14mm socket
17mm socket
17mm deep well socket (for the nut on the rear side of the diff)
3" and a 6" extension
1/2" breaker bar (ratcheting style is very helpful)

Watching you guys do these mods has given me the confidence needed. I would've never attempted to do most of these tasks before watching your vids. Awesome 👌 I appreciate you guys tremendously!!!
Thank you for the kind words!! This is exactly what our channel stands for and how we hope to help others just like yourself! We are the First Timers so we like to take on challenging tasks such as this for the first time and showing the obstacles you may face that others may skip through in their videos. It may look unprofessional to the viewers but we aren't about that, trying to be real. If and when you attempt these jobs, make sure to have a helping hand! It's possible to do by yourself but man would it be 100x harder. We appreciate you as a viewer!! 🙌🤝👍🤜🤛
Thanks for making this video fam! Im not looking forward to doing this job but y'all giving me more encouragement. Blessings and good health to you and yours!!
Thanks for commenting! It was a real pain but it made a HUGE difference in shift feel. I would imagine it to be even better if you go solid bushings but might be overkill for a daily driver. Good luck when you take on this task and if you have any questions, hit us up!
If you own a G35 or 350Z and drive it spiritedly, this is a MUST DO! The performance improvement has to be felt to make all the pain and suffering worth it lol. Seriously. 🤣
Yup it's a dreaded task but well worth it!
Did you upgrade the sway bars or are the factories ok? I’m doing the front suspension today and I’ll do the rear in a couple weeks. Great video
The sways were left stock. I believe on the 05+ models they were made slightly stiffer than the 03/04 model years. To complete the setup sway bar upgrades is recommended but I'm satisfied with how it feels considering I drive it on messed up roads. Upgraded sway bars would make the ride stiffer but would definitely help while cornering in the canyons. Thanks for watching! Glad you enjoyed the video!
the bushings on the diff. , come out with just a hammer , really easy
Everything on my G35 has been a PITA to work on. Thats why we had to use the hydraulic press.
But thanks for the tip. Hopefully it will help anybody else who is trying this job.
I’m using that diff bushing and is a pain in the ass, tomorrow switch to whiteline 🎉
Hi there and thanks for your comment! What exactly is a pain with the Prothane diff bushing? I haven't had any issues yet at least.
@@FirstTimersChannel yes the differential tends to jerk when you reverse gear or want to go slow, bought this one becouse was cheap but was a mistake, now spend more money and time 😓
Hmm I think I know what you are talking about. I just was thinking it may be my old engine mounts or trans mount causing a little slop. Also stock 2 piece driveshaft. But do let us know if changing to white line helps your issue! I'm curious to know this. Thanks!
@@FirstTimersChannel that’s for sure bro
@@FirstTimersChannel it feels very smooth 100% white line bro
cut the center bushing with a sawall , around then , cut the sleeve separate , with the sawall , cut lines in it then , tap it out with a punch , cut 2 lines , then
I did what I could with the tools and access we had. Never want to do it again lmao. I would rather drop the whole subframe and do it like that.
@@FirstTimersChannel You did a great job , learned a task
@@koachs77 Thanks! 👍
3/7/2024: Do you know if this bushing will fit the FX35 2009? Or could you say where you got this bushing from, so I can try to fix my infinit fx35.? Thnx.
Not sure of the sizing for the FX35 but I got it from the Prothane website www.prothanesuspensionparts.com/141603 See if they have one for your model
Bro I literally have the Z1 kit and it’s taking a huge amount of force to get the outer sleeve out. Almost impossible on your back…
I hear you! Heard the Z1 kit was supposed to make it easier. I can't say for myself as we made a make shift kit. Tried banging it out with a chisel but trust me the hack saw method got that outer sleeve out for me while on my back lol. It's a huge PITA and I more than likely will never want to do that ever again on any G35 unless the whole rear subframe was dropped off the car. Good luck man, just keep at it. Imagine how much you're saving right now by doing it yourself. That usually makes the blood sweat and tears worth it 🤣
@@FirstTimersChannel Yeah I just gave up on it and used a saw. Cars in the driveway ready for a cruise tomorrow 😎
@@ripple1217 Nice good on you bro!
How many miles on the car? I didn't see any evidence of leaking fluid from the bushing but it can fail anytime. One hammer blow can take out the two front bushings. The diff bushing is another story. You can drill it out, burn it out or use a sawzall to get the bushing out. Many use a sawzall to cut the bushing shell and then bend it in and remove it. There are handles for hacksaw blades. Too bad you didn't show the finishing of the Diff bushing. I was curious to see the retention method on the bolt as Prothane wants you reuse the OEM retainer and about every other company has a washer that goers inside the bushing and maybe a sleeve. But the Prothane bushings are really inexpensive compared to every other supplier.
The car has 151k on it right now. I've read that the diff bushing is filled with fluid and that if you don't see any then it must have busted a long time ago and has since washed away.
In response to the retention method, you do use the OEM sleeve. You can see me holding the sleeve here => th-cam.com/video/pOKRKfVErkY/w-d-xo.html . That gets pressed into the diff bushing, no washers were used. You then use the stock nut, if I remember correctly it was a 17mm and you'll need to use a deep socket 17mm to reach it due to the stud.
Another thing to mention... there is a comment below from "miguel galvez" who claimed there was a small lag, slack feeling when shifting. I too feel the same being on the Prothane bushing. He has since changed to Whiteline and is liking it. I was just going to get a diff brace instead of changing the diff bushing out.
After seeing a video of the Z1 bushing flexing under acceleration, I would go for the solid or semi-solid bushing. Even with urethane, the entire rear assembly twists too much.
@@amazoidal Agreed! I still want to change my engine and tranny mounts to see if it helps any.
Honestly I’m struggling to fit the diff back in lol, the two bolts on the diff aren’t lining up for me😭 it’s like just barely off
It helps if you have another person to push up on the diff while you align the holes. If you're by yourself, use a jack to hold it up and use a big flathead screwdriver. Put it through one of the bolt holes and try to pry it into alignment. This task was hard for me too man. I feel your pain!
First Timers Channel ok cool I’m def gonna get to it later today and try that out, taking me way too long to finish this lol so HOPEFULLY it goes in and everything will be cake. Thanks!
@@CcS2o9 Sometimes it helps to take a breather. When we were doing the subframe bushings on this episode => th-cam.com/video/SHgCKBfkpEA/w-d-xo.html we had to step away for a minute to cool down from the frustration lol. Just know that it will get done! Believe! Just think of how much you're saving by doing it yourself lol that always works for me. 🤣👍👍 Plus it's fun.
First Timers Channel I took one day off but here I am trying again right now I literally had the bolt right there but it didn’t thread in, so once again I’m stuck lol I’m not having a fun time at all now🙃
@@CcS2o9 If you have an air gun or battery powered impact.. it may help with driving the bolt through if you have it close enough. It's hard to use a wrench while trying to hold up the heavy diff in position at the same time. Just make sure to grab a couple threads first to avoid cross threading.
I think prefer to pay, how much you think is the labor of this
Went to a few shops for a quote before doing the job and was quoted $1000+. So I said hell to the no and did it myself. The rear subframe is like $3k+!
Are there front diff bushings??😊
For the diff, just the ones you see in this video. Anything forward more would be the transmission bushings
The masks tho 😂
Yup at the time they were a mandate in California. If you watch any of our new episodes we aren't wearing them any longer.
