Desperate need for advice

[charliep1982]

Hi can anyone tell me what has happened to my v6.
Since purchase earlier this year, I have been doing tinkerings when finances and my beloved allow. So far have replaced alternator and started the audio visual install.
Now to the issue currently sending me potty. I have noticed a developing clunk from the front (possibly nearside) driveshaft area. When I bought the car I was told it had recently had new driveshafts on it so I doubt it is that. It could be a bush issue. But I am not 100% on this. It is quite a vicious crunch when braking in reverse and a general knock when travelling forward. I have recently discovered that the locating screw is missing from the brake disc but this should not be to much of an issue because the wheel bolts hold it all together (don't they?) Any ideas will be taken as gospel and will be checked thoroughly. If I can tell her indoors what it probably is then she will give me the chance to fix it otherwise i have been told it has to go. HELP ME!!!!

1st place i'd look is the wish bone bolt that go vertivally through the subframe, they have to be stupid tight.

[charliep1982]

Thanks will have a look at that first

[stevo turbo]

also check for play in the anti roll bar bushes or drop links. just grab the bar and push back and forward + up and down. if you feel ANY klunking or knocking (in movement terms not sound) its one of the two. just see where the play is

[calibra_steve]

could always be a gearbox mount as they make the sound travel aswell

as your driving along it will make stupid knoking noise and breaking hard the engin and box could be moving forward enough to hit somthing....
iv had that problem lol and it was my mount lol

[v6 steve]

if the cv joints have been done i would check the hub nut as it has to be well tight, i would also do as Cally man has said the subframe bolts have a way of working loss best put some lock tight on them

It is quite a vicious crunch when braking in reverse and a general knock when travelling forward.

what sort of speed are we talking about here? direction of travel? straight or curve? constant knock, random, or depends on road speed? severity of bumps?

So to recap all answers at the moment (plus some extra).....

check the lower arm ball joint to strut,
track rod end to strut,
driveshaft nut to hub,
antiroll bar drop link to lower arm,
upper strut bearing (suspension turret) jack up the car to check the spring isn't broken too,
all three subframe bolts on the passenger side,
brake caliper bolts (10mm allen key)
brake caliper sliders (7mm allen key)
brake disc securing bolt (yes I know its missing but put one in to be sure)
front gearbox mount to chassis leg (bolts into g/box and chassis leg)

If all those bolts are (F) tight the you'll have to start looking for worn rubber mounts

[charliep1982]

In forward gear it is a constant knock more noticeable on decelleration.
In reverse when braking from any speed it is quite a bang

[v6 steve]

have you checked the stuff that we have already said? it might be worth looking at the torsion bar its on the left hand side of the engine just under the air intake pipe, it joins the engine to the inner wing and stops the engine from pulling back under accelartion

[charliep1982]

Unfortunately due to my baby being unwell I have not had opportunity to check it yet. I am planning to look tonight weather permitting

[MarkSE7]

It'll probably be the lower arm bush has seperated at the back of the arm where it bolts into the subframe.
It'll constantly knock while driving and make a cracking noise when pulling away and braking. Stick a new arm on it.
Mine has had a new arm in the last 18 months or so but the bush in it has come adrift and I get the same noises.

FOUND IT!!!!!

I have got to say I was mortified. The previous owner either took this car to a total cowboy or was a poor DIYer the bottom retaining bolt on the nearside caliper is completely missing plus the brake disc has about 8mm of play any ideas where I can get cheap replacement parts for it?

[Callyman]

when you say 8mm of play, what do you mean?

[charliep1982]

I figured that out it was just where the disc locating screw isabsent the disc is loose on the hub

[BazV6er]

so you only have the one screw from the caliper holding onto the brake disc , i guess that would make a loud clanging noise and probably work the top bolt loose .
