Interesting reading from SPAZZ to me about hubs and stuff...

......
IF YOU ARE 4 WHEELING when you have transfer case shifter in HIGH it uses TOD...when you have transfer case shifter in 4LOW all 4 wheels crawl. You should use 4LOW for control..TOD was meant for fast speed driving, but works in some slow situations.

Our stock hubs ARE LOCKED all the time. Makes em wear out way faster than if you had to manually lock them in.

When Manual hubs are in FREE it does not allow the TOD to send power the front wheels. It tries, but it can't, so you don't have to waste that gas it takes to send power to turn the front. You don't understand the whole saving mileage issue???...then just think about how much gas you use in 4WD and how much gas you use in 2WD on regular autos...a big difference.

so, if you had Manual Hubs and you just did normal everyday driving, put hubs in FREE to save gas mileage and wear and tear

if you go offroading, put Manual Hubs in LOCK and you could either keep transfer case shifter in High and use TOD or in 4LOW to have all 4 wheels crawl

same concept if the weather gets bad and you would just put Manual Hubs in LOCK and you could use TOD.....

as for a TOD on/off switch...that is not hard..you just have to install a switch of your choice and tap into the TOD wire I believe located either beside drvr or passenger side seat...
in this case ou could disable TOD for total 2WD to save total power sent to front wheels by the TOD...comes in handy if you break a cv.

there is 2 types of hubs for us

a) AISIN
b) Super Winch

AISIN hubs are stronger than Super Winch and more expensive. AISIN hubs can be found in junk yards or buy brand new... on any ISUZU with a 17 spline axle and same 6 bolt pattern that our hubs now. I posted pics in my gallery, check em out.

if you get the AISIN hubs from junk yard..I got mine for $30..not each but for the pair...that is $30 total price to me for a pair of AISIN Manual Hubs. be REALLY careful taking them apart...

easy tip...

1) put the AISIN Manual Hubs in FREE to retract the spring inside to the outside portion of hub...if in lock you will have to deal with some issues that you could just prevent

a) 10mm socket to get these 6 bolts off...might take some force but a hard hit to loosen will usually work...DO NOT OVERTIGHTEN THESE BOLTS...if you turn the wrong way or force these when tightening they will twist off in the hub and difficult to get out. Once out side portion is free, just pull off.

2) Snap ring pliers to take of snap ring...be careful to get the spacer ring or two behind the snap ring...easy thing is to lay outside piece you took off 1st in safe clean dry place and lay snap ring and spacer(s) on it...

3) next a allen head is needed...same size as the bolts holding your front drive train to your pinion flange on front axle. Remove these 6 bolts and then remove inner portion of hub being careful not to allow guts to fall out...easy thing now id to put snap ring and spacer(s) inside this inner portion, put 6 bolts in holes, and the put outside portion on and screw outside 6 bolts in...this will hold everything together and you can transport them safely...

if you want once they are all off and you have them in together holding all pieces...rub them in some greasy mud to amke them look worse than they did...that way you might get them cheeper..if you bring them out of the junk yard looking all pretty and clean they will charge you more......
