Hi Can anyone give me any info on how to check the chain wear of an 2001 prado kzj95r
without removing the tranferbox and pulling apart. Is there a measurement that can be done to measure the back lash between the two drive shaft flanges to give an indication of the wear in the chain. I have a clonk when ever i coast and that put the power back on.

I cant recommend you do this, but this is the tell tale sign of transfer chain wear

Try taking off uphill applying slightly more gas than normal (as in a speedier takeoff). There should be a loud clunk. You can try putting th transfer in LL (4Low) and taking off the added torque will make the same noise. There's no way a ujoint can make that sound without you losing your driveshaft or vibrating heavily when running normally..

If you have that clunk then there's absolutely no doubt you need to change your TC chain. Oh, and I wouldnt leave it for later on, If your chain is too worn it might skip a tooth and basically kill your transfer case!

Can also be a panhard rod bush, they make a clunking noise when worn out too, when you power on and off.
