Strange knocking sound

[angelo_f]

Greetings

I was driving from Sydney to Newcastle the other day and when I came off the motorway, a strange knocking sound that sounded like a CV joint starting coming from under the driver wheel when I did left hand turn on roundabouts and corners. However, when I got home, I went out to refuel a few hours later and the car would not make the sound again. I was wondering whether it was due to driving two hours straight on morotway and something got hot. Does this sound possible or what do you think it might be?

Does it have manual freewheeling hubs? I'd assume that there shouldn't be any cv movement if you're driving in 2wd and have the hubs disengaged.

when was the last time you had your wheel bearing done?

Sounds like one of those pesky cyclists and he managed to pry himself loose once you'd stopped for a while :)

The whole front end was done about a year ago by previous owner (my brother - a mechanic) and it has not been offroad. He said he noticed the noise before he did front end. He jumped on it and did everything and could not find the noise.
CV joints have been repacked, wheel bearings done, new shocks, new sway bar. He said the sway bar was not genuine, so it could be because of that. I will keep an eye (or rather - ear) on it.

could also be loose/worn ball joints on your steering arms sometime they knock when too loose

CV make a clicking sound when you turn corners.
What you are saying doesn't sound like CV's

What are you driving by the way.

Yeah, I have had that same sound come and go. I took the trol to a mech and he put it on a hoist and we looked for a problem. The only thing we found was that there was a very small shiny edge on the front left hand brake disc. Which indicated that a stone must have become wedged somehow. The sound went away for a couple of months, but yesterday, I did a hard right hand turn and the Knocking noise came back at the apex of the turn, then stopped... Weird or what. Mine has manual hubs and both front wheel bearings have been repacked recently.

Body or engine mount?

Don't stroke it, TAP it!!!!.....

Nah, mate, definitely a rotating part. Too much grease in hub lock? But I think that would make the hub pull into lock position wouldn't it.

GQ Diesel short wheel base. I thought it sounded like a CV joint. A Clicking sound but I felt it through the floor under drivers side foot. Only when turning left

Radius arm bushes. Hard to check if theyre fine while its still in the vehicle, but mine did this when doing left hand turns. Not so much as a click, but more of a clunk. I too could feel it through the floor. Replaced all of them with genuine items, all good now. The slight steering wobble I had at about 80km is also gone now.
Mine would clunk worse in the rain when it was wet. If I was you I'd give the bushes a squirt of water and go for a quick drive to see if it made anything worse. Or just go for a drive in the rain.

That sounds very similar to my sound. What was interesting was I took it for a drive on the weekend up mount sugarloaf and went through some water, and I was sure I heard the sound come a few times - more like a clunk than a click. However, radial arm bushes were replaced already- but not with genuine ones.

[threedogs]

is it louder after you go through water ????
or more frequent if raining etc

The non genuine bushes could be the problem, they arent always as good, could possibly be inferior products? they could be fine, but theres always that possiblity.

When i do my bushes im only going genuine.

I have not driven it in the rain. However, I did not notice the sound until after I went through the water. I'll try spraying the arms and see what happens

Sorry if its a stupid suggestion, but check your exhaust mounts. I had a similar noise in a similar location and it turned out to be a broken mount. When i turned a corner hard and went over pot holes (or cyclists) too fast it would knock around.

[Pickers87]

I think that noise is common in GQs i had the same thing in mine, it came and went as it pleased but didnt affect the driving at all.

[mudnut]

I think I have traced the intermittant knocking sound to the hand brake. If it is wrenched on, it sometimes must be binding a little. After getting go juice, I pulled away from the bowser and turned to the right. The sound came back, so I pulled up and put the hand brake on. I then proceeded and the sound had gone. I went to a smooth back road, and rolled the Trol, slowly, in neutral and gently pulled the handbrake, and the sound came back. I then wrenched the brake on and off, and the sound has gone, for the moment.

[angelo_f]

It might be worth consideration. However, when I first got the sound, I had traveled nearly two hours up the motorway, so I would find it hard to think it had anything to do with handbrake. What is strange, I went out the other week and I have not been able to get the sound occur again.

I used to get an annoying clicking sound, when in my case the left front PIECE OF SHITE auto locking hub would decide to turn it self on and off, the plate that holds it all together was stuffed.. it only used to do it when it got hot, eg 1-1.5 hours worth of highway drive time took me weeks to find it as it was intermittent..

Mine has manual locks on hubs

This has been driving me nuts and every time I mentioned it was worse when it was raining I was looked at with dull eyes....... I have 2 inch with castor correction on mine but told I dont need it for 2 inch lift.

I have another set of radius arms with good rubber in them but standard offset????
