Rear Right Side Serious Virbation after 60mph

[IJ.]

Heading out to the shed now, try swapping the fronts and rears and let me know if the vibration is still there, I'll stick my head in at lunchtime.

Also sight along the driveshaft and make sure the Uni's are in line.

Ok, well I checked the fronts and the right front tires weight isn't there! But Would this cause the rear to vibrate so much?

 

[SupraMario]

Well since its freakin sunday, it looks like all the places that would mount and balance, are closed. Fuuuuuuuuuuuuuuuuu

 

[SupraMario]

Ok, found a place to balance the tire, balanced it. But didn't fix the issue! FUCK!!!!!

So you didn't swap the wheels around like I suggested?

No, I can't only have one jack here, gotta get my stands >< ><
I think the rear wheels are the issue, going to get them balanced in the morning.

To much work its dark outside, and tomorrow I'll take it into NTB and have them balance them for free, since I bought them from there.

Lugs where on there, hubcentric rings??

allows the rim to be centered by the hub, not lug nuts. Its a bit more in depth. Google it.

On my rims one required a different ring then the others. Nasty vibs at highway speeds until the rings were swapped around.

I had a right rear shake above 80mph.
Thought it was the carrier bearing, so replaced that.
Shake was still there.
Seemed to be a little (very little) looseness in the right half shaft, so I changed that out, and now shake free........

Yea I doubt these have it, considering they are just cheap ass 1 piece ADRs.

Ok Im pretty damn sure i found out the issue,

500 (36, 49)
The right side rear bolt holding my LSD to the car is MIA!!!!

So Can someone tell me the washer/bolt size pitch/thread for it!
I hope its a standard size bolt, so I can get it from autozone.

I recommend just getting the bolt from Toyota. That way you know it's the right size, and it's no more than 3 dollars. Cheap assurance

I will, but I need something in its place right now.

Ummm "500,36,49" is the torque spec for the drain plug??
(kg-cm,nm,ft/lbs)

If one of the front mounting bolts is missing it's a symptom of the vibration and not the cause.

Its not a front one, its the rear one near the main part of the pumpkin. I should have taken pictures of it. Well, its a cheap fix to continue to debug this.

Might be an idea to carefully inspect the subframe for cracks Mario

Yea I did, had it up on the lift and no cracks, this is why I'm trying to find out the correct bolt to go in its place so I can get the car home and call champion to send me a new bolt.
