Knock when reversing and turning

Every time I reverse with full lock on I get a single knock when the car starts to move. It sounds like it's coming from the rear of the car. If I reverse in a straight line I don't hear the sound. It's not the sound of the slack in the drive train being taken up when reverse is selected but it happens as the car starts moving.

If I reverse with the wheels straight the knock doesn't happen until I turn the steering wheel about 1 turn.

There is only ever a single knock each time, but if you go forward again and then reverse again it will happen again. I've got someone to stand near the car to listen for the noise but it's hard to tell since the car is moving.

jack one front wheel up and see if you can slowly turn it with a socket and bar ,box in n

As above plus check the UJ's. When did you last grease them?

Just did the test and the V/C is good.

UJs were greased less than 10,000 miles ago, probably much less than that. I greased them again now anyway but I haven't drove it yet.

If they are knocking grease is not going to do a lot of good.

UJs changed today, still get the clunk/knock. Any more things to try?

After a bit of searching I found this TSB about clicking from rear axle. Some people on another forum seem to have had the symptoms as me and the solution was to follow that TSB.

I'll try it when I get time and report back.

Good spot. Superglue? Sounds like a bodgit.

Be interested to hear how you get on.
