!!! Mistery $700 mistery problem and still there..HELP PLEASE!!!
hey guys
ok here it goes
my vr v6 has had a knocking noise in the front end since i bought it. when i bought it the noise wasnt so loud, but over time it has goten worse and worse and now it sounds like one of my wheels is going to fall offits a really fast "doof doof doof doof" when i turn right. it still does it when i turn left but you can hardly hear it. ive had 3 wheel bearings changed,bushes checked, brand new wheels and tyres put on and new springs. Also when i had the car up on the hoist and the typre factory they searched the car for over 3 hours trying to find the problem and they had no luck. I am very ****** off and its becoming a really expensive problem because no one can find the exact thing. i really wont it gone because its getting really bad and more annoying. If ANYONE has any theories on what it could be PLEASE share it with me.
cheers guys

Have you changed tyres front to back to eliminate tyre problem ....and is the noise there on full lock and when going fast or slow.
yea mate have had all the wheels rotated and the noise gets worse as you get faster. it becomes pretty bad at and after 60kph. even if you slightly turn the wheel the noise comes.

Have you checked your steering rack and linkpin bushes?
heard of the problem in front wheel drive cars and its usually the driveshafts. but not too sure with the commy, could be your cv's??? or ball joints? just an idea
i wouldnt know mate. i just dont wana go changing things and the noise still being there. i know its part of fixing cars but ive already spent so much on it, would be awsome if i or anymore could pin point the problem.
hey mate, have you double checked the link pins?
sorry mate
what are link pins??
what do they do
try pulling the belt off and going for a couple minute drive without the powersteering running and see if it still does it note it will be very hard to steer
also i would say check the shockers out but getting louder with speed eliminates that
Bow Down to the Emperor!
I had the same problem. A thump and a bit of a rattle from the washers. $36 and some heavy duty sway bar link pins later and issue disappeared
but surely while it was up on the hoist they would have looked at them??
they looked at everything so i asum they would ahev looked at those

the inner washer on the bottom of the link wears and the post pops through....it all looks connected but it is not and the link pin is in effect inoperative and the opposite side holds it up
TURN MY HEADPHONES UP
looking can only do so much. i could post 2 pictures of engines here and ask you to look at them and tell me which one is ****ed - not much use.
no one really spends much time diagnosing problems to 1 exact part. it's just not worth it. you get recommendations of what to replace that *may* fix the problem. so start with link pins. if that doesn't work, move onto the next part. no one can guarantee 100% that what you replace will fix the problem, so if you're not willing to give it a bit of trial and error, you won't get this problem fixed.
ye i know.
would u be leaning towards link pins or power steering like what harvz said?
I'd be checking the bearings on the top of your struts. Did they check out the front shock absorbers.
Another suggestion would be to take it to Pedders. They have a test machine that simulates a bumpy road to identify any bits that need repairing. The test is cheap - around $20 and may give you a better idea of where the problem lies.
atually now thaat u mention those bearings ontop of the struts. yea they changed them when i had the new springs put in because they were stuffed. and they said the shocks were fine.

if they had the struts out make sure the top nuts are done up tight.... and i mean tight....like take it up to snap and back it off a tad....lol....
lol yee
i was looking at pedders 28 suspension check thingy..
any1 had any experience with it??
will it find this problem?
Pedders can be hit and miss my local one is good and he would find your problem in about 5 seconds flat, he uses a big bar and flexes all the joins in the front end any loose part or knock will show up straight away. The front end on Commodores is very simple so it can't be too hard to find, but I'm not convinced it's really the front end, could be the idle pulley, power steering pump or even the harmonic balancer. If it happens on smooth road with no bumps and no heavy acceleration then you can pretty much rule out anything in the suspension
yea it does happen on smooth rodes with no bumps and heavy acceleration greenfoam.but like everyone else is sayin the link pins. it could be from when all the weight goes on that part when i turn.. the idle pulley is fine and wouldnt make such a noise,the power steering pump could be it someone was saying to discconect it and take it for a quick drive. how would i do that? its part of the whole pulley. and is there any way to check the harmonic balancer?
cheers
When the rubber in the balancer fails it makes alot of noise clunk clunk clunk but only at idle and low revs then it comes good, If you look behind the balancer (its bolted to the front of the crank) and you see any rubber hanging out or anyting suss looking then it needs to go to the bin, You can pull the belt off the front of the engine to see if it's the idle pulley or the power steering. The balancer is constant tho, anytime it's idling

Mate I would do the pedders check.Originally Posted by slappedvr
If they find nothing at least you know the front end is ok.
I had pedders work done on my VH wagon it was dear but worth it car handled well.

oww okk
i would rule out that then. when my car is idling it purs like a kitten lolz. no noises at all. im set on either the link pins or power steering pump.
what u reckon greeny?
My first thought was the link pins (bushes) also. It's easy to check them though; they shouldn't move when grabbed and shaken. They could even be temporarily removed completely for the purpose of a diagnosis.
Another possibility is the ball joint, or perhaps tie rod ends, on the LHS; the joints will wear most with the suspension around ride height but will sit in a position with less wear with the wheels off the ground. If checked in that position... The spring will also load the ball joint with the wheel unladen, stopping free play.
