Free play in freewheeling hubs

Hi all,

I've just had the transmission in my troopy rebuilt as well as changing the diff centres myself. (Detroit locker in the back and trutrack in the front)
The transmission is an auto out of an 80 series cruiser.

Since then I've noticed a harsh clunk when coming off the throttle suddenly and getting back on it.

I figured it was due to freeplay some where in the driveline. After having all that work done it was little more difficult to pin point the cause.

I got under the car and noticed there is a lot of freeplay in the front prop shaft. After removing it I confirmed it was neither from the transfer or diff.

Because its now constant 4x4 with the cruiser box the front hubs always need to be locked. I removed the front flange off one of the hubs and there is no free play between it and the axle but rather the big splines between the two halves of the freewheeling hub.

The auto box has been in there for about 200k so the drive has been transmitted through the hubs the whole time. When the hubs are unlocked the freeplay in the driveline disappears. I'm guessing they weren't really designed for this and that they have become worn overtime contributing to the freeplay in the front of the drive line.


Before I hit up eBay and get some new hubs I just wanted to ask if anyone has had similar problems with worn hubs creating excessive freeplay. Or if there is maybe something I've overlooked.

Thanks lads.
