Strange noise from transfer case ... any clues??

hi guys - any clues as to what this might be -I put a screwdriver up to the transfer case and the noise seems to be coming from there (2008 JKU Auto Petrol). Well, i tried several spots with the screwdriver and this was the loudest spot.

The rattle/knocking sounds seems be occur once per wheel revolution.

Yes, the boot on the front driver shaft is worn / slightly ripped, but it not touching / fouling anything at this low rev speed.

The Jeep is in 2H with the front up on axles stands, allowing me to rotate the wheels by hand.

If this is a stock driveshaft it could be your CV joint is shot.

thanks for the response. yeah, it's a stock drive shaft. what is it they say about Jeeps -- Just Empty Every Pocket -- oh well, another weekend project for me LOL. local guys here reckon replace it with a Tom Woods - about AU$700 plus fitting (which i believe i can do myself)

Let us know what the outcome is . good luck.

I'm assuming your in Australia? If I recall they are super strict about lifts and keep you below 3" correct? I would save your money and buy a used JK drive shaft from another jeeper or junk yard. Stronger than a 1310 and a ton cheaper!
