Got an 89 trooper 2.6 auto trans with the manual hubs.It's a daily driver but the wife doesnt like to lock the hubs.She wants to shift into 4 like in my truck 90 2.8 5spd with auto hubs.Will a set of auto hubs fit on this or do I need to change axles?Also I've noticed that the front driveshaft will turn if i run the truck with the back tires off the ground(looking for a driveshaft vibration)Will this cause a problem with the hubs locking?

If my understanding is correct, you can simply drive around with the hubs locked in, then shift into 4wd whenever you want. It's just like having auto hubs. The downside, of course, is that you're still spinning parts you don't need, dropping your gas mileage, and putting unnecessary wear on your CV boots.

Maybe you could convince her to compromise; leave the hubs unlocked when you know you won't need them (during the summer or on road trips, for instance) and locked in when you might (winter driving or 4wheeling trips).

Actually that's not quite how an auto hub works. When you are in two wheel drive, you are not spinning the cv's.

The only time you would be spinning the cv's is if you are in 4wd. But, when you shift back into 2wd you have to back up a short distance to "unlock" the hubs. If you do not do this step you will spin your cv's until you do reverse direction enough for them to unlock.

So really there is no real wear and tear on your cv's on everyday driving with the auto hubs.

The only trucks that have wear in 2wd, are the 98 and up Zu's. They have drive flanges that directly attach the cv joints to the wheels. This configuration will have your cv's spinning in 2wd or 4wd.

Right, that's "the downside" of just locking the manual hubs that COTrooper mentioned... Just didn't clarify that this would be the downside of just locking the manual hubs instead of converting to auto hubs.

That being said, there should be many people out there that have the auto hubs just lying around rotting, unless they all threw them out... Someone should be able to send you a set. *If* this is a street-only truck, you'd honestly be better off with the auto hubs anyway, since there's really very little downside to them on the street. On the trail however, they can cause you problems because they unlock briefly when you change directions and can keep you stuck when you need them most. But if the truck never sees any trail time anyway, go with the autos...

HTH,

I guess since this is a street only truck (except when it ends up in the ditch) thats the way to go.The whole point of this is so I get my truck back.She won't drive hers in the winter.Guess I'm off to e-bay
Thanks

Check your private messages! There should be a flashing envlope up top on the left. Click it. It's up where the main index/search links are.

Thanks for clarifying that for me. I was in the middle of my morning coffee when I wrote that, so it wasn't near as coherent as I'd hoped it would be. <img src="/forums/images/graemlins/lol.gif" alt="" />

Sorry for the confusion.

ON THE SUBJECT OF THE MANUAL HUBS V THE AUTO HUBS, THE REASON ISUZU DID NOT OFFER AUTO HUBS ON THE 2.6 ENG WITH THE AUTOMATIC TRANS , IS THE TRANSFER CASE , THIS TRANSFER CASE IS A HYDRAULICALLY OPERATED TRANS FER ASSY AND WHE YOU MOVE THE LEVER FROM 2WD TO EITHER LOR H RANGE IT IS AN IMMEDIATE TRANSFER TO THE FRONT WHEELS NO MATTER WHAT THE SPEED AND YOU WILL TEAR UP THE AUTO HUBS UNLESS YOU ARE AT A COMPLETE STOP AND VERY CAREFULL ENGAGE AND DISENGAGE THE 4WD , YOU WOULD BE MUCH BETTER OF JUST LOCKING THE MANUAL HUBS WHEN YOU ARE GOING TO OR ANTICIPATE NEEDING 4WD AND JUST LEAVING THEM LOCKED , THIS TRANS FERCASE DOES NOT WORK LIKE ANY OF THE OTHER ISUZU CASES, ONE PLUS ADVANTAGE WITH THIS CASE AND TRANNY IF YOU NEED EXTREM PULLING PWR JUST PUT THE TRANSFER IN LOW RANGE IN 2WD DRIVE WITH THE FRONT HUBS UNLOCKED NOW ALL TORQUE IS TRANSMITTED TO THE REAR AXLE BUT BE CAREFULL YOU CAN BREAK AN AXLE LIKE THIS BELIEVE IT .
