my mates car is making a bad clunking sound coming from the front left..

- it does it most consistently when you reverse and turn to the right when applying the brakes...
- does it more when its cold than hot, ie mornings
- will also do it when hitting brakes hard and turning

upper and lower ball joints seem good, had the stub axels out completely and they feel good to the hand..
tie rod end and rack end seem ok
replaced LH wheel bearing - no real difference
upper control arm bushes seem ok

anyone had this and fixed this

there was a tiny tiny bit of movement in the bottom BJ (i think) but was hard to tell really..

how do u check the lower BJ properly?

i'm not liking the "this seems good, that seems good". it either is or it isn't. if you don't know how to do check go get on of those Pedders $28 100 point safety checks

Problem is Pedders will come back to you telling you need a new overpriced steering rack@$600 along with numerous other repairs which probably aren't required.

They will but you dont have to get it all done. Take it home and do the related bits yourself or tell them what you want fixed.

1. Jack up the front of the vehicle.
2. Place a stand under the side your checking for safety.
3. Grab a length of 50mm pipe, or strong timber, and place it under the wheel (use as a lever)
4. Try raising and lowering the wheel a few inches (several times to mimic wheel travel)
5. If you can feel movement, before the spring creates resistance, you've got a worn ball joint. You'll probably hear the clunking noise as well.

At the same time, you can try moving the wheel (3 o'clock to 9 o'clock) to see if there's any movement in the tie rod joint.

Put the Jack ( decent trolley jack ) as close as possible to the wheel under the lower control arm. Jack up the vehicle at that point, till the wheel is off the ground by about 3" or 4". Use a crow bar under the wheel, move the crowbar up & down, as well as sideways.
You may need another person with a torch to see whats going on while you are moving the crowbar.
If ANY movement is detected at the ball joint, it is defective.
The lower B/J is the one with all the load on it, the top B/J just holds the wheel upright.
The most accurate way of checking any suspension component is to check it at ride height...thats where most of the wear is.
If you check it at full hang.....your not checking it at it's wear point.

Need to go get in your hug box huh? i was having the same problem except it would clunk when hot (and really bad after a few hundred K drive) changed upper and lower ball joints and tie rod ends (boots were gone) as well as sway bar bushes and re attached my front bar properly (clip had gone walkies again) and now its all good - althoug when i had the wheel alignment done they recon the th front left needed 8mm more shims than the right side, and that heavy towing and spirited driving can make the front of the chassis go a bit wonky
