It's really nice to see all the performance stuff you're doing on these Nissans. I have a 370Z, and so much of what you do on the Qs and Gs is applicable to mine. I had the Whiteline poly diff bushing set installed on my Z by a good shop in San Jose, CA and the improvement in the feel of the rear end was noticeable; my shifting also got better. My next project will be the slotted Akebono two-piece aluminum hat brakes for the Z, for an even greater reduction in unsprung mass. BTW: My last duty station when I got out of the Army in 1970 was at Ft Jackson, just outside Columbia. I used to like going to the town and going on long walks, to see some of the interesting historic sights.

If I had a suggestion for this, I would definitely say it wouldn't hurt to invest in an oscillating tool to cut out the rubber section of the bushing. It would probably cut through like butter and be very easily controllable. Very nice job documenting this job!

@SpeedCultureStudios

Жыл бұрын

It might be worth a shot. I have one, but the blade is too wide and flat. If there are more narrow attachments, that might work--as long as it cuts the rubber and doesn't melt it. The chisel actually worked very well. I would also say that a small air saw for cutting the metal sleeve might be better than a reciprocating saw too.

@@SpeedCultureStudios The melting is a solid point, dealing with such a soft rubber.. there are very narrow attachments out there, but as long as the chisel works, no need to mess with a working system. I think a reciprocating saw is a pretty crude tool, so to me, I would probably just use a hacksaw to cut the relief strips, and then use a pry bar to bend the rest out of the way.. appreciate your response and quick action on creating this video!

I just did this on a '13 g37 sedan a day ago. Holy crap was it a nightmare. You have almost no access in the rear because of the truck's floor. It comes down much lower than on the Q50. Just enough a sneak a ratchet in. If you have access to a lift, I think the job would be much easier. But if you're gonna be on your back, anyone thinking about doing it had better be prepared for the undertaking. It's all super easy until everything is out and it's time to remove the rear bushing. I spent a half day just trying to press the bushing out with the z1 tool, 2 clicks of the ratchet at a time due to clearance issues. All that said, the car feels so freaking good now under hard acceleration and normal driving. I'm not sure I'd do the job again though.

I did the thr opposite with mine. The only bushing bad in mine was the sub frame one so I filled the opening were the original fluid filling was with quick set epoxy so I still have the rubber portion as "flex." I basically made a circular dam with a small hole in it big enough to allow my epoxy tip through it (like a straw on a cup lid) and filled that outer ring. Made a WORLD if difference, took 15 minutes, and about $6.00. Definitely not as good as a complete new bushing set but for those who don't wish to go through all of it, that does the job. Did it two years ago and it looks like the day I did it.

good job. Do you know what DIFFERENTIAL BUSHING i can use for my 2009 fx35 rwd suv? AND are in the ORLANDO area, or do you know of a good mechanic in this area? thnx.

My '16 RS AWD started behaving rather consistently inconsistent, seem to be losing power with no DTCs, or background chassis control codes, abs etc. Than tonight I'm accelerating through a turn and the rear axle literally felt like it was coming loose from the chassis. Of course I'm counter steering, jerking the wheel, for no reason, I'll add. My pride and joy sure enough needs the rear differential bushing. She's only got a little over 110k miles on her, all four of my DDS struts/shocks are leaking and toast... Having come from the VQ platform to the VR is definitely night to day. I should have prepared for the DDS failures months ago, and no I'm not going coilovers,i actually like the handling characteristics the Monroe DDS struts/shocks give the chassis. I'll be ordering the Z1 bushing prolly tomorrow, I'm dreading the install. But so far in the five infiniti's I've owned, I've never taken any of them to a shop except for wheels, tires, and alignments. Thanks for the video! Also will a 3" hole saw be big enough diameter to remove the rubber insert?

@SpeedCultureStudios

9 ай бұрын

You can handle it! A hole saw is a good idea. Even just getting the bulk of it out will give you room to cut that metal sleeve.

Do you suggest putting the Z1 rear diff brace on after installing the Z1 rear diff bushing kit? Or the subframe bushing collars? I have a failed rear diff bushing on my 18’ Q50 RS, getting the bushing kit professional installed here soon. Thanks! Great videos 👍🏻

The diff bushing kit will make a huge difference in its own. The collars are a big upgrade too. The brace wouldn’t be as necessary after the bushing kit, but will still add some additional rigidity if you’re looking for it!
