Crazy....

Here's my next question - Mechanic says I can drive it - and I should be fine... Is this true? Do I need to baby it?

You're be fine. Long as you don't do any hole shots, and side stepping the clutch.

To change to bushing out. You're looking at at about 6 to 8 hrs of work. Depending on skill set. To drop the diff. You got the exhaust, drive shaft, axle shafts, frame bracing, sway bar. It's best to work from the front of the sub-frame. Install the new bushing from the front. Push it all the way in. Until the front of the bushing is flush with the sub-frame. This should get you where the diff should be. Bunk had to drop his diff a second time, and push the bushing a little deep to get the front 2 bolt holes to align up.

I pushed my Z1 bushing in from the back; used a bigass washer and a piece of angle iron and a long bolt w some washers and nuts and whatnot, and ratcheted it into place. Lots of threads here on ways to do it.

Don't go to a dealership. Find a reliable, trusted, and credible mechanic. The pics clearly say its your bushing. Your butt and your ears will tell you if there's a driveshaft issue. When bushings fail, dealers will replace the entire assembly vs just the bushing. It is quick and heftier on the cash register.

Good to know!

Thanks - I feel like I’m being had even though it’s a buddy of mine. Seems like it’s more of the protocol - like you said - when bushing goes - they want to replace it all - even if it’s ok.

If warranty doesn’t cover it fully - I’ll be passing on it. Like I said - car drives perfect 👌

If you are able you can replace them yourself. It’s really a lot easier than most people think. I have a video replacing mine on my YouTube channel RiceburnerZ https://youtu.be/aWZI15smSzw

It's easier if you would have gone in from the front. ;)

What about adding a aftermarket diff brace that bolts the diff to the subframe in the meantime so the diff isn't bouncing around in the broken bushing?

Wouldn't this prevent the bushings from breaking in the first place as well?

Yo. I ended up getting some bushings, upgraded cover, and brace from z1 ;) already installed and oh so nice.

Bushings
 
I'm planned on having a Quaife diff put in my base 370z. With the new diff being installed, would installing the Z1 Motorsports Urethane Rear Diff Bushing Set be any more work?

I got the z1 cover + urethane installed - I’m pretty sure it was a smart move to do all at the same time - if you’re having one thing done - might as well have the other.

Get both lsd and diff bushing done at the same time. Since you have to drop the diff anyway. The diff bushing will tack on a few extra hours on the labor. Time to do it depends on your mechanic's skill set.

Thanks for the info guys!

With the diff already out, how come it takes a few more hours to replace bushings? I'm just a noob at this but curious? And I hear a special removal tool is needed?
