Replaced the U/J's on my front prop last week and noticed a sizeable amount of rotational play on both front diff pinion and transfer box output shaft. Gives me a klunk if i let the clutch out quick. I'm not too bothered by it but...
Question, what causes this amount of play, what is worn and what can I do to remove it ? I'm being specific here so I'm hoping I'll get more info than just a new diff or transfer box.
Cheers

try ramming a dislocation cone between the prop and the transfer box casing to take up the slack - that might do the trick.

See told you they were good for something :lol: :lol:
Mace,
Someone will be along soon to give you a sensible answer :lol: :lol:

I dont think Andys talking to me anymore :cry:

On the Diff it could be anything from excess backlash on the bearings, worn splines on the diff or driveshafts through to worn teeth on the ring & pinion.
It may also be worn splines on your wheel hub drive flange or play in the CV joints. :?
As for the transfer box, sorry not up to scratch on those so your guess is as good as mine! :D

I have exactly the same symptoms as yours and was told it
could also be the gearbox output shaft splines so
my thoughts are wait till it goes wrong then fix it :D :D

Bobtail, with those problems then you'll normally get the dreaded "Clunk" from the rear of the gearbox as you lift off the clutch.
If you fancy prolonging it a bit then you could fit a new Input gear (http://www.ashcroft-transmissions.co.uk/part_32.html) which costs about £45, fitting instructions on the Ashcrofts website and will remove 50% of the play cos half the splines will be new!! :D
Like I say, it's only prolonging it if there is already ware but it may last until after you sell the vehicle! :wink:

You've obviously not been paying attention...they are RE-location cones :wink:

Budgie, didn't think it would be simple but with so many variables it's hard to know where to start. I've also got a whine from the diff at speed so I'm not that confident it's not ALL of the above :lol:
Anyway, long term I was hoping the diff would last so I can rebuild it at a later date with new ratio crownwheel and pinions to alter the gearing. But you know how it goes, £500 on a re-build then the gearbox goes and you ain't got the cash to fix it. It maybe worth a simple dismantle, inspection and refit just to find out whats got play in it. Short term solution to a long term problem I'm afraid.
Is there a simple TEST that can be done to check part components, for example jacking up one wheel to test for play in the half shafts, cv joints or the like? I might be able to eliminate something this way.

You can pop the caps off the axle drive flanges and have a look at the movement on the splines to check that one but apart from that there's nothing else I can think of without removing the diff & the halfshafts. :(
You need that No1 eyeball to sus out which parts are worn and, with so many in the chain that it could be, there is no way to tell with out removal.
Jacking the wheel will only tell you that there is play in one or more of either the R&P, any one or more end splines of the halfshafts, C.V's, stub axles or drive flanges. :?
Sorry, it means work if you really want to find out!! :D
