So as the title says my 99 th wagons front passenger wheel starts squealing with each rotation of the wheel while driving it starts at around 30-40kms and gets faster as i drive faster however when i start to go over 100kms/hr i start to get violent vibrations or shaking through out the entire car if i maintain speed between 100-120kms and the squeal is still there, if i go faster then 120kms it stops shaking and the squeal disappears, any suggestions would be great at the moment im thinking of replacing the wheel barrings, possibly a tie rod or the cv joints?

Wheel bearing I'd reckon. Never done one in a Magna though... If it's that bad it sounds of metal on metal it's probably not safe to drive until you properly identify and fix.

CV joint?

It could be front wheel bearing, but first check the condition of your front brake rotors, if it looks like an old 70s vinyl record every chance the rotors are warped, you will get squeak and vibration from that

i start to get violent vibrations or shaking through out the entire car if i maintain speed between 100-120kms and the squeal is still there, if i go faster then 120kms . . .

. . . any suggestions would be great at the moment im thinking of replacing the wheel barrings, possibly a tie rod or the cv joints?

So you go over 120 KPH just to "check" what it does? Are you expecting speed to somehow fix the problem?
What if it is a dead CV joint or wheel bearing that lets go at that speed? Rather you than me!

Would it not be slightly smarter to jack the front up, (preferably at a speed of 0 KPH) and have a LOOK at what is going on?

I'm guessing it is a combination of dragging caliper or dry CV joint (the noise) plus worn ball joints (the vibration), but I can't quite see your car from here . . . so that is just a guess.

Check:
Disc brake - seized caliper, warped disc, worn out pads, or a combination of all of these.
Wheel bearing for play.
Tight/damaged CV joint.
Worn ball joints.

If you don't feel qualified to diagnose this, take the car - slowly - to someone who can.

thanks the help, pads are fresh about 3,000kms ago, calipers work perfectly and the disks aren't warped so brakes are fine, i didn't go over 120km to see if it fixes it i was only trying to replicate the problem between 100kms - 120+ see if the vibrations stop turning left or right or going over a few humps and trying to listen exactly where its coming from but no change, iv also done the basics as in jack the front of the car up and turn the wheel but no squeak or scrapping noises just the brake pad light touching the rotor which is normal, so might just replace the lot to be safe but with all things considered she is at 647,000kms so have to expect something to wear out, but other then that shes still going strong :)

647,000kms!

Any history of ball joint or drive shaft replacement?

Yeah mate should be a free upgrade to a 380 if you hit 1,000,000kms :D ill have to post a pic up

im the second owner, first owner was my dad both ball joints and drive shafts have been replaced twice both sides done at the same time in its life
