The OEM bushing has a small lip, maybe 1/32" wide, that goes around the ID on both ends of the bushing. It makes the hole look a little smaller, you can see it as a lighter area if you look at the top of the photo. Real world I'd guess it's there for cosmetic reasons to make the ends look compressed when installed.

I tried to measure the hole with calipers, but split rubber doesn't make it easy, let's just say they're close. If I'd thought of it I'd have put the bushing into the metal bracket that surrounds it to see if I could get a better measurement. I also considered the rubber could be a different compound between the two and that might be the cause of the difference in driving feel.

Just a Hunter I'm happy you resolved this problem.

Longboardr Drove it in the driving rain Friday, towed in blustery wind yesterday and the missus is driving us home pulling the enclosed trailer today. I can't say why but the OEM bushing has made a world of difference. I never would have guessed that piece of rubber could have affected the steering/feel this much.

Longboardr Installed the OEM bushings tonight. The only noticable difference besides where they're split was the OEM had a narrow lip at both ends that made the hole slightly smaller. I'll need some time to see if they've made any difference since how the X felt changed with weather conditions. At the worst I spent $13 so I don't have to look at the big gaps anymore.



OEM on the left, Moog K200347 on the right.

General_Tarfun Those are the old design and also look too small, over the years Nissan changed them to have the cut at a 45 degree angle where the bushing meets the frame.

whatnext The bushings that hold the sway bar to the frame are only there for that reason. Why they are rubber or other elastomer is for noise/vibe isolation only. The sway bar acts by twisting action on it from the opposite ends. The bushings are not gonna grip the sway bar tight enough to increase the twisting force (torque) in the sway bar. If the mounts are sloppy enough so that the sway bar rocks a little, that will decrease the action of the sway bar.

Longboardr Thanks for the input @Just a Hunter. Bushings are cheap, so yeah, best to just replace with OEM since I was happy with them before. Fwiw the part number for my '11 was 54613-ZL10A as given by my local dealer so that's what I'll be putting on. I wish I hadn't thrown away my old ones now so I could compare them, but I'll do that with the new OEM's vs the Moogs and update the thread.

Just a Hunter Based on my research, it appears Nissan made a change in their stabilizer bar bushing design at some point.

If correct, this should be the new part number
54613-ZV50A

Pretty cheap off amazon
