You should do a 4.09 final drive diff upgrade video. Include testing of 0-60 before and after. There’s alot of mystery out there without any hard numbers besides a handful of forum posts from over 10 years ago. Almost nothing on KZread either. If people knew the 4.09 or 4.36 gears can drop the 0-60 on a 350z by a full second, people would be buying more of these. Suggest you do it on a DE car. Testing 0-60 before and after with the dragy app.

Just when I’m in need of a diff bushings z1 has came thru with a detailed vid 👌🏼

You got extremely lucky. I was smacking those bushings out for about a half hour. Then I finally brought out the air hammer and torch to help. Still took some time. Pretty sure mine were worse than normal though.

So I'm attempting to remove my differential and the 17mm nut that screws onto the diff cover will not budge. Breaker bar, PB blaster, I even jacked the car up by the diff just enough so it wouldn't twist in the bushing and it's starting to round off. Has anyone had one as stubborn as mine? Any ideas? I'm tempted to unbolt the diff cover and try to rip it out!

Y’all always leaving jerseys on my clean floors when y’all work on David’s car.

how much would this whole job cost?

I have never heard of scotchbriteing the new mating surfaces. Is this something you should really do?

If it's a brand new cover, it is not required, but helps the RTV create a good seal.

Gotta put some anger behind Wilton!

I can’t get the mounting bolts to go in at all any solution?

Your captive washers in the subframe may be stripped. In that case, the only solution unfortunately is to replace your subframe.

They aren't threading in, or you can't line the bolt holes up with the new bushings?

I need this done to my G35 from Jersey and mine looks like that also, I should bring mine down since you are good with rusty cars from Jersey 😂

Wouldn't the top hole be a fill hole? Bottom is drain and top is fill

With the Z1 Dif Cover, you get a fill hole (top), drain hole (bottom), and an additional hole in case you want to install a diff cooler.

I think that's worse than the "z1 test car" Jon bought from me back in 2018
