Thread: Td5 Defender Clunk

lock up the hand brake and rock the vehicle back and forth as hard as you can with the tcase in nuetral. if it clunks then then its the rear diff/propshaft, the aframe joint or something associated with it. to isolate these, chock the wheels, release the handbrake and turn the handbrake drum by hand then check the uj's and rear pinion for play.


other than that its a drive line take up issue which might also include broken engine/gearbox mounts.

Cheers... i'll give that a go this arvo some time...

I would suggest cheacking your right hand rear drive member.

You probably find you know have wear in the axle flange, it is quite common with age....

So i did this and found that with t/case in neutral, handbrake off.... i had 14mm play when turning the handbrake drum.... i'm guessing this is too much considering i found no play in my mates disco... Forgive my lack of technical knowledge but i am guessing that where the propshaft goes into the diff the splines are worn... Does this sound right... if so where to from here?

Thanks once again

Hi,

depends????

do you have play in the front shaft as well??? If so your centre diff has shimes in it and they are worn. Can do it in the car with a new shim kit and bearing puller.

If it only in the rear diff, then i would try tightening the pinion bearing up a little more as this puts the load on the diff. If it lose the, the pinion gear is moving back and forth.

Try those and let me now.

to do that test you need to lock up the handbrake and put the Tcase in nuetral this effectively locks up the rear diff and lets you check the play in the suspension and the rear diff. as isolated from the rest of the driveline.

14mm of play at the circumfrence of the handbrake drum with everything unlocked isnt that bad but its not perfect.

I wouldnt go messing with the pinion nut on the diff to start with but would be looking at spline wear on the drive flanges.

there is about the same amount of play in the front shaft... i'll do some more testing of the suspension when it stops raining...

You find it will be the drive flange. I agree with Blacknight, it would be the driver side rear flange as that does the most drive for your back wheels.
