hub & tire questions

[Slim Teufel]

When I 4x it is only when I enconter ice/snow during visits to Ohio, when I need to visit undesireable locations on military installations or when I drive on the beaches of the right coast. Would manual-locking hubs benefit me?

Stock size tires are 265 75 15 for my 91 How much larger, if any would 31 10.5 15's be in comparison?

How much fuel mileage will I lose using tires like BF Goodrich Mud Terrain's? I am getting 15/19 city/hwy currently.

As a preemptive measure: 'cause I am new to this.
Dollars to doughnuts I have forgotten more about troubleshooting 'puters than you will ever know.

Early models up until around 97-98 have manual or auto hubs. If you have these, manuals are more durable, but if you dont use it much what's the point of spending the extra money on it.

If you have a late model with drive flanges(front axle turns all the time) you'd save some gas with manual hubs. Also save wear and tear on those CV boots. You'd loose SOTF though. Look here for a how-to http://www.4x4wire.com/isuzu/tech/manualhubs/?

Thanks for the link, Chris. It explaind a lot.

Does a 91 Trooper have drive flanges?

stock auto hubs sucks. mine were on their way out when i bought my 91. i just got a 90 and i think they're in better shape. when they start clicking and grinding the end is near. i say if you do use 4x4 alot, then its worth it. even if you don't do any hardcore wheeling. its nice to know when you turn the dial its locked and theres no bones about it. installing manual hubs is very easy. the hardest part is the damned c-clips.

the drive flanges has to do with shift on the fly i believe, 91 troopers don't have that. 31's can fit on a stock trooper, but it will decrease gas milage and power. i'd say bfg mudterrains arn't that bad of a gas killer compaired to a tsl swamper. but not sure how much it will effect the milage. i never kept track of that stuff with my truck.

Thanks for clarifiying that.

The hardest part about the whole swap from auto's to manual's is definitely removing the c-clip from the auto hub. It's recessed in the hub and hard as hell to get it off. After that it's a piece of cake.

when i was doing my hubs i failed to find an indept picture filled article on how to swap the hubs. i saw articles at the wire for the shift on the fly, but not the standard hubs. and with my superwinch's it made things a bit difficult.

if your truck is 95 or older get these:




hands down the best lock out hub out there for Isuzu....or any 4x4 for that matter

That's my wifes daily driver you're talkin' 'bout, Willis
It's a '94 Trooper.




and, as if I don't have enough projects on my plate,
*whispering*
I'm hoping to take delivery of an RS sometime this month

The one thing you can do if you have manual hubs on a 90 is if the hubs are already locked you can shift to 4xhigh range on the fly. You can do this cause both side of the tc will be turning at the same speed. With auto hubs you have to come to a stop.

You can do the same thing with auto hubs if they're locked. i.e., instead of getting out to lock the hubs, stop, shift to 4wd, go, then shift to 2wd after a few feet. So long as you don't reverse direction, the hubs stay locked and you can shift in and out of 4wd on the go. Manual hubs are better though.
