearly 6.5 years ago. The problem was solved for me by replacing the cracked vacuum lines in the wheel well (cheap vacuum hose) and blowing pressurized shop air through the solenoid both ways. The solenoid is located near the brake master cylinder just in front and to the passenger side of it i think if I remember right. Sorry for the novel but I've personally experienced what i'm mentioning. The other end of the problem which I read on here to be more common is the actual hub seals seal. usually it's after someone worked on it but the driver never correlates it to the last service because they haven't used the 4wd for 4 months or more. Example.. turning the rotors on a sportage on the bench lathe means you must pull the hubs off. If you did a front brake service in may, it's possible to have a damaged seal and not know it till november when snow falls. Again, sorry for novel. <img src="/forums/images/graemlins/drunk.gif" alt="" />
