yeah reading up on them in the last 30 mins or so i have heard the same.
I don't want to go solid though.
I daily my car and have yet to take it to a track (not sure if i ever plan to)

So it's hard to see in the pix is the bushing rotted or is the bolt missing?
How are the 2 bushings that hold the input of the diff to the subframe??

it sits back in there, and i think it dry rots and then oozes the goo out. i have never personally seen the ears blow out, just the subframe one

When mine failed and I swapped to the whitelines, I still had that highway vibration that came and went above 80. Never did figure it out.

its in there.
It doesn't matter, all of them will be changed out.

I think im going to swap the trans bushing as well

That sucks. This almost inspires no confidence to swap out the bushing...

I don't remember when the vibration started honestly. I've changed wheels/tires after and no difference. I'm assuming it's driveline, as Nissan put a trans in the car once under warranty, and I took it out for a clutch install later on down the road. So i'm guessing after one of those jobs the driveshaft got clocked wrong or something, or maybe it didn't like the aftermarket flywheel. It really only shows up past 80mph though so it's hard to troubleshoot.

well as in a previous post, at 30-35 i can feel a physical bouncing and also a vibration before 80. So swap out bushings, make sure the car doesnt rattle around, then trade it in.

Lol I just didn't worry about it, I don't spend a lot of time cruising above 80, and when I was racing a little vibration through the shifter wasn't really gonna get my attention. The low speed bouncing may be from the failed diff bushing, that I can't say. I started to notice increased wheel-hop on hard launches, found the bushing leaking, replaced it.

what bushing did you replace it with?

This is interesting.

My car only has 58k as an 06, but I may consider changing the rear diff bushings cause of the symptoms.

To reiterate. at and above 75mph (comes and goes) I get a vibration that almost makes the car feel less attached to the road. Disconnected so to speak.

It is frustrating and after storage this winter I think it will be first on the list. Keep us updated guys....

you feel it in the steering wheel or in your butt?

black38

iTrader: (1)

in my butt mostly, slightly in the shifter

travlee

might be trans mounts... and you double checked nothing is wrapped around the drift shaft right

black38

iTrader: (1)

i did double check that there was nothing wrapped around it.

The mechanic that did my diff bushing. He said he did all he could to see if it was bad (read:shook the ish out if) and there was no play.

I had this problem on a Mustang. It turned out to be a bent or unbalanced drive shaft.

I replaced the drive shaft and u-joints and the problem disappeared.

While towing, was it on a dolly? Rear wheels on the ground? Did you ever remove the drive shaft in this car ?
