Drive Shaft/Tail Shaft

    Gday all...

    Quick question: Is there the potential for any damage to either the transfer case and/or front diff if I remove the front tail shaft and continue driving the car?

    Car is a 100 series cruiser...

    Reason I ask is I want to 'feel' the drive of the car before I think about getting a part time 4wd kit but don't want to risk any damage to the components of the 'full time' set up in the cruiser... and i spose the easiest way to test that is take the front tail shaft off and drive it around for a few days....

    I think it should be fine as I've been with ppl who have taken in off when there've broken something

    You would have to lock your centre diff.

    Otherwise there is no reason why you can't do it.

    why do you want to do the part time mod. most of the time its only done if the centre diff is buggered and its cheaper to do after market stuff. the all wheel drive offers you the identical abuility off road with cdl in as a part time with hubs locked. and when not engauged you have the added advantage of all wheel drive in rain etc on a hard road where a convetional part time 4x4 cant use 4x4. you have the best of both worlds now . why give your advantage away? In bad weather on highway situations you will regrete your choice to go part time 4x4 mod. My all wheel drive was a huge advantage living in darwin with water often all over the road . it was also fatastic for black ice on the road while i was living in wadonga nsw. Its crazy to give that safty up.

    I find I'm agreeing with you a lot!

    Can I ask why you'd need to lock the centre diff mate?

    Don't get me wrong... I love the fact I have full time 4wd - what I don't love is the amount of play in the transfer case and box, along with the wear n tear on the front end..
    I just wanted to feel how the cruiser runs in 2wd, that's all, and didn't want to damage anything by removing the front tail shaft and driving it for a day or 3

    Cheers for the replies.

    If you remove the front drive shaft and don't lock the centre diff you won't go anywhere. ;)

    It will just try and drive the shaft that's not there as that will be the path of least resistance.

    No different to a normal open diff. It's just front to rear not side to side.

    I have found extensive play in lots of 4x4 that owners thought it was a new tcase required. The first thing you should do is rebuild swivel hubs and replace ever single universal . (90% of the time this cures backlash /play problems) I have been at the other end of a cranky customer that was perswaded by some one else to do the part time trick only to find the back lash was still there he felt quiet ripped off , a few universals and swivel rebuilds along with 16 new swivel studs was all he needed.

    I agree with Muc.
    I had my 80 series fitted with the avm part time kit about 4yrs ago and wish id never done it.
    The 4b feels alot less stable especially on wet rds and on general dirt rds where I now get out to lock the front diff in to regain the stability and sure footedness offered by a full time 4wd.

    I also have a 100 series that is full time and the difference is remarkable, the 4b feels alot safer on all rd surfaces and ( maybe im getting old ) but I don't have to get out to engage the front diff.

    People say you get better economy from the partime kit but it's very marginal, they also say it reduces wear and tear on the front driveline but the 4b was designed to be full time, by taking that away your sending all the driveline stress to the rear, sure it can handle it but overall your 4b will be better for it in the long run keeping the full time 4wd.

    Haveing a part time kit fitted to a full time 4wd is taking a step back in time and technolagy in my opinion.
    This is just what iv experienced from both my trucks, im sure people that have had the kit fitted will have a different opinion to mine but for me, go the full time any day of the week.

    Cheers Mac. I might try that first mate.

    Is there a specific brand of uni i should look at? or go Toyota?

    People often wondered how i could sit on 100kms per hour in my v8 allwheel drive discovery on corrigated dirt roads in the NT. The were compairing there 4x4 to mine . Its a pity it took years for toyota to bring this allwheel drive feature out because its what robbed them of the 4x4 reviews when up against the defender and discovery off road long distant driving for a decade or so before.
    If you have ever drifted off course from corrigated roads your not in all wheel drive and you need to slow down. Its amaizing how much differece all wheel drive makes in the dirt and even snow. My allwheel drive never gave me any trouble in the six states i traveled in . I cant understand why there is even a market for part time kits for landcruiser. Oviously led by landrover haters making out you have to be old school toyota part time 4wd to get anywere. Aparentyl beleiving all wheel drives are all soft roaders and the weak link in a toyata drive line . Thats not the case. there is no logical reason for wanting a part time kit for the landcruiser . the money saved in fuel will never amount to the cost of the kit in the remaining life of the vehicle. Its a loose loose situation.

    cbc bearings will have Hardy Spicer its all i use ask for the greasable ones .
    The non greasable are actually stronger but do not last as long as they are not serviceable . Remeber the old saying . Grease and oil change ?

    Most people forget the grease bit when they change there oil.

    Gday fellas...

    I have replaced all 4 uni joints and noticed about a 30% decrease in the backlash.
    Thinking I'll stay clear of the part time kit...

    Cheers for all your input.

    Yep im one of the suckers that got convinced the part time kit was the way to go.

    After having it in my 80 for 4 yrs now I regret having it fitted, the 4b feels alot less stable on dirt and wet roads, ya gotta get out and engage hubs, the fuel savings are very minimal and all the work is now done by the rear diff where as before the work load was shared front & rear.

    It's old technolagy.

    My 105 series is still full time and much more sure footed, a pleasure to drive.

    awesome , glad its worked out . a little backlash can be reduced some times by periodicaly checking the shim clearance at the front axle flanges. it should be no more than zero-0.3 of a mm of play. if therers more the front cv joints wear out the axle drive flanges and cause axle backlash.

    Biggest reason for the part time kit is for more hardcore 4x4ing so you can fit auto lockers and also if when going hard and you crack a cv you just flick out the hubs and go home or keep going in three wheel drive
