Hi all my new 80 series seems to have a couple of small problems I hope. I have a clunk in the drive train somewhere. I think its the front diff. It happens when you let the clutch out quickly you get a clunk and a jerk in the driveline it also happens
well you take your foot of the accerator and the put the foot down quickly again this happening when cold or warm. Checked the front drive sharft there is a quarter of a turn of play in the front diff. Can anyone help

Tim.
Sound correct.
I have a 94 petrol GXL that is the same, The front diff gives the most backlash. If you rebuild the front diff the clunkiness will reduce but not totally. Being constant 4wd the total backlash comes from: Front CV's, front diff, Driveshaft splines?Uni's, Transfer case, gearbox and rear diff. When this is all added up the backlash is quite a lot.
Some people have converted back to 2wd and naturally this makes quite a difference.
All The Best
Greg

Tim,
A 1/4 of a turn is too much on your front drive shaft. It should be no more than 1/8 at the most. I think you will find that your diff and axels may be on the way out. With that much movement it means the splines on the axels and in the diff have worn away (to a point - instead of being flat on top) giving too much play. If this is the case it will require the diff (which is a Hilux diff) and axels being replaced.
I know this because
mine had too be done in Oct 04, cost me about $2000 all up - it had to be done. The back lash has improved, but with the constant 4WD it will always be there so I am saving up to fit on of the part time kits.
Hope this helps and best of luck.

Tim,
Always take an interest in any posts about 80 series, as we have a 97 model with 243K clicks on it.
Today i got underneath, and checked freeplay in front driveshaft, and it is less than an 1/8 of turn. While ours is a bush vehicle, much of its life has been on long trips, usually with cruise control doing the work. Rarely do much city driving, reckon that would be the place to increase wear in splines etc.
Hooroo...
