steering bushes / rack are apperently fine, 2 mechanics have looked at it , i wouldnt know a thing about it myself

i can't see any evidence of acidents and i'm sure suspension places or mechancis would have pointed it out as the easy way out of a question by a customer (should be easy with the car on a hoist which they have had it many times)

i went to swap my friends r32gtst 4's wheels to brothers r32 gtst just yesterday. turns out that suspension components must vary greatly between these two cars, as there was insane scrubbing with 18's on the gtst, so we werent able to test the car with new tyres and wheels!!!

i might look into the discs being out of balance. will a simple machine of the discs pick up on this?

The commodores are well known for their tailshaft center bearing crapping its self, especially the VN's. :)

They will send a vibe up through the steering wheel on accel and when it gets worse on cruise. I had mine done on the VS 5ltr twice, they don't last too long.

My tail shaft uni joint is shot to hell in my commodore. It shakes the steering wheel to the shit house.

Change the uni joint. Problem gone.

Regarding the shake at 110km/h. I had that with my old gearbox in fifth gear. Drop it back to fourth and there was no vibration. The vibration you could feel up through the seat and slightly on the floor pan. It would slightly vibe the revision mirror where it was difficult to focus in on cars behind.

New gearbox after it stripped third gear and no more vibe.

So try that.. Get it vibrating.. Drop it back a gear and keep cruising. :)

before you spend another cent swap all 4 wheels with another set even if you have to beg borrow steal them just to test the car.

wheels are the largest ammount of rotating mass and will be the easiest/cheapest thing to fix/diagnose.

cheers :(

you would thing flat spotted tyres would be picked up in a simple balance?

A flat spot will just show that one side is slightly heavier, add weight to the other side. Problem still happens that the tyre goes round round round FLAT round round round FLAT.

Each time it hits a flat, it "hops"/"shakes"

Major badness!

the tyres on the front are brand new, my brother doesnt lock up the brakes

before i could suggest an on car wheel balance he has got the discs machined and said that its fixed 90% of the problem. yay. so its better then its ever been but im guessing there is still something there

thanks for your help so far, i wonder if the rest can be fixed too

hi there.. where did he get the disc machined, how much did it cost and how long did it take?

did he have to take the disc rotors out himself or just drive to the disc machiniing place and they'll do it all.

thanks

dont know any of it

but its hell cheap and they'll do it all for you and it doesnt take long

even kmart tyre and auto does that stuff! its like $20-$30 a disc, all labour included

but it'd be best to do an on car wheel balance, it would compensate for anything being out of sync. -unless you are getting vibrations when braking (warped discs, fixed by machining / new discs)

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
