Hi guys I have noticed a knocking noise coming from what seems the right front. Noticeable when turning left and is agrivated by braking. It only makes a single clunk some times very loud. I have checked all the bolts and the ball joints look ok . I can't see any spots were there could be rubbing. Any ideas?

Ball joints would be the first ting that I'd look at and even though they seem to be OK on purely visual inspection, this may not be the case. One needs to jack it up and check for play with a tommy-bar.

The other thing I would look at is the shock mounts top and bottom, and if it's a strut make sure that the upper mount is secure.

Could be, but a single 'clunk' is what Justin described and CV's will mostly make a series of 'clunks'.

Does the sound still manifest when stationary and turning the steering?

CV. Usually start of with clunk while turning. The badder it gets it will clunk-clunk-clunk worse while turning.

Another option might be is when one had brake pads replaced or work done in the front some one forgot to torque the damn caliper bolts.

Your hilux 4x4 system doesn't disengage the front diff, the hubs are always locked so the cv are always turning when driving in 4x2, to test find a patch of grass or gravel and engage the 4x4 and do some tight turns while accelerating and see if you can hear a clunk clunk noise then you will know if it is your cv joints.

Hi guys. Thanks for all the responses. I don't think it is a CV joint as the noise is very clearly a single clunk. I can actually feel it in the floor when it happens. I have been underneath again and there does not appear to be any loose bolts or nuts and everything looks to be in the correct place. I don't feel any excessive play anywhere. There is a small amount of play in the steering rack. However not enough to make the loud distinctive noise I am referring to. If you turn the steering to check for free play in the rack there is non. One can also hear it though not nearly as loudly if you reverse turning left or if you bracket sharply at love speed.

A quick way to check the ball joints. sit next to your tyre, place you feet firm against the bottom, grab the top of the tyre behind and give it a good pull. you will see if your ball joint is failing, the tyre will move.

All the ball joints feel tight when testing.

The only other thing to do is stand out side and look at the wheels when someone is driving your car and try and see if you see anything happening to the wheels , any side way movements, open the bonnet and look inside, checking the shock mounts . maybe jack the front of the vehicle up onto stands so that the wheels hand free and try look and feel for any lose parts without any weight on the suspension.
