#95 of 122 Re: Confused on 4wd [dper299] by wiwally Mar 26, 2009 (10:26 pm)
Replying to: dper299 (Mar 23, 2009 6:30 am) Sorry took so long...only get my email work (and work the w/e shift!) I worked on an '01 which has Ford's latest setup (cv front axles with no disconnect other than the t-case) My parents had a '94 with auto locking mechanical hubs (still different from yours). You have managed to get a model year with what i would consider (and many, many others!) to be Ford's worst idea! (SORRY, but its true!) Here's what i found on your system: Your hubs are called Pulse Vaccuum Hubs (PVH) and are found on model years '98-'00. Basically vaccuum is supplied to each of the front hubs, which locks them in. They work off a vacuum pump which is supposedly located under your air filter box. Check to make sure it is working; if it appears like its working go on to the vacuum line(s)? that lead to the front axle from the pump and check for any leakage. Next check the front hubs. The locking hubs are the black caps in the center of each from wheel…..they snap on and off..(hard to take off without breaking a few tabs, so be careful)..There are seals on these hubs, one or both may not be holding the vacuum created by the pump. If you have a leak anywhere, the hubs are rendered useless. Best bet is to replace with manual locking hubs or this will be a continuous headache. Search AVM hubs on the net, you’ll be able to find Manual lockouts for it. OR TRY THIS.....

#97 of 122 4wd selector switch by grumpy77 Apr 15, 2009 (9:05 am)

Replying to: grumpy77 (Apr 15, 2009 9:05 am) Mine is a 2001 and has the transfer case motor, no locking hubs.....If yours is the same, the fact that 4 wheel high is working tells me the transfer case motor is fine. That leaves suspision with the 4x4 module. The 4x4 module needs reprogrammed or is bad. It is located under the passenger's side kickplate. You can replace it yourself, if you can find one, but you probably don't have the equipment to reprogram it. Replies to this message: grumpy77 (Apr 16, 2009 9:15 am)

Replying to: cessna180 (Jun 02, 2008 5:18 pm) Have 1998 4x4 with vacume hubs. Cant find the tool to take them off. What a really bad design. Vacume hoses need replaced and if there broke your heater takes a crap to. Wheel bearing went bad and melted the hub. Can anyone tell me where to get the hub puller for these hubs.

Replying to: fordsucks01 (Apr 21, 2009 9:32 pm) I saw all of the postings about the 4x4 and removing the fuse, did not work. The light on the dash does not go out and it is locked in low 4x4. Any suggestions ?
#103 of 122 1990 ranger over heating in the beach sand by putnumranger May 14, 2009 (7:19 pm)
I have 90 model ranger that runs fine on the highway, but as soon as you hit the beach sand the temp gauge starts to climb. I have flushed the cooling system, I have even removed the thermostat. It helped some, I was able to get down the beach a little bit more before it boiled over.

Replying to: grumpy77 (Apr 15, 2009 9:05 am) To shift into or out of 4low you must come to a complete stop, keep the brake pedal depressed, shift into neautral, then move selector switch. This is for electronic 4x4 switch with automatic trans.   The proceedure for standard shift with electronic 4x4 will require the clutch pedal depressed instead of the brake pedal.   Any trans with manual shift 4x4 generally requires complete stop, put trans in neautral, shift the transfer case into the 4 wheel mode, then shift the trans back into gear.   If you encounter difficulty shifting the transfer case into 4x4, leave it in 2 wheel and back up about 20 ft, shift the trans into neautral while still rolling for about the last 5 to 10 ft, come to a complete stop then try shifting the transfercase into 4x4 mode. If you have the owners manual check for the proceedure described there.
