Good Afternoon
In an 80 series Cruiser (constant 4WD) how much movement is normal in the two drive shafts? By movement I am referring to grabbing the shaft and trying to twist it by hand. What does excessive movement indicate and what is the fix?
Thanks in advance from The Moose.

Hop down to a dealers show room and check some of the new vehicles. I think that you will get a surprise !

Long time since I checked
mine, but I think it was around a max of 1/8th of a turn.

Man that's massive play tolerance! I checked
mine during my last lube up, and it would have been less than half that and
mine has done 280,000kms.
Looks like i'll be good to go for another 280,000kms ha ha.
Moose, if you are concerned, i'd drop in to a transmission specialist or a 4WD repair center and get them to give it a twist. Tell them you are preparing for a 4WD trip next week and want to know if it will hold out. At least then they wont try to sell you a 4grand trans rebuild and give honest advice ha ha.

I get
mine serviced by a 4WD specialist, and he thought I was mad because i insisted on replacing the universal joints & splines just because they had a huge amount of slop. My concern was that they just make a lot of noise and I'd sooner pay to get them replaced where i choose the mechanic. He reckoned they were a long long way from breaking (at 250 K).
Normal seems to be heaps.

Its good to do preventitive maintenance, and replacing unis can be a good idea anyway. But replacing yolks which may not have excessive wear could be money saved i guess.
But if yours was noisy (giving a "ting" every time you back-off, or shift into Drive or Reverse) then that would probably drive me to getting it looked at too- as it would be pretty annoying.
Mine is still tight and quiet.. so far...

Tippa - you got it. Lots of "tings" and "tongs", and not surprising since about half its life its dragged a tonne of camper trailer or 1.6 tonne of caravan!

There can be a surprising amount in a constant 4wd, your handbrake is out by the
wheels so you have any play in the rear diff, play in the centre diff, transfer and transmission, and the front diff and CV's.
I usually check with it in gear, handbrake on and see how much it moves then.
Try to see if there is any sideways movement in uni's and pinion and output flanges as
well. Any sideways movement however minor is not good.
A damp or seeping seal can be an indicator of excessive wear as
well.
If there are no "tings" etc on takeoff then all is probably ok.

Check for play where the drive shaft comes through the hub. Where the free wheeling hub usually is on the front
wheels. These splines do get excessive play and when they do they cut the splines out. You then lose drive.
When this happens you are able to drive in four wheel drive low range with the central diff lock engaged, Or if you are one of the sneaky people that has modified the electrics in high range with central diff lock engaged.

Oooohhhh.... you got me thinking! I suppose then that a switch could be fitted which locks the center diff at any time....
mine has an limited slip center diff which locks in low range only... for now heh heh. Now to search topics.... :)

LOL...Yeah there is a modification you can do so it locks in high range as
well.

Mate,
Toyota have the best uni joints in the business and as long as they are greased you will have no trouble, if you are getting a clunk on taking off or slowing down then made it's time for some tlc. Spline wear or preload on the pinion
