Mine did the same thing. Did you get an answer for this problem? In refreance to the right front hub trying to lock in while driving in 2-high.

Get rid of the vacuum hubs and replace them with manuals as described at the beginning of this thread.

Same fix applies to SandraK.

Thank's axe man. Now the rearend is whining, so as soon as I get that fixed, I'll get the warn locking hubs. Thanks for all the GREAT info. <img src="/forums/images/graemlins/smile.gif" alt="" />

is there anyway to manually lock the vacuum hubs??? i have one that isnt working. i kinda in a bind right now and cant afford the manual hubs and i NEED the 4X4. thanks

Yes you can remove the hub,remove the snap ring from the rear of the hub.remove the gears inside,remove the yellow plastic circle in the bottom(Diaphram)in this spot i used a piece of shop rag to hold the diaphram out wich in returns hold the gears in the locked position.I DID THIS IN A BIND!! i wouldnt recomend doing this for long term use.

first of all i have a 2001 2dr kia sportage with about 140,000km on the clock its running in perfect condition but my 4x4 is not workin i get the light and everything so i figured the hubs are broken..

but wen i wanted to order them from warn i coulndt find a warn dealer in dubai and didnt find a place that can ship them so i was just wondering if anyone can help me with this thing send me an adress or a link to a site that can ship me the hubs to Dubai United Arab Emirates..

thnx all u can reply to me on mounib_moe@live.com

your advice on getting lockuot hubs is a good idea. I have a 2001 sportage. the hub vacuum seals are shot on one wheel, inner and outer bearings and needle bearing. Without that inner seal the same problem will happen again. The Kia retrofit kit is too expensive about $600 per side. My sportage was built between may 16 and july 20,2000. my problem is that i have all the new parts except these vaccuum seals. the dealer is not able to find the correct parts. the seals specified just dont fit. the existing seal is in 2 pieces one fits onto the back side of the knuckle and has to be pressed in. the other piece fits inside the knuckle piece then the half shaft fits into it. the hub piece has a part name forsheda A084032. the manual hub idea is a few years down the road after i take the vehicle tht my daughter has now. i am also wondering if the one seal is a part of the knuckle and they redesignedthe vacuum seal to fit inside the knuckle seal. please help

I have a 2000 Sportage with a manual trasmission. I've the vacuum line problems too, but here's something new. It had been about two years since my last problem with the hubs so I wasn't surprised when I went to use the 4-wheel and it didn't engage. First I tried replacing the vacuum hubs with the Warn auto mechanicals but this didn't fix the 4 wheel engage problem. Suspecting that I got something wrong or had a bad set, I decide to try the manual hubs. After installing the manuals and locking in the manuals, I took a test drive. When I shifted into either 4H or 4L, the green indicator in dash comes on, but the front wheels are still not engaged. This was confirmed by trying on both dry pavement (a short, low speed turn with no binding which should have happened) and by trying in a low traction situation were only the rear wheels spin. Tomorrow, I plan to jack up the front end and turn one wheel to make sure the other wheel turns in the opposite direction.

My question, what else could cause the transfer case to not supply power to the front wheels?

It is possible, but very unlikely that your transfer case in not engaging the front drive shaft. It would be best to put the Sportage up on a lift so all 4 wheels are off the ground and then engaging the transfer case into 4 wheel drive. Then put it into gear and looking under it to make sure the front drive shaft is turning.

More likely is that you have a Frozen Hub.

I have had a couple of times with my front manual hubs when they would turn completely, but not engage on the shaft. It was just compressing the spring and not pushing the coupler onto the shaft. This is referred to as a Frozen Hub. I had to pull them off, clean them, and then relube them. Then it worked.

I recommend pulling them off at least once a year and cleaning then relubing them just to make sure this doesn't happen.

Great info on the warn hubs...will get some asap. I had the truck up on stands and engaged the 4wd. The passenger side shaft was turning out of the differential, but the hub would not engage. Problem is, on the drivers side the shaft did not even turn. I just bought the truck and suspect the 4wd was never used. Any suggestions on this shaft issue?
