Clunk noise on reverse

[fourteen8]

Clunk noise got worse when putting the gear no reverse (auto gearbox) yesterday. Always heard the noise but yesterday got worse only. This morning wasnt so bad.

Is this normal? Is it time to change the automatic gearbox oil?

with the wagon on flat ground and in netural and hand brake off get under the wagon and turn the prop sharfts back and forth a little and see if either have a lot more movement then the other

Time for a very CLOSE inspection of the propshaft UJ's imo, in particular the front UJ's in the hookes joint (double joint)

Probably the UJ's - mine was teh same problem and became a "tweet" noise also. Purchased two greasable UJ's from a bearing speclialist for less than $50 - a Hardies product I beleive?

Fitted by a mechanic or can be done yourself is you have the gear..

It may also be lash in one or more of the centre or axle diffs.
