Infiniti G37 Differential Bushing Replacement

[@kenrickwilliams6527]

I did this job this weekend and wanted to add a tip to anyone else....freeze the big bushing overnight...makes it SOOOO much easier to I stall. The freezing shrinks the poly bushings just slightly but makes a HUGE difference. I spent 2 hours trying to hammer them in...got 80% in...couldn't get last 20%...so I pulled it froze overnight and next day I could push in 50% by hand and very easy hammering the rest.

[@mohamedhosini2103]

But how could you freeze it up while it’s in there?!

[@v36vhr]

@@mohamedhosini2103 he took it back out and froze it and then reinstalled it

[@videomaniac108]

Thanks for the very clear explanation as to what's involved in this. I have a 370Z that has the diff bushing with a small tear in the rubber. I haven't noticed any differences in the sound or feel but I know I will have to change it soon. I'm going to go with Z1's complete set of diff bushings, as I like their products. This video makes me feel much better in knowing what needs to be done.

[@fernandoboschelli2976]

Just a quick tip follow the instructions from whiteline if using them on g35. Car was vibrating very bad by putting the thicker bushing on the top, after re installing the thinner bushing on top of the dif now the car runs very nice

[@elcolin_]

Mannnn you make hammering out the bushings with that 36 so easy. I'm over here on day #2 trying to beat these things out

[@sammcrown]

Haha. They should come out fairly easy as long as you are using a heavy hammer. Otherwise it will be much harder. Good luck!

[@NG-VQ37VHR]

I'll be doing this next weekend on a sedan. I'm real jealous of how much room you have at the rear of the bushing. I'm hoping the z1 removal tool will make this job not so bad.

[@tonycstech]

Thanks. Needed to replace the cover but it wont come out without removing the entire thing. sucks but no choice.

[@jjwalker2011]

Like a boss, nice work! You saved some major coin.

[@NovapartsLLC]

Great video. Going to replace on my FX45. Will get the sawzall ready

[@sammcrown]

Good luck. It’s a good learning experience!

[@v36vhr]

@@sammcrown did you remove the rear sway bar?

[@sammcrown]

@@v36vhr Yes, had to remove it.

[@dgree100]

I’ve been thinking about changing mine bushings too. Now i known how long that will take

[@noctrno]

Hey, thanks for the video. Did you notice any difference in the cars handling w/the new bushings? How about noise? Does the rear diff make any noise with the new bushings? I want to make sure i get the right replacement bushings for my 350z.

[@sammcrown]

Not at all. It rode great. Solid product!

[@faizimran2715]

Hey at the moment my rear diff is all disassembled and I’m slowly removing the bushing in the subframe could you tell me where you found the torque specs ? Or did you just tighten till they were “tight “

[@sammcrown]

Faiz Imran I googled it. I believe they were around 80 ft lbs.

[@faizimran2715]

sammcrown I tried and didn’t find anything specific could you please send me a link or something because I can’t find a good guide

[@faizimran2715]

sammcrown and 80 ft lbs for the driveshaft , Axels , and the bushing screws ?

[@sammcrown]

Faiz Imran here is what I referenced for mine as it’s the same my350z.com/forum/engine-and-drivetrain/591514-torque-specs-for-differential.html

[@faizimran2715]

sammcrown THANK YOU SO MUCH!!😭 I spent the whole day with freinds and we only got the stuff off because I had a motordyne and a lot of small mods from z1 that made taking the bolts and stuff off very difficult but you have any extra tips ?

[@fagan900able]

The sub bushing come out on what size the way going to the rear or the the front of the car

[@notsamul_8293]

so helpful

[@sammcrown]

Thanks. I could have done a better video but I just wanted to get through replacing those darn bushings lol

[@MickeyWu7r5]

How is the Super Pro bushings holding up over time? Can you drive aggressive and feel a difference?

[@sammcrown]

I can’t comment on that as I sold the G. Hopefully it’s holding up well! :-)

[@ManuelTorres-pm8el]

Do the new bushings slide in nice and easy or was it a pain?

[@sammcrown]

Manuel Torres New bushings were easy. Old rear differential bearing was difficult to pull out.

[@Dragandspinn]

Was the replacement bushing not as long as the OEM? Didn't look as though it was flush with the back side of the sub-frame.

[@sammcrown]

Hey there. It may have looked that way in the video but it was pretty spot on to OEM size.

[@Dragandspinn]

@@sammcrown yea I figured as much. Great video. I ordered the bushings right after watching! Thanks.

[@yorkiepit]

Awesome dog

[@mohammedabujalghif5690]

Is this bushing will fit on FX35 2009?

[@ZackMax84]

Any chance you can share the torque specs?

[@BigSoWat]

He put them in a different comment in case u didn't find it already

[@Terry1212]

How do you get the diff out with the driveshaft in the way? Do you have to like push back on the diff and tilt the front of it down at the same time?

[@sammcrown]

Terry1212 basically I had to push the front slightly forward then down to get the rear bolt out of the hole that holds the rear of the diff in place. I did this all on the jack as I was doing it myself.

[@lukestevenson5479]

should still always do fluid when it’s in the vehicle

[@ajl0426]

Has anyone done this in an M37 yet? I have a 2013 and it's leaking but nobody can confirm that the bushing for a G/Z will fit.

[@torvarrisevans7254]

Hey bro , did notice any performance benefits.

[@sammcrown]

No improved performance. Just smoother shifts. It’s a manual

[@torvarrisevans7254]

@@sammcrown ok thanks.

[@MrColourclassic]

How are the superpro bushings holding up? Any complaints?

[@sammcrown]

joseph_dw They have been great up until I sold the car so hopefully still doing good.

[@akaSouths]

how do you know when the bushing is “bad” just from the leak? and the thud when u shift gears a certain way?

[@sammcrown]

South yes, pretty much exactly that!

[@Dragandspinn]

Yea I just recently started having a thud in the lower grars!

[@sonicmartinez3218]

How did you get those half shaft nuts out

[@sammcrown]

It was tricky. This video has a good view of it being removed. kzbin.info/www/bejne/oqmTiparYr2abac

[@israelreyes8970]

What size clamps did you use ?

[@sammcrown]

I’d have to measure or take a pic but I’d say the c clamp measures 10 inches in length by 5 or 6 inches. Big enough to get around the front and back of the sun frame to push the bushing into the sun frame sleeve. I bought it at Harbor Freight.

[@sammcrown]

Just checked. I used a 6” c clamp.

[@bigbabyjune]

what state u from?

[@vasilikharabadze141]

Hi,you know this bushing part number????for q50 awd

[@sammcrown]

I do not. You can try contacting www.z1motorsports.com/

[@dgree100]

What kind of muffler tip do you have?

[@sammcrown]

dgree100 Tanabe Medallion Touring catback

[@robertbarba3948]

Will this solve the issue with wheel hop?

[@sammcrown]

Robert Barba Not sure what wheel hop is referring to. This will eliminate the jerkiness when shifting from 1st to 2nd for example.

[@beepbeeplettuce2137]

dealership wanted 1.3 to replace mine lol

[@syncross7530]

Use a 35mm socket or it will get stuck

[@ClaudBol]

DAM bro you didnt show the install . waited this whole on the video for you to skip it

[@sammcrown]

G37 CB sorry bro. I wanted to hear Axle sing Sweet Child of Mine too on your vid but was drowned out by someone 💁🏼‍♂️
