ok as some of you might remember my car spun a drive shaft abouit a month ago now,
since then i have replaced both drive shafts and the half shaft (it was the half shaft that was buggerd)
anyway ,
now when ever i turn to the right while driving, the car makes a clicking and clunking sound
from the drivers side front.
but when i jack the car up and turn the wheel to the right and spin it by hand it doesnt do it..
ive checked the cv joint boots and they are fine
checked the pads aswell because i thought they might have been grabbing on the calliper
but they are fine also.
the car will drive fine in a straight line and when turning left,
it only does it when turning right/
any input to what i should check or what it might be would be a big help
thanx

Check that the rotor isn't rubbing against the dust guard behind it mine was doing this earlier after upgrading brakes
Hmmm, the dust guard moves around with the rotor so if that was the cause it would be doing it in a straight line and as well as turning left. It might be the inside edge of the tyre rubbing around against the splash shield..
Tyre rubbing up against something else maybe? Park it at full lock and have a feel see if anything is touching.

i think i found out what it is, THE DIFF, i had a mate sit in it and slowly drive forward at full lock while i was looking under the bonnet and the whole engine jumps up and down when it makes that noise , only happens when i turn right probably from the extra load on that side of the diff
Check the engine mounts out :)

could still be a CV joint , getting jammed at full lock. a diff would do it even at smaller turns , or anytime there was a difference in wheel speeds.
On Commodores if you adjust/instal the tierod on both side without first centreing the rack, you end up with the wheels making a sharper turn to one side...in the extreme you can, for example, be only able to turn the wheel to the left one turn, but to the right maybe 2 turns....and this in turn causes the wheel to foul the body...in Commodores that is. Translating this to a Magna with identical steering design, the result could be to force the CV joint to assume an angle for what it wasn't designed for on full lock....and then it will clunk and rotate erratically not as a constant velocity joint but more like a Cardan/hooke's joint. Just a thought.

Sounds like more a CV issue, did you get brand new shafts or secondhand ones
The Diff could be the issue as one wheel will be turning faster than the other being on full lock but depending on the answer of the above question I would not jump in and point at the diff

hi mal
i got the shafts out of my old magna , i just swapped them over but they were fine in that car.
i had a look under the car when its driving forward and when it clunks the whole drive shaft jumps up and down.
and the faster you turn the more violant and loud the jumping is.
but again only does it after you pass half lock when turning right.

CV joints are gone.
Drive, gently in circles. First Clockwise listen for the noise.
Repeat anti -clockwise.
Reconditioned shafts aren't too expensive.

Which end jumps the most? Could be a CV problem, wheel bearing or diff problem. If you know the CV joints are good, it has to be one of the other two possibilities. Grab the offending shaft at either end, and give it a good wriggle and turn the road wheel slowly while the car is in right lock (wheels off the ground). You should soon locate the problem area.
Loose driveshaft retaining nut? (260 Nm) Worn splines inside the hub?

its hard to tell which end jumps the most , when i had a look the whole bottom of the engine was shaking up and down not just the shaft.
turning clockwise like gerry said it makes a noise and a clicking like something grabbing then letting go and grabbibg and letting go it will kepp doing that aslong as the car is moving , anti clockwise nothing
i grabbed the shafts gave them a good wiggle and no play in either of them.
i got the right wheel off the ground and turned it full lock and spun it by hand and no noise or anything.
the half shaft that i pulled out , the spline things on the end that goes into the gearbox wernt broken , it looked like they were grinded down.
splines inside the hubs are fine , wheel bearings are fine,
im thinking something inside the diff is broken and is slipping around the teeth on the half shaft causing them to wear away???

Is strange however that will do it one way and not the other if is the diff
I would also forget the reco shaft option as these often do not have a very long life at all
Is sounding more diff but first I would put the old shafts back in if you can and try that, if still same then is diff, if not then you have found the issue

half shaft was stripped so i replaced it and it stopped the grinding noise , so i took it for a drive down the road...
then turned a right corner and the clicking and shuddering was still there
so i pulled the half shaft out and it had also been stripped but it was fine when i put it in .
my conclusion is that the splines in that side of the diff are stuffed so ive enquired with madmagna about a getting another half shaft and diff .
very frustrating but hopefully will be bac on the road soon :)

Same issue here but in my case when turning left, coming out of right hand side of. Now i know where to look.

You can actually see the mating splines in the diff once you pull the shafts out and visually check their condition IIRC. Your gearbox will be contaminated with metal from the half shaft etc and would need to be opened up anyway for a clean out. Might be easier to get another gearbox and avoid any damage done by bits of metal floating around inside the current gearbox.
You might want to reconsider your driving style to avoid this problem happening again. lol Any ideas on how this happened in the first place? (So I can avoid doing the same. lol )

yeah i cant really afford another box at the moment , i have no idea how it happend... like i said in another post i only had it for not even 2 months before this happend.
im a sensible driver i dont do anything silly :) when it happend i was turning a right at an intersection and it sounded as if something snapped.
im sure it wasnt a result of my driving style though.
